VA Tech Wabag secures LoA from CMWSSB
Mar-14-2026

VA Tech Wabag has secured a Letter of Award (LoA) from the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) to develop a looped transmission network under the Chennai Climate Resilient Water Security and Sewerage Project (CCRWSSP) for Greater Chennai City (GCC). Funded by the Asian Development Bank, the project will establish a city-wide water grid platform for Chennai, enabling flexible water routing, improved pressure management, and greater operational reliability under both normal and emergency conditions. This Project will be executed by a Joint Venture where Wabag will be the Leader.

The project is particularly significant given Chennai’s long-standing challenges of water scarcity, uneven distribution, and periodic supply disruptions further intensified by climate variability and the city’s dependence on distant surface water sources. The proposed ring main system will form the backbone of Chennai’s water grid, strengthening the city’s bulk water transmission network. By interconnecting existing and new pumping stations, service reservoirs, and key network nodes, the system will enable dynamic balancing of water flows across zones, reduce reliance on single transmission corridors, enhance resilience to supply disruptions, and ensure more equitable and reliable water distribution across the city. Beyond physical infrastructure, the project will introduce digital monitoring, automated control, and performance-based operations and maintenance, enabling smarter network management and strengthening CMWSSB’s operational capabilities. 

The scope of this project includes development of bulk transmission pipelines, feeder mains, pumping stations, and underground tanks, along with integration with the central SCADA system and testing and commissioning of the entire network. The project will be completed within 54 months, followed by 10 years of operation and maintenance. Once operational, the system will establish a climate-resilient water grid for Chennai, significantly improving the city’s ability to manage water resources efficiently, respond to disruptions, and ensure reliable and sustainable water supply for its growing population.

VA Tech Wabag is an India-based company engaged in the business of water treatment field.
