By the end of this year, the city will get an additional 150 million litres of water daily.
This will happen after the city’s first water recycling plant, at Ghatkopar, starts functioning by the year-end. The plant will generate 150 million litres daily (MLD) for non-potable use. It also means an equal quantity of drinking water will not be wasted for such non-potable use.
“The Ghatkopar plant, which will have a capacity of 150 MLD, will be activated in 8-10 months, so treated water can be used for non-potable uses and that much drinking water will be available with the BMC,” said Anil Diggikar, additional municipal commissioner (projects). The Brihanmumbai Municipal Corporation (BMC) is in the process of selecting a private operator to install and run the plant.
The rainfall shortage in the city's catchment areas during the last monsoon has resulted in a water crises, with the BMC imposing a 15 and 30 per cent water cut for residential and commercial users respectively. As against last year, currently all six of the lakes that supply water to the city have 20-25 per cent less water. Wastewater treatment plants are one of the BMC's solutions to address this crisis. The BMC has planned such plants at Ghatkopar, Versova, Bhandup and Colaba.
“We have responses from seven private firms interested in setting up the treatment plant at Ghatkopar,” Diggikar added. The other three plants, scheduled to be operational in the next two years, are expected to take wastewater treatment capacity up to 350 MLD.
Mumbai gets its daily water supply of 2,900 million litres from six lakes - Tansa, Vaitarna, Vihar, Tulsi, Upper Vaitarna and Bhatsa. Of these, Vihar and Tulsi are in the city national park area while the rest are in neighbouring Thane district.
