It is expected to comply with the prescribed norms for biological oxygen demand (BOD) and total suspended solids (TSS). The treated wastewater from NarwaPahar STP is likely discharged into a local stream or river that eventually drains into the Subarnarekha River basin. The Subarnarekha River flows through Jharkhand, West Bengal, and Odisha before emptying into the Bay of Bengal. The plant plays a role in protecting the local water quality and downstream ecosystems, including the Subarnarekha estuary and coastal areas.

The plant is located in the Subarnarekha River basin, which drains into the Bay of Bengal. The Subarnarekha River supports diverse aquatic life and is used for irrigation and drinking water downstream. The region's monsoon climate can lead to seasonal variations in river flow, affecting dilution capacity. The plant's discharge contributes to the overall water quality in the basin, which is important for both ecological health and human use.
