Project Scope and Terms
VA Tech WABAG announced on March 12, 2026, that it has been awarded a significant 'Mega' order by the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB).
The project involves the Refurbishment, Finance, Operate, Maintain, and Transfer (RFOMT) of a 45 MLD Tertiary Treatment Reverse Osmosis (TTRO) plant located in Kodungaiyur, Chennai.
The contract spans an 18-month refurbishment period, followed by 18.5 years of operation and maintenance.
A 'Mega' order is defined by WABAG as having a value exceeding INR 1,000 Crores.
Why this matters
This new order significantly reinforces VA Tech WABAG's position as a leader in advanced water recycling and reuse solutions.
It aligns with Chennai's broader goals of transitioning towards a circular water economy and achieving sustainable industrial water management.
The long-term operation and maintenance component ensures a sustained revenue stream for the company.
Company Context and Past Performance
VA Tech WABAG is a leading Indian multinational company specializing in total water solutions, with a global presence.
The company maintains a robust order book, exceeding ₹16,300 crore as of March 2026, with international projects contributing significantly to its revenue visibility.
In the past year, WABAG has secured large orders, including a ₹3,251 crore sewage treatment plant project in Saudi Arabia and an ADB-funded water treatment plant in Nepal.
However, the company also experienced a setback when a ₹2,700 crore desalination project in Saudi Arabia was cancelled in December 2024 due to administrative reasons, impacting its stock price.
Historically, WABAG faced cash flow challenges in FY15 due to delayed payments from government projects, highlighting potential payment risks in the sector.
CMWSSB itself is a major player in Chennai's water infrastructure, undertaking projects like a ₹2,423 crore Ring Main Pipeline project.
What changes now
The company's order book is further strengthened with a long-term, value-accretive contract.
WABAG's leadership in water recycling and reuse technologies is reinforced, especially in a key municipal market like Chennai.
The RFOMT structure provides a predictable revenue stream for nearly two decades post-refurbishment.
This award deepens WABAG's engagement with the Chennai Metropolitan Water Supply and Sewerage Board.
Risks to watch
Successful execution of the 18-month refurbishment phase within budget and timeline.
Ensuring profitable and efficient operations during the 18.5-year O&M period.
Potential for payment delays or policy changes from government entities, a historical concern for the sector.
Client-specific administrative risks, as highlighted by the recent cancellation of a Saudi Arabian project.
Peer comparison
VA Tech WABAG operates in a competitive landscape with players like Ion Exchange (India) Ltd., known for its pioneering work in water treatment; Thermax Ltd., focusing on sustainable industrial solutions; and global entities like Suez Water Technologies & Solutions.
