Hamilton WWTP SW - Secondary Wastewater Treatment in Hamilton, Missouri

Hamilton WWTP SW is a municipal wastewater treatment facility located in Hamilton, Caldwell County, Missouri, along the Chicago-Kansas City Expressway. The plant serves a small population of 215 residents, reflecting the rural character of the area. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants. With a designed capacity of 140.06 million gallons per year and an actual discharge volume of 79.49 million gallons, the plant operates below its capacity. The U.S. EPA's National Pollutant Discharge Elimination System (NPDES) permit program governs such facilities, ensuring compliance with water quality standards. The plant's treated effluent is discharged into local waterways that ultimately drain into the Missouri River watershed, a major tributary of the Mississippi River. This contributes to the overall water quality management in the region, supporting downstream aquatic ecosystems and recreational uses.

The plant discharges into the Missouri River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this agriculturally intensive region.
