Welcome to the Donner Summit Public Utility District

CSDA publishes Regulations, a River and Ratepayers, an article highlighting the accomplishment managed between the District and community for the Wastewater Treatment Plant Expansion Project.

In June of 2015, the Donner Summit Public Utility District (DSPUD) completed a $24 million project converting its treatment process from a chlorination/de-chlorination process to a UV disinfection process resulting in highly treated, pathogen-free, crystal clear recycled water. This tertiary treated water meets or exceeds Title 22 requirements as regulated by the Regional Water Quality Control Board and is effectively cleaner than surface water.

DSPUD obtained the updated National Pollutant Discharge Elimination System (NPDES) Permit from the California Regional Water Quality Control Board, Central Valley Region, in June of 2015. This permit allows for the use of recycled water for snowmaking at Soda Springs Ski Area.

Beginning in December 2015, DSPUD will begin supplying highly treated recycled water to Soda Springs for snowmaking purposes. This allows the District to achieve two beneficial community goals: conserve precious potable water supplies and provide an alternate water source that will contribute to a successful ski season.

For more information about the safety, regulations and common uses of recycled water, view our fact sheet.
