Chikamagalur Wastewater Treatment Plant, Chikkamagaluru, Karnataka

The Chikamagalur wastewater treatment plant is located in Hosamane Badavane, Chikkamagaluru, Karnataka, India. Currently under construction, it is designed to serve a population of around 138,000, making it a medium-to-large agglomeration for the region. The plant will be a key component of the city's sanitation infrastructure, addressing the wastewater needs of this growing urban center in the Western Ghats foothills. As a facility under construction, specific treatment processes and capacity details are not yet finalized. However, Indian wastewater treatment plants of this scale typically employ secondary treatment technologies such as activated sludge or sequencing batch reactors, in compliance with the Central Pollution Control Board (CPCB) standards. The plant is expected to meet the effluent discharge norms set by the Karnataka State Pollution Control Board (KSPCB) for inland surface waters. The treated wastewater from the plant will likely be discharged into local streams that drain into the Bhadra River, a tributary of the Tungabhadra River, which ultimately flows into the Krishna River and the Bay of Bengal. The region is ecologically sensitive due to its proximity to the Western Ghats, a biodiversity hotspot, and the plant's operation will help protect downstream water quality and aquatic ecosystems.

The plant is situated in the Western Ghats foothills, a UNESCO World Heritage site and biodiversity hotspot. Treated effluent will likely enter local streams feeding the Bhadra River, part of the Krishna River basin, which drains into the Bay of Bengal. The region supports diverse aquatic life and is important for migratory species. Proper treatment is critical to prevent nutrient loading and protect downstream ecosystems.
