Gurgaon: GMDA has renewed efforts to construct the city's first compressed biogas (CBG) plant.
The move is part of a major sewage infrastructure upgrade at Dhanwapur more than a year after GMDA's initial tendering attempt failed to secure a competent agency for the project.

The Rs 166-crore project includes the construction of a 100 million litres per day (MLD) sewage treatment plant (STP) based on sequencing batch reactor (SBR) technology, a 100 MLD main pumping station (MPS), and an integrated CBG unit.
GMDA has already floated a fresh tender for the project and if the authority has its way, the facility is expected to be ready by the month of Dec in 2027.
The broader strategy is to prevent untreated sewage discharge into the Najafgarh drain.
The authority floated the tender in Feb last year, but after 13 extensions and no eligible bidders despite participation from eight agencies, the authority finally cancelled the process in Dec 2024.
The plan is now back on track with GMDA officials pushing for timely implementation.
Officials said the earlier plan included a 200 MLD MPS, but the scope was revised after 100 MLD capacity was separately accommodated under the ongoing augmentation of the MPS in Sector 9A.
"The revised scope has now been floated for bidding. We aim to complete the project by Dec 2027," a senior GMDA official said.
The new facility will increase the capacity of the Dhanwapur STP from 218 MLD to 318 MLD, addressing the growing sewage load from sectors 1–23, 33–37 and nearby villages such as Dundahera, Mullahera and Carterpuri.
Currently, the plant is running near capacity, treating about 215 MLD of sewage daily.

The advanced SBR-based plant will ensure high-quality treated water, compliant with National Green Tribunal (NGT) norms.
The treated water will be reused for horticulture and other non-potable purposes, contributing to environmental sustainability.
Additionally, the integrated CBG plant will convert bio-sludge into renewable fuel, with the capacity to generate up to 5,000 cubic metres of biogas per day.
This gas can be supplied to city gas distribution networks, promoting a circular waste-to-energy model, the official added.
The new 100 MLD STP plant at Dhanwapur, once operational, will also treat sewage from new sectors, including 81 to 104, helping reduce pollution in the drainage network and downstream water bodies.
"This project integrates modern sewage treatment with clean energy generation and is part of GMDA's push for sustainable urban infrastructure," the official added.
In addition to this expansion, GMDA is also upgrading the existing 100 MLD STP at Dhanwapur into a tertiary treatment plant to ensure compliance with wastewater discharge norms.
The govt approved this upgrade in July last year and the work was allotted to the agency in July last month.
The Rs 51.3 crore project will take at least two years to complete.
