Water Projects


In 2014 Park City was issued Utah Discharge Elimination Systems (UPDES) permits for the discharge of water draining from the Judge and Spiro mine tunnels into McLeod and Silver Creeks. Water from both tunnels exceeds stream water quality parameters identified in these permits.

Due to the cost and complexity of bringing this water into compliance with UPDES permits, a Stipulated Compliance Order (SCO) was entered into between the Utah Division of Water Quality and Park City. The SCO requires that Park City develop and implement a plan to bring discharge into compliance by the year 2024 for the Judge Tunnel and 2033 for the Spiro Tunnel.

In addition, the existing Spiro Water Treatment Plant is aging and will soon need significant investment to keep it operational. While the existing plant consistently produces high quality drinking water, it cannot treat to certain parameters in the UPDES permits, and it lacks capacity to maximize available water from the combined Judge and Spiro Tunnel water sources.

This project will demolish the  existing Spiro Water Treatment Plant and construct the new 3Kings Water Treatment Facility in order to:

  • Improve water quality and reliability
  • Increase water treatment capacity to maximize use of available water from Judge and Spiro Tunnels
  • Increase overall City water supply resiliency and peak day capacity
  • Meet UPDES permits and Stipulated Compliance Order (SCO) for Judge and Spiro Tunnel water discharges



The SR-248 transmission water line improvement project is an integral part of the overall master plan for the treatment of water draining from the Judge and Spiro Tunnels. This project includes installation of new water pipelines to transport water from the Spiro Tunnel to the new 3Kings Water Treatment Plant (3KWTP), 3KWTP to the Boothill Tank, and from the Boothill Tank to Wyatt Earp Way. The project also includes the extension of a raw water line from Wyatt Earp Way to 3KWTP, which will facilitate treatment of additional mine tunnel water by adding to McLeod Creek with water imported from Rockport Reservoir.


Stage One of project will be completed in the following three phases. Work began on March 31, 2020. Crews will be working along the south side of SR-248, 7:00 a.m.-6:00 p.m., Monday-Friday.

  • Phase I  COMPLETE (March 31-June 15, 2020) Wyatt Earp Way to Comstock Drive
  • Phase II COMPLETE (June 15-August 3, 2020) Comstock Drive to Bonanza Drive
  • Phase III UNDERWAY (August 3-October 31, 2020) Bonanza Drive to Snow Creek Drive

Stage Two of the project - Boothill Tank to the 3KWTP - will resume in Spring 2021 with expected completion by October 15, 2021.


Throughout the project, traffic control along the south side of SR-248 may involve shifting lanes and temporary closures around work sites. Minimal impacts are expected to sidewalks and bike lanes. Brief water outages may occur while existing lines are taken out of service and connected to the new transmission lines. Customers will be notified 48 hours in advance of any anticipated water outages.


The SR-248 Transmission Water Line Improvement Project is an Essential Infrastructure project, as such work crews will follow strict guidelines to remain in compliance with the Summit County Public Health Order (Section 2) issued on March 23, 2020.

Western Summit Interconnect Project


  • A 12-inch water line connection between Park City's water system and the WBWCD regional water system, generally located parallel to the south right-of-way line of SR-248
  • A trail connection over the water line extending from Richardson Flat Road to the Park City Movie Studio
  • Replacement of the existing Pace Homer ditch culvert across Richardson Flat Road to address constant maintenance issues due to collapsing and undersized pipe

The project bid amount is $551,000


The project is scheduled to being in September 2019 and conclude in April 2020.

Public Utilities is pursuing reductions to our water and energy footprint by actively monitoring Upper Deer Valley for non-surfacing underground leaks from our water pipe network.


Approximately 20 sensors will be installed on fire hydrants in Upper Deer Valley. These sensors will measure pressure and acoustic noise in the system hundreds of times per second. Leaking pipes make noise that can be detected by these sensors. The data will be transmitted wirelessly to a software system that will analyze the data to identify where pipes are leaking. No impact to water users or the community is expected from these sensors.

 The project is scheduled to being on April 16, 2018 and will last approximately 6 months. 


Public Utilities manages water system assets through a program that is intended to keep the water system operating at defined service levels while reducing risk and achieving the lowest life-cycle cost.


The 2018 Water System Improvements Project includes a number of identified water distribution system infrastructure deficiencies and is intended to address water service reliability (recurring freezing and failing water services), water service metering accuracy (meter replacements), and water system operation and maintenance issues (inoperable isolation valves), and water loss (identifying and repairing leaks). 

The Project bid amount is $817,000.


The Project has been publically bid and a contract awarded to Daley Excavators. Work began in April 2018 and will  continue through May 2019. Crews will work through the winter on interior projects. No excavations will occur during the winter shutdown (November - March). 


The project consists of numerous smaller work items located throughout the City. See the Project Map. Customers should expect disruption in isolated and confined areas:

  • Impacted customers will be notified a minimum of 48 hours in advance of any planned work in the adjacent street(s).
  • Impacted customers will be notified a minimum of 48 hours in advance of any planned water outage. Water service shutdowns associated with the work are anticipated to be of a short duration (less than 2 hours).
  • Any access to a property necessary to conduct the work will be coordinated well in advance of the start of any construction.





Park City Council has identified Energy as a Critical Priority for the City. Public Utilities has identified improvements to the Jordanelle Special Services District (JSSD) to PCMC water delivery method as an opportunity to significantly increase Park City's water system energy efficiency. The project consists of two primary components:

  • New Deer Crest Pump Station
  • New Deer Crest to Bald Eagle Transmission Pipeline


The new Deer Crest Pump Station will be a buried cast-in-place concrete structure that is equipped with pumps sized to deliver flowrates ranging from 500 gpm to 1,000 gpm.

A new 12-inch diameter water transmission pipeline will convey the imported drinking water from the new Deer Crest Pump Station to Park City's existing Bald Eagle Tank zone. The new transmission line will be approximately one-quarter mile in length and will be routed along Deer Valley Resort's "Kimberly" ski run. The project budget has been established at one million dollars ($1,000,000).


Planning for the project began in 2016. Construction is scheduled to begin in June 2019 and continue through October 2019.


This project affords the following benefits:

  • Reduces pumping demands between water tank zones by over 50%. This represents a total annual energy savings of approximately 1M kWh.
  • Better utilizes the available storage capacity in the Bald Eagle Tank
  • Affords JSSD an emergency connection from Park City's water to JSSD's water system.
