3KINGS WATER TREATMENT PLANT PROJECT 

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

SR-248 TRANSMISSION WATER LINE IMPROVEMENT PROJECT

PROJECT OVERVIEW

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.

SCHEDULE 

Stage Two of the SR-248 transmission water line improvement project began in April 2021. Work will focus on repairs and landscaping on the south side of SR-248.  Preparation for a new sewer line near Bonanza Drive is scheduled to begin on Monday, April 26, which will include lane restrictions along Kearns Blvd./SR-248 west of Bonanza Drive while work is underway. Crews will be working along the south side of SR-248, 7:00 a.m.-6:00 p.m., Monday-Friday.

In May, work to install the water transmission line from Snow Creek Drive to Hotel Park City will begin and is anticipated to be completed this summer. Traffic control will be present along SR-224 from Thaynes Canyon Drive to Kearns Boulevard during this stage.

Stage One, which was completed in the following three phases, began in March 2020 and finished in October 2020.

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

IMPACTS

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.

ACTIVE WATER LOSS MONITORING IN UPPER DEER VALLEY

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.

PROJECT

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.

SCHEDULE

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

REPLACE EMPIRE RAW WATER STORAGE TANK

The Empire Raw Water Storage Tank located in Empire Canyon is an integral part of the overall master plan for the treatment of water draining from the Judge and Spiro Tunnels. The tank provides operation control of the water leaving the mine tunnel and entering the Judge Pipeline that conveys water from the Judge Tunnel to the new 3Kings Water Treatment Plant (3KWTP). The existing 45 year old aboveground steel tank has reached its end of service life and requires replacement.

PROJECT

The new Empire Raw Water Storage Tank project consists of the demolition of the existing 1 million gallon steel tank and construction of a new 200,000 gallon buried reinforced concrete tank. The size reduction is based on an operational needs evaluation. Existing above grade screening facilities and metering is being replaced with a buried vault.

The Project budget for the improvements has been established at $1,500,000.

SCHEDULE

Planning and design was completed in 2020. Planning Commission approval has been received. Construction is scheduled to occur in 2021, with demolition beginning in April and new construction completed by November.

CONSTRUCTION MITIGATION 

  • The existing trail in Empire Canyon will remain open during construction.
  • Construction access from Daly Avenue is prohibited.

SPIRO MINE TUNNEL REHABILITATION

Park City Public Utilities maintains two mine tunnels that were originally constructed in the early 1900’s. These two tunnels were constructed as ground water drainage tunnels that redirected water out of other active mining tunnels. Now abandoned from mining activities, the Spiro Tunnel produces a constant flow of water from the tunnel and is a substantial water source for Park City and is the headwaters of McLeod Creek. Recent studies conducted by the City, have found several areas in need of reconstruction for safe passage, maintenance and water collection.  

PROJECT

Phase One of the Spiro Tunnel Mine Tunnel Rehabilitation included studies and surveys to development recommendations and designs for tunnel reconstruction, ventilation improvements, replacement of 60-year old water conveyance piping within the tunnel, and improvements to facilitate long-term maintenance.

Phase Two implements the recommendations through tunnel reconstruction of the first 400 feet of the tunnel.  Reconstruction of the tunnel portal (entrance) includes a new plaza at the portal that will share the history of the tunnel.

Phase Three will be the implementation of the reconstruction of prioritized areas of the tunnel.

SITE CONSTRUCTION STATUS

Planning and design for the project began in 2019 and is being provided by Lithos Engineering,

A mining specialist contractor, Harrison Western, was selected to perform the tunnel reconstruction.

Phase Two tunnel work has been substantially complete. Tunnel piping work is underway. The portal is being reconstructed and the plaza is currently scheduled to be complete by summer 2021.
