I suggest a Zero energy Biological Treatment System followed by a reed bed to treat water for reuse as well as grow vegetables/flowers and fruits utilizing the nutrients in the waste water. It requires no electricity, can be driven by gravity, provides clean potable water after treatment by microbes and root zone. Very little sludge is formed in the holding tanks. Please see if we can work together. We are presently implementing a similar system on a Drain in a major Town in Andhra Pradesh, India and are successful.
