The New Create an Oasis with Greywater: Integrated Design for Water Conservation

Excelent book. Lots of infomation. Highly recommended!

Clearly no-one has done more research on the subject than this guy. Maybe for a layman this book is adequate, but greywater is not rocket science, and i feel the way each "system" is categorised is a bit over the top. I would prefer to learn the basic principles and have a few examples of systems. Instead, he labels each system based on slightly different components, but in essence they all do the same thing. Like the "branched drain" system. It's just branches coming off of single drains. No need for a dedicated section on it. If you're a complete beginner I'm sure this is the book for you, but if you're a bit inventive or technical you can figure out most of this stuff for yourself and on t'internet
