How does water get into your underground storage tank?
All storage tank systems, both underground and aboveground, constructed of any material, and storing nearly any product—gasoline, diesel, residential and commercial heating oils, aviation jet fuel, and others—are susceptible to damage if water is allowed to accumulate. The potential for damage applies not only to the tank, but also to the entire storage system.
Today’s fuels are more susceptible to moisture separation and accumulation. Also, removing lead from gasoline and sulfur from diesel has had the side effect of allowing microbial growth to occur more readily, since lead and sulfur inhibit microbial activity.
Ethanol and biodiesel are important in today’s fueling network. But allowing water to remain in these storage systems can cause fuel separation, fuel degradation, and non-metallic equipment compatibility concerns.
For all these reasons, it’s more important than ever to conduct regular inspection and maintenance of your entire UST or AST fuel storage system.

STI-SPFA's Total Cost of Ownership (TCO) web-based tool provides real-world data on fabrication, inspection, maintenance, touch-up, and repair costs for steel tanks versus other materials. Users can also input their own data, allowing "apples-to-apples" comparisons that reflect the real costs for differing materials over their entire life cycles.
The TCO cost analysis tool assists you in analyzing the total cost of ownership of three common types of flat-bottom, ground supported water storage tanks (with roofs) constructed in accordance with AWWA standards:
Access to the TCO tool is complimentary for all users, but you must register.
Then you can input and store data related to your tank or tank project, and/or study the default data presented in the program. There is no limit to the number of tank projects you can store here. Your data is retained for one year and is secure, only available to you.
