Clean & Safe Drinking Water by Save the Children USA
Pond water is a great source of drinking water because of its low iron content. In this region, Save the Children USA builds something called a Pond Sand Filter which helps turn pond water into safe and clean drinkable water.
This photo was taken near a recently constructed pond sand filter. I tried the water myself - it ain't bad at all.
This photo is a supplement to a couple of videos I have on YouTube where you get to vote on how I help Save the Children USA, you can see it here:
