Abstract
Abstract An above-ground secondary containment dispensing system for a primary tank holding liquids. The system includes a 10,000 gallon primary tank and a secondary containment unit which includes a dike surrounding the tank. In the preferred embodiment, the dike is a right parallepiped having an open top and a floor. Preferably, the dike is provided with internal support means to support the tank above the floor of the dike and an external support means to support the dike above the ground to enable the entire unit to be moved easily. A loading platform is mounted adjacent to the tank and includes both glycol and water loading arms. In the preferred embodiment, a single pump is used for both tank off-loading and to issue product to the de-icing units. Preferably, a level detector mounted in the tank is operatively associated with the pump to disable the pump when the tank is full and/or to provide an indication to a user when the tank is full. Preferably, the usable volume of the dike is at least 100 percent of the usable volume of the primary tank.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
368 words
An above-ground secondary containment and dispensing system for a primary tank holding a fluid comprising: a) a dike surrounding said primary tank; b) a loading platform adjacent to said dike adapted for permitting an operator to dispense said fluid from said primary tank to a fluid receiving vehicle; and c) a fluid handling system located in a portion of said dike adjacent to said primary tank and having pump means for off-loading said fluid into said primary tank and dispensing said fluid stored in said primary tank, wherein spills from either said primary tank or said fluid handling system are contained with said dike, wherein said fluid handling system located in a portion of said dike adjacent to said primary tank and having pump means for off-loading said fluid into said primary tank and dispensing said fluid stored in said primary tank includes: i) a fluid inlet located in one wall of said secondary containment dike and connected to said pump means; ii) a first fluid outlet connected to said primary tank for permitting said primary tank to be filled; iii) a second fluid outlet connected to said dispensing system for permitting fluid to be dispensed; and iv) means operable to selected between said first and second fluid outlets, whereby said pump means is operable to selectively fill said primary tank and dispense said fluid, wherein said means operable to select between said first and second fluid outlet includes a first tee between said fluid inlet and the inlet of said pump means, a second tee between the outlet of said pump means and said fluid outlet, and a third tee between said first tee and said second tee and wherein said means operable to selected between said first and second fluid outlet further includes a first valve between said first tee and said third tee and a second valve between said second tee and said fluid output, each of said first and second valves being movable between a first open position and a second closed position, wherein when said first and second valves are closed said pump means fills said primary tank and when said first and second valves are open said pump means dispenses said fluid.
