Mattagajpur Wastewater Treatment Plant, Cuttack, Odisha, India

Mattagajpur is a wastewater treatment plant currently under construction in Cuttack, Odisha, India. Located on Canal Road in the Khapuria area, the facility is designed to serve a population of 106,899, making it a medium-to-large agglomeration under Indian urban wastewater standards. The plant is part of Cuttack's municipal infrastructure, addressing the city's growing sanitation needs. As an under-construction facility, specific treatment processes and capacity details are not yet finalized. However, Indian wastewater treatment plants of this scale typically employ secondary biological treatment (such as activated sludge or sequencing batch reactors) to meet the effluent standards set by the Central Pollution Control Board (CPCB) under the Water (Prevention and Control of Pollution) Act, 1974. The plant is expected to comply with national discharge norms for inland surface waters. The treated effluent will likely be discharged into local canals or rivers within the Mahanadi River basin, which ultimately drains into the Bay of Bengal. The Mahanadi delta supports diverse aquatic life and is an important ecological zone for fisheries and agriculture. Proper treatment at Mattagajpur will help reduce pollution loads in this sensitive downstream environment.

The plant is situated in the Mahanadi River basin, one of India's major east-flowing rivers. The Mahanadi originates in Chhattisgarh and flows through Odisha, forming a large delta before emptying into the Bay of Bengal. The delta region supports extensive rice paddies, mangrove forests, and estuarine ecosystems that are critical for biodiversity, including several fish species and migratory birds. Effective wastewater treatment at Mattagajpur is essential to prevent nutrient and pathogen pollution from reaching these ecologically sensitive downstream waters.
