For a plant of this scale, secondary treatment is typically required, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant's treated effluent discharges into the local watershed, which is part of the Ohio River basin. The Ohio River flows into the Mississippi River and ultimately reaches the Gulf of Mexico. This downstream connection highlights the plant's role in protecting water quality across a large regional drainage system.

MEADVILLE STP discharges into the French Creek watershed, a tributary of the Allegheny River, which flows into the Ohio River and then the Mississippi River to the Gulf of Mexico. French Creek is known for its high aquatic biodiversity, supporting species such as the eastern hellbender and various freshwater mussels. The plant's operations are critical to maintaining water quality in this ecologically sensitive stream.
