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.

10. ACH (Aluminum Chlorohydrate Chemical Storage - used for pre-treatment coagulation.
11. Clean in Place Skid - Used to heat prepare membrane cleaning solutions with chemicals.
12. Membrane Backwash Tank showing new floating tube settlers for improved clarification.
13. Belt filter press - Used to remove the most of the water from the sludge in the backwash tank prior to disposing.
14. Pumps to deliver treated water to post-treatment system
15. Post-treatment Granular Activated Carbon (GAC) Adsorber Tanks - used for finished water polishing and to remove any bad taste and odor.
16. Chlorine Generator System - Generates chlorine safely from salt solution. Used for final disinfection of plant water before it moves into the finished water tank and distribution piping system.
