Luxemburg WWTP - Secondary Treatment Facility in Luxemburg, Iowa

Luxemburg WWTP is a municipal wastewater treatment plant located in the small community of Luxemburg, Dubuque County, Iowa. Serving a population of 257, the plant provides secondary treatment to meet state and federal water quality standards. As a secondary treatment facility, the plant uses biological processes to remove organic matter and suspended solids. Its designed capacity is 68.14 million gallons per year, matching the current discharge volume. The plant operates under the U.S. Clean Water Act, which requires NPDES permits for all point source discharges. The treated effluent is discharged into a local stream that flows into the Mississippi River basin. The Mississippi River is a major ecological corridor supporting diverse aquatic life and migratory birds. The plant's location in the Upper Mississippi River watershed means its discharge contributes to the overall water quality of this nationally significant river system.

The plant discharges into a tributary of the Mississippi River, which flows south to the Gulf of Mexico. The Upper Mississippi River supports diverse fish and mussel populations and is an important migratory route for waterfowl. The watershed is predominantly agricultural, so the plant's nutrient removal helps reduce downstream impacts on the Gulf of Mexico hypoxic zone.
