Average drinking water consumption is ~2.5 l/person/day: http://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/water/art-20044256 Water in LD costs $0.75/l (last year's data). This means that a 4-person family would spend $274/year. This means that $255 Lifesaver Jerrycan will pay for itself in a little less than a year. Can we get it wholesale? Jerry Can processes up to 20,000 l. A family of 4 consumes about 913 l/year. This means that the can last up to 22 years!.

Lifesaver bottle, $168, processes 6000 l: http://www.amazon.com/gp/product/B001EHF99K

Lifesaver bottle will last up to 6.6 years and pay for itself in 7 months.

Executive summary: 1) VFD cooling system commissioned and tested. System rewired to run w/ the VFD. 2) Chlorine demand and coliform tests completed 3) Heath assessments completed 4) Distribution system water flow tests completed 5) Meetings w/ ADESCO (president Santiago and and treasurer Cecilia), Morena (public health), new doctor at the clinic (Tania), and principal at the school. 6) VFD/pumping manual is being updated. 7) We did not document Chilo's routine (he does it over several days while we were busy w/ other tasks). However, ADESCO is aware of the issue and interviewing candidates for the "valvulero" trainee. 8) We inspected the valve boxes and the new tank.

Some challenges we faced: 1) Water from the pump is not reaching Tank 1 (now fed only by the spring). We started the investigation and had a section of the supply pipe excavated. Chilo and ADESCO will continue the investigation. Under the circumstances, the new tank somewhat compensates for the water shortage. 2) The booster pump seal is leaking, squirting water above the cistern. It has to be looked at. The booster pump check valve is not holding (it had this problem before; possibly got worse; cost of replacing $600-$700). The seal leak is probably a more serious issue as the backflow can be controlled by the manual valve. 3) We managed to get the VFD work done despite the power outage.

See details below:

Day 7 (the last day)

We met with the president of ADESCO and discussed the issues in detail. We also met with the principal at the school and discussed the filter issue and met at the doctor at the clinic discussing health issues in the village and new thew filter for the daycare. The old filter broke the previous day; some kids are bringing their own water; others drink water directly from Tank 4 (new) and the Tank 5 (the blue overflow); water is negative for coliforms. FIMRC may close the clinic due to lack of volunteers (caused by perceived gang violence in the country): http://www.fimrc.org

In the afternoon we went to Boqueron and Mercado de Artesanias,

Day 6

We patched up the holes in the cistern and the house wall left by installing the cooling system piping. We visited the school, and did q coliform test there (negative; they have to change a filter now used for a year) and then we followed Chilo running flow flow test and additional heath surveys in areas served by Tank 1 (now filled only by the spring), Tank 3, and most importantly the new tank, about 10 households We will summarize the details later but all houses receive water abundantly (1 l in 4-6 s).

VFD cooling: We had a power outage yesterday. Today we successfully commissioned the VFD cooling system (see picture above). We are now running the pump w/ the VFD while maintaining the VFD temperature below 104 F. We also fixed the low level switch issue and measured and reduced the flow rate off cooling water to 5 GPM. The system is ready to run from now onwards. We explained the use and advantages to the ADESCO's president and Vincente.

Water testing: Today we completed the chlorine demand and coliform tests for the home served by thenew tank. The demand tests (see Excel file below) indicate little demand. For the water that was one day old (recieved at the home on 5/11 and sampled on 5/12), the demand was zero. The demand for the 4 day old water (received at the home on 5/8 and sampled 5/12) there was about a 0.3 mg/L to 0.4 mg/L demand at 60 minutes and approximately 1.0 mg/L demand at 24 hrs. This suggests that 2.4 mg/L of chlorine must be added to have 2.0 mg/L at 60 minutes and 1.2 mg/L of chlorine must be added to have 0.2 mg/L of chlorine after 24 hrs.



The coliform tests suggested a slightly different story. Both samples contained significant coliform colonies (20-30 colonies in 1 m/L). Photos of the 3M coliform Petrifilm results for the one day old water are shown below.



Day 4 Today, we sampled water from a home served by the new tank. The home was located 2 houses down the road from the Day Care Center. At this home, water is stored in multiple containers. The white barrel (see photo below) contained water delivered yesteday. The blue barrel contained water delivered last Friday (5/8/15). Testing of these two sources (for chlorine demand and coliform) was begun today and will be completed tomorrow. The home owner here indicated that the water community water (delivered from the new tank) is used for everything (cooking, washing dishes, showering, etc) except drinking. Drinking water is purchased in 5 gallon bottles at a cost of $2.40 per bottle. The home uses 1 bottle per day.







We planned to sample the new tank on Monday 5/11/15. However, the tank was filled and emptied before we had a chance to get a sample. So we attempted to sample the new tank again on Tuesday 5/12/15. However, before the pump could be started power went out at the pump house. We will try to sample the new tank again tomorrow and will also post the coliform and chlorine demand test results for the home.

Day 3

Trenching and tie-ins done. Tomorrow test.


 * Trenching:**

The coliform samples were read today and no coliform bacteria colonies as shown.

The Excel file below contains the data to date and plots which show the test results at 60 minutes and at 24 hrs. Based on these results, it takes approximately 2.4 mg/L of added chlorine to achieve 2 mg/L at 60 minutes and it takes approximately 2.0 mg/L of added chlorine to achieve 0.2 mg/L at 24 hrs.



Below are some photos of Kat prepping the samples and determining the chlorine concentration.



Day 2

We met with Santiago Acosta and Chilo. ADESCO is looking for a second "valvulero" trainee.

We successfully installed the VFD cooling heat exchanger and mounted the panel back on the wall after drilling additional penetrations to move the panel to find space for the blister.

The new tank is being routinely used. We plan to test the water in this tank this trip. Today we took some water samples at the cistern. 3M Rapid Coliform tests were run in triplicate. 1 mL of sample was added to each of three Petrifilms and stored in the dark in the Community Center for 24 hrs. The temperature was not directly monitored, but air tempoerature was reported as 85-90 F (29-32 C) which is within the rang of acceptable temperatures for these test kits. Results for the cistern are reported in the day 3 log.

The cistern water was also tested to determine chlorine demand. When chlorine is added to water it will first react with organic matter, then reast with iron, manganese, and other inorganic matter, and only after these reactions occur will it react with and kill bacteria. In order to know how much chlorine to add to water you need to know both the desired end concentration and the 'demand'of the water. So in these tests, a known amount of chlorine is added to a sample of water and then the chlorine level is tested after 60 minutes and again after 24 hrs. The WHO goal is to have approximately 0.2 mg/L of chlorine in the water after 24 hrs. Results are reported in the Day 3 log

Two additional problems emerged: (a) water does not reach Tank 1; (b) booster pump is squirting water above cistern, possibly b/c of the seal leak (see below).

 AAB comment - here is a link to VFD cooling options: http://www.vfds.org/vfd-cooling-and-ventilation-136857.html We can discuss it at the follow-up meeting.
 * Day 6 (Friday): **
 * Today was a testing day. We calibrated the VFD to optimum operating frequency for both the upper and lower tanks and collected volume flow rate data and the corresponding power usage data.
 * We discussed several cooling options for the VFD last night and determined that it will be necessary to make another trip to the site to implement the chosen solution. In the event that we select a water to air heat exchanger, we measured out the piping required to access the heat exchanger from downstream side of the booster pump. Well water temperature is 80 F. The control room was 91 F today, but we should count on at least 100 F for our thermal calculations.
 * We disconnected the VFD from service today and returned the power feed wires to across the line power. Automatic operation and off peak operation both remain ustable even with the VFD disconnected. We will leave the system in this state until we return and implement an active cooling system. Tomorrow we plan to train the operators in some detail on how to use the new system in the state that it is in now.
 * We went up to the soccer field and looked over the two tanks. The paint looks good on the side walls of the tanks except for the bottom 1 ft which is peeling back in sheets in two places. Black mold is growing on the bottom of the tank. We filled the tank about 1/3 full and checked for leaks after 2 hours and didn't see any. Tomorrow we will mix some bleach into the tank, flush it, then scrub and flush into the soccer field until it is clean. We also looked into the adjacent smaller tank and though dirty, it doesn't look to have much sediment built up inside. We will also try to clean that tank tomorrow as time permits.


