The invention process for installing an overliner membrane begins with preparing a site by digging a pit for the installation of fuel tanks, for example, which may be associated with leakage or spillage of fluids. Then, ballast is packed under and around the tanks to support and stabilize their position, the ballast rising to a level which is above the tanks but below points where the leakage or spillage may occur. Next, a frame is built over the ballast in the area where the leakage or spillage may occur. A membrane is spread across the surface of the ballast and attached to the frame in order to form a basin in which this leakage or spillage may collect. The frame and the membrane are completely covered with ballast in a manner which maintains the side walls of the membrane in a vertical position. A trench system for delivery pipes carrying fuel from the tank to outlying locations contains a trench liner membrane which surrounds the pipes and drains into the membrane basin.

A process for installing an overliner membrane within a drainage pit, the process comprising the steps of: (a) preparing a site by forming a pit for the installation of apparatus which may be associated with leakage or spills of fluids; (b) piling ballast under and around said apparatus to support and stabilize its position, said ballast rising to a level which is above said apparatus but is below points where said leakage or spillage may occur; (c) building a frame over and resting upon said ballast in said area where said leakage or spillage may occur; (d) covering the ballast inside said frame with an overliner membrane which spreads across the surface of said ballast and attaches to a level on said frame which is higher than said leakage or spillage may rise, said overliner membrane being held by said frame in a configuration which forms a collection basin to catch said leakage or spillage; and (e) covering said frame and membrane, both the outside and inside of said overliner membrane, with ballast and at a rate which maintains the side walls of said membrane in a vertical position.
