Abstract: A liner system and method for installing the liner. The liner is composed of a synthetic material (HDPE or LLDPE). The liner has a base and walls and an undersurface. The undersurface includes integral therewith a plurality of discrete and independent radially disposed in spaced relation stabilizing members. The stabilizing members are exposed when the walls of the liner are positioned in a substantially vertical orientation relative to the base. This exposes the stabilizing members. The container may then be positioned in segments on top of the stabilizing members with the walls of the liner adjacent a wall of the container. In this manner, the container structure is fabricated about the liner. The advantages in this system relate to the maintenance of tension of the liner and the avoidance of having to position a large disc like structure over the top and within a cylindrical receptacle or container.

Abstract: A cover suitable for use on a liquid containing reservoir. The cover is composed of an envelope of porous material. The envelope is subdivided into discrete independent compartments. The compartments each have access to the internal volume for purposes of receiving a charge of hollow spheres. A centrally disposed collection member is positioned at the intersection of the independent compartments. This position is effectively the centre of mass of the cover once charged with spheres and permits expedited positioning and adjustment of the cover on the surface of the liquid container. The independent compartments facilitate controlled consolidation of the spheres therein and allow for simple positioning and removal of the cover which was challenging with prior art arrangements. The latter typically had to be folded or rolled causing manipulation difficulties and causing potentially hazardous situations during manipulation.
