India’s largest recycled water masterplan for the Brihanmumbai Municipal Corporation (BMC) is in preparation. For this, BMC has roped in US-based Black & Veatch, who will deliver this project through a combination of local and global expertise. The recycled water masterplan is the company’s second marquee project win with BMC in the last 12 months. The project, once commissioned, is likely to be one of India’s largest in terms of treatment capacity.
In view of new discharge standards by the Central Pollution Control Board, BMC is planning to include tertiary treatment for a portion of the flow, and recycle the tertiary treated effluent for non-potable reuse.
BMC’s vision is 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. Using tertiary treated effluent could potentially defer the need for additional water supply projects, preserve raw water resources, and pave the way for sustainable growth.
The strategic recycled water masterplan will outline the framework for reuse of tertiary treated effluent from all seven of Mumbai’s wastewater treatment plants, and serve as a guiding document to build infrastructure for recycled water in a phased manner.
In May 2016, the company was awarded the contract to undertake consultancy services, and prepare a detailed project report and tender documents, for BMC’s wastewater treatment facility for Malad zone.
