KCK WWTP 20 Wastewater Treatment Plant, Kansas City, Kansas

KCK WWTP 20 WWTP is a municipal wastewater treatment facility located in Kansas City, Kansas, within Wyandotte County. The plant serves a population of around 26,550, placing it in the medium-agglomeration category for US facilities. Its location inland, far from coastal waters, shapes its discharge and environmental management approach. As a US-based plant, KCK WWTP 20 operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. For facilities serving populations of this scale, secondary treatment is the standard requirement, ensuring removal of organic matter and suspended solids. Regulatory compliance with federal and state standards is expected. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Missouri River via tributaries. The Missouri River is a major waterway that flows into the Mississippi River, supporting diverse aquatic life and providing water for downstream communities. The plant's operations contribute to protecting water quality in this important river system.

The plant's treated effluent enters the Kansas River basin, a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports a variety of fish species and provides habitat for migratory birds. The region's agricultural and urban runoff can impact water quality, making the plant's treatment role critical for maintaining ecological balance in downstream waters.
