Garden City WWTP - Secondary Treatment Plant in Garden City, Missouri

Garden City WWTP is a municipal wastewater treatment plant located on Lake Road in Garden City, Cass County, Missouri. It serves a population of roughly 1,949 residents, placing it in the small community category under U.S. Environmental Protection Agency (EPA) guidelines. The plant provides secondary treatment, which is the minimum standard required by the EPA's National Pollutant Discharge Elimination System (NPDES) for municipal facilities. With a designed capacity of 545.10 million gallons per year and an actual discharge volume of 511.03 million gallons per year, the plant operates below its capacity, indicating room for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed, contributing to the Mississippi River basin. The plant's operations help protect downstream aquatic habitats and maintain water quality in the region's streams and rivers.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic life, including fish and macroinvertebrates, and provides habitat for migratory birds. Proper treatment is essential to prevent nutrient pollution and maintain the ecological health of these downstream water bodies.
