A water treatment system was designed for an existing pool structure at the Cambodian Children's Fund Kids Camp in Cambodia. The system is cost efective and reduces the use of chlorine and providing a safe and enjoyable environment. High rate sand filtration and copper/silver ionization were selected as the methods of water treatment. The disinfection system combines of copper and silver ions and low levels of chlorine to eliminate bacteria and algae. To satisfy the need for running the system off-grid, solar panels were employed as the sole power source for the design. Proposed modifications to the existing pool structure reduced pool water volume, resulting in a lower estimated capital project cost of $52,900.
