Koyambedu Tertiary Treatment RO Plant Receives 2020 GWI Distinction Award for Wastewater Project of the Year

IDE is excited to announce that Koyambedu has won the 2020 GWI Distinction Award for Wastewater Project of the Year at the Global Water Awards, recognized for great innovation in optimizing its environmental footprint

The Koyambedu Tertiary Treatment RO plant is India’s largest, most technologically advanced water reuse project and the first reuse facility in India to use ozonation for disinfection, a crucial step in the country’s plans for municipal water recycling. The project will boost water resilience and sustainability, making the city of Chennai the first in India to reuse more than 20% of its treated water – freeing up 16 million m3 of freshwater each year for the more than 10 million people living in Chennai.

The plant uses a multi-stage treatment scheme – including ultrafiltration, reverse osmosis, rapid gravity said filters, and ozonation – and functions with an ultra-low specific power requirement of 1.88kWh/m3 to cut operating costs over the next 15 years.

Under India’s AMRUT program, IDE joined VA Tech Wabag in the $83 million, 15-year design-build-operate contract with the Chennai Metropolitan Water Supply and Sewerage Board to complete the 45,000m3/d reverse osmosis plant and transmission pipeline to treat wastewater for reuse at an industrial hub.
