Donner Summit Public Utility District treats water and distributes it to domestic users throughout the DSPUD boundaries. The water source is Lake Angela, located near the eastern boundary of the District. The District serves about 243 water customers, including residential, commercial, lodging, and resort users.
Water from Lake Angela, a District-owned lake and dam, and is processed through the nearby state-of-the-art treatment plant. The plant was recently upgraded to meet state requirements with respect to filtration and disinfection. The plant's capacity is estimated at 0.50 millions of gallons per day (mgd). From the treatment plant, distribution lines run west along Donner Pass Road, and serve that corridor, as well as Soda Springs. A portion of the Sugar Bowl area is also connected to this system. Additionally, the District provides water distribution parallel to Interstate 80, between Soda Springs and the Donner Summit rest area. The system includes a number of storage tanks and pressure-regulating devices to serve the various pressure zones over the variable elevations of the district. There is enough capacity in the water treatment and distribution system to roughly double the existing number of services. All water service is metered.
