MUMBAI : The Municipal Corporation of Greater Mumbai (MCGM) has awarded consultancy Black & Veatch a contract to prepare what is being considered India’s largest recycled water masterplan.

MCGM’s plans to maximise the use of tertiary treated effluent over the next 50 years in order to offset fresh water demand and alleviate the anticipated deficit in water supplies.

In view of new discharge standards by the Central Pollution Control Board, MCGM is planning to include tertiary treatment for a portion of the flow, and recycle the tertiary treated effluent for non‐potable reuse.

Currently, Mumbai’s sewerage system consists of approximately 1,900 km of sewer network, 51 pumping stations and seven wastewater treatment plants (WWTPs).

The Strategic Recycled Water Master Plan will outline the framework for reuse of tertiary treated effluent from all seven of Mumbai’s WWTPs and serve as a guiding document to build infrastructure for recycled water in a phased manner.

“Water reuse is a win-win for Mumbai,” said Anand Pattani, managing director, Black & Veatch India. “Treating wastewater to a tertiary standard provides significant health and environmental benefits. Reusing that treated wastewater could relieve the pressure on the city’s potable water supply.”

In May last year B&V was awarded another MCGM contract to undertake consultancy services for a wastewater treatment facility for the Malad zone.
