The plant's treated effluent likely discharges into the Mula-Mutha river system, which flows through Pune and eventually joins the Bhima River, a tributary of the Krishna River. The Krishna River drains into the Bay of Bengal. The plant plays a critical role in protecting these water bodies from untreated sewage, supporting aquatic life and downstream water quality.

Bahiroba plant's treated wastewater likely enters the Mula-Mutha river system, which flows through Pune and joins the Bhima River, a tributary of the Krishna River. The Krishna River ultimately empties into the Bay of Bengal. This watershed supports diverse aquatic ecosystems and provides water for agriculture and domestic use downstream. Effective treatment is essential to prevent eutrophication and protect biodiversity in these rivers.
