The District’s two wastewater treatment facilities are the Willow Creek Wastewater Treatment Plant and the Grass Valley Wastewater Treatment Plant. The Willow Creek facility is a flow equalization satellite plant of the Grass Valley Wastewater Treatment Plant. Secondary Treated Effluent from the Grass Valley plant is pumped through a 10 mile outfall pipeline to the District’s percolation site in Hesperia. In summer, a portion of the Grass Valley Treatment Plant effluent receives Tertiary treatment to Title 22 Recycled Water standards and is pumped to the Lake Arrowhead County Club for golf course irrigation.

Phase 1 was completed in 2010. A portion of funding for the project was through an Environmental Protection Agency (EPA) grant.
