City of Brentwood Water Treatment Plan Actuator and Control System Upgrades

The City of Brentwood Water Treatment Plant (CBWTP) upgrade replaces aging valve actuators and modernizes the plant’s control system. Work includes mechanical removal and installation of five actuator models (with one spare each), demolition of existing cable and network infrastructure, installation of new conduit, power, control and fiber‑optic wiring, and upgrades to control panels, PLC/RTU hardware, and network switches. The contractor must test, commission, and train CCWD staff on the new equipment, and handle associated civil, electrical, instrumentation, and safety compliance tasks. The project is subject to strict California OSHA, SWRCB, and prevailing‑wage requirements, with a mandatory plant‑shutdown window (Dec 13 2027 – Mar 31 2028) and liquidated‑damage penalties for schedule overruns. • Replace five types of valve actuators (one spare each) and perform associated mechanical work. • Install new power, control, and fiber‑optic infrastructure; modify and replace control panels, network switches, and related instrumentation. • Demolish existing cabling, provide civil‑electrical support (conduit, raceways, grounding), and complete testing, commissioning, and staff training. • Comply with Cal/OSHA, SWRCB permits, prevailing‑wage rules, and CCWD Contractor Safe Practices Handbook. • Schedule: NTP Jan 14 2027, 445‑day substantial completion, final completion by early May 2028, with a mandatory shutdown window Dec 13 2027 – Mar 31 2028.
