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. Excess District flows are stored in ponds at the Willow Creek plant for eventual treatment at the Grass Valley 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.

In April 2004, the District’s request for an amendment to the State Water Quality Control Board (SWQCB) Lahontan Region Basin Plan to allow the use of recycled water for outdoor irrigation at elevations above 3,200 feet was approved.
Phase 1 was completed in 2010. A portion of funding for the project is through an Environmental Protection Agency (EPA) grant.
The Lahontan Regional Water Quality Control Board adopted Order R6V-2007-0022 Master Water Recycling Requirements at its June 13-14, 2007 meeting. The following are links to the agenda and the adopted permit:
