The District owns and operates an extensive wastewater collection, treatment and effluent disposal system. The District has approximately 300 miles of sewer lines. Portions of the system date back to the 1920’s.
As a result of the unique topography of the District, the collection system uses 21 lift stations to transport sewage through the system to the treatment facilities. If this District was located in a desert region, it may only need one or two lift stations. The largest of the District's stations may pump up to 4.0 million gallons per day while the smallest may only move 500 gallons per day.
The two wastewater facilities are the Willow Creek Wastewater Treatment Plant and the Grass Valley Wastewater Treatment Plant. Treated wastewater, which is called effluent, is conveyed from the Willow Creek Wastewater Treatment Plant to the Grass Valley Wastewater Treatment Plant for eventual disposal through a 10-mile outfall pipeline to a percolation site near Hesperia where the water percolates into the groundwater basin in that area.
Wastewater service charges reflect the costs of maintaining and operating the system around-the-clock.
