Proactive Tank Cleaning and Fuel Polishing for Fuel Retail, Commercial & Backup Systems

Fuel contamination is one of the most common and costly risks for any business that stores or sells fuel. Whether you’re running busy retail fuel sites, relying on a generator for emergency power or fueling your commercial fleet, Flowco’s tank cleaning and fuel polishing services resolve the full spectrum of fuel quality issues.  

Research shows 36% of underground storage tanks contain some form of contamination, while 83% of ultra-low sulphur diesel tanks have moderate to severe corrosion – issues many operators are unaware of.  

Flowco’s fuel cleaning technicians bring decades of experience to proactively identify problems early and clean tanks comprehensively – usually within a day – with minimal disruption to operations and no manned entry required. 

Backed by Leighton O’Brien’s industry-leading technology, our process not only removes water, sludge, rust and microbial contamination, but also remediates phase separation and reconditions diesel. 

Global oil companies trust our services to manage fuel quality programs, restore fuel health and prevent damaged equipment. Don’t leave it to your customers to report slow pumps or engine issues – stay ahead of costly issues with proactive fuel quality management.

Resolving Fuel Quality Issues

Water Ingress icon

Water Ingress

Water is the primary cause of poor fuel quality and can enter tanks through multiple sources including contaminated deliveries, damaged seals, loose fittings, vapour vents and condensation. Flowco’s solution removes water by sweeping the entire tank floor from multiple access points and pumps it into a holding tank to settle. The treated, clean fuel is then returned to the tank, helping restore optimal performance.
Microbial Contamination icon

Microbial Contamination

Fuel microbes thrive in the water/fuel interface or sludge at the tank bottom. While biocides can kill existing growth, they often leave behind an environment that encourages recontamination. Flowco’s system eliminates 100% of microbial growth and the conditions that allow it to return, protecting fuel quality and preventing Microbial Influenced Corrosion (MIC).
Degraded Diesel icon

Degraded Diesel

Diesel fuel degrades over time, particularly in backup generators where turnover is low. Flowco restores aged diesel to specification, ensuring clean, reliable performance when it matters most. Annual reconditioning is recommended to keep your generator-ready fuel ready for any emergency.
Phase Separation icon

Phase Separation

Phase separation occurs when water in ethanol-blended fuel causes the ethanol and petrol to separate, rendering it unsellable. Flowco’s process removes free water and remediates the remaining fuel to refinery-grade quality - saving you thousands in not having to dump your fuel.
