Gujarat’s Urban Development Department is considering incentives for setting up greywater treatment plants in new and existing residential and commercial projects. Grey water generally constitutes wastewater from bathtubs, showers, bathroom washbasins, washing machines, sinks, and laundry tubs. It does not include toilet discharge water. An analysis by the Pandit Deendayal Energy University, Gandhinagar, recently observed that a domestically produced grey water treatment system would cost Rs 187 per sq m per year. Grey water recycling can ease problems of scant water supply in residential and commercial buildings. One of the two treatment processes that are being proposed is the hybrid system that comprises a natural filtration unit with a bioreactor system.
