LINN WWTP - Secondary Wastewater Treatment in Washington County, Kansas

LINN WWTP is a municipal wastewater treatment facility located in Washington County, Kansas, United States. The plant serves a small population of 385 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US 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 that removes biodegradable organic matter and suspended solids. With a designed capacity of 518.60 volume units and an actual discharge volume of 155.20 volume units, the facility operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local water body, which ultimately drains into the Kansas River basin and then the Missouri River system, contributing to the Mississippi River watershed. This inland location supports regional water quality and downstream ecosystems.

The plant discharges into a local watercourse within the Kansas River basin, which flows into the Missouri River and eventually the Mississippi River. This watershed supports diverse aquatic life and is important for regional agriculture and drinking water supplies. The secondary treatment process helps protect downstream water quality by reducing organic pollutants and suspended solids.
