| 20090279953 | MODULAR UNDERGROUND WATER MANAGEMENT SYSTEMS - The invention provides modular units, associated component parts, and assemblies of the modular units and component parts, including filtration systems, that are useful for making and using underground water management systems. | 11-12-2009 |
| 20090290936 | Regenerative stormwater conveyance system and method - A regenerative stormwater conveyance (RSC) system for treating and dispersing stormwater runoff is disclosed which includes an upstream entry point where water enters the system and an entry pool downstream from the entry point that collects water from the entry point. The RSC system includes one or more shallow aquatic beds that receive water from the entry pool in a serial manner and each of which includes a filtration structure for filtering water from the aquatic bed. Riffle weir grade control structures are positioned between the aquatic beds and transition water overflowing from each upstream aquatic bed to a downstream aquatic bed. Accordingly, collected stormwater runoff traverses the series of aquatic beds and riffle weir grading structures and is treated and safely detained, thus, conveying stormwater to groundwater through infiltration. | 11-26-2009 |
| 20100129154 | AUTOMATIC GATED PIPE ACTUATOR - An automatic gated-pipe actuator for controlling flow of an irrigation material to an agricultural region through an irrigation gate in a gated-irrigation pipe. The automatic gated-pipe actuator includes a gate valve for coupling to the gated-irrigation pipe, a gate actuator removably coupled to the gate valve and for actuating the gate valve and an automatic gated pipe gate control unit for controlling actuation of the gate valve. The control unit has a processor unit communicatively coupled to the gate actuator. Upon instruction from the gate control unit, the gate actuator will actuate and alter the disposition of the gate valve thereby altering the flow of irrigation material through the irrigation gate and to a portion of the agricultural region adjacent the irrigation gate. | 05-27-2010 |
| 20100254765 | Diverting storm surge-apparatus & method - An aqueduct assembly is provided as having a front gate assembly and a rear gate assembly. The front gate assembly has a front gate which will open to let water into the aqueduct assembly. When water begins to rise in the aqueduct assembly, a rear gate of the rear gate assembly opens to let water flow out of the aqueduct assembly. A method for diverting water is also provided. A front gate assembly opens for allowing water to flow into the aqueduct assembly. Subsequently, rear gate assembly opens for permitting water to flow out of the aqueduct assembly. | 10-07-2010 |
| 20100260547 | Method For Injecting Surface Water Into The Ground - A method and pumping/drainage channel member for injecting surface water into the soil beneath a ground area includes drilling a series of holes and inserting an elongated pumping/drainage members into each hole extending downwardly into the soil. The pumping/drainage channel members comprise a cluster of integrally joined channel features each formed with a lengthwise extending slot opening. Surface water flows to the pumping/drainage member, enters the channels and drains down the pumping/drainage members to enhance water movement down into the soil to reduce runoff and help to recharge acquifers. Longer members may be installed between shorter members in a pattern to achieve more rapid injection of water deep into the subsoil. | 10-14-2010 |

| 20110110719 | DRAINAGE CHANNEL FOR LIQUID RELOCATION AND LINER THEREFOR - Embodiments of the present invention include a drainage channel comprising a first barrier for containment and a second barrier for containment. In one embodiment, the second barrier comprises a liner and a support. In a further embodiment, the support substantially secures at least a portion of the second barrier in the first barrier. | 05-12-2011 |
| 20130078037 | DEBRIS FLOW DRAINAGE CANAL BASED ON CASCADE ANTISCOUR NOTCHED SILL GROUP AND APPLICATION THEREOF - A system of debris-flow drainage canal with cascaded sills is provided, which allows a high-efficient and low-cost realization of debris flow drainage and scour prevention. The canal contains two converging walls and a series of scour prevention sills, which are laid between the two converging walls. The sills are embedded to a certain depth and are evenly spaced and symmetrical to the centre line of the canal to form a cascaded structure for scour prevention. The drainage canal's width is 2 times wider than the sill's horizontal length along the cross-section. Compared with the prior art, this system can drain off a wide variety of flows from debris flow to flood and prevent debris-flow siltation even on a gentle slope. This system has a much higher stability and longer life of service. Moreover, this system can maintain the aquatic habitat in gullies and contribute to ecological restoration. | 03-28-2013 |
| 20140056644 | SYSTEM FOR CONTROLLING RAINWATER RUN-OFF - A system for controlling rainwater runoff, comprising:

| 20150345091 | METHODS OF MARSH RESTORATION VIA RESUSPENSION OF SEDIMENT - Methods for restoring tidal areas adjacent to a tidal water area are provided. The method can comprise: pumping water from the tidal water area; and directing a high-pressure water stream, using the water pumped from the tidal water area, to the bottom surface of the tidal water area during an incoming tide period. The high-pressure water stream impacts the bottom surface of the tidal water area with sufficient force to dislodge sediment from the bottom surface into the tidal water area. | 12-03-2015 |

| 20120294677 | PUMPED VERTICAL DRAIN - A vertical drain for consolidating soil, the drain comprising an elongate surrounding filter jacket having a proximal end and a distal end; and a suction tube having at least one suction aperture located within the jacket, wherein, in use, a suction pump connected to the suction tube is operable to pump flowable material through the suction tube. | 11-22-2012 |
| 20150093198 | INLET OF UNDERGROUND RESERVOIR HAVING MULTIPLE-STAGE STRUCTURE - According to one aspect of the invention, an inlet of an underground reservoir having a multiple-stage structure includes: a flow portion, wherein water flowing in the flow portions; a drop portion transporting the water to a underground reservoir from the flow portion; and an inlet portion having a multiple-stage structure to generate a vortex in the water to be transported to the drop portion. | 04-02-2015 |
| 20160024778 | RETROFIT CATCH BASIN FOR USE IN STORM WATER MANAGEMENT PRACTICE - A catch basin retrofit that allows stormwater to be diverted from an existing storm sewer to an alternative stormwater management practice (SMP), while maintaining functionality of the catch basin as an overflow device for the alternative SMP. | 01-28-2016 |
| 405041000 | Riser or standpipe outlet or intake | 2 |
| 20110064521 | Farmable water quality inlet for transporting water from surface to drainage pipe - A water inlet for transporting water that comprises an elongated body having a center portion formed with a plurality of radially projecting spokes and an exterior portion extending the length of the body and formed of spaced apart strips, with each of the strips fixed on the outer end of one of the spokes to define a plurality of longitudinally extending channels in the body. | 03-17-2011 |
| 20110070027 | System for draining land areas through the use of a venturi apparatus from a permeable catch basin - A principal catch basin defining a certain storage capacity, the catch basin situated below the level of the ground, having an upper level opening for receiving surface water drainage thereunto, and having side walls partially constructed of permeable geotextile fabric for allowing water flow into the permeable basin to serve as a collection for sub-surface drainage. The system would include the ability to automatically pump the drainage water out using the energy of a pressurized water system in conjunction with a venturi pump without the need of any electrical sensors or signals. In addition, there may be a plurality of collection basins which could be joined together as a system to pump the water from various locations through one transport line. | 03-24-2011 |
