ABSTRACT:
The device for detecting leaks in an underground fluid tank includes a tank liner extending across the bottom of the tank and upwardly substantially surrounding the sides of the tank. The tank liner includes a stiff plastic core having a surface defining a plurality of fluid passageways which is oriented tangentially to a drain pipe arranged below the tank and along the length of the tank and which has slots to provide passageways for fluid entering into the pipe. A permeable plastic membrane is wrapped around the core and the pipe to prevent fill from filling the passageways so defined. A leak tank is connected to the drain pipe for receiving fluid therefrom, and a pump is mounted in the leak tank to pump the fluid to a surface tank for inspection.