 * Day 5 (Thursday): **
 * Today was a day of tidying up and testing. We split up into two teams. The first team picked up some wire at the electric supply store on the way to the site this morning then wired in the off peak circuitry. The off peak circuitry was tested successfully. The second team had a productive meeting with ADESCO (FIAT provided an interpreter) and explained how the new system operated.
 * Here is a quick summary of the ADESCO meeting:
 * We explained how the new system operates and the ADESCO folks were very receptive.
 * <span style="font-family: Arial,sans-serif;">Chilo showed us where all the valves are.
 * <span style="font-family: Arial,sans-serif;">The town collects about $1100-$1400 total from residents for providing the basic service.
 * <span style="font-family: Arial,sans-serif;">A total of $300 is paid to Vicente and Chilo for their services as pump operator and valve operator, respectively. Not sure how that is split between them.
 * <span style="font-family: Arial,sans-serif;">The re-wiring that occurred after the electric surge several months ago cost about $2000 total. They are still paying off the remaining balance of this bill.
 * <span style="font-family: Arial,sans-serif;">The pumps are run 18 hours per week.
 * <span style="font-family: Arial,sans-serif;">Vandalism is apparently a serious problem. As a result, many of the valves are purposely hard to access.
 * <span style="font-family: Arial,sans-serif;">The gangs are active in Las Delicias and are extorting villagers. Associated violence doesn't seem to be an issue.
 * <span style="font-family: Arial,sans-serif;">It takes about 2 hours for the middle tank to fill up.
 * <span style="font-family: Arial,sans-serif;">It takes about 6 hours for the upper tanks to fill up.
 * <span style="font-family: Arial,sans-serif;">Off peak hours are from 11pm to 5am as defined by the electric utility.
 * We ran the VFD for several hours today and found that the VFD generates a significant amount of heat that is not being readily dissipated with the 105F ambient temperature inside the control <span style="background: none !important; border-image: none !important !important; border: currentColor !important; display: inline-block !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; text-transform: uppercase !important; vertical-align: baseline !important; width: auto !important;">[[image:http://cdncache-a.akamaihd.net/items/it/img/arrow-10x10.png height="10"]] . The VFD overheats when the door is closed. Because of the risk of electric shock, running with the door open is not an option. This means that we will need to add active cooling to the VFD enclosure. We are investigating tonight what our options are for cooling and whether we will be able to get something installed before we leave.
 * One option is to install a heat exchanger such as this one (which would require another trip): **Thermacore 5360**
 * We performed some efficiency testing of the motors and found that the well pump operates most efficiently when the well line is partially constricted using the inline valve. We settled on the 4th notch from closed position. Similarly the booster pump operates most efficiently to the upper tank-- and at a compatible speed with the well pump-- when the VFD operates at 60Hz. We haven't yet calibrated the lower tank.


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 4 (Wednesday): **
 * <span style="font-family: Arial,sans-serif;">Today was a wiring and testing day. We stopped by the hardware store in the morning and picked up a replacement switch for the one that was broken. That ate up about an hour. We arrived at the site around 10am and went to work installing the new switch which is shallow enough to fix the clearance issue.
 * <span style="font-family: Arial,sans-serif;">Our next task was to re-wire the well pump cabinet to interface with our system and to add a manual-off-auto switch to that cabinet. This was installed and tested successfully.
 * <span style="font-family: Arial,sans-serif;">At this point we carefully photographed the existing wiring so that should the VFD ever have problems in the future, the local maintainers will know how to re-wire the system to bypass the VFD.
 * <span style="font-family: Arial,sans-serif;">Our next task was to wire in the VFD. We completed wiring, powered up the VFD, updated the internal settings with nameplate.


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 3 (Tuesday): **
 * <span style="font-family: Arial,sans-serif; line-height: 19px;">Today was a wiring and testing day. We stopped by the hardware store in the morning and picked up a few pipe fittings. We ended up arriving at the pumping site around 10am.
 * <span style="font-family: Arial,sans-serif; line-height: 19px;">Our first task was to re-wire the old control cabinet in order to (1) bring it up to American standards (2) allow it to interface with our new system, and (3) add in the new terminal blocks, indications, and switches. By 2pm we had re-wired the cabinet, labeled all the wires, and tested the circuitry for correctness. We tested booster pump operation and found that the motor starter requires 240V, not the 120V that we were feeding it with. We made that correction and tested operation of the pump successfully.
 * <span style="font-family: Arial,sans-serif; line-height: 19px;">Our next task was to test the level control circuitry which we had re-wired on the control cabinet side. Our initial test of the low level probe failed. Continuity testing suggested that our modifications were correct in the cabinet, but that the probe itself was failing. We pulled all three probes out of the tank and replaced them with new probes. The new probes tested successfully. We now have the existing non-VFD circuitry in a functional state.
 * <span style="font-family: Arial,sans-serif;">A replacement switch that we added today to replace a broken switch turned out to cause clearance issues with the over voltage protection device inside the cabinet. We will need to cover the hole and move the switch to a new position on the door. We plan to pick up a new switch in the morning before heading out to the site.


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 2 (Monday): **
 * Today was an installation day. We were shuttled to the project site by about 9am. We divided into two teams. Team 1 went to work discovering the existing wiring. This was necessary because since the time of our last visit, an electrical surge took out the soft start for the booster pump which resulted in someone re-wiring much of the control cabinet. Team 2 installed the new VFD cabinet on the wall adjacent to well control cabinet and added conduit power and control conduits between the two cabinets.
 * We left the site at about 4pm and stopped by a commercial electrical supply store on the way back to the guest house. We were able to purchase a new 24V power supply which we had been planning to use for control signaling, but which had been removed after the electrical surge. This part cost $170.
 * We returned to the guest house and based upon our observations from today, redrew the electrical schematic to interface with the new system [|Holiday Palace].


 * Day 1 (Sunday):**
 * Today was a travel day. Brian Hamill, Lisa Tuason, Barry Zeigenfuse, and Levi Keene flew into San Salvador late morning and were shuttled to the Project FIAT guest house by the FIAT driver. Upon arrival, we opened the VFD crate which had been previously shipped to the site, verified that everything had arrived undamaged, and loaded the equipment into the FIAT van for delivery the next day.

__ Results of water testing, June 2014: __


 * Rich, Paolo and the Drexel team suggests extending the wall to protect Valve Box #1:**


 * Bottom of the tank, June 20, 2014:**
 * Rich's comment:**
 * <span style="background-color: #ffffff; color: #222222; font-family: arial,sans-serif;">The floor was not dry. There were some puddles and I think some dry spots. See the photo below. The workers say they could dry it quickly before sealing the bottom. **


 * EPANET model, May-June 2014:**


 * How to prevent water from entering Distribution Valve Box 2:**


 * One could (1) dig a gutter to redirect water down the hill, like they do it on hiking trails and/or (2) cover the valve w/ a bucket to prevent mud from accumulating.**


 * Chlorination of the new tank:**
 * One could place a chlorine tablet directly under the supply pipe, in some kind of an enclosure such as metal basket, suspended from the pipe. The enclosure would be easily accessible from the top of the ladder. The question is whether the tablet will dissolve at sufficient rate. One could place another tablet at the bottom, whole or crushed. Theoretically, if the tablets on the bottom don't dissolve at sufficient rate, the water that leaves the tank right after putting the tablets in is barely chlorinated.**


 * May 29, 2014, ADI quote (coating, glue, mesh), materials $960, labor $ 788+, total 1748+:**

__ May 2014 Implementation/Assessment Trip : May 20-27 (EWB-Philly and EWB-Temple University) __

<span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 8: Tuesday, May 27, '14 //<span style="font-family: Arial,sans-serif; font-size: 9.5pt; line-height: 1.5;">By: Jonathan Campos and Adam Brostow //


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Return trip. Met w/ Miguel in the Morning and explained the operation of confined space blower to dry the tank before painting. He was to install the supply valve box cover, already made, the next day. It has another opening smaller opening for Chilo to open and close the valve w/o lifting the heavy cover. **

<span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 7: Monday, May 26, '14 //<span style="font-family: Arial,sans-serif; font-size: 9.5pt;">By: Jonathan Campos and Adam Brostow //


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Both water (1) distribution testing and (2) water quality testing at the school completed as planned. **


 * (1) Eight (8) new locations were tested for the flow from the new tank into the exiting distribution system, bringing the total number of tested locations to 15.** All locations predetermined on the map receive water**. One house did not have the flow, neither from the old Tank 1, nor from the new tank, possibly for independent reasons. We also also killed two birds w/ one stone by interviewing the households where water testing took place about cooking habits (possible implementation of efficient stoves), talked to doctor de Paz at the clinic, and once again to Morena, the public heath professional.**


 * (2) Water samples were collected from the school, put on ice, and delivered to a laboratory in San Salvador. We ware awaiting the results. Additional surveying was done at the school.**


 * Details:**


 * Doctor de Paz says most parasite infections are amoeba. He thinks this is b/c many people go to the bathroom behind the house, w/o using the the latrine, and the amoebas remain in the soil and then reinfect people, especially children who don't wash their hands. It is possible that the amoebas enter water containers via dirty hands. He says e. coli are not an issue (wouldn't the water/hands got contaminated from fecal matter?) He is going to send us an updated heath assessment. He sees maybe 20-30 people a day; Morena many more.**


 * We examined the tank next to the clinic, supplying water to Las Areneras. They have a special enclosure in the valve box, on the distribution end, where they put 3 chlorine tablets, one every 2 days. When one dissolves, the one above takes its place. This is s'thing we may want to consider for the new tank (retrofit the distribution Valve Box 1? Put chlorine in some kind of enclosure inside of the tank?). The person putting the chlorine said many people use chlorinated water for washing, etc,, but still buy drinking water, $0.75/gallon.**


 * Areneras tank distribution valve box:**


 * Chlorine tablets:**


 * Next we went to see the pumps. The water from the well this time was clear; it was reported to turn yellow from time to time, probably due to pipe corrosion. This time it was clear.**


 * Next we went to the new tank. Chilo put 2 two chlorine tablets into it in the morning. We have to find a way to make sure the tablets dissolve evenly. At 11:30 the pump was started and the tank was filled. We verified that, after it was full, the water entered the old tank via the overfill line.**


 * New tank filling:**


 * Top fill line:**


 * Cracks inside of the new tank:**


 * Distribution Valve Box 1, seems not filled w/ water:**


 * Old tank tie-in to the new distribution system (Valve Box 1', Valve F):**
 * The valve handle was removed to prevent people from tampering with it. The tie-in point uses the old drain line. We may have to add another drain line at a lower level, flush with the actual bottom of the tank. It would make sense to do it form the inside.**


