The work is expected to be completed over the next two to two-and-a-half years. New Delhi: The national capital is set to get a new network of sewage treatment plants and sewer lines under a Rs 8,941-crore plan aimed at stopping untreated wastewater from entering the Yamuna. Union Home Minister Amit Shah will inaugurate and lay the foundation stones for 43 projects on Thursday (October 22).
The plan includes unauthorised colonies and villages on the outskirts of the capital, where smaller treatment plants will handle wastewater close to where it is generated.
Delhi Water Minister Parvesh Verma said the projects would increase sewage treatment capacity across residential areas that presently lack adequate infrastructure.
A new STP with a capacity of 124 million gallons per day (MGD) will be built at Okhla at a cost of Rs 1,161 crore.
It will be Delhi’s largest sewage treatment plant and will be jointly developed by the Centre and the Delhi government, according to the project plan. Verma said that the aim was to stop untreated sewage from reaching the Yamuna through Delhi’s drains once the projects are complete.
The plan aims to collect, treat and reuse wastewater through 43 projects to prevent untreated sewage from entering the Yamuna.
“Over the next two to two-and-a-half years, when all these works are completed, no untreated sewage from Delhi will flow into drains and, through them, into the Yamuna river,” he said. He said that the long-term solution was to collect and treat sewage before it entered the river.
