SUEZ to build & operate Colaba Wastewater plant

The Municipal Corporation of Greater Mumbai (MCGM) has recently awarded SUEZ the contract to design and build the Colaba wastewater treatment facility as part of a program to develop its sanitation infrastructure to meet up with population growth. This three years construction contract will be followed by 15 years of operation amounting to a total of EUR 42M of revenue for SUEZ.

Mumbai has existing sewage infrastructure consisting of a 1,500 km network which collects 1.7 million m3/day is not enough to treat the increasing quantity of sewage water. To address this issue, MCGM has launched the Mumbai Sewage Disposal Project (MSDP) Stage-II Master Plan that covers the development of wastewater treatment and facilities by 2025 to meet the projected flows.

MSDP, which will be funded by Atal Mission for Rejuvenation and Urban Transformation (AMRUT), has proposed the upgrade of existing sewage plants and the construction of seven new ones in Mumbai localities (Colaba, Worli, Bandra, Versova, Malad, Ghatkopar and Bhandup). The newly awarded 37 000 m3/day Colaba wastewater treatment facility is part of this MSDP project.

The plant will be equipped with disc filtration & chlorination for a tertiary treatment, allowing potential reuse of treated wastewater. Equipped with SUEZ’s degremont technology AZURAIR C for odor removal, it will be perfectly integrated into its environment.
