On-site diesel is great, but it doesn’t mean much if you can’t store it safely, access it easily, and monitor it effectively. Diesel fuel storage tanks offer the stability and control needed to keep equipment fueled without interruptions. But from construction sites to commercial fleets, the truth is…not every tank fits every job.
There’s a wide range of options for diesel tanks and fuel delivery services (permanent setups, portable diesel tanks, fuel monitoring devices, wet hosing, etc.). Whatley Oil has spent decades helping customers throughout Georgia and Alabama match their fuel needs to the right storage system. Here are a few tips we typically give to folks weighing their tank options.
Two Main Styles of Diesel Fuel Storage Tanks
Diesel fuel tanks come in a variety of sizes and formats. You’ll have to choose one that matches your fuel usage, space, mobility needs, and safety considerations. The two main styles are:
1. Portable Diesel Fuel Tanks
Portable diesel fuel tanks are built for mobility and convenience. Commonly used for short-term projects or remote job sites, these tanks make sense when you don’t need a large volume or when the work location is always changing. A portable diesel fuel tank often includes built-in pumps and fittings to streamline refueling.
These tanks are typically available in sizes ranging from 100 to 500 gallons. A 500-gallon diesel fuel tank strikes a balance between capacity and portability and is a common choice on mid-size construction sites.
2. Permanent or High-Capacity Diesel Storage Tanks
If your operation needs a stable, long-term supply, a fixed diesel fuel tank offers larger volume and more efficiency for recurring refueling needs. These tanks come in both horizontal and vertical configurations and can be customized for your space and usage.
If you run a fleet yard, warehouse site, or centralized equipment hub, a diesel storage tank can be a perfect way to make sure your vehicles and machines are never left waiting.
Four Features to Look For in Diesel Fuel Tanks
Not every tank is built the same. Here’s what to keep in mind when evaluating your diesel fuel storage options:
- Durable Material: Look for tanks made of corrosion-resistant steel or polyethylene. Outdoor tanks should be built to withstand environmental exposure.
- Double-Wall Protection Option: Many businesses opt for double-walled designs, which help prevent leaks and offer secondary containment. This can be an important factor for compliance and safety (and you should remember to ask your provider if a double-walled tank is required in your situation!).
- Pump Compatibility: Make sure your tank setup includes a fuel transfer pump suitable for your operation, whether manual or electric.
- Lockable Access: Security matters, especially in open construction zones. Tanks with lockable fill ports help prevent theft or tampering.
Don’t Forget Maintenance and Fuel Quality
Storage tanks don’t maintain themselves! Poorly tended tanks are a top cause of fuel contamination, leaks, and non-compliance issues. Water intrusion, microbial growth, and sediment buildup all reduce the quality of diesel and damage your equipment. In the long term, this is your fuel provider’s job — but it’s equally important to abide by maintenance best practices while the rental tank is located on-site with you.
Ask your provider how often they clean tanks, replace worn fittings, and use water detection tools to identify internal moisture. A few fuel storage safety best practices go a long way in extending the life of both your tank and your diesel.
Fuel Level Monitors Are Great For Avoiding Shortages
An empty diesel tank can derail your entire day. We highly encourage proactive monitoring sensors as a part of your tank setup. Remote tank monitoring systems allow you to:
- Track current fuel levels in real-time
- Receive alerts when it’s time to reorder
- Forecast fuel usage trends over time
It doesn’t really matter whether you're managing one diesel fuel tank or several across job sites — either way, modern monitoring tools simplify logistics and prevent supply gaps.
Compliance and Safety Are the Bottom Line
Improper diesel storage leads to (or at least risks) EPA violations, site shutdowns, or dangerous spills. State and federal rules mandate proper containment, labeling, and routine inspections for commercial diesel tanks. You can reduce your risk by choosing a compliant tank and working with a knowledgeable supplier.
