Gurugram Water and Sewer: GMDA vs MCG and What Buyers Should Check

Buyers compare price, metro access and schools, but in Gurugram the most common complaint after possession is often water. Supply varies sharply by sector, and two agencies, the Gurugram Metropolitan Development Authority (GMDA) and the Municipal Corporation of Gurugram (MCG), share responsibilities in ways that confuse residents. This guide sets out what recent reporting shows and how to check before you pay.

Supply and demand: the headline numbers

A June 2026 Newslaundry report cites GMDA treatment capacity of 670 MLD against projected demand of 874.3 MLD, a delayed fourth treatment unit that would add 100 MLD and that had missed three deadlines since June 2024, and groundwater extraction at 326.52% of natural replenishment. It also reports the water table down 82% since the 2008 'dark zone' declaration.

An earlier Tribune report on GMDA's enforcement against use of drinking water for construction gave a smaller supply picture, with treatment plants at Basai and Chandu Budhera and a gap with demand covered by around 600 borewells. The two reports are from different periods and use different figures, so treat the direction as clearer than any single number.

Who is responsible for what

GMDA operates the bulk water treatment and trunk network. Municipal bodies, including MCG, handle local distribution and sewer lines within their limits, and Manesar has its own municipal corporation. In practice, the boundary is blurred: when sewage pooled in vacant plots in Sector 37-C in May 2023, the Tribune report named MCG, the Manesar municipal corporation and GMDA as responsible bodies, and a GMDA CEO said complaints were being looked into. Before relying on a helpline, ask which agency is the one that actually serves the sector and the society.

Where reported shortfalls are

Newslaundry lists 12 tail-end areas with chronic shortfalls: Sectors 21, 22, 23, 54, 55, 57, 59, 63, 63A, 70, 95 and Dundahera village. It reports that water arrives once every three days in Dundahera and once in four days in Sushant Lok 2, that only about 60 of 100 households receive water in summer in Sector 55 and that tubewell-fed boosters operate at Dundahera, Sushant Lok 3, Sector 55, 56 and 22B. Tanker prices cited are ₹1,000-1,500 for 5,000 litres in summer, with a monthly household cost of ₹8,400-26,000 for three tankers a week.

The Tribune's earlier report lists 12A, Gurgaon Village, Sectors 21-23, 23A, Dundahera, Surya Vihar, Sectors 55-57, DLF Phases 1-2, old Gurugram, Sushant Lok and Malibu Town among affected areas. These are reports of specific periods; conditions may have changed. The point for buyers is that an established address does not guarantee reliable supply.

Sewage treatment in societies

Housing societies that generate sewage are expected to treat it. In 2019 GMDA issued notices to 366 societies to install sewage treatment plants or lose sewerage connections, noting that developers had given STP undertakings when seeking licences but most had not fulfilled them. The Tribune's 2023 report on Sector 37-C quoted the United Association of New Gurugram saying most societies lack optimum STP infrastructure and either discharge illegally or use tanker owners. For a buyer, a poorly run STP means smell, pollution risk and potential action against the society.

Groundwater and enforcement

The Tribune reports that using potable water or groundwater for construction is banned and only treated STP water is permitted, yet projects continue to use drinking water. Newslaundry also notes the National Green Tribunal's concerns about illegal groundwater extraction. If your home depends on a borewell, ask how it is permitted and what happens if it fails; Newslaundry reports that Surya Vihar's tubewell failed as groundwater fell.

A buyer's water and sewer checklist

• Ask the society or RWA how many days a week and for how many hours municipal water arrives, and how much the society spent on tankers last summer.
• Request the last two years of water-related maintenance expenses and the tanker bills.
• Ask whether the society is connected to the municipal sewer line or runs its own STP, whether the STP is functioning and who maintains it.
• Visit in May or June, not only in the monsoon.
• Check for water-source disclosures in the project's approvals and, for new projects, the HRERA page; see our how-to-read-a-RERA-page guide.
• Ask neighbours on the same floor and in adjoining blocks, as pressure varies even inside a society.
• Look for rainwater harvesting and recycled-water systems, which indicate planning for shortages.
• Price the cost of backup storage or tankers into your monthly budget.

Where to complain

Complaints on trunk water and sewer typically go to GMDA, and on local lines or garbage to the MCG, though the Sector 37-C report shows ownership may be unclear. Keep dated written complaints; they matter if the issue escalates to HRERA, a consumer forum or a court. For a registered project that promised specific infrastructure, see our HRERA complaint guide.
