Nayandanahalli I is an operational wastewater treatment plant located in the BEML Layout 7th Phase, Mylasandra, Bengaluru, Karnataka, India. It serves a population of approximately 86,300 people, making it a medium-sized facility within the urban agglomeration of Bengaluru. The plant is part of the city's municipal wastewater infrastructure, managed by the Bengaluru West City Corporation. As a plant serving a population between 10,000 and 100,000, it falls under India's regulatory framework for sewage treatment. Under the National Green Tribunal (NGT) and Central Pollution Control Board (CPCB) guidelines, such facilities are expected to meet secondary treatment standards at a minimum, with many moving toward tertiary treatment for water reuse. The plant's operational status indicates it is actively contributing to the region's wastewater management. The treated effluent from Nayandanahalli I likely discharges into local water bodies that drain into the Arkavathi River, a tributary of the Kaveri River. The Kaveri basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and drinking. The plant plays a crucial role in protecting downstream water quality in this sensitive river system.
Environmental context
The plant is situated in the Kaveri River basin, with treated effluent likely flowing into the Arkavathi River, a major tributary of the Kaveri. The Kaveri River supports a rich diversity of aquatic species and is a critical water source for irrigation and domestic use in Karnataka and Tamil Nadu. Protecting this watershed from untreated sewage is essential for maintaining water quality and ecological balance in the downstream Cauvery Delta.
