Underground Tank Installation Service
The conditions for installing an underground tank are rarely the same from site to site and require a seasoned crew with professional expertise and technical skill. Our construction teams go above and beyond what is expected of most tank installation companies, and we meet or exceed 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 a professional and smooth process with exceptional communication throughout, from scheduling to coordinating to completing your job.
CommTank is a certified installer of Xerxes, Containment Solutions, and Highland underground tanks. The benefits of each product are listed below including examples of recent projects we completed:
Xerxes fiberglass fuel storage tanks are a rust-proof, cost-effective alternative to steel tanks. Xerxes products we install include double-wall fiberglass, multi-compartment fiberglass, and triple-wall fiberglass storage tanks. Single wall fiberglass tanks are not recommended for use in New England because of the stability of mixed soils. Double-wall fiberglass tanks address this issue by providing twice the rigidity and strength of the single wall. The double-wall fiberglass tank is not susceptible to internal corrosion because fiberglass does not breakdown when exposed to air and water.
Recent examples of Xerxes projects:
- Herb Chambers Lexus UST Installation
- Kelly Volkswagen Underground Gasoline Storage Tank Installation
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
- Motor Oil
- Ultra-Low Sulfur Diesel (ULSD)
- Renewable Diesel and Bio-Diesel
- Fuel oil
- Ethanol, all blends up to 100%
- Oxygenated Motor Fuels
Recent examples of Containment Solutions projects:
Highland Tanks combine the structural strength of steel with the lasting protection of polyurethane. All underground tanks 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. Theses tanks are offered in both commercial and residential models. In addition to fuel and lube oil storage tanks, models are also available for potable water storage, fire suppression, and wastewater. The tanks come with a 20 to 30-year guarantee, depending on the model, when installed to the manufacturer's specifications by a certified tank installer.
Recent examples of Highland Tank projects:
- Keene State College Underground Tank Replacement
- Herb Chambers BMW Gas Pump and Underground Storage Tank installation
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
Upon completion, 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 your project size or containment requirements, 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.
