NDMC to Build 8 Sewage Treatment Plants, Recycled Water to Maintain Delhi’s Green Cover.

The New Delhi Municipal Council has issued a Request for Proposal (RFP) to set up eight decentralised sewage treatment plants (STPs) under a public-private partnership (PPP) model, aiming to reuse treated water for horticulture, fountains, and water bodies across the city. The initiative is expected to reduce dependence on freshwater for maintaining Delhi’s green cover.

The proposed STPs, with capacities ranging from 500 to 1,000 kilolitres per day (KLD), will be located at key sites including Shanti Path, Lodhi Garden, Sanjay Lake Park, and Talkatora Garden. Officials said the treated sewage water will be used to maintain NDMC’s green cover amid limited freshwater availability.

The civic body has set 15 April as the last date for bid submissions, with a pre-bid meeting scheduled for 1 April. Selected private developers will execute, operate, and maintain the STPs for a 12-year period.

The tender does not specify a fixed project cost, requiring bidders to propose their own financial models. An initial security deposit of ₹10 lakh and a performance security of ₹40 lakh are mandated. The concessionaire will be selected based on the lowest “treated water rate” quoted during competitive bidding.

Catering to around 3.5 lakh residents and nearly 15 lakh daily visitors, NDMC expects the project to conserve water and strengthen environmental sustainability in the national capital.
