To recycle and reuse 4. 85 lakh litres of wastewater in four slum clusters in South Mumbai, the BMC is establishing four decentralized sewage treatment plants (STPs) as part of a pilot project. At present, sewage from these slums is discharged into the sea.
“By treating their wastewater, the BMC aims to promote environmental sustainability and maximize resource utilization by using the treated water in toilets and parks,” said a civic official.
The STPs vary in capacity, with the smallest being 35 kLD (kilo litres per day) at Darya Sagar slum near Mahalaxmi. The largest, of 300 kLD capacity, is at Markandeshwar slum. The remaining are 100 kLD, at Darya Nagar, and 50 kLD, at Shivaji Nagar near Tata Garden.The project, named ‘Integrated Wetland Technology’, is being implemented by SMILE Council, which is the BMC’s civic-tech incubator. The project’s funding is by the BMC through its Innovation Implementation Fund. The solutions have been developed by the start-up Emergy Enviro.
