VA TECH WABAG Wins Mega PPP Contract for 45 MLD TTRO Plant Refurbishment in Chennai

VA TECH WABAG has secured a Letter of Award from Chennai Metropolitan Water Supply and Sewerage Board for the refurbishment, financing, operation, maintenance and transfer of a 45 million litres per day Tertiary Treatment Reverse Osmosis (TTRO) plant at Kodungaiyur in Chennai. The project will be executed under the Public-Private Partnership (PPP) model and is classified as a mega order, indicating a contract value above Rs 1,000 crore.

The TTRO plant and its distribution pipeline network were originally developed by CMWSSB in 2019 to supply treated wastewater to industries in the Manali–Ennore and Manali–Minjur industrial corridors. Under the new contract, WABAG will refurbish and upgrade the facility to restore its full treatment capacity of 45 MLD within 18 months.

Following the refurbishment phase, the company will operate and maintain the plant for 18.5 years, ensuring a reliable supply of treated wastewater that meets the required quality and quantity standards for industrial use. The project is expected to strengthen sustainable water management and support industrial water demand in the Chennai region.

Notably, WABAG is already operating the 45 MLD TTRO facility at Koyambedu, Chennai, which was designed, built, and commissioned by WABAG in 2019 to supply high-quality recycled water to industrial consumers. WABAG is also operating a 40 MLD TTRO facility in Ghaziabad, developed by WABAG under PPP mode, which supplies treated water to multiple industries in the Sahibabad Industrial Area, thereby supporting sustainable industrial water reuse and circular water management. The Kodungaiyur TTRO facility award further strengthens WABAG’s leadership in advanced water recycling and reuse solutions, reinforcing its role in enabling sustainable industrial water management and supporting Chennai’s transition towards a circular water economy.

Commenting on this development, S Varadarajan, Whole Time Director & Chief Growth Officer said, “We are delighted to secure this prestigious Recycle & Reuse project from our valued client, CMWSSB. We thank them for their continued trust and confidence in our technological expertise and execution capabilities. This project further strengthens our leadership in the Indian water sector and reinforces our position at the forefront of water recycling and reuse, which will play a critical role in enabling sustainable industrial water management and supporting Chennai’s long-term water security.”
