It is situated inland, more than 50 kilometers from the Atlantic coast, and discharges into the local watershed. As a US-based plant serving over 100,000 people, Tonawanda T WWTP is subject to the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act.

Plants of this scale typically employ secondary treatment as a minimum, with potential advanced treatment depending on permit conditions. The plant's treated effluent flows into the Niagara River watershed, which drains into Lake Ontario and eventually the St. Lawrence River and Atlantic Ocean. The facility plays a critical role in protecting the ecological health of the Niagara River and Lake Ontario, supporting aquatic life and recreational uses downstream.

Tonawanda T WWTP discharges into the Niagara River, which flows north from Lake Erie to Lake Ontario. The Niagara River supports diverse aquatic ecosystems, including fish spawning grounds and migratory bird habitats. Downstream, Lake Ontario is a major freshwater resource that provides drinking water and supports fisheries. The plant's operations help maintain water quality in this interconnected system, reducing nutrient and pollutant loads that could otherwise contribute to eutrophication and harm aquatic life.
