The Wastewater Collection Department collects wastewater from approximately 10,000 homes and businesses in the city and urban growth boundary via 164 miles of piping, 2 lift stations and 3 force main pump stations.
The Wastewater Treatment Plant is an activated sludge secondary treatment plant, with ultra violet disinfection. Average dry weather flows are 5.5 million gallons per day (MGD), and peak wet weather flows are 30.0 MGD.
Biosolids from the Wastewater Treatment Plant are transported by Republic Services to the Dry Creek Landfill in White City.
The mission of the Wastewater Program is to meet the area's current and future wastewater collection and treatment needs, protecting human health, welfare and the environment.
