Overview
Raipur Kalan Chandigarh is an operational wastewater treatment plant in Raipur Khurd, Chandigarh, India, serving approximately 86,000 people. It plays a key role in managing municipal wastewater in the region.
Raipur Kalan Chandigarh is an operational wastewater treatment plant located in Raipur Khurd, Chandigarh, India. Serving a population of around 86,000, it is a medium-to-large agglomeration facility that supports the sanitation needs of this urban area. The plant is situated in the union territory of Chandigarh, a planned city known for its high standards of urban infrastructure. Under India's regulatory framework, wastewater treatment plants serving populations over 50,000 are expected to meet secondary treatment standards as per the Central Pollution Control Board (CPCB) guidelines. As a facility of this scale, it likely incorporates biological treatment stages to reduce organic load and suspended solids before discharge. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Ghaggar River system, which flows through northern India into Pakistan. The Ghaggar River is a seasonal river that supports agriculture and groundwater recharge in the region. Proper treatment at this plant helps protect downstream water quality and reduces pollution in the sensitive semi-arid ecosystem of the Ghaggar basin.
Environmental context
The plant's treated effluent enters local drains that feed into the Ghaggar River, a seasonal river system that flows through Haryana and Punjab before crossing into Pakistan. The Ghaggar basin supports intensive agriculture and is a critical water source for irrigation. Downstream, the river eventually reaches the Thar Desert region, where water quality is vital for both human use and ecological balance. Effective wastewater treatment at this plant helps prevent nutrient loading and contamination in this water-stressed region.
Frequently asked questions
The plant is located on Dakshin Marg in the Reserved Area of Raipur Khurd, Chandigarh, India, with coordinates 30.681 N, 76.822 E.
The plant serves approximately 86,011 people, classifying it as a medium-to-large agglomeration under Indian wastewater management standards.
The treated effluent is discharged into local drains that eventually flow into the Ghaggar River system, which is a seasonal river supporting agriculture in northern India.
The plant operates under India's Water (Prevention and Control of Pollution) Act, 1974, and follows Central Pollution Control Board (CPCB) standards, which mandate secondary treatment for facilities serving over 50,000 people.
For agglomerations of this size, Indian regulations typically require secondary treatment, often using activated sludge or similar biological processes, to reduce BOD and suspended solids before discharge.
