Tank for service stations

Abstract

An improved storage reservoir assembly has increased resistance to leakage of fluid from the assembly into the ground. The assembly comprises a storage reservoir suitable for being buried beneath ground level and suitable for containing a fluid, at least one support unit attached to the reservoir and suitable for attachment to an above-ground canopy and an enclosure suitable for partially surrounding the reservoir. The enclosure is spaced from the reservoir so as to define a void therebetween, and the void is filled with a filling material suitable for decreasing leakage of fluid into the ground and/or assisting maintaining the buried condition of the reservoir within the ground. In an alternative embodiment, a reservoir includes at least one fluid-tight passageway therethrough for accommodating the insertion of at least one support unit suitable for attachment to an above-ground canopy and for supporting the above-ground canopy external to the reservoir.
