MN CO SD 1 EASTSHORE WWTP - Eastshore, Kansas Wastewater Treatment Plant

MN CO SD 1 EASTSHORE WWTP is a municipal wastewater treatment facility located in Eastshore, Marion County, Kansas. The plant serves a small population of approximately 100 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 37.85 megaliters per year, with a similar annual discharge volume, indicating consistent operation. Under the US Clean Water Act, facilities of this scale are typically regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Kansas Department of Health and Environment. These permits set effluent limits to protect water quality in receiving streams. The treated effluent is discharged into local waterways that drain into the Cottonwood River, part of the Neosho River basin, which ultimately flows into the Arkansas River and the Mississippi River system. This watershed supports diverse aquatic life and provides water for agricultural and recreational uses downstream.

The plant's discharge enters local streams that feed into the Cottonwood River, a tributary of the Neosho River. The Neosho River flows through the Flint Hills region into the Arkansas River, which joins the Mississippi River. This watershed supports a variety of fish species and provides habitat for migratory birds. The area's agricultural land use means nutrient management is important to prevent downstream eutrophication.