 * Valve K (open), supplying the Daycare Center:**


 * Overflow line between old and new tank, acoustically tested - works fine:**
 * Notice conical sheet metal roof of the old tank, possibly allowing dust to enter the tank.**


 * Next we went to the daycare center. The clinic delivered the Filtron filter, as promised last year. It has to be washed every 8 days.**


 * Then we conducted distribution system tests, starting at 12:30 (it takes about 1.5 h to fill the tank). Chilo opened the valve in Valve Box 2 (Valve O) to distribute water to the north-western part of the village. The box was full of mud and water after the rain. We used a bucket, a shove, and two crowbars to turn the valve. We have to find a way to keep it dry ((a) dig a gutter to make rainwater bypass the box; (b) cover the valve ?):**


 * After testing the north-western part of the village, we tested the area west of the soccer field, supplied by a separate pipe. Here are all new results:**
 * Point..............8.....9....10.11..12..13...14....15**
 * avg rate L/min 22.7 5.5 8.1 8.2 8.2 2.1 12.4 15.1**


 * Water from the new tank at one of the houses at the end of the distribution system:**


 * Map w/ the second set of test points:**


 * Distribution valve box supplying water to north-western part of the village (Valve N):**


 * It would be interesting to run the test at some of the same points w/ the** old system **(tanks at high altitude, new tank isolated), to see the difference. One would expect higher water flow rates at higher liquid head but the net amount of water supplied should be similar.**


 * We interviewed Vincete's (the pump operator) wife and 6 owners of houses where we tested water rate about their use of fuel. All 7 households use BOTH gas and wood, wood to cook food that takes more time such as beans and tortilla, gas for making coffee or boiling eggs. Most households had gas inside of the house and wood fireplace outside in a semi-open enclosure. A bundle of wood cost $20/bundle.**


 * The wood stove:**


 * One of the households had a large open water cistern. The owner said the mosquitoes are not an issue as he keeps small larvae-eating fish in the tank.**


 * Talked to Morena (the public health person). She says 50% of households use gas only, 20% wood and gas (all 7 we interviewed), and 30% wood only. Wood is cheaper and good for long cooking. Smoke is not a major issue as the wooden fireplaces are usually outside, but the cost is. Morena is interested in efficient stoves.**

<span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 6: Sunday, May 25, '14 //<span style="font-family: Arial,sans-serif; font-size: 9.5pt;">By: Jonathan Campos and Adam Brostow //


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">We went on a trip on Ruta de Flores. There wasn't much we could do at the village on a Sunday. **

<span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Day 5: Saturday, May 24, '14 //<span style="font-family: Arial,sans-serif; font-size: 9.5pt; line-height: 1.5;">By: Jonathan Campos and Adam Brostow //


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Flow testing: Adam, Dr. Ryan, and Jonathan confirmed our meeting with Cecilio on Monday to test the water flow in the northwest sector. We were also able to convince Cecilio to test the very southwest end afterwards. **


 * The new supply valve box, needs to be covered:**


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Sediment and piping material: The sediment seems to be non-issue because the colored water found in the daycare and community center was caused by lack of cleaning the old blue tank. There is no flush outlet in the old tank at floor level as with the other tanks. It is used for cleaning the tanks which is done each month. We also asked about the pipe materials, the only galvanized pipes used in the system are in the well. They need to be replaced every 2 years according to Miguel—maybe we can discuss replacing this pipe with another material. **


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Plan for 5/26: Stop by clinic for health related questions in the morning. Look at how chlorine is added to Tank 1. Observe pump operation and new tank filling. Perform flow testing. **


 * <span style="font-family: Arial,sans-serif; font-size: 9.5pt;">Other: We picked up sample vials from LECC for testing the three tanks in the school for Legionella, several bacterias, and sulfate--will attach quote. The Temple group surveyed the school and is near completion. **

<span style="font-family: Arial,Helvetica,sans-serif;">Day 4: Friday, May 23, '14 //<span style="font-family: Arial,Helvetica,sans-serif;">By: Jonathan Campos //


 * <span style="font-family: Arial,Helvetica,sans-serif;">Conversation with Cecilio: Cecilio agreed to do New Tank water flow testing in the northwest Monday. He did not want to do it Saturday or Sunday because the schedule is to normally fill the northwest personal tanks on Mondays. We were unable to do any testing at the very southwest end as the new tank was completely emptied this morning. There was[[file:new tank after emptied.JPG| some sediment left over in the tank]], but it did not seem excessively bad. Note the [[file:2014-05-22 12.42.50.jpg|picture of filling the tank yesterday]]. **


 * <span style="font-family: Arial,Helvetica,sans-serif;">Conversation with Morena (nurse) and Cecilio: She was upset she was not invited to the ADESCO meeting, but she still met with us fortunately. We were told there are 700 viviendas (homes) and we got population data—there are 2556 according to data taken. We were told there are about 20 cases/month of water related bacterial and parasite infections. She said out of 23 current pregnant women, 18 have urinary tract infection, 3 had premature births, and 1 miscarriage. She believes some of these infections may be related to impure water. The government provides anti-parasitic medicine, influenza vaccine (Vaxgrip), and pneumococcal polysaccharide conjugate vaccine. Morena has a chlorine test kit, ortotolidino, where she will add a color indicator to a water sample and depending on the color, you can find out if it has no, adequate, or too much chlorine. She tested the water from the sink in her office and there was no indication of any chlorine. She then became upset with Chilo for not adding chlorine despite water treatment training the government provided 5 years ago—she said she’ll try to get re-training in the near future. Chilo claimed he adds two tablets to Tank 1 and 3 each time the tanks are filled (Tank 2 is spring fed and thought to be non-issue). We then went to the home where he keeps the chlorine. It was manufactured in 2008 and is 1/4th full—they’ve had it since 2009. **


 * <span style="font-family: Arial,Helvetica,sans-serif;">Chlorine treatment: It is doubtful the chlorine is used as the bucket is quite heavy and the tanks very far—we’ll have to ask him how he does it. Dr. Ryan found a source indicating the tablets last only 2 years and the storage environment is not the best. The [[file:chlorine 2.JPG|bucket ]]has an inner lid that is screwed down and this lid was brittle. In addition, the tablets were in individual plastic packets, but they have practically disintegrated into [[file:chlorine 2.JPG|flakes]]. We’ll also need to discuss how to best treat the water and that entails where (at the tanks or at the pump) and how (if someone should sample the water when adding the chlorine using a color test kit). **


 * <span style="font-family: Arial,Helvetica,sans-serif;">Tomorrow’s plan: We plan to review what we found out with Morena and Adam. We asked about cooking hot food and were told the majority of people use gas for cooking. However, she also told us many use wood cooking for beans—this is something we’ll need to find out more about. She has seen that some get sick from the smoke. We also hope to ask Chilo about the sediment, how much sediment they typically get in the tanks and the frequency, where he sees it/gets complaints, and if he’s always seen it. We also plan to ask him where there are iron and galvanized pipes and ask him specifically about the material of the pipe he replaced in October that Lynette observed on a prior trip with heavy rusting. **

Day 3: Thursday, May 22, '14 //By: Jonathan Campos//


 * Community partners: We met with the ADESCO board, Cecilio (Chilo), and Miguel. We took phone numbers for ADESCO so that we can advise them when the team is coming to install the VFD. The president asked that we make sure to do this. You can get their phone numbers from me. The group was okay with us doing flow tests in homes, adjusting the valves, and filling up the new tank. I asked about pumping energy costs, for the 901B, and they have said they still spend $1350/month for ~86hrs of pumping as captured by Adam in the MOU.**


 * Flow testing: Chilo filled the new tank via the pump--the water in the tank was orange, but we don't know if it was orange from the pump or from residual sediment we saw yesterday. After filling it, with Tank 1 isolated from the system, J-167 was closed so that water from the new tank stopped there. We tested the rates at 7 points indicated on the map. The path of the water is [[file:Southwest end flow tests.jpg|shown in green in the picture with rates numbered 1-7 listed below]]--each value is the average from 3 tests. We initially wanted to have all the valves open on Tramo 6 and Calle Principal so as to measure if the new tank has enough head for flow through out the system, but we were told the water would be lost and too low in pressure. The way ADESCO manages water distribution is having Chilo turn the valves for different sectors each day. Families will leave their taps open, so if Chilo does not shut the water off for sectors with filled personal tanks, water for other personal tanks is lost. Chilo cut-off the water at the interesection of Tramo 6 and 6a because he said if it was opened, Tramo 11 and Tramo 6a would not get water. However, when Tramo 11 and 6a fill their personal tanks, Chilo will redirect the water to the west end of Tramo 6--he says we can expect similar rates there. Note that the rate out of point 4 is ~1/5 of the other rates. Chilo says if needed he'll close valves downstream to increase pressure at point 4. We didn't have time to test other points as a downpour started. We would like to confirm that the west end of Tramo 6 has similar rates to 11 and 6a. Tomorrow we will ask Chilo if he can do more testing with us on Saturday or Sunday with Adam--we need to test the northwestern sector. There was resistance in doing the testing today as that sector had been filled already.**


 * Rates (L/min)**
 * 1: 15.4, 2: 11.5, 3: 10.9,**
 * 4: 1.7, 5: 9, 6: 13, 7: 27**


 * By: Adam Brostow**


 * Looks like good progress. I makes sense to take average readings; i forgot to mention it. Now we want to do points F-1, and F-2, J-145, J-168 on the other branch. We may want to close the valve at J-1 for the northern branch.**


 * I talked to Brian. He is happy with the progress. He suggests using confined space blower to dry the tank before painting (if we can get it):**

