STP Bhangsunag - Secondary Wastewater Treatment Plant in Bhagsu, Himachal Pradesh

STP Bhangsunag is located in Upper Bhagsu, near McLeod Ganj in Dharamshala, Himachal Pradesh, India. It serves a small community of 1,497 people in the Bhagsu area, a popular tourist destination in the Kangra district. The plant was designed with a capacity of 224 cubic meters per day and a discharge volume of 224 cubic meters per day, but it is currently non-operational. As a secondary treatment facility, STP Bhangsunag would have provided biological treatment to remove organic matter and suspended solids. Under India's environmental regulations, small sewage treatment plants like this are typically governed by the Central Pollution Control Board (CPCB) standards for effluent discharge. The plant's treated wastewater would have discharged into local streams that flow into the Beas River, a major river in Himachal Pradesh that eventually joins the Sutlej River in Punjab. The Beas River supports diverse aquatic life and is an important water source for irrigation and drinking water downstream. The region's mountainous terrain and monsoon climate make proper wastewater treatment critical to prevent contamination of these sensitive water bodies.

STP Bhangsunag is situated in the Himalayan foothills, where its treated effluent would flow into local streams that feed the Beas River. The Beas River is a vital water source for the region, supporting agriculture, drinking water, and biodiversity, including the endangered Indus river dolphin in its lower reaches. The plant's non-operational status poses a risk of untreated sewage entering these waterways, potentially impacting water quality and aquatic ecosystems in the Beas basin.
