Spill bucket, sump and overfill testing

Spill bucket integrity, containment sump testing and overfill equipment verification from USTEX. Scope confirmed for the equipment at your site.

Spill buckets and containment sumps

Spill buckets collect small spills at the fill connection. Tank and dispenser sumps contain different equipment and may be part of the release detection system. We identify the components to be tested before quoting, including the number of buckets and sumps and the type of monitoring installed.

Integrity testing

Hydrostatic testing checks whether the containment holds test liquid under the required procedure. Test setup, liquid level and observations are documented. Existing water, fuel, damaged lids or inaccessible components should be reported before the visit; handling test liquid and any existing contents is part of planning the work.

Overfill prevention

The overfill check depends on the device installed. A drop-tube shutoff device, an overfill alarm and other components need their own verification procedure. We check the equipment and its operation for the agreed scope, then document the findings.

Plan the work around deliveries

Send the delivery schedule and identify a site contact who can provide access. Equipment quantities and condition affect the time on site. For Wisconsin facilities, we review the requested work against the applicable state requirements and the previous testing records rather than assigning one interval to every component.

Before the visit

• List the spill buckets, tank sumps and dispenser sumps to be tested.
• Send previous containment and overfill reports.
• Tell us about standing liquid or known damage.
• Confirm delivery times, access and arrangements for test liquid.
