As the city stares at the risk of running out of water by next decade, a diverse team comprising of OOZE Architects, Madras Terrace, Care Earth Trust, IIT Madras, Biomatrix Water, IRCDUC, Uravugal Social Welfare Trust, Paperman Foundation, and Goethe Institute, have come up with a strategy, the Chennai-Wide Water Balance Model.
The pilot has been initiated at the Little Flower Convent in Mambalam. The project, known as ‘City of 1,000 Tanks’, has a vision for the city’s water security. The team will develop a Water Balance Model across the city by collecting rainwater, treating wastewater and runoff pollution with decentralised Nature-Based Solutions, and recharging the underground aquifer. Chennai-wide water balance model will be started with pilot projects, then upscaling to flagship projects before effective city-wide implementation. Each upscaling stage is an opportunity to build capacity and improve performance to demonstrate inclusive implementation for a water-rich Chennai. The initiative will help prevent droughts by increasing groundwater reserves while simultaneously mitigating risks associated with high-frequency floods and sewage pollution.
