Dion & Sons AST Removal & Replacement

Jauregui & Culver, Inc. removed the three existing diesel above ground storage tanks (ASTs) located at the existing Woodside facility and replaced them with two 12,000 gallon cylindrical ASTs.

Jauregui & Culver, Inc. provided necessary drawings and submittals to the City in order to procure permits. The removal of existing tanks included the removal of the sheet metal roof, sheet metal wall and support framework, and chain-link gates. The existing ASTs were washed and lawfully disposed of. The existing AST masonry support structures, tank slab, curbing, and concrete drive slab were removed so that the new ASTs could be placed side by side with adequate setback distances between the building and the ASTs. The existing diesel below ground piping extending from the pump to the AST enclosure was cut and temporarily capped while Jauregui & Culver, Inc. installed a new SWFG piping transition sump and extended the piping. Jauregui & Culver, Inc. poured a new slab. We furnished and installed 6″ diameter concrete filled steel bollards. The ASTs were assembled and installed.

Jauregui & Culver, Inc. will continue to do the testing and maintenance of this facility, ensuring that it is safe, up to code, and working properly for Dion & Sons.


Fuel Polishing


When the mass power outage spread through Southern California and parts of Arizona in 2013, those who had generators and other forms of emergency power were ahead of the curve. They were prepared, but was their fuel?  If your diesel fuel has been stored or unused for a long period of time, then it is of utmost importance to have it polished.

A clean fuel system is essential for preventative maintenance for your diesel engine.  One of the main problems with diesel fuel is contamination from algae, microorganisms, fungus, yeast, and bacteria.  Algae survive on the hydrocarbons in the fuel and the oxygen in the water in suspension and in the bottom water.  If left untreated, the contamination can cause plugged filters, motor operation problems, and expensive repairs.  These preventable symptoms of unclean fuel can and will lead to unnecessary failure of your emergency generator. 

Early signs of contamination include but are not limited to:

  • Dark, smoky exhaust that persists even after the engine of your generator has warmed up.
  • Any discovery of corrosion in the fuel tank, or other metal parts that contact the fuel
  • Hard deposits on engine injectors are an early and often subtle indicator.  (Normal deposits should wipe clean with a cloth.)

The process is relatively simple.  We circulate the fuel through a special filter system which removes particulates and purifies the fuel.  We then place an additive into the fuel which kills any remaining algae and aids in keeping the fuel clean. There is a clear distinction between samples taken before and after polishing.  Upon request, samples can be analyzed through a lab to provide further verification of these results.


At Jauregui & Culver, Inc., we want to serve you and help prevent the expense and inconvenience of generator failure as a consequence of contaminated fuel.  It is recommended that your fuel be polished at least once every two years, though most major oil companies, engine manufacturers, and regulatory bodies recommend polishing yearly for back up power sources. In critical facilities, such as hospitals, fuel should be polished at least twice annually to ensure that it is in pristine condition when it is needed for use.

We’ll clean up your fuel and keep you out of the dark!

Sam’s Club Bakersfield #4819

Sam’s Club #4819 Bakersfield was a ground up fuel station. Jauregui & Culver, inc. excavated and installed two 20,000 gallon 87 gasoline and one 20,000 gallon split 12,000/8,000 10′ diameter Xerxes Underground Storage Tanks (UST) and deadmen.

We installed Fiberglass, APT, and steel piping to compile the fueling system, including trenching and gravel backfill. Two 3+1 gas/diesel dispensers and four 3+0 gas dispensers were installed, including the Under Dispenser Containment (UDC) basins, dispenser hanging hardware, and dispenser valance. Brine and vacuum tubing for the Veeder Root continuous monitoring and Pressure and Flow sensors in dispenser for the In Station Diagnostics (ISD). The Healy Clean Air Separator (CAS) was installed as part of the EVR II system.

We provided required Enhanced Leak Detection (ELD) testing of the fuel system at the conclusion of the installation of the fueling system and prior to opening. All fuel lines were purged and the dispensers calibrated, completing this project.
