Have you ever dreamed of building a rainwater collection system for you home, one that will make your entire home totally water independent? Sustainable rainwater catch systems are becoming more reliable, and perhaps more affordable, than you might expect.According to rainwater.org, you're looking at around $15,000 to construct a 1st-rate, whole-house system. That includes everything from the tank to the ultra-violet lights. Not to mention, some local governments are offering incentives for rainwater collection and green building projects. If that's too rich for your blood, you can do a more affordable supplemental system such as rain barrels.
As a reference guide, rainwater.org offers a pretty complete set of information, including a book and video of how to build your system from the ground up. Chapter 1 of the book -- which you can view online -- discusses practical things like how much water you'll need and how much can be harvested per inch of rainfall, so you can take your local rainfall situation into consideration before building.
