Overview
Chikali Phase II is an operational wastewater treatment plant in Pimpri-Chinchwad, Maharashtra, India, serving approximately 106,899 people. It plays a key role in managing municipal wastewater in the Pune metropolitan region.
Chikali Phase II is an operational wastewater treatment plant located in Sudershan Nagar, Pimpri-Chinchwad, in the Pune district of Maharashtra, India. The plant serves a population of around 106,899, placing it in the category of a medium-to-large agglomeration under Indian urban wastewater management standards. As a facility in India, Chikali Phase II operates under the national regulatory framework governed by the Central Pollution Control Board (CPCB) and the Maharashtra Pollution Control Board (MPCB). For agglomerations of this scale, Indian standards typically require secondary treatment followed by disinfection, with effluent standards aligned to the Environment (Protection) Rules. It is expected to meet the prescribed norms for biological oxygen demand (BOD) and total suspended solids (TSS) before discharge. The treated wastewater from Chikali Phase II likely discharges into a local watercourse that eventually drains into the Mula-Mutha River system, which flows through Pune and ultimately joins the Bhima River, a tributary of the Krishna River. The Krishna River basin supports diverse aquatic life and is a critical water resource for agriculture and domestic use in western India. Proper treatment at this plant helps protect downstream water quality and public health.
Environmental context
The plant's treated effluent is expected to enter the Mula-Mutha River system, which flows through the Pune urban area and joins the Bhima River. The Bhima River is a major tributary of the Krishna River, which drains into the Bay of Bengal. The Krishna basin supports a rich diversity of fish and other aquatic species and is vital for irrigation and drinking water supply. Effective wastewater treatment at Chikali Phase II is essential to prevent nutrient loading and pathogen contamination in this ecologically and economically important river system.
