Woodburn WWTP - Secondary Treatment Plant in Woodburn, Iowa

Woodburn WWTP is a municipal wastewater treatment facility located in Woodburn, Iowa, serving a small population of 244 residents. The plant is situated in Clarke County and provides essential sanitation services to the local community. The plant employs secondary treatment, which is the standard biological process required by the US Clean Water Act for municipal wastewater. With a designed capacity of 75.71 units, the facility is appropriately scaled for its service area. As a small agglomeration, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into a local receiving water body, which ultimately drains into the Mississippi River basin. This watershed supports diverse aquatic life and provides water resources for downstream communities. The plant's operation helps maintain the ecological health of the region's waterways.

The plant discharges into a local stream that flows into the Des Moines River, a tributary of the Mississippi River. The Mississippi River basin is a major ecological corridor supporting fish, migratory birds, and riparian habitats. The plant's secondary treatment reduces organic pollutants and suspended solids, protecting downstream water quality in this agriculturally intensive region.
