MILES WWTP - Miles, Iowa Wastewater Treatment Plant

MILES WWTP is a municipal wastewater treatment facility located in Miles, Iowa, a small community in Jackson County. The plant serves a population of approximately 445 residents, reflecting its role as a local infrastructure asset for this rural Midwestern town. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 189.27 cubic meters per day and a similar discharge volume, the plant operates at full capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent from MILES WWTP is discharged into local waterways that ultimately drain to the Mississippi River basin. The plant plays a key role in protecting downstream aquatic ecosystems by reducing organic pollutants and solids before discharge, supporting the ecological health of the region's rivers and streams.

MILES WWTP discharges into a tributary of the Mississippi River, which flows south to the Gulf of Mexico. The local watershed supports diverse aquatic life and is part of a larger river system that provides habitat for fish and migratory birds. The plant's secondary treatment helps reduce nutrient loading, which is critical for mitigating hypoxia in the Gulf of Mexico.
