Tanajiwadi Wastewater Treatment Plant, Pimpri-Chinchwad, Maharashtra

Tanajiwadi is a wastewater treatment plant located in Pimple Nilakh, Pimpri-Chinchwad, in the Pune district of Maharashtra, India. The plant serves a population of about 113,580, placing it in the medium-to-large agglomeration category for Indian urban centers. It is part of the municipal infrastructure managed by the local authorities. India's wastewater treatment regulations are governed by the Central Pollution Control Board (CPCB) under the Water (Prevention and Control of Pollution) Act, 1974. Plants of this scale are typically required to meet secondary treatment standards before discharge. The plant is operational, contributing to the region's sanitation and water quality management. The treated effluent from Tanajiwadi likely discharges into local water bodies that drain into the Mula-Mutha river system, which flows through Pune and ultimately joins the Bhima River, a tributary of the Krishna River. This river system supports diverse aquatic life and is crucial for irrigation and drinking water downstream. The plant plays a key role in reducing pollution loads in this ecologically important watershed.

The plant's treated effluent enters the Mula-Mutha river system, which flows through Pune and joins the Bhima River, a major tributary of the Krishna River. The Krishna River basin supports extensive agriculture and provides drinking water to millions. The plant helps protect downstream water quality, reducing nutrient and pathogen loads that could harm aquatic ecosystems and public health.