 * Hope to see you tomorrow.**

Day 2: Wednesday, May 21, '14 //By: Adam Brostow//


 * In addition to new tasks, the team will try to test the water distribution system and/or supervise the coating of the new tank, both tasks crucial to the project's success. Completing both tasks is probably not realistic as (a) we don't know how long the coating will take, including cleaning; (b) if the distribution system is to be tested first, the tank has to be dried and cleaned before coating.**


 * If ADI does not come up w/ the labor, materials, and completion time quote on time i would test the distribution system first. We have to fill the new tank first. While doing this, we want to test the overflow line to the old tank to make sure both can be filled directly from the supply line (not from Tank 1 at high elevation). Then we would test the distribution system. We will need Chilo's help. Once this is done, we would dry the new tank and, preferably, get ADI started on coating/painting task.**


 * We want to make sure the supply valve box is covered.**


 * AAB**


 * By: Jonathan Campos**


 * Community partners: Today we went to Las Delicias and met with Cecilia, the new ADESCO Treasurer and jewelry vendor. We also met Sergio, the ADESCO secretary.**


 * New Tank Sediment: Sergio and Miguel took us to the new tank. They pointed out there is quite a bit of sediment in both tanks and we were told some are getting their clothes stained red from the sediment. We were told when the new tank was filled, after emptying it, there was a cm thickness of sediment on the rebar ladder on the inside of the tank. It seems like we may need sediment filters and/or may need to consider replacing the iron pipes if possible (Sergio also said some of the pipes were galvanized)--we'll have to figure the cost and sustainability of both. The CO2 in the water may be reacting with the iron. Dr. Ryan had some correspondence with Dr Dina Lopez of Ohio University indicating the presence of CO2. Walt emailed the group about this Feb 15th. Below are pictures of pipes that feed into the bottom of the tank and the inside new tank ladder. The underwater pipe shows sediment and the other shows some torn plastic embedded in the concrete.**


 * [[file:new tank feed pipe 1.jpg|feed pipe]], [[file:new tank feed pipe 2.jpg|feed pipe 2]], [[file:inside new tank ladder.jpg|ladder]]**


 * New Tank Sealing: There are indeed cracks on the inside, '[[file:new tank inside crack.jpg|new tank inside crack]]' is a close-up of one with sediment inside. As discovered earlier, the Sika Flex we provided was not used for sealing the tank as promised. We were promised a quote including labor and an assessment by an 8yr technician for sealing the tank. There was a delay because there was concern with the safety of their workers as the tank has been spray painted. Lynette reassured the Aditivos rep I spoke with, Ernesto, that the area is safe as Sister Gloria has a strong, positive relationship with the community.**


 * Distribution Testing: Sergio was kind enough to take us to the valve boxes we'll need to access for flow testing to confirm that the head from the new tank is enough to supply the 280 homes on the west side of Las Delicias--this is important for energy savings. The west side elevation is lower than the new tank elevation, so it should allow for gravity fed water. We'll need to shut off the old distribution valves, in valve boxes J-167, J-1, and valve E, so that the head from the other tanks does not skew the results. J-1 is buried, so we'll need to bring a shovel to dig out the dirt. We'll have to empty the pipes with existing water from the other tanks as well--we'll need to confirm this is okay with the community and plan to meet with ADESCO tomorrow morning with Miguel and Chilo to discuss what we want to do and any other issues that may have come up. According to Miguel, the distribution system is getting water to everyone more frequently than before at a faster rate--rates to be confirmed. We were told some pipes burst, so we'll try to get more information on that.**


 * Other observations: There's quite a bit of trash and there doesn't seem to be pick-up service. Many of the school [[file:asbestos roofing.jpg|roofs are made of an asbestos/concrete compound]], here's a link about it:**

Day 1: Tuesday, May 20, '14 //By: Jonathan Campos//


 * Arrival: We arrived in El Salvador fine courtesy of some of Sister Gloria's partners.**


 * Customs: We had some trouble going through customs with some of the equipment we brought. Our mistake was to record its value in the merchandise section--there's nowhere to claim the value of equipment you are bringing and returning with. We were correct in noting that it was professional equipment, however. Once they saw that the equipment had a tag on it saying Temple University with an inventory number and Dr. Ryan's ID, they were fine with us bringing it. In the future, it may smooth things out if we bring letters in Spanish that whatever equipment we bring is property of wherever we're bringing it from and that it will return with us at the end of the trip. We did bring a letter from Project FIAT, but it was not sufficient.**


 * Cultural: A video was shown on Oscar Romero, a Salvadorean hero and Arch Bishop devoted to helping the poor, giving us an idea of El Salvador's historical background.**


 * Partners: There are 29 students from Williamson Trade School out of Media, PA--a group of theirs helped dig trenches for the distribution system along with several other items with Adam in May last year, they also built some homes. They have built a retaining wall, put glass blinds in the community center, and I believe they've built some homes.**

 * __ Implementation Trip : January 11-18, 2014 (Walt Walker, Paolo Belfiore, Rob Ryan, EWB-Temple) __**


 * Day 8 (Saturday, 1/18) **

Heading home today! There was great progress made over the past week. We'll be sharing in full detail at the January 23 chapter meeting.




 * Day 7 (Friday, 1/17) **

To start the day off, we review the existing trench work, and great progress has been made. The trenching has been completed right before the junction point at the main road. The supply piping may be installed within the next two weeks. We discussed the gameplan for the proposed valve locations with Miguel (and he will follow up with ADESCO for agreement): the proposed area shown in the zoom of the drawing below, and adding another one somewhere in the area where the yellow icon is placed:



We split into two teams for our last day at the site. Four team members visited the school and health clinic, and had a lengthy discussion on the current situation and future work to be done. A report summarizing this meeting will be provided shortly.

The other two team members (along with two FIAT volunteers) worked with Don Israel (who btw, also goes by "Don Ira") to begin physically constructing the new valve box by the intermediate tanks. After discussion, we agreed it was not necessary to include the check valve in the box. Miguel and Don Ira will finish this next week.


 * Day 6 (Thursday, 1/16)**

This was observed a few days ago, but should be mentioned: There is a valve box for the new distribution line at the intersection of the Community Center road and the top of the inclined concrete road, as identified in the drawing next to the photo below:


 * //Wednesday, 1/15://** //Updated Valve Placement Drawing (by Adam Browstow)://

// The drawing now shows the newly installed check valve that prevents backflow to the new tank. Valve I was moved to the valve box to isolate system around the soccer field supplied by Tank 1. Valve J may be added in the future to still be able to supply the area around the soccer field from the new tank. Existing valve K supplies the community center. The new valve box tying in to the existing distribution is now shown. Valves L isolates the new distribution system from the old one. Valves M is on the exiting distribution system. The two are in "dog houses." When valve L is closed the system can be operated as before (a fallback position). //


 * Day 5 (Wednesday, 1/15)**

We completed the report summarizing the 1/12 meeting with ADESCO, which you can view here :

A 2-inch check/backflow valve was added to the distribution line by the new tank. The other valves were resealed: Samples for water quality testing were performed at seven locations in Las Delicias: (1) The well pump cistern; (2) The well pump cleanout/flush opening; (3) The health clinic; (4) The school; (5-7) Tanks 1-3; and (8) The outside sink on the porch of the daycare center. Test strips were used to test and obtain immediate results for most parameter, with the exception of sulfites and bacteria, which was submitted to the local lab for testing (results should come in a week). You can view a full results list of the parameters we tested and obtained immediate results for here: In summary, notable results were high numbers of conductivity, TDS, alkalinity, and hardness for all sampling points. The well pump cleanout/flush opening had an unusually high Iron content, which leads us to believe that Lynette's report of water discoloration from a few weeks ago is probably from the pipe interior being rusty. Below are some photos from the day's water sampling collection:



We also visited the school for sampling, and took photos of their multiple tanks:

Also, we prepared the custom valve box for the two distribution valves at the junction point mentioned in Day 4. First we mixed cement and then poured a mini slab under the valves. The "doghouse" manhole (an 8-inch SDR 17 pipe which we saw cut an opening the width of the pipe) was then fitted over the valve and onto the wet cement. Btw, SDR 17 is much thicker than the standard SDR 26 used for gravity water or sewer lines; so this should hold up to traffic loads. Once the cement dries, we will fill the trench with stone up to an inch above the pipe, then top off the remaining opening with the existing soil backfill.




 * Day 4 (Tuesday, 1/14)**

We called the city laboratory and picked up 10 sampling bottles. Water quality testing of select points in the community (including the supply well, school, and health clinic) will be performed on Day 5 (Wednesday).

Upon arrival in Las Delicias, there were again at least 8-10 volunteer workers digging trenches, with ADESCO (Sergio) present. Looks like our discussion on Sunday helped. The workers are approaching the intersection of the main entrance road. Don Israel and Chilo worked on the new/existing water distribution connection. We consulted with them on the proposed setup Monday afternoon. Since the existing distributoin line was found to be closer to the middle of the road, we had to install a connecting pipe and tees to the new distribution line from the Intermediate Tanks. We plan to keep the valve shown in the bottom left of the photo closed, as part of our proposal to use the additional capacity that it would provide Tank #1 to service the homes south of the soccer field (as mentioned at the end of the "Day 3" entry).



Since the connection is almost in the middle of the road, to alleviate concerns on vehicles potentially crushing the valves, we proposed using the SDR 17 plastic pipe (thicker than standard SDR 26 pipe), and custom manufacturing a "Doghouse" valve box directly over the two valves (see below). Stone fill will surround the pipes and valves to add additional support (then the dirt fill will top off the trench).



