Abstract:
A storage tank according to the present invention has a concrete bottom plate laid on a bottom part of a hole dug in the ground, a storage assembly provided on the bottom plate and accommodated in the hole, a concrete quadrangular tubular side wall provided around the storage assembly on the bottom plate, and a side-wall formation member configured to form the side wall into a square frame shape. The storage assembly has a plurality of square tabular partition plates, tubular spacers connected to the partition plates, and an outermost layer part provided on the outermost side of the storage assembly. The side-wall formation member has quadrangular tubular multi-step inner molds formed of a plurality of first plate members, a plurality of vertical reinforcing bars inserted into the multi-step partition plates, and a quadrangular tubular single-step outer mold which holds a plurality of second plate members by a plurality of separators.
Abstract:
Individual honeycomb shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant honeycomb shape for maximized structural strength and material use efficiency. Internal hexagonal or square shaped modules are assembled and encased by external hexagonal or square shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal hexagonal or square shaped modules drain into external hexagonal or square shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.
Abstract:
An underground water-storage system that includes a sump having a base and sidewalls that cooperate to define an open-topped box that defines a reservoir, a plurality of plastic water matrices each defining a void space for receiving water, and a lid. The sump and lid are formed of a reinforced geomembrane material and include welds and are prefabricated in a location remote from an installation site of the underground water-storage vault more than two days prior to installation.

Abstract:
An underground reservoir for storing water in alluvial deposits utilizes slurry walls keyed to an aquiclude beneath the reservoir to form a substantially impermeable water seal. A variety of water extraction/recharge apparatus provides for rapid and complete filling and draining of the underground reservoir. Such apparatus includes a plurality of wells distributed about the underground reservoir and a series of perforated pipes buried at a predetermined depth within the underground reservoir. A method of mitigating water table fluctuations resulting from the construction of an underground utilizes perforated pipes buried outside of the reservoir to transfer excess water from an uphill land parcel to a downhill land parcel that would otherwise experience a water shortage after construction of the underground reservoir.
Abstract:
A system for filtering, storing, and distributing groundwater, which includes a gallery having an elongated main body portion with an arch-shaped configuration with an enlarged inner chamber, having end walls covering each end thereof with an inlet opening for receiving the liquid to the enlarged inner enclosure, having side walls with laterally extending outer ribs and inner corrugations within the elongated body portion. The system also includes a collapsible filter having a hinged frame with a filtering material and a side portion for sliding into the inner corrugations of the gallery.
Abstract:
A captive air system for a water well. A submersible type pump is located downhole in a wellbore for pumping water from an aquifer to the surface of the earth. A special storage tank is buried below the surface of the earth. The tank has a relatively short vertical leg connected to a relatively long lateral leg which slopes downwardly away from the vertical leg. A water supply conduit is located at the lower end of the lateral leg. The pump outlet is connected to the interior of the vertical leg. A blowdown pipe is connected to the bottom of the vertical leg. The edge portions of the tank which join together the vertical and lateral legs serve as a dam so that as the liquid level in the storage tank is lowered, debris always remain in the bottom of the vertical leg while clean fresh water is delivered by the lateral leg.
Abstract:
A large capacity tank for the seasonal storage of hot water from electrical power-generating thermal and nuclear plants to be used seasonally to heat buildings, consisting of a large basin which comprises partitions dividing the basin into several portions communicating with each other in parallel and/or series relationship, at least one hot water supply input from said plants, leading to the distribution systems which open into one portion of the basin and at least one cold make-up and/or return water supply input for the distribution systems opening into another portion of said basin.
Abstract:
An underground infiltration crate for collecting, detaining, infiltrating, and storing grey water, rainwater, and/or storm water, may include a plurality of large plates attached to a plurality of small plates engaged to form a crate with tubular members positioned therein, wherein each tubular member is secured between a pair of large plates. Each of the large plates may be a framed panel that includes a four-sided periphery formed of a top periphery wall, a bottom periphery wall, and two side periphery walls; alternating parallel channels extending between the top periphery wall and the bottom periphery wall; at least one aperture extending through each of the alternating parallel channels; and at least one built in fitting integrated into the framed panel, wherein the built in fitting may be a ring-shaped groove that is sized to friction fit a tubular member therein.
Abstract:
Individual square shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant square tilling shape for maximized structural strength and material use efficiency. Internal square shaped modules are assembled and encased by external square shaped modules. Internal adjacent modules are in direct fluid communications with one another through a channel-less chamber. Internal square shaped modules drain into square shaped modules chamber where fluid is either stored or drained. Assemblies include various top and side pieces along with access ports for entry into said assembly.
