Effingham WWTP - Secondary Wastewater Treatment in Effingham, Kansas

Effingham WWTP is a municipal wastewater treatment plant located in Effingham, Kansas, United States. It serves a small population of 578 residents, reflecting the rural character of the area. The plant is situated in Atchison County, within the state's northeastern region. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 405.04 units and an average daily discharge of 219.55 units, the plant operates below its maximum capacity. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Kansas Department of Health and Environment. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed, contributing to the larger Mississippi River basin. This downstream connection underscores the plant's role in protecting regional water quality and aquatic ecosystems in the central United States.

Effingham WWTP discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic life and is part of a major migratory corridor for birds and fish. The plant's secondary treatment helps reduce nutrient and pollutant loads, safeguarding downstream water quality in this agriculturally intensive region.
