STP Sarkaghat Distt Mandi zone C - Wastewater Treatment Plant in Sarkaghat, Himachal Pradesh

STP Sarkaghat Distt Mandi zone C is a wastewater treatment plant located in Sarkaghat, a town in the Mandi district of Himachal Pradesh, India. The plant was designed to serve a population of 11,158, placing it in the small to medium agglomeration category for Indian treatment facilities. The plant is currently non-operational. In India, wastewater treatment plants of this scale typically fall under the regulatory framework of the Central Pollution Control Board (CPCB) and state pollution control boards, which mandate secondary treatment standards for municipal wastewater. Standard practices for similar plants include activated sludge or sequencing batch reactor technologies. The plant is located inland, more than 50 km from the coast, and its treated effluent would likely discharge into local rivers or streams that drain into the Beas River basin, a major tributary of the Indus River system. The region is ecologically sensitive, supporting diverse aquatic life and providing water for agriculture and domestic use downstream.

The plant is situated in the Beas River basin, which flows through Himachal Pradesh and Punjab before joining the Sutlej River in Pakistan. The Beas River supports a rich ecosystem, including the endangered Indus river dolphin and various fish species. The plant's non-operational status may pose risks to local water quality, as untreated sewage could enter nearby streams, affecting downstream communities and biodiversity.
