The range of applications for underground tank installation are as varied as the site conditions in which CommTank performs each installation.  USTs typically store fuel that powers critical equipment, from generators to entire heating systems. Each one of our customers requires a unique choice of tank products. Our equipment and technology can satisfy a range of storage challenges and goals. 

One key reason customers appreciate CommTank is our crew’s professional expertise and technical skill. Our technology and construction teams go above and beyond what is expected of most tank installation companies. Our level of service and installation quality meets or exceeds the manufacturer's requirements. The fuel system work area is always kept neat and orderly with minimal disruption to the facility and grounds. We strive to provide customers with a professional and streamlined process of exceptional communication, from scheduling to coordination to completion of your job.

CommTank is a certified installer of Xerxes, Containment Solutions, and Highland underground tanks. Benefits of these products are outlined below, as well as examples of CommTank installation projects.

Fiberglass fuel storage tanks by Xerxes are a rust-proof alternative to steel tanks. Sizes and types of well- priced Xerxes products we install range from double-wall fiberglass, to multi-compartment fiberglass, and triple-wall fiberglass storage tanks. The choice of single wall fiberglass tanks is not recommended for use in New England because of the stability of mixed soils. Use of a double-wall fiberglass tank is a better application, as it provides twice the rigidity and strength of a single wall. Water and air exposure does not break down a double-wall fiberglass tank because fiberglass is not susceptible to internal corrosion.

Project examples for customers who use Xerxes products:

Containment Solutions Inc. (CSI) is the largest American fiberglass tank, manufacturer. The UL 1316 specification which governs underground fiberglass tank manufacturing was the result of CSI’s design work. CSI instituted and perfected the use of specially treated silica in their laminate matrix. The CSI tank wall is composed of resin, glass and specially treated silica that together results in a composite matrix compatible with petroleum industry products including:

  • All Octanes of Gasoline 
  • Jet Fuel 
  • AV-Gas 
  • Motor Oil 
  • Ultra-Low Sulfur Diesel (ULSD) 
  • Renewable Diesel and Bio-Diesel 
  • Fuel oil 
  • Ethanol, all blends up to 100% 
  • Oxygenated Motor Fuels 
  • Kerosene

Recent examples of Containment Solutions projects: 

Highland Tanks combine the structural strength of steel with the lasting protection of polyurethane. One thing common to all underground tanks is that they are coated in polyurethane, which provides permanent and effective corrosion protection for the life of the tank. If corrosion is your biggest concern, then the P3 line of tanks offers protection in three ways: dielectric coating, electrical isolation, and sacrificial anodes. Home use and commercial use models of these tanks are available.  In addition to fuel and lube oil storage tanks, models are also available for potable water storage, fire suppression, and wastewater. Each level and size of tank comes with a 20 to 30-year guarantee, depending on the model, when installed to the manufacturer's specifications by a certified tank installer.

The Steps of an Underground Fuel Tank Installation

  • Obtain necessary permits from the fire department
  • Pre-inspect all equipment and materials (including a pre-installation pressure test)
  • Install total containment sump and double-wall steel/fiberglass underground storage tank
  • Install tank supports, anchoring device, and approved backfill material (pea gravel)
  • Install a Veeder-Root Tank Management System
  • Install spill and overfill prevention measures sufficient to fulfill the requirements of 527 CMR 9.00
  • Install aluminum drop tube equipped with a stage I vapor recovery system and a double-wall flexible fuel line
  • Install a 2”, single-wall, fiberglass reinforced plastic buried vent line which will transition to a 2” schedule 40 steel vent riser with an approved vent cap. The vent riser will be mounted on the existing building wall
  • Install the vault cap and backfill to grade

The installed tank will be tested and left ready for operation. Tank and piping tightness, as well as the satisfactory operation of monitoring systems, will be ensured prior to the system being placed into operation. Satisfactory operation of the secondary containment system and overfill prevention devices, impact valves and line leak detectors will also be tested.

In a typical fuel tank installation, we will install a tank inventory management system, which will measure liquid at the interstitial space (between the inner steel tank and the fiberglass outside containment). It will measure the amount of gas or water (if any) inside the tank. It will also trigger an alarm in case the tank exceeds its filling capacity. The system will be able to detect any leaks that may develop in the underground feed and return lines.

Whatever the size or storage requirements of your project, our goal is to provide you with a storage tank system that will provide you many years of reliable service. For examples of our work please see the underground tank installation projects section of our web site.
