A soil drainage device includes a host, at least one water collecting assembly and a piping unit. The host includes a host housing for receiving a control module and an air pump. The water collecting assembly includes an assembly housing defining a water collecting chamber and a water reservoir chamber, and having an upper penetrating bore and a plurality of openings for entering of water into the water collecting chamber through a filter unit. The water flows into and is stored in the water reservoir chamber. At least one air conducting pipe is disposed to introduce compressed air from the air pump into the water reservoir chamber to form a pressure so as to force water flow out of the water reservoir chamber through a water draining pipe.

Embodiments may be directed to processes, devices, systems, and manufactures involving water leaching systems. Embodiments may comprise one or more receiving chambers and a plurality of outriggers connected to one or more receiving chambers in such a way as to provide support against external loads acting on the one or more receiving chambers. The outriggers may be directly coupled with chambers and may be spaced apart from chambers as well. The outriggers may also be integrated with the chambers and may be added to or detachable from the chambers. The outriggers along with the chambers may each provide for leaching of wastewater or other water from them along one or more of their sides.

Systems and modular devices for roof or ground-level stormwater management are disclosed. A modular stormwater management device includes a water retention mat structured to absorb stormwater, a rigid frame structured to support the water retention mat, and a perforated surface structured to permit drainage of the stormwater from the water retention mat through the perforated surface. A modular stormwater management system includes a plurality of modular stormwater management devices, each of the modular stormwater management devices including a water retention mat structured to absorb stormwater, a rigid frame structured to support the water retention mat, and a perforated surface structured to permit drainage of the stormwater from the water retention mat through the perforated surface.

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.

A multi-axial geogrid possesses a series of interconnected strands or ribs that are arranged along at least two different axes within the plane of the structure. The strands or ribs have an aspect ratio, defined as the ratio of the thickness to width, of greater than 1.0, thickness being the direction normal to the plane of the structure. The geogrid can be manufactured by modifying the process parameters in order to create high aspect ratio ribs, using any of the various known methods for producing geogrids. A reinforced civil engineering structure, and method therefor, is formed by embedding in soil one or more horizontal layers of geogrid having high aspect ratio ribs. The reinforced structure shows improved rutting performance when subjected to vehicular traffic.

The installation of one or more prefabricated drains beneath the surface of sediment in a sediment pond utilizing suction or a vacuum to withdraw water from the sediment material to lower the water level down to the level of the prefabricated drains below the pond surface. Dewatering may be coupled with imparting vibrations to the material to further promote both additional dewatering and compaction of the sediment material in the pond. A suitably graded bottom ash, fly ash, sand or large-diameter-solid particle or sediment layer may be added on top of the horizontal drains to enhance dewatering of finer sediment material.
