WSP Technology Sewage Treatment Plant Bhavani Municipality, Chithode, Tamil Nadu

The WSP Technology Sewage Treatment Plant Bhavani Municipality is an under-construction facility located in Chithode, Erode district, Tamil Nadu, India. Designed to serve a population of 26,324, the plant will address municipal wastewater treatment needs in this growing urban area. As a facility under construction, specific treatment processes and capacity details are not yet finalized. In India, sewage treatment plants of this scale typically employ technologies such as activated sludge process, sequencing batch reactors, or waste stabilization ponds, in compliance with the Central Pollution Control Board (CPCB) norms. The plant will be required to meet effluent standards for discharge into inland surface waters. The treated effluent is expected to be discharged into the Bhavani River, a tributary of the Kaveri River, which flows through Tamil Nadu and ultimately drains into the Bay of Bengal. The Bhavani River supports irrigation and drinking water needs downstream, making proper treatment essential for public health and aquatic ecosystem preservation.

The plant will discharge into the Bhavani River, a key tributary of the Kaveri River system. The Kaveri basin supports diverse aquatic life and provides water for agriculture and domestic use across Tamil Nadu. Downstream, the river reaches the Bay of Bengal, where nutrient loading from untreated wastewater can contribute to eutrophication and coastal ecosystem degradation. Effective treatment at this plant will help protect the Bhavani River's water quality and the ecological health of the Kaveri delta.
