Meherpalli Wastewater Treatment Plant, Bhubaneswar, Odisha, India

Meherpalli is a wastewater treatment plant currently under construction in Ward 15 of the South West Zone, Bhubaneswar Municipal Corporation, Odisha, India. The plant is designed to serve a population of 374,147, making it a large-scale municipal facility for the region. Its location in the rapidly growing city of Bhubaneswar underscores the need for expanded sanitation infrastructure. As a plant under construction, specific treatment processes and capacity details are not yet finalized. However, under India's National Mission for Clean Ganga and the Odisha State Pollution Control Board regulations, large municipal plants like this are expected to meet secondary treatment standards at minimum, with provisions for tertiary treatment where required for environmental sensitivity. The plant's scale places it in the category of major urban wastewater infrastructure. The plant will discharge treated wastewater into local water bodies that ultimately drain into the Bay of Bengal via the Mahanadi River delta system. The region's coastal ecology and the Chilika Lake ecosystem downstream depend on effective wastewater management to prevent nutrient loading and maintain water quality. The plant's operation will be critical for protecting these sensitive aquatic environments.

The plant lies within the Mahanadi River basin, which drains into the Bay of Bengal through a vast delta system. Downstream, the waters feed the Chilika Lake, a brackish lagoon of high ecological importance that supports diverse aquatic life and migratory birds. Effective treatment at Meherpalli will help reduce nutrient and pathogen loads entering this sensitive coastal ecosystem.
