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

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.

Replacement of Empire Tank - Original and Future Rendering (*pdf)

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.
