Patent ID: 7574834

Claim:
An above ground water storage device, comprising: a) a plurality of modular walls, coupled together in series to form a substantially continuous perimeter, each of the plurality of modular walls further including: i) a wall panel, inclined with respect to a horizontal orientation at an inclined angle; and ii) a support base, coupled to an A-frame portion of the wall panel the A-frame support base, including two legs defining a horizontal A-frame shape with a proximal end of each leg adjacent each other and a distal end of each leg spaced apart from one another, a cross brace extending between the legs intermediate the proximal and distal ends, and a truss having an upper leg member and a lower leg member with the upper leg member extending upward along the inclined wall panel and the lower leg member coupled to one of the A-frame legs; b) a liner, covering an internal side of the plurality of modular walls and an area encompassed by the continuous perimeter; and c) at least one modular corner wall, positioned with the plurality of modular wall panels to form a corner in the substantially continuous perimeter, the at least one modular corner wall having an angled side with an angle substantially the same as the angle of the inclined angle of an adjacent modular wall, and a non-angled side coupleable together in series with one of the plurality of modular walls.
