Earlier this month, the Gurgaon Metropolitan Development Authority (GMDA) approved a significant sewage infrastructure project in Behrampur valued at INR 191 crore. The initiative will introduce a 100 MLD sewage treatment plant (STP) alongside a 400 MLD main pumping station, in response to mounting waste load from newly developed sectors. Existing sewer lines have partly been laid, with the remainder to be completed soon. The project also includes efforts to upgrade water treatment standards and reduce environmental hazards linked to untreated discharge.
After years of delay following its approval, GMDA has finally progressed with construction of a 100 MLD sewage treatment plant and a 400 MLD pumping station in Behrampur, intended to mitigate the rising volume of urban sewage from Gurgaon's expanding sectors. The project was initially sanctioned some time ago, and GMDA recently invited bids to execute the work. Currently, about 23 km of master sewer lines in Sectors 58 to 67 have already been installed by Haryana Shahari Vikas Pradhikaran (HSVP), while remaining pipeline work between Sectors 58 and 76 will be handled by the metropolitan authority.
Once the network is fully connected, the inflow to the treatment plant is expected to surge, requiring an additional 100 MLD capacity. In addition to expanding capacity, the scheme includes a biogas-powered unit to help offset ongoing operating costs. The authority anticipates completing the works within two years.
At present, Behrampur's sewage treatment infrastructure stands at a capacity of 170 MLD, although only about 30 per cent of treated water attains tertiary quality. To address this, GMDA plans to upgrade an existing 120 MLD plant to tertiary treatment standards, reducing biological oxygen demand (BOD) levels from 30 mg/L to 10 mg/L, and making the effluent suitable for reuse in agriculture, construction, and groundwater recharge.
Local residents have raised concerns that new sectors were licensed before adequate infrastructure was in place. Without sewer connectivity, untreated sewage has been discharged openly into drains and vacant plots, producing strong odours, attracting mosquitoes, and posing environmental and health risks. Some have urged GMDA to prioritise completion of the sewer network to prevent further degradation of the area.
By expanding treatment capacity, improving water quality, and integrating renewable energy sources, the authority intends not only to manage current loads but also to anticipate future increases. However, timely execution and network completion will be crucial to prevent untreated discharge from persisting as a public health and environmental hazard. If delivered within the projected timeline, the plan could transform wastewater management in Gurgaon's fast-growing zones and restore environmental balance.
