A.T.C. -Electrical Division was the Electrical Contractor for the new Trinidad Rancheria Water Treatment Facility.

This was a large, drought resiliency project for the Trinidad Rancheria, involving the construction of a new treatment building, wells, tanks, and treatment equipment.

This was a complex project consisting of motors, pumps, underground utilities, new electrical service, and a great deal of control wiring, motor controllers, VFDs, starters, analog controls, and network cabling.

We had the opportunity to work with one of the largest and oldest construction companies in the area, Mercer-Fraser, on this project.
