Adampool Wastewater Treatment Plant, Gangtok, Sikkim, India

Adampool wastewater treatment plant is located in Gangtok, the capital city of Sikkim, India, along the Rannipool-Rumtek-Sirwani Road. The plant serves a population of approximately 53,450 people, making it a medium-sized facility for the region. It operates under India's environmental regulations, which mandate treatment standards for municipal wastewater. However, as a facility serving a medium agglomeration in India, it is expected to comply with the Central Pollution Control Board (CPCB) norms, which typically require secondary treatment or equivalent for such scales. The plant is operational and contributes to the local sanitation infrastructure. The treated effluent from Adampool likely discharges into a local watercourse that eventually feeds into the Teesta River, a major river in Sikkim. The Teesta River flows south through West Bengal and joins the Brahmaputra River in Bangladesh, ultimately reaching the Bay of Bengal. The plant plays a role in protecting the downstream aquatic ecosystem and water quality in the Teesta basin.

Adampool plant is situated in the Himalayan foothills, within the Teesta River basin. The Teesta River originates in the Himalayas and flows through Sikkim and West Bengal before joining the Brahmaputra in Bangladesh. The river supports diverse aquatic life and is ecologically sensitive due to its mountainous terrain and seasonal flow variations. The plant's discharge affects downstream water quality, including areas used for irrigation and drinking water.
