Our first and favorite testing facility: family and home. Five people. Dogs. Cats. Chickens. Fruit trees. A vegetable garden. A swimming pool. We had a small roof at first, and one tank. Then, a bigger roof. We learned a lot about water conservation along the way.
One reason we know so much about rainwater harvesting systems parts is that we have tested on ourselves everything we sell. We know what works and what fails. There's nothing like coming home and hearing your happy family never complain about dad's crazy cistern system.
These days, "green" and sustainable building is getting a lot exposure in the news, on cable TV shows, in magazines and... oh yeah.. the web. Back in 1992 our founder Charles Gibson helped start a little citizen's group in Austin , Texas called "The Sustainable Building Coalition" (now called "Design~Build~Live.") This group was to be the civic companion to the City of Austin's Green Building Program (now part of Austin Energy). Charles believed that our future was going to depend on this "sustainability" thing, whatever that meant. He still believes this. And harvesting rainwater is a great place to start, because the health benefits are immediate.
