Ramalingeswara Nagar Wastewater Treatment Plant, Vijayawada, Andhra Pradesh

Ramalingeswara Nagar wastewater treatment plant is located in the Poornachandra Nagar area of Patamata Lanka, Vijayawada, in the NTR district of Andhra Pradesh, India. The plant serves a population of about 66,812, placing it in the medium agglomeration category for Indian urban wastewater management. As an operational facility, the plant is subject to India's environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the National Green Tribunal directives. For a city of Vijayawada's size, secondary treatment is typically required, with potential nutrient removal for discharge into sensitive water bodies. The treated effluent from the plant ultimately drains into the Krishna River, one of India's major east-flowing rivers, which flows into the Bay of Bengal. The Krishna River supports diverse aquatic life and is a critical water source for irrigation and drinking water in the region. The plant plays a key role in protecting this river from untreated sewage.

The plant's treated effluent discharges into the Krishna River basin, which flows through Andhra Pradesh and empties into the Bay of Bengal. The Krishna River is a major water source for agriculture and domestic use, and its delta supports rich biodiversity. The plant helps reduce nutrient and pathogen loads, protecting downstream ecosystems and coastal waters.
