An underground storage system includes a primary containment unit and a secondary containment unit. The underground storage system further includes a leak detection system which is fluidly connected to the secondary containment system, and which is adapted to detect fluid leaks in the primary contai

대표청구항 ▼

1. An underground storage system comprising: a primary containment unit;a secondary containment unit arranged to provide a sealed interstitial space relative to the primary containment unit;a vacuum system for periodically applying a vacuum to the secondary containment unit; anda leak detection system which determines a rate of change of vacuum pressure in the secondary containment unit as the vacuum system applies the vacuum, wherein the leak detection system is fluidly connected to the secondary containment unit and adapted to learn a vacuum rate of change of the secondary containment unit when the secondary containment unit is void of liquid, as the vacuum system applies the vacuum; wherein the leak detection system is adapted to detect a presence of liquid in the secondary containment unit if the determined rate of change of vacuum pressure in the secondary containment unit departs from the learned vacuum rate of change of the secondary containment system by a threshold amount. 2. The underground storage system of claim 1, wherein the primary containment unit supports a liquid and at least a portion of the sealed interstitial space is provided below the liquid supported by the primary containment unit. 3. The underground storage system of claim 2, wherein the primary containment unit is a fuel storage tank. 4. The underground storage system of claim 2, wherein the sealed interstitial space extends above the liquid supported by the primary containment unit. 5. The underground storage system of claim 2, wherein the portion of the sealed interstitial space is underground. 6. The underground storage system of claim 1, wherein the secondary containment unit includes an outer fluid conduit of a double walled fluid conduit and the primary containment unit includes an inner fluid conduit of the double walled fluid conduit. 7. The underground storage system of claim 6, wherein an interior of the inner fluid conduit is in fluid communication with an interior of a fuel storage tank. 8. The underground storage system of claim 7, wherein the double walled fluid conduit is a double walled pipe. 9. The underground storage system of claim 6, wherein the double walled fluid conduit provides a fluid connection between a liquid stored in a fuel storage tank and a dispenser. 10. The underground storage system of claim 1, wherein the primary containment unit includes a fluid conduit and the sealed interstitial space is provided about the fluid conduit. 11. The underground storage system of claim 10, wherein the fluid conduit is in fluid communication with an interior of a fuel storage tank. 12. The underground storage system of claim 10, wherein the fluid conduit is in fluid communication with a dispenser.
