About the entity

As an expert in water and waste for 150 years that is present on the 5 continents, SUEZ harnesses all its capacity for innovation to work for the efficient and sustainable management of resources.

Municipal Corporation of Greater Mumbai (MCGM), the public utility board in charge of potable and municipal wastewater management for the city of Mumbai, has awarded Suez a contract for an amount of 700 million euros to design, build and operate (DBO) 500 MLD capacity Wastewater Treatment Facility at Worli, Mumbai, to serve a population equivalent of 2.5 million. This contract award, the most important in terms of value SUEZ has ever won in India, strengthens the company’s position in one of its main and most promising international markets.

For the first time in the city of Mumbai, the treated effluent shall comply with the most stringent quality standards mandated by the National Green Tribunal of India for effluent disposal in water bodies. Biosolids shall comply with U.S. Environmental Protection Agency (USEPA) class-A biosolids classification for safe land disposal, and up to 50% of the treated effluent shall be further treated for non-potable reuse.

SUEZ’s state-of-the art technologies combined with innovative process and plant design shall deliver all this while using 50% less available space than normally required, and keeping operational the existing facility, until the new modern systems come online.

The project features several of SUEZ’s in-house wastewater most advanced technologies - DENSADEG high-rate clarifier, ULTRAFOR membrane bio-reactor (MBR), Drainis GDE mechanical sludge thickener, DIGELIS BH boosted digestion of sludge technology, and AZURAIR odour control unit. The biogas produced in digestors will be used for on-site production of up to 39 GWh per year of green electric energy, making the plant up to 75% energy self-sufficient, and one of the smallest carbon footprint wastewater treatment facilities of SUEZ in India. Chlorine-free discharge of treated effluent in the Arabian Sea will further safeguard the aquatic & marine ecology

The total duration of the contract is 20 years, comprising of 5-year period for design and build, followed by a 15-year period for facility operations and maintenance.

Sabrina Soussan, Suez Chair and CEO, said: "The long-standing partnership between Municipal Corporation of Greater Mumbai (MCGM) and Suez spans over four decades. It rests on Suez’s consistent contractual performances and shared commitment towards access to water services and the ecological transition. The contract for WORLI wastewater treatment facility is a mark of trust MCGM has in Suez’s ability to deliver the advanced treatment solutions, meeting the stringent statutory standards. Beyond that, this contract award illustrates our progress towards a diversified and geographically balanced business which is at the heart of our new strategic roadmap I have announced."
