Report
RECOMMENDATION:
It is recommended that the Monterey County Water Resources Agency Board of Directors:
Approve the purchase order for three intake valve actuators in the amount of $103,000, to be installed at Nacimiento Dam’s Low Level Intake Chamber; and authorize the General Manager to execute the Purchase Order.
SUMMARY/DISCUSSION:
On May 24, 2023, the Monterey County Board of Supervisors passed Resolution No. 23-187 authorizing the Monterey County Water Resources Agency (Agency) to enter into a funding agreement with the California Department of Water Resources (DWR) for specified maintenance projects at Nacimiento Dam. The $6.1 mil State Funding Agreement, Agreement No. 4600015276, between DWR and the Agency was executed on May 31, 2023. Amendment No. 1 to the agreement was executed October 9, 2024.
Replacement of the Low-Level Intake Valve Actuators is an authorized maintenance project under Agreement No. 4600015276. The valve actuators open and close three 42” diameter butterfly valves located at the intake chamber. The intake chamber feeds water to the penstock for release through six 24” valves at the Low-Level Outlet Works, or to supply flow to the hydro-electric plant for power generation. The intake valve actuators were last replaced in 2013. This is considered a maintenance project.
Installation of the new valve actuators is planned for May 2026 and will be performed by divers. At that time, all hydraulic hoses and fittings within the intake chamber will be replaced, and an inspection of the intake chamber will be performed.
