Everyday as I drive by one of many neighborhood drainage ponds, I think about water in the Congo. If I lived in Congo, my family would be using those ponds as a water source.
Using a bio-sand filter, I plan to purify water from a drainage pond near my house. That's the worst water I can think of near me. If the purifier can cleanup water from those ponds, I will be impressed. Also, the people of rural Congo will be happy when I implement the project there.
