West Chester WWTP is a municipal wastewater treatment facility located in West Chester, Iowa, United States. The plant serves a small population of 159 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 75.71 million gallons per day, the facility is sized to handle the wastewater generated by the local population. The treated effluent is discharged into nearby waterways, ultimately contributing to the Mississippi River basin. This region supports diverse aquatic life and is important for downstream water quality. The plant's operations help protect local streams and rivers from pollution, maintaining ecological balance in the area.

The plant discharges into local streams that flow into the Iowa River, a tributary of the Mississippi River. The Mississippi River basin is a major ecological corridor supporting fish, birds, and other wildlife. Protecting water quality in this watershed is crucial for downstream ecosystems, including the Gulf of Mexico, where nutrient pollution can cause hypoxic zones.
