Union Secretary Inspects Chennai’s Waste Management Sites
Union Housing and Urban Affairs Secretary Satendra Singh inspected four Greater Chennai Corporation facilities on Saturday, including a biogas plant, a tertiary sewage treatment plant, an electric vehicle maintenance workshop, and the Kodungaiyur dump yard. The visits were attended by Additional Chief Secretary Gagandeep Singh Bedi of the Municipal Administration and Water Supply Department.
At the Chetpet biogas plant, a public‑private partnership, Singh examined the conversion of wet waste into biogas. Chennai produces 6,150 tonnes of waste daily, of which about 3,200 tonnes are biodegradable, 2,950 tonnes are non‑biodegradable, and the remainder is road silt. The plant can process 140 tonnes of wet waste per day and currently handles roughly 120 to 140 tonnes supplied by the GCC.
He then inspected the Koyambedu tertiary treatment plant, which uses reverse osmosis technology. The facility has a capacity of 45 million litres per day, and two such units together treat 90 million litres of wastewater daily to support the city’s water security and reuse.
Singh also visited the maintenance and charging workshop for electric three‑wheelers used for garbage collection.
At the Kodungaiyur dump yard, he reviewed biomining operations. The 333‑acre site contains waste on more than 252 acres. A ₹641‑crore project to excavate and remove legacy waste is divided into six packages, and six acres have been reclaimed to date. GCC officials and representatives from the Chennai Metropolitan Water Supply and Sewerage Board also participated in the inspections.
