STP Keylong phase III is a wastewater treatment plant located in Keylang, in the Lahaul and Spiti district of Himachal Pradesh, India. The plant serves a small population of 306 people and has a designed capacity of 215 m³/day. The plant provides primary treatment, which involves physical processes like sedimentation to remove settleable solids. As a non-operational facility, it is not currently treating wastewater. In India, wastewater treatment for small communities is governed by state pollution control boards under the Water (Prevention and Control of Pollution) Act, 1974, which mandates treatment before discharge. The plant is situated in the high-altitude Himalayan region, where the local watershed drains into the Chenab River basin. The area's rivers ultimately flow into the Indus River system, supporting downstream ecosystems in the trans-Himalayan region.
Environmental context
The plant is located in the Lahaul Valley, part of the Chenab River basin in the Indian Himalayas. The local watershed drains into the Chenab River, which flows into the Indus River in Pakistan. This high-altitude region supports fragile alpine ecosystems, and untreated wastewater could impact water quality and aquatic life in downstream rivers.
