Pahari Patna 7 Wastewater Treatment Plant, Patna, Bihar

Pahari Patna 7 is a wastewater treatment plant located in Ranipur, Patna, Bihar, India. It was designed to serve a population of 167,030, placing it in the category of a large agglomeration under Indian urban wastewater management standards. The plant is currently non-operational, which impacts the local wastewater treatment capacity in the Patna area. As a large-scale facility, Pahari Patna 7 would have been expected to provide at least secondary treatment under India's environmental regulations, which are guided by the Water (Prevention and Control of Pollution) Act, 1974. The Central Pollution Control Board (CPCB) sets discharge standards for such plants, requiring compliance with parameters like biochemical oxygen demand (BOD) and total suspended solids (TSS). The plant's non-operational status means that untreated or partially treated wastewater may be entering the local environment. Patna lies on the southern bank of the Ganges River, one of India's most significant rivers. The Ganges flows through Bihar and ultimately drains into the Bay of Bengal. The plant's discharge, if operational, would likely affect the Ganges basin, which supports diverse aquatic life and provides water for millions of people. The non-operational status raises concerns about pollution in this ecologically sensitive river system.

Pahari Patna 7 is located in Patna, Bihar, on the southern bank of the Ganges River. The Ganges flows eastward through Bihar and West Bengal before forming the Ganges-Brahmaputra delta and emptying into the Bay of Bengal. This river system is ecologically significant, supporting a wide range of aquatic species, including the Ganges river dolphin and various fish species. The plant's non-operational status means that untreated sewage may be discharged into the Ganges, contributing to pollution and threatening the river's biodiversity and the health of downstream communities.
