A leak detection method that works for your underground storage tank (UST) will depend on several factors. This includes installation, maintenance, operational costs, configuration of the facility, temperature adjustments, as well as the availability of experienced installers for the job.
Most people skip it, but having a list of professional installers ready can save valuable time and expenses. Delays can lead to extensive and costly damages you may not be able to control. To find reliable professionals, ask them whether they have experience working in facilities such as yours.
Some sources where you can get references include fellow UST owners, trade journals, trade and state associations, regulatory authorities, etc. Once you determine a leak detection method and installer, you must maintain O&M of your UST system. This will prevent future leaks and can help you avoid a catastrophe.
The best way to detect leaks before they have the chance to do some damage is to install a secondary containment unit around the UST. The space between the primary and secondary tanks can be inspected for leaks easily. However, the bottom line is that the type of UST system you have will determine which leak detection method you should go for.
