I am in discussion with a land owner who is considering building a set of homes that are net zero in water (and energy).

Net zero in water means both capturing rainwater for filtering and drinking as well as processing own nutrients (fecal and urine) for re-utilization on the land.

Might someone have any research you could point me to on the health and safety of such systems, as well as the ability to process pharmaceuticals?

Thanks in advance for your thoughts.

Best,
David Burdick
