3Kings Water Treatment Plant Project

Project Overview

The 3Kings Water Treatment Plant replaces the aging Spiro facility and treats 3,000 gallons per minute (gpm) of mining-influenced water—with room for an additional 1,500 gpm from Thiriot Springs Housed in a 48,000-square-foot footprint, the plant raises Park City’s drinking-water capacity, reliability, and resilience.

Our Role at 3Kings Water Treatment Plant

CMT Technical Services supported the project from early site assessment through final commissioning, delivering:

• Geotechnical investigations for deep excavation and foundations
• Environmental review and permitting support
• Civil design and surveying for off-site utilities
• Pavements engineering and construction management
• Accredited laboratory testing and special inspections
• Field materials testing, inorganic chemistry, binder & emulsion analysis, and concrete petrography

Key Benefits of 3Kings Water Treatment Plant

• Higher capacity — boosts total treatment to 4.1 MGD, expanding Park City’s water supply on peak-demand days.
• Cleaner water — multi-barrier processes remove metals from historic mine tunnels, supporting regulatory compliance.
• Operational resilience — modern systems, seismic-ready foundations, and on-site micro-hydro generation improve reliability.

Sustainability Highlights

Energy-efficient equipment, reclaimed water for golf-course irrigation, and responsible construction practices contribute to Park City’s climate goals. Learn More
