Leoville I D WWTP - Secondary Treatment Plant in Leoville, Kansas

Leoville I D WWTP is a municipal wastewater treatment facility located in Leoville, Decatur County, Kansas. The plant serves a small population of around 100 residents, reflecting its role in a rural community. It operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required for most municipal facilities in the US. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 53.00 cubic meters per day and currently discharges approximately 37.85 cubic meters per day, indicating it operates below its design capacity. The treated effluent is discharged into local surface waters, which ultimately drain into the Kansas River basin and then the Mississippi River system. This watershed supports diverse aquatic life and provides water for agricultural and recreational uses downstream. The plant's discharge contributes to the overall water quality management in the region, helping to protect downstream ecosystems.

The plant discharges into local streams that are part of the Kansas River watershed, which flows into the Missouri River and eventually the Mississippi River. This river system supports a variety of fish and wildlife species, including migratory birds and freshwater mussels. The region's semi-arid climate makes water quality management important for maintaining ecological balance and supporting local agriculture.
