Living Machines as envisioned by Dr. John Todd

Living Machines have been developed throughout the world as a sustainable method of servicing a communities waste (black) water by using a process that mimics a natural process found in wetlands, Findhorn built one in the mid 90's.

It is really very cool and I urge you to read about these systems (click on "Living Machines" above), if you have an interest in alternate methods of treating black waters as compared to the methods used by the majority of cities in the US that I know about.
