Underground water reservoir
First Claim
Patent Images
1. An reservoir for underground water storage associated with a building having a roof receiving precipitation comprising:
- a structurally reinforced tank being elongate and shallow, and being constructed of two attachable upper and lower bodies;
a water inlet feeding water into the tank;
a conduit transmitting water from the roof to the inlet;
valve selectively controlling water entry into the tank;
an automatically actuated overflow associated with the valve for directing water away from the reservoir when the valve is to so control the water;
a pump integrally housed on the reservoir in a compartment, said compartment being accessible to the surface;
an outlet conduit associated with the pump for directing retained water to a selected location;
a first control for selectively operating the pump, being located remote from the reservoir in the building;
a second control associated with the first control to deselect said first control when inadequate water for pumping is in the reservoir;
a sump integrally formed in the lower body for trapping sediment;
said upper and lower bodies being of a common geometry so as to be formed from the same molds and adapted for nesting in one another prior to assembly for use.

Abstract
An underground water storage reservoir has a molded tank of attachable upper and lower bodies, the bodies being of common geometry nestable for storage and transportation prior to installation, the installed reservoir co-acting with a precipitation receiving roof of a building, water inlet, conduits, valve and overflow, controllable pump and a sump to utilize water from the reservoir.

8. A liquid storage reservoir for a building comprising:
-
means for holding said liquid until needed having walls, floor panel and top panel, and being reinforced for structural integrity when buried below grade level in proximity to said building; means for collecting meteorological precipitation on the building and directing the liquid from the building to the reservoir; means for controlling the inlet of liquid into the reservoir to automatically selectively flow the liquid into one of the reservoir or an overflow network; means for removing the liquid from the reservoir being a pump with an intake and an outlet, the outlet directing flow to a desired location, and having a low water sensor including a cut-off to stop the pump; means for distributing said liquid for use to one of either the interior or exterior of said building; and said means for holding further comprising an elongate and shallow envelope of substantially rigid sheet material formed with arcuate corner joining said walls and panels, and being reinforced by molding substantially "U" section ribs as portions of said sheet and having an integrally molded shape forming a platform and sump wherein said shape forms the platform when in said top panel and forms the sump when in the bottom panel. - View Dependent Claims (9, 10, 11, 12, 13)

14. A water storage reservoir in association with a building comprising:
-
a roof and gutter system on said building directing precipitation flow to a downspout; an underground storage tank molded from a pair of top and bottom shapes of substantially identical geometry, said tank having an inlet and an outlet;
said tank being a substantially shallow shape having arcuate ends and sides above a floor panel and below a top panel and further having a plurality of reinforcing ribs supporting said shape when buried below grade level;an intake conduit directing flow from said downspout to said inlet; a float valve associated with said inlet for opening said inlet when the water level is below a first level and closing said inlet when said water level is at a second level; an overflow network distributing flow from said inlet conduit away from said tank when said valve is closed; a pump associated with said outlet having a pump inlet pipe for raising water from said tank to said pump and having an outlet conduit directing said flow from said pump to a desired location in association with said building; said pump being mounted on a platform integrally formed in and raised above said top panel and said pump inlet pipe extending to and terminating in close association with an integrally formed sump formed in and extending below said bottom panel; said sump and said platform being molded in said bodies so that said bodies may be inverted when disassembled for transport and may be produced from the same molds. - View Dependent Claims (15, 16)
