There is provided a plastic infiltration unit comprising: a top deck which extends in a plane, at least one pillar extending from the top deck for supporting the top deck, wherein the top deck is provided with at least one integrated connector arranged to connect the plastic infiltration unit with another at least one integrated connector, of another plastic infiltration unit in a side by side arrangement.

A stormwater planter system containing plant material being comprised of a container fabricated of concrete, metal, plastic, or the like, that captures surface rainwater runoff or roof rainwater runoff whereby debris, sands, sediment, pollutants within the water are separated, treated and/or attenuated via multiple processes within a predetermined organic and/or non-organic aggregate material layer. The water is then discharged from the container either through internal pipe, or by direct infiltration into the subsurface environment. More particularly, the system incorporates features and structures to enable ease of maintenance, and healthier plant growth without competition from weeds and other non-desirable plant material.

A stormwater management system adapted for retaining or detaining stormwater. The underground system comprises a plurality of cells arranged in a generally honeycomb configuration. Each of the plurality of cells is generally hexagonal in cross-section and has an internal region. The plurality of cells are in fluid communication with one another to allow stormwater to flow from the internal region of one of the plurality of cells to the internal region of another of the plurality of cells.

Individual hexagonal 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. Adjacent modules are in direct fluid communications with one another via openings or windows in module side walls. Assemblies include various top and side pieces along with access ports for entry into said assembly.

The invention provides a modular rain garden system comprising a plurality of preformed channel sections 310 and two end panels 320. The channel section 310 and end panels 320 are configured to form a trough 300 when assembled to receive rainwater runoff. At least one end of the channel section has an engaging profile configured to engage with another channel section or one of the end panels. Divider panels 330 are provided to separate the trough into compartments, to provide additional strength or rigidity to the trough or to control or limit the flow of water between compartments. The side walls 312 of the channel sections, the end panel 320 and the divider panels 330 are corrugated by means of projections or grooves 313, 321 and 331 respectively to increase the strength and load-bearing capability of the components.

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.

A permanent form (13) serving to form concrete structures and comprising sidewalls (11) comprises: an interior form (14) that forms the inner face of a side wall; an exterior form (16) that forms the outer face of the sidewall; and a plurality of vertical reinforcements (17) that are disposed between the interior form and the exterior form and that hold the exterior form alone or together with the interior form. The exterior form and the interior form have: a plurality of base plates (18) that are formed from plastic into square plates and that are aligned so as to be in firm contact with each other in the vertical and horizontal directions; a plurality of central reinforcement plates (19) that are formed from plastic into square plates substantially equal in size to the base plates, that join four adjacent base plates, and that are aligned so as to be in firm contact with each other in the vertical and horizontal directions; and a plurality of end reinforcement plates (21) that are formed from plastic into rectangular plates are arranged into a quadrangular frame so as to join adjacent base plates while being located on the outer edges of the plurality of central reinforcement plates aligned so as to be in firm contact with each other in the vertical and horizontal directions.

Drainage systems are limited in performance and difficult to maintain. A drainage system is therefore specified, comprising the following: at least one infiltration device (10, 40) adapted to receive fluid; a collecting device (30) which is in fluid communication with the at least one infiltration device (10, 40) and is adapted to receive fluid from the at least one infiltration device (10, 40) and to discharge it to a fluid system (4), wherein a gateway device (52) is provided, which is adapted to receive and transmit sensor data to a receiving unit (60); at least one sensor (6, 6′, 7, 11, 11′, 14, 31, 31′, 32, 33, 41, 44, 42, 45) is provided, which is communicatively connected to the gateway device (52) for providing sensor data.

A septic system is provided that includes a septic tank having a plurality of compartments with a tank inlet in a first compartment. First and second vaults are positioned in a second compartment. The first vault receives fluid from the first compartment at a level near a fluid surface in the tank. A first flow inducer receives fluid from the first vault at a level near a bottom of the first vault, and releases fluid into the second compartment at a level near the fluid surface. The second vault receives fluid from the second compartment at a level near a bottom of the second vault and discharge fluid at a level near the fluid surface. Third and fourth vaults and a second flow inducer are positioned in a third compartment, the third vault receiving fluid from the second vault, and the fourth vault discharging fluid to a tank outlet.

Systems and devices for treating water runoff. A water runoff treatment device includes a primary receptacle and a secondary receptacle separated by a barrier having at least one treatment port to permit water to pass from the primary receptacle to the secondary receptacle. A runoff water inlet on one side of the primary receptacle receives drain flow into the primary receptacle. At least one treatment tank having a treatment medium is mounted over a corresponding one of the treatment ports. The at least one treatment tank includes a treatment tank opening to receive water for treatment by the treatment medium. The treatment tank connects to the treatment port to pass treated water into the secondary receptacle. A drain port is formed in the secondary receptacle to pass treated water out and into a flow of treated water.
