The Signal Hill Water Treatment Plant Project

4 Million Gallons per Day (MGD) Capacity - Completed Oct. 2004

The Signal Hill Treatment Plant represents the final stage of the Lost Canyon Importation Project completed in 2004. This plant treats water pumped up from 1,000 feet below in elevation near the inlet of Rockport Reservoir in Eastern Summit County. After the water flows through a 5 mile high pressure transmission pipeline, it is delivered at this plant. Here some raw water is split off for irrigation in Promontory and to feed the Quinns Junction Treatment Plant, owned and operated by Park City. The remaining water is treated to high quality drinking water standards and feeds into the Promontory Development and the rest of Snyderville Basin. The total capacity f the Lost Canyon Project is about 7,000 acre feet per year.

Pictures are all presented in order of the treatment process

Operations at Plant

One of the most amazing things about Mountain Regional Water District is that the highly trained, professional staff is able to do most of the heavy maintenance and construction of much of our new infrastructure themselves. This benefits all of us by empowering personnel which can respond to most any problem or emergency - quicklu and efficiently.
