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.

A water conserving, secure and environment protective device includes a stationary base, a reflux column connected with the stationary base and a floating mechanism assembly sleeved on the reflux column. The reflux column defining a plurality of reflux holes to reflux an external water source. A water absorption mechanism assembly includes a plurality of supporting frames, a water pump arranged on an upper portion of the supporting frames, and a plurality of water suction pipes communicated with the water pump to suck the external water source.

A drainage system for drying frac sand without heat comprises multiple layers through which liquid passes to dewater sand resting on the drainage system. At the bottom of the drainage system, perforated collection pipes, at least partially surrounded by rocks, collect the liquid and carry it to a collection pond for reuse. A cellular confinement layer comprises sections of panels which, upon expansion, have cells filled with rocks. A woven monofilament geotextile fabric layer comprising woven monofilament geotextile fabric sheets sewn together has sized openings which allow fluid, but prevent sand from passing through the openings. The top layer comprises perforated sheets of high density polyethylene welded together. A watertight liner sits below the perforated collection pipes and below the cellular confinement layer. Protective layers above and below the watertight liner prevent rocks from damaging the watertight liner.

A method of manufacturing a water detention chamber by providing a polymer melt, injecting a CO2 blowing agent into the polymer melt, and injecting the polymer melt and CO2 blowing agent blend into a mold cavity. The mold cavity defines an arch-shaped corrugated chamber having upstanding ribs and a flange having an upper surface and a lower surface. The flange has one or more protrusions, preferably elongated members, at the first end of the chamber. The flange also has one or more mating apertures or cavities at the opposite end from the protrusions.

A reservoir bag and method of use and implementation is disclosed herein. The reservoir bag may be configured for controlling surface water run-off and may include a plurality of cells with at least two adjacent cells in fluid communication with each other to allow water to communicate between the adjacent cells. To aid in the mobility of water, the bag may include one or more perforated pipes therein to direct flow of water through the cells and to an outlet.

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 storm water drain system and methods of assembling the same are provided. The system can be arranged to provide a water management function such as retention, detention, conveyance, or infiltration. The system can include a plurality of support modules positioned adjacent to one another to form a top deck, a bottom deck, and an interior space between the top deck and the bottom deck. The plurality of support modules can include a support module that has a bottom corbel extending from an outer surface of the support module. The bottom corbel can be located within the interior space and have a surface that contacts a portion of the bottom deck.

Provided is a mixed turf arranged on a soil and including: a synthetic turf, natural grass arranged in the synthetic turf, said synthetic turf including: synthetic filaments suitable to simulate grass blades and a backing consisting of a membrane suitable to support the synthetic filaments, the backing being further as a whole substantially draining, enabling transpiration and permitting the passage therethrough of the roots of said natural grass and which is non-biodegradable.