The team spent most of the day demolishing the intermediate tank valve box because:
 * 1) The floor needed to be deeper;
 * 2) The box needed to be longer; it will extend closer to the new tank to ensure that the 2-inch distribution lines (the larger ones) have room for servicing (since the box wasn't originally centered on the cross connection)
 * 3) A backflow valve will eventually be added on the side of the distribution line closer to the new tank, to ensure there are no issues with the cross connection of supply and distribution lines. Miguel agreed with this setup, and we purchased additional valves in the morning.

What you see below are the new limits of the new box we will construct (it essentially just a foot or so longer, going towards the new tank):

Tomorrow, we will split into teams and: (1) perform water quality tests at selected areas; (2) oversee the backfill of the open trenches.


 * Day 3 (Monday, 1/13)**

The ADESCO meeting was longer than expected, so we continued to walk the water system and visit key items: all three main water tanks, the source supply (well), junction points along the main road of construction. The trench work has resumed:





We met with Chilo and Don Israel (the mason), to confirm our desired locations of valves and supply/distribution tie-in points along the main construction road.

The trench digging for the distribution line tie-in began (and to confirm existing water line locations) began; our team, and FIAT volunteers contributed in the digging.

Upon return to the guesthouse in the evening, the travel team reviewed the setup of Adam's proposed water line & valve setup (**see Adam's January 13 entry below**), and the newly constructed valve box by the intermediate tanks. We had concerns on whether the new tank and the old blue tank would be capable of serving <span style="background: none !important; border-image: none !important !important; border: currentColor !important; display: inline-block !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; text-transform: uppercase !important; vertical-align: baseline !important; width: auto !important;"> on the other side of the soccer field, especially if the water level in the blue tank was low. It was agreed that alterations to the proposed setup would be made:* Proposed Valve "I" would be moved into the intermediate tank valve box, onto the line entering the existing tank; therefore, there will be four valves at the intersection one for each line, ("A" and "I" along the supply line to the blue tank, "B" and "C" on the distribution line of the new tank)* Valves "A" and "I" will be closed. Tanque #1 will serve the houses south of the soccer field.* At the junction of the new and existing distribution line, a valve would be installed on the existing line before reaching the tee, and would be shut off since the double intermediate tanks should have sufficient flow to service the bottom half of the community currently having water service issues. Therefore, Tanque #1 should have sufficient capacity to service the houses south of the soccer field.


 * Day 2 (Sunday, 1/12)**

We began walking the community to: (1) give the EWB-Temple team an overview of the entire water system; and (2) to see the existing construction work that's been done. EWB-Philly and Miguel met with Hilda and Sergio of ADESCO (a group, in our interpretation, is the community's version of a city council) at the community center, around 3pm and the meeting lasted until 4:45pm. We discussed our expectations of ADESCO being more involved our construction project (getting volunteer worker contributions), and generally a more frequent presence in the community. A full report of this meeting to come from Paolo soon. Before the meeting, we visited the newly constructed valve box by the existing and new tanks:

Upon first look and review, we were confused as to the setup and direction of flows. Miguel also expressed is frustration at the small distance between the bottom of the pipe and the valve box floor. I agreed, and proposed that the floor needs to be deeper. The fittings of the 2-inch supply lines were also loose, and leaking. I emailed all the active members of the project of these concerns Sunday night, and Adam responded with his clarification and proposal of the water line & valve setup, in the January 13 post shown below. That drawing will be referenced again, since Adam's lettering system was helpful to understand and reference.


 * Day 1 (Saturday, 1/11)**

Arrival in San Salvador. Upon arrival to the FIAT guesthouse, reviewing scope of work for the week while in El Salvador.

 * __ May '13 update (Adam): __**

Saturday (Day 6)

The rotary guy didn't come so i'm stuck at the guesthouse.

I talked to Brian. Here are some option concerning connecting the old tank with the new distribution system. We probably want to make both the shutoff and the check valves available. We can put them both in a new small valve box or the one we just built. To avoid a valve box, we can arrange them both vertically above grade. Then we will have to either (a) remove the handle of the shutoff valve or (b) build some kind of an enclosure around them.

We have to think about whether we want a valve isolating the line from Tank 1. If we don't will some of the water still come from Tank 1 when we're draining the new tank?

We thought of putting the 4'' supply line inside of the valve box to keep the two lines together. Miguel thinks he can put it outside and still bring them together on the other side. This leaves more room to work inside of the box.

We have to think about how to prevent trucks going over the new valve box. According to drawing we put no rebar in the wall. Some kind of a fence or sign would be useful. Miguel suggests a concrete speed bump (tope).

I gave Miguel the new drawings. He says he can finish the box himself.

Friday (Day 5)

Today we installed fittings and elbows for 2 and 4 piping to/from the new tank. We also bent the 4'' pipe (using heat) to make it fit the trench and the new valve box:

Fitting 4'' pipe by heating and cooling (with water):

We also installed the two valves on the new distribution piping and connected it to the piping around soccer field with an 4-way fitting, all inside the **new valve box**:

We still have to figure out if we can fit the 4'' pipe inside of the valve. It fits but it will be difficult to fix the 1/2 piping in such small space (any comments?). Ideally, we want to run the 2 and 4 pipes side by side. The other option are (a) to put the 4'' outside the box - then the two lines have to brought back together; (b) to enlarge the box - Miguel can do it easily. Tomorrow i'm going to take a closer look at how much space we have.

As far as the tie-in points, what needs to be done is a tie-in from the old tank to the new distribution line and a tie-in/valve box on 4'' supply line.

T ie-in from the old tank to the new distribution line has two options. One is a vertical shutoff valve above ground, and horizontal check valve:



That way we can avoid another valve box. However, unauthorized people can play with the valve. We can remove the lever and Chilo can carry put it back on when turning a valve. Another option is to put the shutoff valve in another small valve box (any comments?).

As far as the tie-in/valve box on 4'' supply line, we will probably put the check valve and the shutoff valve near the main street, as originally planned. Theoretically, we could squeeze the shutoff valve into the new valve box next to the tank but, regardless of where the check valve is located, all the piping would see high pressure when the pump is pumping to tanks 1/3.

Tomorrow i'm going to look at everything again with a guy from the Rotary.

Adam

Thursday (Day 4)

We built part of the wall around the valve box ( One can see the 4'' elbow in the background):



We also completely took apart piping around valves supplied by the Rotary in order to reuse them. Originally, we wanted to do the piping first and then build the enclosure but, in order to reuse the valves, we had to buy more fittings.

We may not install the line from the old tank to the new distribution system. We may want to actually install the shutoff valve (just in case), possibly on a vertical run of the pipe above ground (any comments?), followed by buried check valve (we salvaged it) on the horizontal run, and tie-in point to the existing system (more or less like on the original drawing and sketch). We have most of the fittings. For one thing, we cannot tie in to the system containing water (between the two valves on the blue line on the sketch below, and the the old tank until it's drained. Here is a sketch:

I talked to people at the daycare center. They need a water filter for their Filtron bucket (they use chlorine). I went to the clinic to talk to volunteers. They will provide filter for daycare. They say water from the well gets yellow. Local people said it makes them sick. On the way back we tested the pump:

The yellow water comes off in slugs (it is clear for a while then it turns yellow, then clear again). It is probably iron not bacteria. We should do the analysis.

I printed, signed, and submitted Paolo's letter to be co-signed by ADESCO and sent to the Mayor's office.

Tomorrow we hope to finish the box and connect the piping.

Wednesday (Day 3)

Today we poured concrete slab for valve box 1/2:

We also obtained on/off and check valves we're going to reuse:

We also bought all PVC fittings (Ts, X, elbows, 45-deg. and 90-deg. reducers) and glue.

Rich's check list w/ answers: 1 - the old tank is connected to both the clinic distribution line and the new distribution line

Yes, the line to daycare is left unchanged, w/ new connection to the new distribution line.

2 - both tanks are connected to new distribution line with check valve to prevent back flow into old (lower full height) tank

Yes, check valve on the line from the old tank to prevent back-flow from the new tank (higher level).

3 - new distribution line connects (with shutoff valve?) to old distribution line to supply houses near soccer field

Yes, it will connect w/ an X-connector to the existing line. The two shutoff valves on the new line will allow running the system as before.

4 - have shut off valves to stop flow from either tank and to the old distribution system

The two valve on the eastern side of the road should prevent flow to the old distribution system (see updated drawing below). New tank will have a dedicated valve. Old tank may not need one - will talk to Chilo.

5 - (optional) maintain option to fill old tank from existing lines from old tank - but be careful not to create a situation where new tank could overflow old tank

See above.

Adam

Tuesday (Day 2)

We excavated the area around the old valve box and removed the old brick enclosure (managed to brake the pipe - it got fixed):

The on/off valve close to the new tank is actually 3''. To it in the new valve box we will have to add two 3 X 2'' reducers. The existing trench is dug in such a manner that we may need two 45-degree elbows (for each pipe) to connect to the existing distribution line (please comment). This will actually connect to the distribution line at the right angle, which may be an advantage.

Here is a proposed simplification that saves a valve (so we can reuse the two existing valves): We can directly connect the old tank to the new distribution line (just a check valve, no additional on/off valve). What do you think?

We obtained a quote for paint for an inside of the new tank (Macropoxy 646, 2 gal. for $190, covers 30-45 m2, safe for drinking water).

