North Bay Intake Pump Station Replacement Project
Lake Arrowhead Community Services District  |  2017

The North Bay Pump Station, which was built in the early 1970s, is the main water supply source taking water from Lake Arrowhead and serving the general community for the Service District. Due to its age, there have been multiple pump failures over the years. This project was for the replacement of the North Bay Intake Pump Station. JIG provided full-time construction inspection to observe construction progress, monitor conformance with the construction plans and specifications, provide assistance with design deviations, and act as the District representative on site. 

The project included the following items:

• Demolition of existing facilities including pump station, vaults, pump, valves, and electrical equipment.
• Construction of on-shore pump station structure with stone veneer, access hatch with vertical turbine pumps and motors, piping, valves, and surge tank.
• Construction of electrical building extension including conduits, wiring, manual transfer switch, switchgear, VFD's and instrumentation. 
• Construction of in-lake pump station including submersible pumps, check and isolation valves, and electrical conduits.

Construction inspector duties included attendance to progress status meetings, ensure conformance to contract documents, construction observation, adherence to OSHA regulations, assistance with public relations, concrete mix inspection and testing, preparation of daily inspection reports, documented through daily photographs.
