IBERIA WWTP - Secondary Treatment Plant in Iberia, Missouri

IBERIA WWTP is a municipal wastewater treatment facility located in Iberia, Miller County, Missouri. The plant serves a small community of 736 residents and operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 567.81 cubic meters per day and an average discharge volume of 264.98 cubic meters per day, the facility operates well within its capacity. As a small inland plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local receiving water body, likely a stream or river within the Missouri River basin. The plant's location in central Missouri places it within a region of agricultural and rural land use, where maintaining water quality is important for downstream ecosystems and recreational uses.

The plant discharges into a local waterway that ultimately drains into the Missouri River, a major tributary of the Mississippi River. This watershed supports diverse aquatic life and provides habitat for fish and migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream water quality in the Missouri River basin.
