Document Description
Replacement of the existing diesel fuel underground storage tank with the above ground storage tank and replace the day tank with a new tank at the Rio Vista Water Treatment Plant (RVWTP). The storage tank and day tank are part of the diesel fuel storage system for the standby generator at the RVWTP
The Project will consist of the removal of two existing diesel fuel storage tanks, one 8,000-gallon tank and the other a 100-gallon tank, their replacement with identically sized tanks, and replacement of the piping between the tanks and the generator. During the Project construction a temporary 8,000-gallon above ground storage fuel tank will be installed to provide uninterrupted fuel supply to the standby generator. The new ConVault 8000-gallon diesel storage tank manufactured by Oldcastle Precast is comprised of double wall construction for 110% containment and rust resistance. The tank also has an integrated secondary containment comprised of a high performance, 30 MIL high density polyethylene membrane around the primary tank with an engineered concrete outer vault encasing both primary and secondary containment in 6-inches of steel reinforced concrete with an epoxy coating for corrosion and vehicle impact protection. The storage fuel tank will have the liquid monitoring system and the leak detection system installed. The 8000-gallon tank will provide fuel storage for the RVWTP standby generator and will be installed on a 20-inch-thick concrete pad with 6-inch concrete berm. The tank will be seismically braced and anchored.
The new Simplex 100-gallon day tank will replace the existing 100-gallon Pryco Inc. day tank inside the engine generator room, in accordance with all applicable Fire Code and National Fire Protection Agency 30 requirements. No changes will be made to the existing emergency generator’s current operation procedures.
