Kalanur Wastewater Treatment Plant, Kalanaur, Haryana, India

The Kalanur wastewater treatment plant is located in Kalanaur, Rohtak district, Haryana, India. It serves a population of about 9,092, classifying it as a small-scale municipal facility within the state's wastewater infrastructure. As a plant in India, it operates under the national regulatory framework of the Central Pollution Control Board (CPCB) and the Haryana State Pollution Control Board (HSPCB). For small agglomerations, primary or secondary treatment is typically required, with standards set under the Environment (Protection) Act, 1986. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Yamuna River basin, a major tributary of the Ganges. The plant plays a role in protecting downstream water quality in this densely populated and agriculturally active region.

The plant is located inland in Haryana, within the Yamuna River basin. The Yamuna flows through the state and joins the Ganges in Uttar Pradesh, eventually reaching the Bay of Bengal. The region supports intensive agriculture and urban settlements, making wastewater treatment crucial for preventing nutrient and pathogen pollution in the river system.
