Butier is providing professional construction management support and special inspection services for the 1,2,3-Trichloropropane (1,2,3-TCP) Removal Treatment Plant Project. This critical project is required for the City of Chino Hills to comply with the State Water Resources Control Board mandate of an MCL of 0.005 micrograms per liter of 1,2,3-TCP, which was identified in the City’s groundwater wells supply. The water treatment facility will consist of two types of processes, granular activated carbon (GAC) to remove 1,2,3-TCP, and ion exchange to remove nitrates and perchlorate. Once completed, the project will produce nearly 3 million gallons per day of high-quality drinking water for residents and reduce the City’s dependence on costly imported water by over 75 percent.

Scope of Work

  • Construction of centralized GAC treatment plant to remove contaminants from the water
  • Installation of eight (8) GAC treatment vessels and electrical and control systems
  • Booster 9 Station improvements, including replacing pumps and motors and upgrading electrical units and telemetry system
  • Installation of perimeter wall, gates, fencing, landscaping, irrigation, site grading, piping, paving, and foundations
