Fuel Tank Selection


Western Global’s cube-shaped TransCube tanks feature 110% fluid containment and meet global transportation standards to provide safe fuel transport anywhere it’s needed.

Some things change constantly. Take cars, for example: Each year brings significant changes and advancements and someday, fully autonomous cars will likely rule the road. Fuel storage tanks on the other hand aren’t traditionally thought of as a rapidly changing product. However, more manufacturers are realizing the necessity of designing fuel storage solutions for the modern business, with features such as cloud-based remote fuel monitoring and global transportation approvals.

Diesel—the source of roughly 98% of energy consumed at the average jobsite—is a universal expense for operators. And as the construction industry changes and companies become more competitive globally, profit margins will continue to shrink for businesses that don’t find new and efficient ways to manage assets, including fuel storage.

Today, on-site tanks can simplify fuel management like never before and serve as more of an asset than the large steel cylinders they once were. To make the most of a fuel tank purchase, there are a number of factors to consider, such as the benefits of fuel monitoring, cleaning and maintenance costs, tank transportation, theft prevention, and more.


The larger the tank, the more stationary it tends to be. With options ranging from tanks that hold less than 150 gallons to ISO containers that hold upward of 25,000 gallons, determining the ideal solution starts with knowing how much fuel is used and how mobile the fuel supply must be. 

Transportation options can range from certified lifting lugs for handling with a crane to DOT-approved trailers. The most easily transported options are smaller trailer-mounted tanks typically holding between 200 and 1,000 gallons that are ideal for delivering fuel to remote sites. Some of the more important items to look for when buying a trailer-mounted tank include a sturdy trailer engineered to withstand the dynamic forces of the moving liquid while navigating rough, unpaved roads at jobsites. Tanks designed to comply with worldwide approvals, including UL, ULC, UN DOT, and Transport Canada, are usually the most rugged and well-designed. 

However, just because a tank is approved does not necessarily mean it’s the safest option. A lower center of gravity, for example, will make the tank less susceptible to tipping during transport. And for full-fuel transport, internal baffle plates prevent fuel surging to keep the vehicle stable. In most locations, tanks without baffles must be emptied, and often cleaned, prior to transport, which can require a third-party environmental company. If the tank is moved frequently, downtime and expenses add up quickly. 

If the job requires a larger tank of 1,000 gallons or more, consider how it will be moved around a jobsite. Round tanks often require a crane or loader to move. Most cube tanks can also be moved this way, but for added versatility, many also incorporate forklift pockets. Having more options can come in handy when equipment operators are busy or if certain equipment isn’t on the jobsite.

Environmental regulations must also be considered, and ground contamination is a major concern for on-site fuel tanks. While all tanks should meet basic environmental standards, round tanks—the traditional go-to storage option—come with the added expense of owning and cleaning secondary containment pans. The average bill for cleaning a containment pan is about $150, which can add up quickly in areas that require pans be cleaned on a regular basis or after it rains. An increasingly common feature on new tanks, particularly cube tanks, is double-walled 110% weatherproof containment. This eliminates the need for a secondary basin and can result in significant savings over the life of a tank. 


To meet the specific needs of different construction sites, it’s important to evaluate which features have the potential to increase value for a given operation. Tanks with multiple in- and out-ports, for example, allow the tank to serve as an auxiliary fuel supply while still being able to fuel trucks and other equipment. This can drastically extend runtimes for generators and light towers, as well as reduce the risk of running them dry. 

For jobs at remote locations, the benefits of remote tracking technology can pay dividends. Remote fuel tracking helps operators monitor and manage supplies from anywhere via the cloud. For those with multiple projects at different sites, this can make it easy to stay on top of fuel supplies and know when a delivery is necessary. 

Another location-specific consideration is the tank’s power supply. For mobile tanks and tanks at remote sites, adding options such as battery power storage and solar panels can help ensure the tank will always have the necessary power to run the pumps. And for locations with space limitations, tanks that can be stacked help free up space. 


For improved tracking and added security, cardlock systems are an efficient way to monitor who is pumping fuel and how much is dispensed. Businesses without fuel security often expect 2 to 5% of their fuel supply will go unaccounted for each year. For example, an operation using 20,000 gallons of diesel per week may lose as much as 1,000 gallons per week if 5% is unaccounted for. At $3 per gallon, that’s a $3,000 loss each week, or $156,000 each year, as a result of not closely monitoring fuel use. By tracking with a cardlock system, employers can easily monitor dispensing and greatly reduce losses by preventing employees and others from filling personal vehicles. 

Having tanks with secure access to fittings and dispensing equipment can also prevent unauthorized access and deter fuel theft. While many rely on regular padlocks, these are easy to cut and do little to deter thieves. Investing in more secure cabinets that position locks to be inaccessible to bolt cutters will better keep thieves at bay. While these security features will likely bump up the initial tank price, preventing a single theft of 50 gallons—roughly the capacity of a diesel pickup—may be enough to offset the difference. 

The remote fuel management systems available on Western Global tanks help employers monitor dispensing and reduce fuel theft.


No matter the tank or application, it’s important to buy from a trusted manufacturer. Reputable companies are more likely to design user-friendly tanks that generate higher ROI. Built-in ladders, convenient manhole access doors, and a solid warranty are strong indicators that a manufacturer is not cutting corners. Additionally, double-walled units with removable primary tanks make cleaning easier. Over time, tanks that are easier to clean and maintain will likely last longer and yield a much higher return. 

To extend the life of pumps, meters, and other components, look for tanks with enclosed, weatherproof cabinets. This is a common feature on modern cube tanks and increases the longevity of components compared to tanks with top-mounted components, where they are exposed to the elements. It is also worth checking whether your tank partner can supply the tank fully fitted with all the ancillary parts including pumps, placards, and filters so that the tank is ready to use once it is unloaded at your site. 

Additionally, choose a manufacturer that works closely with its customers to help select the ideal tank for the size and scope of the operation. Some manufacturers will even partner with a customer to ensure all regulations, from local to state and from EPA to DOT, are met. By providing these services, manufacturers can save customers time and hassle. Similarly, consider the manufacturer’s lead-time. Some tanks can be on site within days, while others take weeks.

As operators scramble to find new ways to decrease their operating expenses, fuel storage tanks should not be overlooked. And as regulations continue to change and the marketplace becomes more competitive, businesses should never ignore an opportunity to trim expenses and work more efficiently than the competition.
