The Cowskin Creek Water Quality Reclamation Facility, also known as Plant 3, plays a dual role in the northwest portion of Wichita, Kansas, providing wastewater treatment while serving as a recreational space for the community. However, in 2015, the Kansas Department of Health and Environment (KDHE) issued a Consent Order mandating significant upgrades to the facility’s headworks and solids treatment systems to meet compliance requirements. The City of Wichita needed a solution that would address these demands while maintaining uninterrupted operations.
