PERU WWTP is a municipal wastewater treatment facility located in Peru, Illinois, a city in LaSalle County. Serving a population of around 22,806, the plant is part of the region's essential water infrastructure, managing domestic wastewater from the community. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the U.S. Clean Water Act, which mandates biological treatment to reduce organic pollutants. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Illinois Environmental Protection Agency, ensuring discharges comply with water quality standards. The treated effluent is discharged into the Illinois River watershed, which flows into the Mississippi River and ultimately to the Gulf of Mexico. This downstream connection highlights the plant's role in protecting the Illinois River ecosystem and contributing to the health of the larger Mississippi River basin, which supports diverse aquatic life and provides drinking water for millions.
Environmental context
The plant discharges into the Illinois River, a major tributary of the Mississippi River. The Illinois River watershed supports diverse aquatic habitats, including wetlands and backwater lakes, and is an important migratory corridor for waterfowl and fish species. Downstream, the Mississippi River carries the effluent to the Gulf of Mexico, where nutrient loading can contribute to hypoxic zones. Effective treatment at PERU WWTP helps mitigate these regional impacts.
