STP Hamirpur Distt Hamirpur Zone III - Secondary Treatment Plant in Hamirpur, Himachal Pradesh

STP Hamirpur Distt Hamirpur Zone III is a municipal wastewater treatment facility located in Anu, Hamirpur, Himachal Pradesh, India. The plant serves a population of 4,543 and operates with a designed capacity of 680 m³/day, treating wastewater to secondary level. As a small-scale facility, it plays a key role in managing domestic sewage for the local community. The plant employs secondary treatment processes, which typically involve biological treatment to reduce organic matter and suspended solids. In India, such plants are regulated under the Water (Prevention and Control of Pollution) Act, 1974, and must comply with effluent standards set by the Central Pollution Control Board (CPCB). For small agglomerations, secondary treatment is the standard requirement to protect water quality. The treated effluent is discharged into local streams or rivers that eventually drain into the Beas River basin, a major tributary of the Indus River system. The Beas River supports diverse aquatic life and is an important water source for irrigation and drinking in the region. The plant's operation helps reduce pollution loads in these downstream waters.

The plant discharges into local water bodies that flow into the Beas River, a key tributary of the Indus River system. The Beas River supports a rich ecosystem, including fish species and migratory birds, and provides water for agriculture and domestic use in Himachal Pradesh and Punjab. Protecting this watershed from untreated sewage is critical for maintaining water quality and ecological health.
