I like the idea of water catchment and the use of cisterns as storage.

Some of the home designs I've been looking at recently include rainwater-harvesting systems. In some of these they use a good portion of the house's roof area to shed and channel rainwater to filters and from there to huge cisterns.

Most of the testimonials from home owners that have catchment systems lead me to believe the plastic ones are preferable to concrete because they can handle environmental stresses better and are low maintenance.

Now, if I could only afford to build a house. <img src="/images/graemlins/grin.gif" alt="" />
