Suez bags €42 mn Colaba wastewater treatment project

New Delhi : French water major Suez has bagged a major contract in Mumbai for designing and building the Colaba wastewater treatment facility. The three-year construction contract will be followed by another contract to operate the wastewater plant for a period of 15 years.

Suez said the Municipal Corporation of Greater Mumbai (MCGM) awarded it the contract as part of its overall programme to develop the city's sanitation infrastructure to meet up with population growth.

The Colaba wastewater treatment plant will have a capacity of 37,000 m3/day. The overall contract will fetch Suez a total of €42 million of revenue.

Mumbai, with a population of more than 15 million, has seen intense urbanization and population growth over the last few decades resulting in increasing pressure on water resources. Wastewater management has emerged as a key concern area for the local authorities.

The 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.

MCGM has, therefore, 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.

As part of the MSDP, which will be funded by Atal Mission for Rejuvenation And Urban Transformation (AMRUT), an upgrade of existing sewage plants and the construction of seven new ones in Mumbai at Colaba, Worli, Bandra, Versova, Malad, Ghatkopar and Bhandup, has been proposed.

Suez said the plant will be equipped with disc filtration & chlorination for tertiary treatment, allowing potential reuse of treated wastewater.

“We are proud to be part of the ambitious project that MCGM has undertaken to tackle the wastewater issue for the city of Mumbai and its inhabitants. We are committed to tackle water challenges in India by providing innovative and tailor-made solutions to local authorities to improve water distribution services and ensure access to efficient sanitation services for heavily populated cities like Mumbai", said Suez's senior executive vice-president in charge of the international division Marie-Ange Debon.

The company said it has been supporting MCGM in improving the drinking water quality for Mumbai for over three decades. Suez has designed and built drinking water treatment plants at Panjarapur and Bhandup, having a combined production capacity of 3.4 million m3/day, for over 15 million people in Mumbai and Greater Mumbai region.

It is also presently working with MCGM in a contract to build and operate a new drinking water treatment plant at Vihar Lake. It is also supporting MCGM in implementing the water distribution system improvement programme (WDIP) to improve drinking water networks and distribution conditions to Mumbai’s inhabitants, under a five-year contract worth €31 million.

Why forests should take centre stage during the water decade

Only a tiny fraction of national biodiversity plans consider the impact of forests on water supply, and only a fraction of national water plans place ecosystems at their centre.
