Recycle and Reuse: Plan to Convert 260 MLD Sewage into Fresh Water

With groundwater levels hitting rock bottom and monsoon failing almost every alternative year, city’s water woes could only worsen. To tide over the impending crisis,  the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) has come up with a proposal that assures regular supply of 260 MLD (million litres per day). The plan is to recycle sewage into potable drinking water by setting up tertiary treatment plants, costing over `1,000 crore!

The treated water will be released into identified water bodies for recharge and pumped back into city’s  water distribution network.
