VA TECH WABAG (WABAG), a leading pure-play water technology multinational, announced on March 12, 2026, that it has secured a Letter of Award (LoA) from the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB).

- Refurbishment and Upgradation: Restoring the TTRO facility’s full 45 MLD capacity within a period of 18 months.

Strategic Significance and Order Classification
This project award is categorized by WABAG as a ‘Mega Order’, signifying a contract value above INR 1,000 Crores, given the extended O&M component.
