SUMMERFIELD WWTP - Secondary Treatment Plant in Marshall County, Kansas

SUMMERFIELD WWTP is a municipal wastewater treatment facility located on Arrowhead Road in Marshall County, Kansas. It serves a small population of 211 residents, reflecting the rural character of the area. The plant is situated in the northeastern part of the state, within the Big Blue River watershed. The plant provides secondary treatment, which is the standard biological treatment process required by the US Clean Water Act for municipal facilities. With a designed capacity of 83.28 and a discharge volume of 79.49, the plant operates near its capacity. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits to protect water quality. The treated effluent is discharged into local streams that flow into the Big Blue River, a tributary of the Kansas River. The Kansas River ultimately drains into the Missouri River and then the Mississippi River, making this plant part of a vast inland drainage network. The surrounding area is primarily agricultural, and the plant plays a key role in preventing nutrient pollution in downstream waters.

The plant discharges into the Big Blue River basin, which flows into the Kansas River and eventually the Mississippi River. This watershed supports diverse aquatic life and is important for regional water quality. The plant's secondary treatment helps reduce organic pollutants and nutrients, protecting downstream ecosystems from eutrophication.
