Form 521, Nov. 1 version:

Draft recommendations:

Recomendaciones: 1/ Uno necesita substituir el tramo de tubería corto de ocho pulgadas de longitud y de tres pulgadas de diámetro (lo que tiene el problema de la corrosión – vea la foto y el dibujo) con tubería de calidad adecuada.

El plomero debe usar cinta de teflon y goma (provista) o masilla de plomería para conectar las secciones de la tubería.

2/ Vale la pena instalar ánodos de sacrifico (protección galvánica) para proteger la tubería – es barato y fácil. Más información aquí: [|http://www.factorhumano.com.do/Protecci%F3n%20cat%F3dica%20galv%E1nica%20para%20activos%20met%E1licos%20enterrados%20(ductos%20y%20tanques).htm]

Recommendations (English): 1/ One needs to replace a section of the piping 8 in length and 3 in diameter (the one that has the corrosion problem - see the photo and the sketch) with a section of adequate quality.

The plumber should use teflon tape or plumber's putty to connect sections of the pipe.

2/ It's worth it to install sacrificial anodes (galvanic protection) to protect the pipe - it's cheap and easy. More information is here: (link)

Here is the site that allows tracking lower airfares for given destination, e.g. San Salvador: []

General information regarding well construction from the State of Ohio. This gives a good overview of current well construction techniques in the US as well as several references that may be of use. A discussion of well testing for capacity and biological contamination, including sampling methods, is included.



Starting on page 12 of this document is a summary of well tests and the limits for contaminants.

Some questons and issues raised at the 4/16/09 Meeting: 1) Is there another well closer to the storage tank that can supply water while reducing the required pipeline length? Can the pump be moved if necessary? 2) Water is currently supplied to the storage tank in trucks. Does it makes sense, as a temporary solution, to load a truck at the local well and truck it to the storage tank instead of paying to truck it from a remote location? 3) Can the pipeline be installed, at least partially, above ground to avoid digging a ditch and to allow better access for maintenance? Such solutions exist in Central America and other developing regions. Is theft and/or vandalism an issue? 4) There are temporary solutions to poor water quality and parasitic worms affecting children. One such solution are ceramic water filters with colloidal silver from Potters for Peace. 5) ?

Potters for Peace: Adam got in touch w/ PFP. The filters are $25 and can be delivered to desired destination.

Here is the manual (in Spanish): filtron-esp.pdf

Buen Dia, Los Filtros cuestan $25.00, y se venden en la planta de Bio Filtros o los entregamos en el lugar segun cantidad solicitada. El Filtron, es tu Solución Claudia Martinez T/ 7724-9699

Hola,

Soy un miembro de Ingenieros Sin Fronteras trabajando en un proyecto del agua pura en Las Delicias, El Salvador. Vivo en los Estados Unidos. Quisiéramos saber cuánto cuestan sus filtros, donde podemos comprarlos en El Salvador, y cuánto agua puede cada filtro purificar por día. Conseguí sus nombres de correro electronico de Kaira Wagoner con los Potters For Peace en los E.E.U.U. No estoy seguro quién es la persona que pude contestar a mis preguntas. Saludos, Adam Brostow

One of the proposed short-term solution is the use of ceramic filters w/ colloidal silver from Potters for Peace. Adam will contact PFP to obtain more information.
