yep, co is 2 55 gal barrels. I know I've been looking for a home to buy in about 12 states :). I chose CA, closing in a few weeks. In any case, yes, most of the laws had been driven by the Univ of AZ. They found that letting the water go into the ground mostly feeds the trees. Very little of it goes into the actual ground water, and it takes a really long time for it to arrive. So the theory is that by capturing water and using it specifically on the things you want to water (food plants, and showering) you're conserving a fuck-ton of water. And besides, all of that water that is captured actually ends up in the ground anyway - where do you think the shower water goes when you're on septic. The point is, AZ is pretty much ahead of the game with regards to water capture and science research on it.
