One technology that may be of interest to you is called Bioremediation. The specific species of microbe used is called Archaea. To date is it the only 100% recycle of waste water and all waste. Some of the devices used in this process are 1. biodigester (breaks down all organic matter to its elemental/nutritional state.) 2. Bio Generator (this collects and stores the electrons created during the bioremediation process = electricity). 3. Rain water collection items (Metal roofs, gutters connecting pipes, rain barrels, pumps, elevated tower, and most important a very large cistern). This is all part of being 100% off the grid and 100% sustainable.  In case your were wondering no chlorine is required. Also all toxic compounds are chelated into their elemental non toxic state as micronutrients for your immune system to function.  If you are in Chile you may contact me by using skype: guy_mcgowen.  I have instructed many pre and post doctorates.  This is very cutting edge technology. Most municipalities use 1950 technology.
