This is a rehabilitation and maintenance project necessary to prolong the useful life of an existing 500,000 gallon water storage tank. The tank is owned by the Mammoth Community Water District (District) and is used to store and distribute water to customers in its service area. The capacity of the water tank will not change because of the project. Rehabilitation will consist of recoating the tank’s interior and exterior surfaces, installation of a new interior ladder, an air gap installation on the overflow pipe and add a manway on the sidewall. There may be weld patches on the existing floor of the tank depending on its condition. All old coating material from the interior and exterior of the tank will be removed and disposed of at a licensed landfill.
An established dirt road will be used to access the tank for the project. All vehicles and equipment will utilize existing barren areas for parking and conducting work. No vegetation will be cleared for the project. No temporary tanks will be used for this project. Work at the site will commence in May 2022 and is expected to be completed by September 2022.
