Clean Water for over 4,000 people in Honduras

Post Assessment Report

Executive Summary

The community of El Negrito, Honduras is currently supplied with domestic water supply from five sources. No water supply for firefighting purposes was identified.

The services currently serve about 1320 homes and approximately 10,000 residents.
Peace Corps volunteers working in the area reported to Engineers Without Borders –South/Central Florida chapter (EWB-SCFL) that the water supply to the residents is inadequate and there is indication of pollution resulting in water borne diseases.

EWB-SCFL visited the community of El Negrito during the week of September 19th to 26th to evaluate the report and to determine further involvement as may be required to improve the water supply and to alleviate the adverse impact on the population.

Meetings with the Mayor, Delvin Salgado, confirmed the number of water sources, the inadequacy of the current system, and the desire to upgrade to a single system to serve the entire community. This would involve a phased development with the addition of a 150,000 gallon storage tank in the first phase. The flow would also need to be improved by increasing the pipe size and fixing the numerous leaks in the system. Upgrading the pipes will induce heavier loads on the catenary support which should undergo structural evaluation. This evaluation is outside the scope of EWB/SCFL.

The EWB team’s field visits and engineering analysis supports this concept. It is however imperative to note that the current distribution system is not fully understood and for this concept to be effective that system would have to be fully understood and integrated. This effort is outside the scope of EWB-SCFL scope of activities.


Meetings with Dr. Carla Suyapa Fuentes and Dr, Juan Valesquez Ramon confirmed the existence of water borne diseases in the community. Field survey of residents and field water analysis support this view. Some form of purification will therefore be necessary in a long-term solution.

Population growth and subsequent water demand were calculated based on parameters supplied by the El Negrito Municipality. The current population is approximately 10,000 people with a population growth of 3%. Using these estimates, population in the year 2029 will be 17,535. This translates to a water demand of 208 gpm in 2010 and 365 gpm in 2029 and a needed storage of 160,000 gallons. The current tank size is 41,000 gallons. Current required storage is 90,000 gallons, meaning a shortfall of 49,000 gallons. Again, these numbers do not consider water for fire flow.

EWB/SCFL will proceed to evolve systems pertinent to the Pico Pijol system in a manner compatible with phased construction and to meet demands as dictated by the parameters noted above. This information will be supplied to the Mayor for his review and decision to have the detailed design completed by El Negrito engineers and implementation as he sees fit.

EWB-SCFL wishes to extend their appreciation to the people of El Negrito to be of service to them and would extend their desire to be of continued service.
