Keeping in mind the current water scarcity the city is facing, the law committee of Brihanmumbai Municipal Corporation (BMC), has decided to revive an old proposal to make it mandatory for all new constructions, which are either spread over 2,000 sq m or house more than 60 flats, to set up grey water recycling plants. According to officials, the civic body will ensure that builders are compensated with Floor Space Index (FSI) equivalent to the area taken up by the plant. Also, if a new structure spread over 2,000 sq m, is built without the plant, the BMC will not issue a work completion certificate to it. Through the plants, water generated from domestic chores such as bathing, washing dishes, laundry and washing food items, can be treated and used for non-drinking purposes like washing vehicles, gardening and even in toilets. Grey water, which forms 50-80 per cent of wasted water from homes, is different from that generated in toilets as it contains human waste. The civic bodies have also plans to make grey water recycling plants mandatory for old societies, who have a suction tank and overhead tank with them. By using these measures, the civic body is expected to save up to 10 per cent of potable water, which is used for other purposes like gardening, cleaning and washing. With it being one of the mandatory conditions to avail funding for any civic project under the Jawaharlal Nehru National Urban Renewal Mission, the BMC needs to recycle grey water for non-drinking purpose and stop wastage of drinking water. This has prompted the BMC to revive grey water bylaws, which were prepared in 2008, but later overlooked due to administrative apathy.
