The Story:

Chennai Metrowater is moving closer to implementing round-the-clock piped water supply in the Adyar zone by evaluating tenders for a concessionaire. This project aims to address the growing water demand resulting from increased apartment complexes in the area, replacing independent houses. The initiative seeks to provide continuous and equitable water supply to 38,866 households across several wards, ensuring residents receive 150 liters per capita per day (lpcd), aligning with Central Public Health and Environmental Engineering Organisation norms.

The project, with an estimated cost of ₹ 271.50 crore, will upgrade water distribution stations with automated controls and SCADA-enabled real-time monitoring. Water will be sourced from the 110-mld Nemmeli desalination plant and 530 mld Chembarambakkam water treatment plant. The Water Corporation of Odisha (WATCO) will serve as the project management consultant, drawing from its experience with the “Drink from Tap Mission” in Puri, Odisha.

Key Points:

  • Chennai Metrowater is evaluating tenders for a concessionaire to implement a 24/7 water supply project in the Adyar zone.
