United States Patent Application20050205157 Kind Code A1 Hutchinson, Ray J. September 22, 2005
Service station leak detection and recovery system
Abstract
A fueling environment that distributes fuel from a fuel supply to fuel dispensers in a daisy chain arrangement with a double walled piping system. Fuel leaks that occur within the double walled piping system are returned to the underground storage tank by the outer wall of the double walled piping. This preserves the fuel for later use and helps reduce the risk of environmental contamination. Leak detectors may also be positioned in fuel dispensers detect leaks and provide alarms for the operator and help pinpoint leak detection that has occurred in the piping system proximate to a particular fuel dispenser or in between two consecutive fuel dispensers.

Claims
1-20. (canceled)
21. A method of detecting a leak in a fueling environment's fueling distribution system with a fuel dispenser, said method comprising: dispensing fuel throughout a fueling environment in an inner conduit of a double walled conduit; capturing a leak from the inner conduit with an outer conduit of the double walled conduit; returning fluid leaked into the outer conduit to an underground storage tank through a submersible turbine pump.
22. The method of claim 21, wherein returning fluid leaked into the outer conduit through the submersible turbine pump comprises allowing fluid to pass into a casing construction of the submersible turbine pump.
23. The method of claim 21, wherein returning fluid leaked into the outer conduit through the submersible turbine pump comprises opening a valve associated with the submersible turbine pump to allow fluid to pass into a casing construction of the submersible turbine pump.
24. The method of claim 21, wherein returning fluid leaked into the outer conduit to the underground storage tank through the submersible turbine pump comprises connecting the fluid to a double walled pipe connecting the submersible turbine pump to the underground storage tank.
25. The method of claim 21, wherein dispensing fuel throughout the fueling environment comprises dispensing fuel with a main and branch piping arrangement.
26. The method of claim 21, wherein dispensing fuel throughout the fueling environment comprises dispensing fuel with a daisy-chained piping arrangement.
27. The method of claim 21, further comprising detecting the leak.
28. The method of claim 27, further comprising reporting the leak.
