Trathen Heckman takes us on a step-by-step tour of how to make a safe, ecological and legal suburban home graywater system. Follow the water as it drains from the bathroom tub (and sink and laundry) through a unique valve leading into the backyard garden. It flows into an optional wetland and underground pond for filtering. The water is then piped below ground to several destinations in the yard, where it will supply water for plants growing above it. Trathen discusses the process with local government agencies, the system design and construction (with pictures), costs, resource books, and why to undertake a graywater system in the first place.