Tomorrow we will do the concrete foundation for the valve box.

We met with Daniel Rivera from the Rotary. He is on board with the changes and said he could help get the jackhammer and compressor for free.

Monday (Day 1)

I went to Las Delicias with a group of volunteers from Williamson College. The Rotary Club did the following work: (a) Installed on/off valve at the distribution outlet of the new tank: (b) dug up a trench connecting the outlet of the new tank w/ the old distribution valve box at the old tank: (c) installed piping piping w/ on/off valve and check valve in parallel (connected to nothing, leading to the line to the daycare center) next to the old tank:



Old box next to the old tank: It seems like the Rotary followed the old drawings pretty faithfully. We will have to rearrange it. We will: (a) Disassemble the old valve box; (b) Enlarge it to accommodate 3 valve using 1 X 1.5 X 1 m deep enclosure made w/ 15-cm wide concrete blocks (we are arranging for the blocks, sand, and cement); (c) Move the on/off valve from the new tank to the new valve box and and another on/off valve (as on the new drawing); (d) For the second valve box (above ground) arrange on/off valve in series (not parallel) and connect them to the existing old tank purge line (with new purge line added below; the purge line is well above the bottom) and the new distribution line. (e) install PVC in a ditch between the new tank and the valve box and cover it up (hopefully, this week).

The crack on the new tank is only on the outside (good news) and is less than 1 mm wide so it obviously does not penetrate to the inside through the mortar and the inner wall. There is no crack on the inside. Bill (builder-volunteer) thinks is this is not an issue.

I talked to Chilo (valvulero) and Don Rene. We will probably have to install another on/off valve to isolate the Tank 1 distribution system. If the new tank doesn't have enough head to provide water to houses south of the soccer field we can still use water from Tank 1.

For the concrete section we can rent a concrete saw for $60/day. Bill says we can do the concrete in 1-2 days. If, at any stage, we will cut concrete, we will have to finish the job. We need a saw (to maintain straight line) regardless of if we do the rest w/ sledge hammers or jackhammer (i called the outfit suggested by Elsy).

Tomorrow at 10:00 i'll talk to Daniel Rivera from the Rotary.

Adam

The tank roof hatch and interior ladder has been installed. The valve box outside the tank will be installed this week.
 * __ October Update: __**



The day after the concrete pour, additional work still being done to the tank. Photos below. I'm expecting to receive some better roof photos from Daniel.
 * __ Walt, Barbara, and Joe's trip (August 8-14) __**
 * Day 7 (Tuesday, 8/14) - by Walt**







As promised, Daniel did arrive, along with the concrete mixer truck around noon. Joe and I went to Las Delicias, and Barbara went around San Salvador getting VFD info from vendors. Below is a commentary & summary of all events and updates as of Monday. Please respond to any items in the email chain via it's corresponding number. I will subsequently add/update pertinent info or responses for that item in ** blue bold ** font.
 * Day 6 (Monday, 8/13) - by Walt**

1) Sika flex (sealing to prevent tank leakage) has been applied to the interior of the tank.

2) Sister Gloria will be back in El Salvador October 13-27 (at which time we'd be more than welcome to stay), then December until most likely Summer 2013. It might be possible to visit outside of the October timeframe when she isn't there, but major logistics would need to be worked out with issues such as availability of her drivers and such.

3) Daniel and I agreed to have the valve box located in the general area of where the black trash bag is shown on the ground (lower middle). We opened up the existing valve box (valve is broken, btw) located in the elevated slab (upper right corner) to see the size of the pipe. It appears to be 2 inches. **So in the valve box, will the valve for the piping from the new tank will be 4-inch, while all valves for the existing tank piping be 2-inch? Please confirm**. (Also see Dwg. G-01 of the engineering drawings to view the layout of the valve box).



4) Daniel was informed of the issues of the grading surrounding the gutter of the tank base being too high around certain areas, like the area shown below (first pic). He's aware that some of the soil needs to be graded down. If he has some extra concrete, he might add a few inches on the gutter wall as well. The gutter outlet will lead towards the road (second pic). The tank drain pipe will be on the side of the soccer field (third pic)





5) They hope to complete the access hatch, roof vent pipe (w/ screen), and installation of the equalizer pipe this week. Looking at Dwg No. "Tank Details - 3", it appears that pipe will be 4-inch galvanized steel. Please confirm.

6) In an adjacent building (the activity house where Sister Gloria's people watch the kids), they have stored 400m (1312 feet) each of 4-inch and 2-inch plastic pipe. **Where is 2-inch pipe planning to be used? Please confirm.** 4 is the supply line, 2 is distribution; they will be buried side by side (**Adam**).

7) Budget: Daniel says he is currently at ~$14,200 spent in Rotary funds. This amount also includes Miguel's compensation (~$300) and Sister Gloria's repayment ($522), but Gloria has not yet been compensated. I'll remind Daniel to do so. He thinks the remaining $800 should be able to cover the cost for the valve box and valves (if the valves for the line from the existing tank are 2-inch; if larger, might be a little more)

8) We took dimensions of the concrete section of the road leading up to the community: 17' wide x 252' long. Rene was not there to answer our question of whether the Mayor's office would at least trench the section of the road that is dirt, but I asked Daniel to look into that. In any case, we should consider doing a cost analysis to see if we can afford to fund paying a contractor to do the work to dig up the concrete. While an option, I don't feel completely comfortable with supply/distribution pipe above ground, even if it was steel. The picture shows right side of the road. I think the left side is level (or is it?) if we were to bypass the concrete on the private land (**Adam**).

9) I made an attempt to use my phone as a GPS device for taking points along the path where the new distribution piping would be installed. Sometime this week, I'll put the points into Google Earth to see if it actually worked.

10) Again, Rene was not at the site to answer my question of who performs electrical maintenance services for the pump. Daniel said he would assist looking into this, and whether or not it's a particular company that does it. I will email him a summary of the follow-up items discussed between me, him, and Joe. **Adam**, perhaps you can reach out to Rene once more.

I emailed the secretary of ADESCO but got no answer; we can also use Paolo's contact or i can call eng. Chinchilla - talked to him before (**Adam**).

11) VFD Updates (//by Barbara, who visited the vendors today//) <span style="font-family: Arial,Helvetica,sans-serif;">__Vendor #1 - Movaria__: I went there with Sister Gloria. Met with Mark Dieter Waechtler, the one who wrote the quote. He is fluent in English, and I was able to describe the overall project and our needs for the VFD, its controls and the timers/level control system. I gave him a copy of the new 525 with the two drawings and the detailed list of components. He said **his company can supply everything**, build the panel and install it. He can get all the work done in 15 days. It was left that he will email us a detailed quote, probably to Brian, Adam and me (so at least one of us should be hearing from him soon. My overall impression was very good - essentially no language barrier and quick comprehension of the technical details.

<span style="font-family: Arial,Helvetica,sans-serif;">__Vendor #2 - Antech__: Anner Chavez came to the guesthouse. Sister Gloria acted as the interpreter. I gave him the 525 report. He asked some technical questions that I did not have the answers to. We tried to call Adam and Brian, but it was 5:00 and neither picked up. So it was left that someone will call him and discuss our needs in more detail and answer his questions, after which he will give us a detailed quote. His company **can also do everything - supply, build, install**. Adam, because you are fluent in Spanish and know the details, would you call Chavez?

<span style="font-family: Arial,Helvetica,sans-serif;">Anner Chavez emailed me w/ a list of questions and comments; i will follow up (**Adam**).

12) Pouring of the concrete for the roof slab began around 1pm. Joe and I had to leave with the group an hour earlier than usual (2pm) because the group visited a Romero memorial site. I asked Daniel to take pictures of the completed slab. As a backup if he doesn't immediately respond, I asked one of the FIAT volunteers in our <span style="background: none !important; border-image: none !important !important; border: currentColor !important; display: inline-block !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; text-transform: uppercase !important; vertical-align: baseline !important; width: auto !important;"> to take pictures of the roof Tuesday, since our flight leaves early that day. When I receive those photos, I will share them here and in an email. Below are some pics as the concrete mix was being poured and leveled.



13) Eventually, we need to look into repairing the existing tank. Lots of openings and wearing where the roof joins the tank





No work was done on the weekend. The construction crew was waiting on the concrete for the roof slab to arrive in the weekend. We waited until Monday to visit the VFD vendors in case we obtained any pertinent electrical info from Rene or Daniel**.**
 * Day 4 & 5 (Saturday & Sunday, 8/11-12)**

Progress discusssion between Walt and Adam
 * Day 3 (Friday, 8/10)**

1) Trenching

As Walt pointed out, the issue is not availability of machinery (jack hammers and concrete cutters) but the cost.

Here are possible options, assuming we cannot touch the concrete section: a) All piping above ground b) Buried piping along the dirt road (from Calle Principal to the concrete section; from concrete section to the tanks), above ground over the concrete section c) Buried piping everywhere, off the road through private property along the concrete section d) Altogether different route for buried piping.

The above ground section can later be **retrofitted** with buried pipe when funds becoma available.

Action items: i) We want to find out if Mayor's office will **still** do the trenching for the dirt sections without concrete (ask Don Rene of ADESCO, Ing. Chinchilla, Daniel, whoever) ii) We want to ask how much cutting the concrete would cost.

As Walt pointed out, we may want to use galvanized steel (instead of plastic) for above-ground section for durability. Regardless, above ground piping is a possibility; this is routinely done in Mexico. The issues are weather exposure, theft, and vandalism. The advantage is it can be fixed without digging (leaks, etc.).

