Definitions

  • Infiltration systems are used to prevent flooding during heavy rainfall and otherwise deal with excess water in situations where the volume or flow rate of water is too high for surface water drainage systems to cope with (or where there is no surface water drainage system).
  • a soakaway is constructed by digging a hole in the ground and filling the hole with stone, rubble, plastic (e.g. plastic crates) and/or other elements. It is designed to allow water to filter through it and soak into the ground.
  • underground tank system should be interpreted broadly in the context of this specification. Embodiments of the invention may be applied not only to infiltration systems, but also to other underground tank systems like septic tanks, grease and fat tanks, attenuation tanks, sand, oil and grease traps, agricultural tanks, and the like.
  • an underground tank system which comprises a plurality of panels including at least a pair of side panels, an end panel and a top panel, wherein the panels are configured to be assembled substantially underground so as to define an internal water receiving zone between the panels, and wherein the side panels and the end panels are provided with angled slots permitting water to travel into or out of the water receiving zone, the slots in each of the side and end panels being angled between about 40° and about 80° relative to an axis which extends along a height of the panel.
  • the underground tank system may be a so-called “panelled tank”.
  • the slots may be substantially cylindrical slots.
  • the water receiving zone preferably has a substantially rectangular cuboidal shape when the panels are assembled underground.
  • the tank system may be an agricultural tank system.
  • the slots are angled so as to allow water to ingress the water receiving zone via the slots and the system further comprises a barrier component substantially preventing particles such as sand and/or rock from entering the water receiving zone.
  • the slots may preferably be angled between about 45° and about 75°, more preferably between about 50° and about 70°, around more preferably approximately 60°, relative to the axis (Z-axis) which extends along the height of the relevant panel.
  • the panels may be manufactured/constructed primarily from cementitious material, e.g. by means of casting in suitable moulds.
  • the top panel may include a removable lid. Lifting of the lid may facilitated by a handle element and/or lifting arrangement incorporated into the lid during the casting process. At least one of the panels, e.g. one of the end panels, may be provided with an inlet/outlet hole which operatively exposes or provides fluid communication to the water receiving zone.
  • the slots may be provided substantially across an entire area defined by each side panel and/or substantially across an entire area defined by each end panel.
  • the kit may include inserts configured for defining the angled slots in the side and/or end panels during the casting process.
  • Each insert may include a plurality of tubes and optionally caps for sealing off ends of the tubes.
  • the kit may further include at least one wire holder, or wire spacer.
  • the wire holder may be configured to receive a wire mesh junction of the wire mesh.
  • the wire holder may be designed to retain the wire mesh junction substantially centrally in the mould, when taken along a vertical axis or direction of the mould, and/or to support the wire mesh junction at a desired height above a bottom surface of the mould.
  • the wire holder may include a set of receiving formations at opposite ends thereof, wherein each set of receiving formations is configured to accommodate a different thickness/diameter of wire.
  • the receiving formations may be defined by legs of the wire holder which are also used to support the wire holder in an upright condition.
  • the legs not being used to receive the wire mesh junction may be located at a bottom of the wire holder to support it in the upright condition, while the other set of legs may be located at the top of the wire holder.
  • the method may include, prior to the casting step, inserting one or more of the inserts, the reinforcing material, the wire holder and the lifting arrangement into one or more of the moulds.
  • Assembling the panels may include securing edges of the panels to each other, e.g. using cementitious material.
  • Figure 1 is a perspective view of an exemplary embodiment of an underground tank system according to the invention, wherein the exemplary embodiment is employed as an infiltration system;
  • Figure 3 is a top view of the tank system of Figure 1 ;
  • Figure 4 is a side view of the tank system of Figure 1 ;
  • Figure 5 is a top view of one of the side panels of the tank system of Figure 1 ;
  • Figure 6 is a front view of the side panel of Figure 1 ;
  • Figure 13 is a front view of the cap of Figure 12;
  • Figure 16 is a first end view of the wire holder of Figure 15;
  • Figure 27 is a photograph illustrating an example of the manner in which an underground tank system according to the invention may be lengthened by adding addition panels thereto;
  • the side panels 12 and end panels 14 are each provided with a plurality of slots 26.
  • the slots 26 are angled and substantially cylindrical in shape.
  • the slots 26 are arranged in sets of three (see the circled portion 28 in Figure 2).
  • Each set 28 has two slots that are aligned vertically and a third slot, located between the first two slots and positioned slightly higher than the first two slots.
  • the sets 28 of slots 26 are in turn arranged in rows and columns across the panels 12, 14 as shown in Figures 1 , 2, 4 and 6.
  • the slots 26 are angled so as to extend downwardly from an inner face (see face “B” in Figure 7) to an outer face of the panels (see face “A” in Figure 7).
  • the inner face is the face adjacent to the internal water receiving zone. Accordingly, when used as an infiltration system, the angle of 60° referred to above is the angle between the inner face “B” and the axis Z / height of the panel 12.
  • the system 10 may be used as an agricultural tank.
  • the panels 12, 14 are essentially installed “upside-down” so that the slots 26 are angled so as to extend upwardly from the inner face to the outer face.
  • the acute angle referred to above would be the angle between the outer face “A” and the axis Z / height of the relevant panel.
  • the system 10 may have a barrier component, e.g. it may be wrapped or in shade cloth or other suitable material to prevent sand (and other particles) from entering the water receiving zone.
  • water entering the system 10 can be piped or pumped, e.g. to an above-ground storage tank or irrigation system.
  • the slots 26 may be formed in the panels 12, 14 by using inserts such as the insert 34 shown in Figures 8 to 11 .
  • a wire holder 52 or wire spacer may be used during the casting process to keep the reinforced wire substantially centrally positioned in the mould, thus maintaining strength and durability of the tank system 10.
  • the wire holder 52 is employed to support the wire at a desired height above a bottom surface of the mould, i.e. to keep the wire at a desired height along a vertical axis/direction of the mould.
  • Embodiments of the present invention may provide numerous advantages.
  • the tank system described herein provides an empty/void internal chamber with more holding capacity than conventional systems. It may thus act as a storage tank during heavy rains or the like and can be drained if necessary.
  • the tank system is relatively easy to manufacture and install, and can also be accessed and cleaned after installation.
  • an easy, modular “add on” system is provided, as described with reference to Figure 27.
  • the side panels and end panels may be substantially solid, in which case the tank system may be used as a septic tank, grease and fat tank, attenuation tank, and/or a sand, oil and grease trap. Aspects of the invention such as the wire holder and the lifting arrangement may still be employed in these embodiments without employing the angled slots.
  • the tank may be provided with intermediate or central panels between the end panels. This may define a plurality of compartments within one tank. Openings may provide fluid communication between the compartments, e.g. a large, square opening may be employed.
