Water technology major VA Tech Wabag has secured a mega contract of above Rs 1,000 crore from Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) for the refurbishment and long-term operation of a 45 million litres per day (MLD) tertiary treatment reverse osmosis (TTRO) plant at Kodungaiyur in Chennai.
The project will be executed under the public-private partnership (PPP) model and involves refurbishing, financing, operating, maintaining and eventually transferring the facility back to the civic body.
The TTRO plant, along with its associated distribution pipeline network, was originally developed by CMWSSB in 2019 to supply high-quality treated wastewater to industries located in the Manali–Ennore and Manali–Minjur industrial corridors in the city.
Under the new contract, Wabag will refurbish and upgrade the existing facility to restore its full treatment capacity of 45 MLD within 18 months. After completing the upgrade, the company will operate and maintain the plant for 18.5 years, ensuring reliable supply of treated water that meets the agreed quality and quantity standards.
The latest order further strengthens Wabag’s footprint in advanced wastewater recycling and industrial water reuse solutions.
The company already operates another 45 MLD TTRO facility at Koyambedu in Chennai, which was designed, built and commissioned by Wabag in 2019 to supply recycled water to industrial consumers. In addition, it runs a 40 MLD TTRO plant in Ghaziabad that supplies treated wastewater to industries in the Sahibabad Industrial Area under a PPP model.
According to the company, the Kodungaiyur project will play a key role in supporting sustainable industrial water management and promoting water reuse in Chennai’s industrial ecosystem.
Wabag whole-time director and chief growth officer S Varadarajan, said the project reinforces the company’s leadership in the Indian water sector and strengthens its position in water recycling and reuse solutions.
He added that such initiatives will be critical for sustainable industrial water management and for supporting Chennai’s long-term water security through a circular water economy.
