Abstract

A sump cover containment assembly is provided for use with containment sumps utilized with underground fluid holding tanks having a sump cover with an access hole therein, a frame which communicates with the containment sump to which the sump cover is attached and a sump shield positioned between the containment sump and the frame and having a hole which communicates with the interior of the containment sump as well as with the sump cover access hole.

Claims

1. A sump cover containment assembly for use with a containment sump which has a top end with a hole therein, comprising:

a substantially hollow frame having an open top end and an open bottom end sized, shaped and oriented so that said bottom end fits around said top end of said containment sump;

a sump cover positionable over said top end of said frame, having at least one downward extension and at least one access hole extending through said at least one downward extension, said at least one access hole being of proper size, shape and orientation to facilitate positioning of a spill collector therein;

a lid for covering each of said at least one access holes in said sump cover;

first sealing means for sealing said lid to said sump cover;

second sealing means for sealing said sump cover to said frame to minimize intrusion of surface water into said substantially hollow frame, and

a sump shield substantially covering said top end of said containment sump, having a downward lip which extends downward about said containment sump between said frame and said containment sump, and an upward extension having a hole therein sized, shaped and oriented to mate with said at least one downward extension of said sump cover and to facilitate positioning of said spill collector therein.

2. The invention of claim 1, including third sealing means for restraining liquid positioned in said at least one access hole of said sump cover from entering soil around said containment sump.

3. The invention of claim 2, wherein said third sealing means includes an o-ring.

4. The invention of claim 1, including locking means for locking said sump cover to said frame.

5. The invention of claim 4, including fourth sealing means for sealing said locking means to said sump cover.

6. The invention of claim 1, wherein said sump cover includes a recess extending about said at least one access hole and wherein said first sealing means consists substantially of an o-ring.

7. The invention of claim 1, wherein said second sealing means includes an o-ring positioned between said sump cover and said frame.
