Abstract

A surface containment system to contain liquid contaminates escaping from a vessel, the containment system having in one example: a water and oil impermeable barrier liner positioned below the vessel; a perimeter wall surrounding the vessel, the perimeter wall extending vertically from the ground surface and supporting a portion of the barrier liner so as to from a containment reservoir; at least one fluid conduit through the barrier liner, the fluid conduit having a filter configured to retain contaminates and configured to allow water to pass by way of gravity from the reservoir through the impermeable barrier; the perimeter wall formed of a plurality of wall panels connected by way of struts each having a vertical component, a base component anchored to ground.

Claims (47)

1. A surface containment wall support system configured to contain liquid contaminates escaping from a vessel, the containment system comprising:

a water and oil impermeable barrier liner resting on a ground surface;

the barrier liner formed of a thin film configured to conform to the ground surface;

a perimeter wall

horizontally surrounding the vessel;

the perimeter wall extending vertically above the ground surface;

the perimeter wall vertically supporting a portion of the barrier liner above the ground surface to form a containment reservoir configured to be positioned below the vessel and horizontally encircle the vessel such that any fluids leaking form the vessel will be contained in the barrier liner;

at least one fluid conduit through the barrier liner;

the fluid conduit comprising a hydrocarbon filter;

the fluid conduit configured to allow water to pass from the reservoir through the fluid conduit to the hydrocarbon filter;

the perimeter wall comprising a plurality of wall panels;

adjacent wall panels forming the reservoir connected by way of struts; and

the struts comprising a vertical component connected to the wall panels and a base component resting on the ground surface.

2. The surface containment wall support system as recited in claim 1 , wherein the fluid conduit comprises a valve configured to restrict flow through the fluid conduit between the barrier liner and the hydrocarbon filter.

3. The surface containment wall support system as recited in claim 1 wherein the hydrocarbon filter is a hydrocarbon solidifying filter.

4. The surface containment wall support system as recited in claim 1 wherein each base component of each strut comprises a ground engaging cleat configured to penetrate the ground and maintain position of the strut.

5. The surface containment wall support system as recited in claim 1 wherein:

each base component of each strut comprises at least one surface defining a void vertically therethrough;

the surface defining a void configured to allow passage of the shaft of a ground-engaging anchor and not allow passage of a head of the ground-engaging anchor.

6. The surface containment wall support system as recited in claim 1 further comprising a prefilter assembly positioned between the barrier liner and the hydrocarbon filter.

7. The surface containment wall support system as recited in claim 1 wherein the barrier liner consists essentially of polyvinyl.

8. The surface containment wall support system as recited in claim 1 wherein the barrier liner comprises polyvinyl and is between 6 mils (0.006″) to 250 mils (0.250″) thick.

9. The surface containment wall support system as recited in claim 1 wherein the barrier liner comprises polyvinyl and is between 20 and 50 mils thick.

10. A surface containment wall support system configured to contain liquid contaminates escaping from a vessel, the containment system comprising:

a water and oil impermeable barrier liner positioned on a ground surface;

a perimeter wall horizontally surrounding the vessel;

the perimeter wall extending vertically above the ground surface;

the perimeter wall supporting a portion of the barrier liner so as to form a containment reservoir configured to be positioned below the vessel and horizontally encircle the vessel such that any fluids leaking form the vessel will be contained in the barrier liner;

at least one fluid conduit through the barrier liner;

the fluid conduit comprising a hydrocarbon filter;

the fluid conduit configured to allow water to pass by way of gravity from the reservoir through the barrier liner to the hydrocarbon filter;

the perimeter wall comprising a plurality of wall panels;

adjacent wall panels forming the reservoir connected by way of struts;

the struts comprising a vertical component connected to the wall panels and a base component resting on the ground surface;

each wall panel comprises a first outer layer, second outer layer, a core between the first outer layer and second outer layer;

each wall panel comprises a top flashing attached to an upper edge of the wall panel, the top flashing overlaying a top edge of the first outer layer, the core, and the second outer layer, a portion of an outer surface of the first outer layer, and second outer layer.

11. The surface containment wall support system as recited in claim 10 wherein: each wall panel comprises a bottom flashing attached to a lower edge of the wall panel and overlaying a bottom edge of the first outer layer, core, and second outer layer, a portion of the outer surface of the first outer layer and a portion of the outer surface second outer layer.

12. A surface containment wall support system configured to contain liquid contaminates escaping from a vessel, the containment system comprising:

a water and oil impermeable barrier liner positioned on a ground surface, the barrier liner formed of a thin film configured to conform to the ground surface;

the barrier liner forming a perimeter wall horizontally surrounding the vessel;

the perimeter wall extending vertically above the ground surface;

the perimeter wall supporting a portion of the barrier liner forms a containment reservoir such that any fluids leaking form the vessel are contained in the barrier liner;

the perimeter wall comprising a plurality of wall panels;

adjacent wall panels forming the reservoir connected by way of struts;

the struts comprising a vertical component connected to the wall panels and a base component resting on the ground surface;

each wall panel comprises a first outer layer, second outer layer, a core between the first outer layer and second outer layer;

each wall panel comprises a top flashing attached to an upper edge of the wall panel, the top flashing overlaying a top edge of the first outer layer, the core, and the second outer layer, a portion of an outer surface of the first outer layer, and second outer layer.
