Willowbrook WWTP - Secondary Treatment Plant in Willowbrook, Kansas

Willowbrook WWTP is a municipal wastewater treatment plant located in Willowbrook, Reno County, Kansas, United States. The facility serves a small population of 88 residents, reflecting its role as a local treatment system for this rural community. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater. The designed capacity of 60.57 million gallons per day and actual discharge volume of 34.07 million gallons per day indicate the plant operates well below its capacity, typical for small systems with low population density. The treated effluent is discharged into local waterways that ultimately drain into the Arkansas River basin, contributing to the overall water quality management in the region. The plant's operation supports the protection of downstream aquatic habitats and complies with state and federal regulations.

The plant discharges into local streams that are part of the Arkansas River watershed, which flows through Kansas and Oklahoma before joining the Mississippi River system. The surrounding area is primarily agricultural, and the plant's secondary treatment helps reduce nutrient and organic loads that could otherwise impact downstream water quality and aquatic life.
