A cubic modular subsurface stormwater unit has equal top and bottom surfaces spaced apart by a set of four pillars, each of which runs from a corner of the top surface to a corresponding corner of the bottom surface. The pillars define a void having a generally cruciform cross section, the void opening onto each of the four side faces defined between the roof and the base. A line of units connected together in series side to side will have a long throughway formed by the respective voids in each unit, and a regular matrix of X- and Y-axis throughways will be formed as units are connected laterally on all sides. The unit is formed of identical halves which cam be connected together in any orientation due to the square configuration and to a mating connection which has mating parts symmetrically disposed about a diagonal corner-to-corner line.
A modular subsurface stormwater unit of generally cuboid external form having equal rectangular top and bottom surfaces spaced apart by a set of four pillars, each of which runs from a corner of the top surface to a corresponding corner of the bottom surface, said pillars defining therebetween a void having a generally cruciform cross section, said void opening onto each of the four side faces defined between the roof and the base.
A sub-unit of a modular subsurface stormwater unit, the sub-unit comprising a generally square face having a set of four half-pillars extending therefrom, one at each corner of the face, each half-pillar terminating at a mating connection which is adapted to mate with an identical mating connection of another identical sub-unit to provide a generally cuboid modular unit, the mating connections of the four half-pillars being disposed such that when two sub units are brought into engagement with their square faces aligned and the mating connections approaching one another, each of the mating connections on one sub-unit engages with a complementary mating connection on the other sub-unit, for each of the four aligned orientations of the two square faces.
A modular subsurface stormwater unit of generally cuboid external form having equal rectangular top and bottom surfaces spaced apart by a set of four pillars, each of which runs from a corner of the top surface to a corresponding corner of the bottom surface, said pillars defining therebetween a void having a generally cruciform cross section, wherein the top surface is provided with a central cut-out between the pillars to enable an inspection access point to be readily created in the top of any such unit in a system of laterally adjoined units by removing said cut-out.
