With a designed capacity of 946.35 thousand gallons per day and an actual discharge volume of 870.65 thousand gallons per day, the facility operates at a high utilization rate. This indicates that the plant is effectively managing the wastewater generated by the community. The treated effluent is discharged into a local water body, likely a stream or river within the Mississippi River basin, as Preston is located in eastern Iowa near the Mississippi River. The plant's discharge contributes to the overall water quality of the region, supporting downstream aquatic ecosystems and recreational uses.

The plant discharges into a local waterway that ultimately drains into the Mississippi River, a major river system that flows into the Gulf of Mexico. The Mississippi River basin supports diverse aquatic life and is an important migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this ecologically significant watershed.
