ABSTRACT OF DISCLOSURE A secondary containment system which may be manufactured in a factory, shipped and installed in a reasonably low cost and fully usable manner. In one embodiment, a large membrane of material, completely lines a collection and containment pit along with radiating trenches which drain into the collection pit. There is a substantial amount of membrane bulk which enables it to bunch in the corners and to provide slack which conforms to irregularities on the earthen walls and floor of the pit. Thus, localized stresses do not occur at places where the membrane bridges protections formed on the walls, in the corners, or the like. In another embodiment, the membrane covers a tank in the pit and drapes down to form deep areas where liquids may collect. A perimeter steel cable surrounds the hole. The membrane is attached to this cable so that the membrane is mechanically strong enough to meet the shoring requirements of the various occupational safety laws. Plastic zippers are used to close and to join the various membrane sections. A cement or sealent may be placed in confronting surface areas of the zipper to preserve the integrity of its seal over the long years that an installation may be expected to remain in the ground.