2) Valve box. Discuss location with Daniel on monday.

3) Concrete pouring for the roof, monday.

4) VFD, talk to venors, monday.

5) Money. Let's make sure Sister Gloria got/gets her money back. Discuss budget with Daniel, solicit weekly expense report.

6) What company did electrical panel repairs in the village? I sent some emails but got no answers (AB).

7) Sika flex. Let's make sure they will apply it/have applied it where needed.

8) Connecting pipe beween the two tanks. The new tank has an opening for it. Let's make sure they connect it correcty to the old tank,

9) Elevations. Elevation difference between the new tank and sections of the village where water is to be distributed, if time permits (will require a measurement of the known elevation of the new tank and of another elevation; the absolute value does not have to be accurate).

10) Photos (added by Walt) //View of the tank work done to date.//

//Additional rebar reinforcement added to the roof slab.//

//Opening for the equalization pipe. A penetration hole in the existing tank has not yet been made//.

Externally, the tank looks pretty much the same (some additional work was done to the outer base) as the photos Daniel sent on August 1. Speaking of which, he was not at the site today, but was told by Miguel that he will arrive tomorrow. . Other comments:
 * Day 2 (Thursday, 8/9)**

1 Miguel says he expects the concrete for the roof to arrive on Monday (but I'm skeptical). 2 Barbara spoke with Rene from ADESCO, and it was her understanding from Rene that the Mayor's Office will no longer dig up the concrete to install the new supply line due to costs; but they are willing to install the supply line above ground.

Are they willing to dig the trenching everyplace else (except the concrete section)? We could have the pipe above ground just for the concrete part (95 paces, ~80 m). It's routinely done in Mexico. Brian, any comments? I know this wasn't our intention. Or could we hire someone else to do the concrete? I was told by eng. Chinchilla they will get the cutters/jack hammer, now the're paddling back. AB.

3 Please clarify the location of the valve box. See attached 3 photos.

Daniel and i discussed the place to the tight of pieces of wood on the first photo.

However, Las Delicias Project Drawing (on the wki) shows it behind the old tank, near the concrete structure (Page 1, Detail 2):

http://ewbelsalvador.wikispaces.com/

You can discuss it w/ Daniel. AB

AB.

4 No time frame on when the valve box will be installed. Same goes for the equalizer pipe that would connect the new and existing tanks.

5 Will we eventually look into the equality in water distribution for the homes between the top tanks and the intermediate tanks? 6 No work will be done Saturday or Sunday.

VFD suppliers should be open saturday. AB

7 How frequent is the tank construction crew getting paid? Daily/weekly/lump sum? And what amount?

See the below document (rate and period) AB:

8 I don't want to get too demanding, but with the rate of work getting done, is it wise to consider asking the tank construction crew (thru Daniel) to submit daily or weekly progress reports?

See above, came from Daniel. He can do it weekly or biweekly. AB

9 How many pumps are responsible for supplying water to the community?

Two, submersible and booster. It will stay that way, with VFD on the booster. AB

10 How is Sister Gloria supposed to pay any bills being received realted to our project? I'm aware that Rotary funds are running low. (And as I've said before, we can pull money from the general chapter account when necessary)

11 In reference to the community system drawing (it has the new supply piping designated in red); the replacement starts north at junction point of streets. Why was that location selected?

This is the closest tie-in point to the main supply line under Calle Principal. AB

12 It was noted earlier by Brian that more info is needed for the area of the village along the dirt road leading NW from the new tank. What specifically is needed? The altimeter is not working properly, btw,

Have you read the instructions? Checked the battery? It has to be calibrated. It mesaures relative altitude. I know it's not very accurate. We need altitude readings in this area. AB

13 I read the emails from today regarding the VFDs. We will wait until Monday to actively research and possibly get quotes from vendors. If Daniel is going to be at the village (as I'm told he would be), we want to be there to get some questions answered. We'd probably split up on Monday if the concrete pouring for the tank roof goes as scheduled (some at the village, other(s) speaking with VFD contacts).

We went straight to the <span style="background: none !important; border-image: none !important !important; border: currentColor !important; display: inline-block !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; text-transform: uppercase !important; vertical-align: baseline !important; width: auto !important;"> after landing and got settled. In speaking with Project FIAT members who were at the site today, the construction crew was still working on the tank. Tomorrow will be our first day at the site. I spoke with Daniel via phone shortly after arriving at the airport, and he indicated he will likely be at Las Delicias tomorrow.
 * Day 1 (Wednesday, 8/8)**

-

Daniel sent us an update, photos of the work done to date on the new tank construction: (Side view of the new tank)
 * August 1**

(View from the top of the new tank) -

__** Tom's trip **__

Flew into El Salvador around noon. Immediately upon arrival the groups from Seattle and Vancouver were leaving for the orphanage for the grand opening of the playground that they built during their stay here. We spent the afternoon at the orphanage to play with the kids after a brief opening ceremony for the brand new playground.
 * Day 1 (Sunday July 15)**

Went to Las Delicias w/ volunteers from Seattle and Vancouver. We arrived on site at 9:45 am after a 45 min pit stop at a store for the volunteers to purchase various souvenirs. When I arrived, Miguel (Foreman) was there supervising 3 mason/brick layers and two helpers. Here is a photo of the tank at the beginning of the day:
 * Day 2 (Monday July 16)**

I asked to speak to Daniel Rivera so Miguel called him from his phone. I set up a meeting to meet with Daniel on Tuesday morning and reminded him that the Mayor will be coming to Las Delicias Tuesday as well. I will plan on getting status updates from Daniel on supplies, budget, and timing.

The crew is still working on the side walls. We began to move things along by helping to sift the sand for the mortar, hoist buckets of mortar to the bricklayers on the inside of the tank, re-position concrete blocks in piles evenly around the tank for ease of access when completing the outside wall, and back-filling the trench around the outside of the tank base:

Today's progress: When we arrived, the crew was finishing the inside wall layer 14/15. By noon, the inside layer of the wall was complete, as well as back-filling 1/2 of the tank base perimeter. This was apparently enough to call it a day according to Miguel, so that was it for the day. See progress below:

I did manage to get a timetable from Miguel for the remaining wall: Tuesday 7/17 - Wednesday 7/18 - complete layers 10, 11, 12, 13, 14, 15 of the outside wall. Thursday 7/19 - Saturday 7/21 - complete sika/mortar mix to line inner walls, outer walls, and inlet/outlet of piping (Side wall complete).

Tomorrow: I expect to meet with Daniel to discuss the supplies for the side wall liner (sika/mortar mix), the roof (concrete, pine boards, etc.), and the valve box (valves, concrete, pine boards). I will also discuss other supplies that might be needed so that this project doesn't experience unnecessary delay. I will also get from Daniel an update on the budget and how much is needed to complete the project. I will discuss with him the timeline that I discussed with Miguel and the plans for next week. Finally, we will talk with the Mayor and remind him to start digging the trench as they have excavators. I saw the note from Rich about the path, I will explore tomorrow as well. I will also discuss with the Mayor how close they are to securing the jack hammer and concrete cutters. In addition, the gasoline will be purchased tomorrow to try to start the concrete mixer. That did not happen today.

Arrived at Las Delicias at 9am. Upon arrival, the crew (Miguel, foreman, and 2 masons) had already completed 3 rows of 6 remaining rows on the outside wall of the tank. I asked Miguel to call Daniel to confirm our meeting in the morning. Daniel told me that he would be there at 11am (arrived at 12:30pm). The rest of the morning, one helper remained who was adjusting rebar around the tank perimeter. Below is a picture of the tank at the beginning of the day.
 * Day 3 (Tuesday July 17)**

Other than fixing rebar, I did not see any other progress on the tank after our arrival at 9am. All of the workers were gone by 1 pm. So below is a picture what the tank looked like at the end of the day (same as when I arrived):

The volunteers and I helped relocate/organize all the PVC piping in the community center.
 * The Mayor did have PVC piping, both 2" and 4", dropped off at the community center, along with fittings. It would appear they are going to start putting pipe in the ground next week***

I did meet with Daniel though to discuss progress, timing, materials, and next steps. Below is a recap of our discussion:

Materials:
 * Side wall
 * 20 blocks needed to finish the job Daniel brought those with him today so the crew has enough to finish the outside wall tomorrow
 * Sika 1 additive for the tank lining -- Daniel wasn't planning on bringing this to the job site until next week. Based on progress, the crew will be ready to start lining the tank on Thursday. I asked Daniel to bring the Sika 1 on Thursday to start; he told me that he would.
 * Roof
 * 5.5 cu. meters of concrete, already acquired
 * some pine wood and rebar already acquired, the remaining will be purchased the back half of this week


 * Action: Need to confirm overflow pipe diameter from new tank to existing tank; detail not on drawing***


 * Valve Pit
 * Concrete is acquired, remaining pine wood will be acquired later this week
 * I asked him to purchase the (3) 4" shut-off valves and (1) 4" check valve now. He wasn't planning on doing this until later.
 * He is holding off on purchasing the galvanized pipe until we know exactly where the valve pit is going

Below are pictures of possible locations -- I suggest piping from the existing 2" outlet from the existing tank over to the valve pit in between the two tanks where we have a lot of real estate.
 * Action: Need to confirm exact location of valve pit asap***

Timeline:
 * Wednesday 7/18, should finish the 3 remaining block layers of the outside tank wall & mortar between the two walls.
 * Thursday 7/19, should start lining the inside and outside of the tank with sika 1 additive + mortar **(est. 5-6 days)**
 * Late next week (est. 7/26), should start framework & rebar for the roof **(est. 5 days)**
 * Middle the following week (est. 8/1), should start pouring concrete for the roof **(est. 3-4 days)**


 * Notice: Daniel Rivera, Rotary Club Engineer, not here next week****

Budget:
 * So far, Daniel estimated $8K has been spent. He does not anticipate spending the entire budget, which he said was $15k. I asked for more details and he told me he would email me tomorrow. He is still waiting on quotes to finish the roof.
 * **Details:**<span style="background-color: #ffffff; color: #222222; display: block; font-family: arial,sans-serif;">**Has been spent about $ 9,000 until today****The next spending:****Steel for the top slab $1,000****Cement for finishing $400****Concrete + pump $ 900****Masons for finishing and formwork $1000****Others Sika 1, nails, wood, etc**

<span style="background-color: #ffffff; color: #222222; display: block; font-family: arial,sans-serif;">**The budget is $15,000 (Ony for the tank)**

Alternative Road: I walked the path with Daniel which I believe to be the alternative path discussed in emails, straight past the daycare center running parallel to the proposed road for the supply/distribution lines. I did not see a parallel road in between the tank and the end of the path, which appears to be on the map. I took pictures of this path which are below. The road has some concrete/rock however which would require the same tools at the concrete on the proposed road. This may not matter as I discussed supplies with the mayor (see below).

