A drainage channel support assembly including a support member adapted to support drainage channel, a pair of pegs arranged to anchor the support member to the ground, and a pair of coupling elements mounted to respective of each of the pair of pegs. The coupling arrangements are configured where on anchoring of the support member to the ground via respective of the pair of pegs either: in a first install mode, the coupling arrangement contacts an upper surface of the support member with the associated peg penetrating the ground along substantially the full length of the peg; or, in a second install mode, the coupling arrangement couples to a fitting which contacts the upper surface of the support member, the coupling arrangement contacting a lower surface of the support member for suspension of the drainage channel above the ground.

A golf bunker cleaning device includes a base having an open top end and an open bottom end defining an interior open space therebetween and the base configured to be buried below a ground surface of a golf bunker without filling in the interior open space. An extension collar is configured to be removably secured over the open top end of the base to increase a height of the interior open space to above the ground surface of the golf bunker, and a lid is configured to be removably secured over either the top end of the base or over the extension collar to enclose the interior open space. The extension collar comprises a plurality of collar latches each extending to a respective free end, and the base comprises a plurality of base locking apertures configured to releasable engage the respective free end of the plurality of collar latches.

Provided are methods and systems for draining underground soil moisture and water at a site. The methods and systems utilize a secured pipe system having a leading edge to drill the system into the earth, and perforations along portions of the surface of the system to receive accumulated water from underground and deliver it to the surface. A pipe cradle guide as provided is useful in the installation of the system. To also inject soil stabilizing materials (a mixture of sand and gel) into the earth using the secured pipe system, a removable canister is coupled to the distal end of the pipe system, and using water pressure the soil stabilizing materials are delivered to the soil by means of the secured pipe system.

The present invention is a system for treating land, either to reclaim or optimize the land. Embedded subsurface pipes deliver water to the land. The water may be loaded with soil-treating additives. As water streams from the pipes, it treats the land before passing into a drainage ditch around the periphery of the land. The water is removed from the ditch and recycled, removing contaminants (in reclamation operations) or adding more additives (in optimization operations), before returning to the pipes for another round of treatment, if necessary.

Fluid flow enhancing devices disclosed herein are adapted to enhance flow of fluid through subsurface watershed conduits, for example, culverts, drainpipe and the like. Such fluid flow enhancing devices advantageously enhance watershed runoff functionality in subsurface watershed conduits by altering watershed flow from a parabolic flow pattern to a rotational flow pattern while still accommodating fish passage requirements. This change in flow pattern beneficially provides turbulence that disrupts and flushes debris out of the subsurface watershed conduits. This disruption and flushing establishes a passive cleaning functionality within the subsurface watershed conduits that serves to clean the subsurface watershed conduits after suitable upstream water delivery event (e.g., heavy rain, controlled water release, etc.). In doing so, these fluid flow enhancing devices overcome one or more shortcomings associated with subsurface watershed conduits in a manner that overcomes drawbacks associated with conventional design and in-use considerations for such subsurface watershed conduits.

A method for managing the flow of water beneath a ground surface uses modules. Assemblies of such modules are disclosed. The modules include supports and a deck portion, and the supports are spaced apart and form multiple channels with a main section of the deck portion. The deck portion also includes at least one section extending from a main section.

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.

The present invention is directed broadly to a drainage channel support assembly 10 comprising a support member 12 adapted to support drainage channel 14, a pair of pegs 16a and 16b arranged to anchor the support member 12 to the ground, and a pair of coupling elements 18a and 18b mounted to respective of each of the pair of pegs 16a and 16b. The coupling arrangements 18a and 18b are configured where on anchoring of the support member 12 to the ground via respective of the pair of pegs 16a/b either: 1. in a first install mode, the coupling arrangement 18a contacts an upper surface of the support member 12 with the associated peg 16a penetrating the ground along substantially the full length of the peg 16a; or 2. in a second install mode, the coupling arrangement 18a couples to a fitting 22a which contacts the upper surface of the support member 12, the coupling arrangement 18a contacting a lower surface of the support member 12 for suspension of the drainage channel 14 above the ground.

A method is disclosed for manufacturing connectable or non-connectable elongate porous plastic profiles 12 from substantially continuous randomised extruded plastic strands made of recycled thermoplastics. Current manufacturing processes can manufacture similar products, comprising short partially melted plastic particles melded together forming planks. These planks, however, are inherently friable, easily broken and not readily connectable. These shortcomings are caused by the manufacturing method used, being friction plate agglomeration. This invention utilises an extrusion process, which produces substantially endless random strands of thermoplastic 13 which drop and are welded together to form a porous mass, which is then compressed into boards or planks by pulling the mass through a forming tool 6 and 7. The profile can be adjusted to form edge recesses allowing the planks to be fitted together, for instance to form area coverings, or they can simply be laid end to end to form drainage channels.

A subterranean irrigation system (100) has a plurality of fluid conduit (130) for applying a liquid from a source to an area of ground, to which said liquid is to applied while avoiding interference with the above-ground use of such area, wherein the fluid conduits (130) are connected (140; 500) relative to one another and wherein the plurality of fluid conduits (130) comprise a plurality of outlets to effect the distribution of the liquid to the ground area, wherein the plurality of outlets (600;621, 622, 623; 800; 821, 822, 823) are provided at an underside (602, 802) of a nose-shaped spout attachment (600, 800), wherein the spout attachment (600; 800) is attached at the side in the upper half of the fluid conduit (130; 230; 720) and wherein the underside (602; 802) comprises a rounded surface starting tangentially from the outer diameter of the fluid conduit (130; 230; 720) and ends in the nose-shaped free end of the spout attachment (600; 800).
