About the Project:
The project was provide a source of potable water to the Champei region of southern Cambodia.
Deliverables:
The design of a sustainable water filtration system with the capacity to serve the entire community.
Assembly and troubleshooting procedures for workers in-country.
Procedures for the use, maintenance, and repair of the filter for Champei residents.
Establishment of an advisory board of Champei residents to ensure fair and equitable access to clean water.
Our Process:
The Virginia chapter of Engineers Without Boarders was commissioned to engineer and build a clean water source.
This was an interesting challenge, because we had to design the solution using only materials available in-country. The design had to last for at least ten years, because performing repairs could be difficult or impossible.
The logistics were also unusual, because the materials had to be delivered before the construction team arrived, and construction had to be fully completed by EWB and local volunteers within two weeks after arrival.
We analyzed the precipitation and water table levels to determine that rainwater collection was the most abundant source of untreated water.
We then designed a biosand filtration system using only bricks, sand, gravel, and plumbing available in Cambodia, using the guidelines recommended by the World Health Organization.
Results:
As a result, over 5000 men, women, and children now have access to clean water. Bacterial infections have been reduced by 90%.
The sand filter is still in use today.
What the Client Said:
