Pond Sand Filter – Pros & Cons
Thursday, August 20th, 2009
The Pond Sand Filter is a device that takes pond water and makes it safe to drink by filtering out bacteria that is harmful to human beings. It’s a proven technology but it has its limitations.
Pros
- No fossil fuels, solar power, or electricity required
- Nearly effortless to pump
- Purifies enough water everyday to provide hundreds of families clean & safe drinking water
- The water purified is safe enough to be used for cooking (low or no iron in the water)
Cons
- Limited lifespan (minimum two years), needs to be replaced eventually like any filter
- Increased complexity vs. the deep tube well (Murphy’s Law – more can go wrong)
- More vulnerable to vandalism than a deep-tube well (can unscrew and steal the faucets, etc)
The person in the video is a local villager. She’s not an expert in pond sand filters – but I wanted to see what the local perception of Pond Sand Filters are.
