6. Discussion and Background
Constructed in 1968, Reservoir 4 is a five million gallon welded steel water storage tank located at 5300 Avenida Palmar in the southeastern portion of Orange. This partially buried tank requires complete internal and external Cathodic Protection (CP) systems to prevent corrosion to the metal shell and structural elements. Recent annual monitoring surveys completed by the City’s authorized contractor have identified that the reservoir’s existing external CP system has reached its service life and is not able to provide sufficient protection as originally designed.
In July 2019, the City retained Corrpro Companies, Inc. to prepare plans and specifications for a new external CP system to replace the existing system. The project scope of work includes installation of a new exterior CP system rectifier, drilling and installation of six new anode beds comprised of silicone cast iron anodes with accompanying anode junction boxes and three test stations around the reservoir perimeter. The project will also include the relocation of the existing internal CP system rectifier to the new pump building, pavement trenching and restoration for new electrical conduits, wires, and reconnection to the existing power panel and meter.
The project was advertised on both July 22, 2021 and August 5, 2021. Bids were received and opened on August 19, 2021, with 4 bidders responding as follows.
