Scranton WWTP - Secondary Treatment Plant in Greene County, Iowa

Scranton WWTP is a municipal wastewater treatment facility located in Scranton Township, Greene County, Iowa. It serves a small population of 557 residents, providing secondary treatment to remove organic matter and suspended solids from domestic wastewater. The plant is situated in a rural agricultural region of central Iowa. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. With a designed capacity of 227.12 million gallons per day and an average discharge volume of 238.48 million gallons per day, the facility manages local wastewater within its operational scope. As a small agglomeration, it meets the national standards for effluent quality set by the EPA and enforced by the Iowa Department of Natural Resources. The treated effluent is discharged into nearby streams that drain into the Raccoon River watershed, which flows into the Des Moines River and ultimately the Mississippi River. This waterway supports diverse aquatic life and provides water for downstream communities and agriculture. The plant's location inland, away from coastal areas, reduces direct marine impact but emphasizes the importance of protecting freshwater ecosystems.

The plant discharges into local tributaries of the Raccoon River, which flows into the Des Moines River and then the Mississippi River. This watershed supports a variety of fish and aquatic species and is used for recreation and drinking water supply. The surrounding agricultural land use means nutrient management is critical to prevent eutrophication in downstream water bodies.
