Believe it, or not, I like this idead

Group advocates cisterns for Los Angeles.
As a means of increasing water supply, decreasing electricity usage, and providing jobs, TreePeople advocates building cisterns to collect rainwater throughout the Los Angeles area. This actually makes sense. As it is now, when it rains in LA, almost all of the water goes into the drains and out to sea. By building a massive rainwater retention system, they will be able to provide more water for the area and cut down on the electricity needed to pump the water from LA’s current sources. This system will also provide additional capacity for flood prevention.

I can actually see this being a great idea for homes in the hill country of Texas (especially rural ones). It will provide additional water that does not come from depleted aquifers. As an aside, I have part of my gutters set to drain into a rain barrel and then into a pond in my backyard. I like cisterns.

There is my obligatory Earth Day message. Remember, think Earth first! We’ll stripmine the other planets later.
