Chennai Wastes
Graphic Map showing state of Solid Waste management in Chennai. Where does your waste go?

Apart from 5000T/day of waste transported outside the city, 1250T fall out of the system and remain uncollected inside Chennai. This solid waste is unceremoniously dumped inside the 3 riverbodies of Chennai- Cooum River, Adayar River, and Buckingham canal. Cooum River flows through the commercial and industrial areas of Chennai, collecting 750MT of solid waste every day. The river banks of Cooum are home to 16000 encroachments and slums that bear the brunt of the city’s negligence towards Cooum.