Discussion with Mayor: I met with the mayor after the festivities today. I asked him when he would start on the trenching. He told me that they were getting the concrete cutter, jack hammer etc. and that work would start next week, with the Engineer Chinchilla coming to the site to confirm activities. I spoke to Brian on the phone right after this conversation and then I went back to confirm that there would be (2) pipes, supply and distribution, in the trench, and the mayor said yes, but the engineer will also be out next week to confirm. So, based on this conversation, I was told that he will have the materials in question to begin trenching, cutting, etc. next week.

Additional Notes: I will confirm tomorrow the drainage pipe for the tank trough (discussed with Brian) to the soccer field tomorrow with the crew, and in an email to Daniel Rivera.

Additional Pics: Village Parade for Opening of the Day Care Center.

Arrived in Las Delicias at 9am. Miguel was there with the full crew, 3 mason/bricklayers and 2 helpers. They were preparing to start working on the outside of the tank this morning, mixing mortar:
 * Day 4 (Wednesday July 18)**

We ended up leaving at 1pm as this was the last day and everyone wanted to see a few more sights before we leave tomorrow. I noticed the crew took a nice leisurely 2.5 hr lunch break. By time I left, only 1.5 layers had been put up on the outside of the wall. I hope they finished the outside an filled in between the two layers with mortar by days end:

I did clarify 2 very important things with the crew that I will also put in an email to Daniel Rivera as well:
 * 1) The crew is NOT to pour concrete on for the roof until Daniel thoroughly inspects the formation and rebar
 * 2) After speaking with Brian on the phone, I clarified with the crew where the valve box is to go. I also asked them to start on the valve box now, but Miguel said "no", that he had the crew working 100% on the tank until it is finished and they would do the valve box after. I will also put this in my email to Daniel and ask him to get the valve box started. The location of the valve box that I pointed out to the crew is below (Adam, I believe you were looking at the same place):
 * Below is a picture of the inlet & outlet pipes for the new tank (burried just under this pit) and a view of where I see the pipes running down the inside of the road next to the tanks to the valve box location:
 * This is where I see the valve box going, because there is enough space to place the valve box without going into the road, it is downstream from both tanks, and can easily be made below grade of both tank discharge ports:
 * Below is a paint shop picture of how the piping would run. The supply pipe could come into here as well to supply the new tank. The existing tank has a 1" supply header that would probably cause too much back pressure for the pump if we kept it, as discussed with Brian today.

With this information confirmed for Daniel, he can purchase the galvanized pipe and nothing else is holding him back from completing the valve box before the completion of the tank, because I asked him to order the valves on Tuesday. I will ask him to do so in an email.

That was it for my trip. Had a great experience, would absolutely do it again!

- __** Adam's trip **__

Missed a connection on tuesday; had to spend a night in Houston. Arrived in El Salvadow around noon. Went to Puerta del Diablo w/ a group of volunteers from Seattle, WA.
 * Day 1 (wednesday june 11, 2012)**

Went to Las Delicias w/ volunteers from WA and Vancouver, BC. There is a foreman (Miguel Martinez), 3 masons/bricklayers and 2 helpers. The tank is coming along: []
 * Day 2 (thursday june 12, 2012)**

The foreman arrives at 9 and leaves at 3; the masons stay till 4 (i've seen them leave at 3 also). They seem to know what they're doing. I was told people from the community help out ($6/day, money from ADESCO) but haven't seen any. Sister Gloria said they were reluctunt to accept help from volunteers so i explained things to the foreman and we had 3 vounteers (plus myself) help move bricks (cinder/concrete blocks) closer to the new tank.

I went w/ one of the volunteers (Brianna) to take measurements of the electrical panels. It seems like there may be a <span style="background: none !important; border-image: none !important !important; border: currentColor !important; display: inline-block !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; text-transform: uppercase !important; vertical-align: baseline !important; width: auto !important;"> for the new drive, near the door on the left hand side or on the back wall.

I looked at the inlet and outlet piping to/from the new tank. The outet pipe (distribution) can be seen at the bottom of the tank, near the wall, protected by an empty water bottle: []

Then it goes under the tank, through an elbow, and ~4' of buried horizontal 2'' pipe. About 4' of 6'' supply pipe is also buried next to the distribution pipe. Then it goes through an elbow and emerges ouside of the tank, near the gutter: []

A length of pipe will be added to extend the supply line to near the top of the tank. Both lines will be extended after the trenching is done and the valve box is in place.

The tank has 1/2 vertical rebar between the 2 layers of bricks and thinner 3/8 horizontal/circular rebar around it. The space between, and the the incide of the brick, is being filled w/ mortar (no sika): []

They strain sand through a sieve and mix it w/ portland cement for mortar plus gravel for concrete: []

I went to Las Delicias and met w/ engineer Daniel Rivera from the Rotary. He gave me most of the money (~$1200) he owed sister Gloria (he still owers over $500). We helped strain sand and mix mortar.
 * Day 3 (friday june 13, 2012)**

They haven't used any sika sealant yet. They intend to use a mixture of sika and mortar to line inner walls of the tank to make them waterproof. They also intend to seal the inlet and outlet piping w/ sika flex.

Daniel will procure pine boards to be able to do the concrete roof. He says plywood is too expensive. They will finish the outer walls next week and be ready to get started on the roof. They will bring a truck of pre-mixed concrete for this purpose.

I explaned that we need a new valve box and that it is part of Daniel's scope. We located a possible place to put it. They will have to buy the valves.

They will put the access ladder at the end. They said Rich told them the chidren may climb to the roof. They will make the bottom of the ladder high off the ground.

They are aware of the vent pipe (they will put it later). They were not sure they need an overflow pipe as the old tank has one and they are connected. I told them this is part of the plan (is it?). They will need more information about the pipe connecting the two tanks: material (i told them galvanized steel; the same as others) and size. Does it have to penetrate the wall of old tank as shown on the drawing (they can do the opening) or enter though the roof?

I met w/ the ADESCO's president Don Rene Quevedo (tel. 7458-4150) and Alfredo Torres.We talked about trenching and the help of the Mayor's office. I called engineer Chinchilla at the Mayor's office (tel. 7842-8457). They still don't have the 400 m of supply/distribution piping. We lost reception. Don Rene told me the office has excavators but not concrete cutter and jack hammer; they will have to get it from an outside company. I told them there is no point in waiting for the tank to be finished; they can start digging the trench as soon as they are ready. The Mayor Romeo Varillas will vist the new daycare center, close to the new tank. Then there is an opportunity to talk to the Mayor again, show him the progress, and remind him to help out. Rene will talk to the Mayor; Tom McIntyre should be present. One-day progress: [] []

I visited the site w/ Oscar Ramirez from HIDROTEC to talk about the VFD and see the existing controls. He says it's possible to put a new booster on top of the cistern (he would need a drawing of the cistern - whether it's reinforced concrete) but he prefers the VFD solution. He says those things are about 40% more expensive in El Slavador than in the U.S. but we can save on shipping and use their experience (20 years in El Salvador, 60 in Guatemala). He says, since we have a control <span style="background: none !important; border-image: none !important !important; border: currentColor !important; display: inline-block !important; float: none !important; font-weight: bold !important; height: auto !important; margin: 0px !important; min-height: 0px !important; min-width: 0px !important; padding: 0px !important; text-decoration: underline !important; text-indent: 0px !important; text-transform: uppercase !important; vertical-align: baseline !important; width: auto !important;">, we don't need a protective enclosure for the VFD.
 * Day 4 (saturday June 14, 2012)**

In the afternoon we worked on house construction for Project FIAT. I also measured the length of concrete paving for trenching. For the proposed path it's about 90 yards; it's about the same if we tied in at the Crossing as the path to school is also concrete. We should take a look at one more road further down - it should be all dirt. Rich says it's hard-packed.

It turned out the mechanical concrete mixer only needs gasoline. We will get 3 gallons on monday and we can use it at the tank construction site (instead of mixing by hand).

Tomorrow i'm going back. I think it's important Tom and Rene talk to the Mayor during the dedication of the daycare center. They can even start excavating the trenching before** they get the concrete cutter, jackhammer, and the piping.
