EDINA WWTP - Secondary Wastewater Treatment Plant in Edina, Missouri

EDINA WWTP is a municipal wastewater treatment plant located in Edina, Knox County, Missouri, United States. The facility serves a population of approximately 1,176 residents, reflecting its role as a small-scale treatment system for the local community. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 832.79 volume units and an average daily discharge of 643.52 volume units, the plant operates within its design parameters. As a US facility, it is subject to the Clean Water Act and operates under an NPDES permit issued by the Missouri Department of Natural Resources, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River basin. This watershed supports diverse aquatic life and provides water resources for downstream communities. The plant's secondary treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the receiving waters.

The plant discharges into a local stream that is part of the Mississippi River watershed. The Mississippi River system is a major ecological corridor supporting fish, migratory birds, and other wildlife. Downstream, the river flows into the Gulf of Mexico, where nutrient inputs from upstream sources can contribute to hypoxic zones. The plant's secondary treatment helps mitigate such impacts by reducing organic and nutrient loads.
