Title:
DOUBLE CONTAINMENT AND LEAK DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO1991002335
Kind Code:
A3
Abstract:
A double containment and leak detection apparatus including a tank, having a bottom and a surrounding shell, with a containment baffle means above the bottom and a leak detection means in a containment space between the containment baffle means and the tank bottom. The containment baffle means includes a baffle plate sealingly joined to the interior of the shell to form a sealed containment space between the containment baffle and the bottom. The leak detection means is installed in the containment space to detect the presence of stored material held in the tank in the event such material leaks into the containment space. The leak detection means is connected, through a leak-proof access, to means external to the tank for responding to such leaks of stored material so detected inside the containment space. The invention further includes a primary containment means, made of liner material, located inside the tank above the containment baffle means and within the shell, capable of containing such stored material. The invention further provides a method for converting existing tanks to incorporate the double containment and leak detection apparatus of the present invention into existing facilities.
