The Allegheny River supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps protect water quality in this important river system.

The treated effluent from Freeport Boro STP flows into a local stream that is part of the Allegheny River watershed. The Allegheny River joins the Monongahela River to form the Ohio River, which eventually drains into the Mississippi River and the Gulf of Mexico. The Allegheny River supports a variety of fish species and is an important ecological corridor in western Pennsylvania. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain the river's health for recreation and aquatic habitat.
