SN CO SD 2 WWTP - Topeka, Kansas Wastewater Treatment Plant

SN CO SD 2 WWTP is a municipal wastewater treatment facility located at 601 Northeast Edgewood Drive in Topeka, Kansas. The plant serves a small population of 254 residents and operates under secondary treatment standards, which is the minimum required by the US Clean Water Act for municipal wastewater. As a small-scale facility, it plays a vital role in managing local wastewater within the Shawnee County area. The plant has a designed capacity of 113.56 megaliters and treats an annual discharge volume of 94.64 megaliters, indicating it operates below its full capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting program, which sets effluent limits to protect water quality. The treated effluent from SN CO SD 2 WWTP is discharged into a local water body that ultimately drains into the Kansas River basin. The Kansas River flows eastward to join the Missouri River, which then empties into the Mississippi River. This downstream network supports diverse aquatic life and provides water for communities and agriculture. The plant's operations help maintain the ecological health of these waterways by reducing pollutant loads.

The plant's discharge enters a tributary of the Kansas River, which flows through northeastern Kansas before joining the Missouri River near Kansas City. The Kansas River basin supports a variety of fish species and provides habitat for migratory birds. Downstream, the Missouri and Mississippi Rivers form a major aquatic corridor that sustains diverse ecosystems, including wetlands and floodplain forests. The plant's secondary treatment helps protect these waters from excessive nutrient and organic pollution.
