• Feasibility

• Transmission Main

• Distribution Network

• Float Valve Tank

• Sustainability


El ChaguitePopulation: 333 people


Overall Feasibility


• Water Source : 15.52 gpm (22,348 gallons/day)

• 25 year projected demand: 12,755 gpd

+4,350 gpd (Irrigation use)

17,105 gpd• Diurnal Demand Cycle

• Conclusion: Feasible with water storage tank

Design Process


• Excel water flow model• WaterGEMS flow model• Multi-phase implementation

• Phase 1 (COMPLETE)– Construct Transmission Main– Instruct villagers on

construction of distribution system

– Build break pressure tank (float-valve tank)

• Phase 2– Water storage tank– Inspect village-constructed

distribution system

Building Materials


Sustainability• Extra materials supplied for maintenance and replacement.

• Locals will be educated on water conservation and proper system maintenance.

• Water Board willcollect usage tax to fund future repairs.

• Simple design and construction


Community Ownership & Education


• What kind of help will the community be providing?– Labor (digging trench, laying pipe, mixing cement, transporting

materials).– We will coordinate a schedule of construction with El Chaguite’s

Water Board.

• Who will own the project once it’s completed? – El Chaguite will own the water system upon completion of the

project. The El Chaguite Water Board will manage the communally used infrastructure.

Community Ownership & Education


• Who will be overseeing maintenance once the team leaves and how will repairs be paid for?– El Chaguite’s Water Board will be overseeing the maintenance

of the system. We will leave extra materials with the villagers to take care of any immediate necessary repairs. Hopefully, with improved health, the villagers will be able to establish community funds and pay for repairs further in the future.

• What education will be provided to the community?– The community will be educated on the maintenance of the

system, and we also plan to provide information about health and sanitation. In order for this to be a successful effort we will be working with the community Water Board and local organizations to ensure that the people understand the situation and are well informed about health and sanitation issues.

Project Lead Sign-Off


• I, Daniel P. Saulnier, P.E., as the Professional Mentor of this project, have reviewed the technical and logistical contents of this project, and approve of the proposed design. I will also comply with TAC recommended changes and make suggested changes before traveling on the implementation trip.
