Coffeyville WWTP - Municipal Wastewater Treatment in Coffeyville, Kansas

Coffeyville WWTP is a municipal wastewater treatment facility located in Coffeyville, Kansas, United States. It serves a population of about 9,628 people in the southeastern part of the state, near the Oklahoma border. The plant is situated in a rural to semi-urban setting, typical of many small to medium-sized communities in the Great Plains region. As a U.S. facility, Coffeyville WWTP operates under the Clean Water Act, administered by the Environmental Protection Agency (EPA) and likely permitted through the Kansas Department of Health and Environment. For a plant serving roughly 10,000 people, secondary treatment is the standard requirement, which typically involves biological processes to remove organic matter and suspended solids. Facilities of this scale commonly use activated sludge or lagoon systems. The treated effluent is discharged into a local waterway, likely the Verdigris River or one of its tributaries, which flows south into Oklahoma and eventually joins the Arkansas River. This river system drains into the Mississippi River and ultimately the Gulf of Mexico. The plant's discharge contributes to the overall water quality of the Verdigris River basin, which supports aquatic life and recreational uses downstream.

Coffeyville WWTP discharges into the Verdigris River basin, which flows through southeastern Kansas and northeastern Oklahoma before joining the Arkansas River. The Arkansas River then flows into the Mississippi River and reaches the Gulf of Mexico. The Verdigris River supports diverse aquatic habitats and is used for recreation and water supply. The plant's effluent must meet state and federal water quality standards to protect these downstream ecosystems, including fish populations and migratory birds that rely on the river corridor.
