  • Patent number: 8056629
    Abstract: A system is disclosed for supplying water to a desalination plant from a subsurface feedwater supply using one or more slant wells. A method is disclosed for constructing a slant well feedwater supply system for supplying water from a subsurface feedwater supply. A system of angled wells (slant wells) is constructed. The slant wells obtain a desalination feedwater supply from permeable aquifer systems near and/or beneath a saline water source (i.e., an ocean, sea, or salty inland lake). The slant wells induce recharge of the aquifer system through the floor of the ocean, sea, or inland lake due to the hydraulic head difference between the slant well pumping level and the level of the ocean, sea, or lake. As the supply source is relatively constant, the water supply to such a slant well system generally provides a long-term, sustainable water source for a desalination plant.

  • Patent number: 7918996
    Abstract: The invention is a particle and sediment filter for stormwater. A long permeable filter bag is laid out horizontally within an enclosure. The bag is formed of at least two layers of parallel tubes that give each layer the pleated look of a typical air mattress. Stormwater is collected from the filter bag by perforated pipes held within the creases between the tubes of the layers of the bag, with the pipes draining to the outside of the enclosure. The bag is also supported above the bottom of the enclosure by additional perforated pipes located within the creases between the tubes, thus allowing the filtered liquid to also drain off beneath the bag. The stormwater input is from a pipe that feeds a manifold formed in the bag and connected to each tube. The top of the enclosure is removable for replacing the filter. The filter bags are constructed of flexible material so that they are flat during initial transport and installation, but they expand as they are filled with liquid and solid material.

  • Patent number: 7857547
    Abstract: A gravelless drainfield and drain panel product for all legal gravity and pressure dosed drain configurations for trenches, beds, mounds and elevated systems and foundation and other drain panel applications. The product allows for appropriate reduction in drainfield sizing. Individual pieces of expanded polymer aggregate with three or more fingers are connected where they touch to form a variety of rigid porous panels and blocks of randomly disposed, interconnected, high-surface-area, high-void space elements of light weight expanded polymer material. For the drainfield product, a main pipe for gravity, low-pressure dosing, or drip irrigation receives a flow of liquid in the form of wastewater effluent, gray water, irrigation water or run-off and is held in place by a positioner. A drain panel may be placed against a structure for structural drainage.

  • Patent number: 7815395
    Abstract: A subsurface drainage assembly for directing fluid drainage from a surface is disclosed. The subsurface drainage assembly includes a plurality of drain structure panels that include a plurality of spaced apart tubular support members arranged to define a unit having a plurality of side edges, the tubular support members having a first end, a second end, and a sidewall extending there between. The drain structure panels further include at least one strut extending from each support member to another support member to latterly support the tubular support members. An anchor plate is positioned between at least two tubular support members. The anchor plate has an aperture formed there through sized and configured to receive a ground anchoring member for securing the drain structure panel to a ground surface.

  • Patent number: 7798746
    Abstract: An ornamental planting landscape irrigation distribution and reservoir product and method ecosystem employing a substantially continuous panel on the soil surface on which ornamental landscape plantings are placed or produced, the panel having a primary, lateral water distribution structure which distributes water from a water charging inlet through the lateral area to the panel periphery, where it is restrained, the primary water distribution structure being such that when filled with water or completely submerged in water, air is trapped by the gaps and spaces of the material for ornamental landscape plant usage.

  • Patent number: 7762740
    Abstract: By providing an easily transported, filler component system, leaching field forming elements for establishing a series of flexible design passageways into which the desired fill material is placed, a highly effective, easily installed, competitively priced with enhanced biological habitat underground fluid distribution system is achieved. In accordance with the present invention, the desired passageways are quickly and efficiently created by employing pre-folded cardboard panels, or other pervious materials, placing the materials in an excavated location or site in cooperating relationship with each other for creating the desired leaching fields. In the preferred embodiment, two, substantially identical, pre-folded cardboard panels are employed and are positioned in juxtaposed, cooperating, spaced, facing relationship with each other, establishing a central passageway therebetween.

  • Publication number: 20100150654
    Abstract: Provided is an aquifer replenishing pavement formed above soil having a sand lens above the aquifer and a clay layer above the sand lens. The pavement includes an aggregate leach field having an aggregate top surface, and an aggregate bottom surface abutting the clay layer. The pavement further includes a pavement layer having an exposed pavement top surface, and a pavement bottom surface abutting the aggregate leach field. A surface drain extends through the pavement layer to drain fluid from the exposed pavement top surface to the aggregate leach field. An aggregate drain extends from the aggregate leach field into the sand lens through the clay layer to drain fluid from the aggregate leach field into the aquifer. A filter is disposed within one of the surface drain and the aggregate drain. The filter is configured to remove foreign particulates from fluid passing therethrough.

  • Patent number: 7699557
    Abstract: A concrete structure for replenishing an aquifer and a method for constructing the same is provided. The structure is comprised of a pavement layer with surface drains that extend through the pavement layer and into an aggregate leach field. The leach field includes leach lines spanning the leach field. An aggregate drain extends from the leach field into a sand lens. Precipitation which falls upon the structure thus flows through the surface drain, absorbed into the aggregate leach field, and transported to the aggregate drains by way of aggregate leach lines. The water is then absorbed into the sand lens, ultimately replenishing the aquifer. Existing conventional pavement structures are retrofitted by the removal of a section of the pavement, and filling the same with porous concrete.

  • Patent number: 7632408
    Abstract: A passive drain field assembly reduces nitrogen in wastewater by facilitating nitrification and denitrification. A first chamber receives effluent into a multi-pipe bundle. An air vent is provided that extends from the atmosphere into the first chamber. A second chamber receives effluent from the first chamber, and contains a medium, beneath which is positioned a drainage pipe for releasing treated effluent into the soil therebeneath. A berm creates a retention area in the second chamber that is lined with a water-impermeable liner. In use, ammonia present in the effluent is converted to nitrate in the presence of the oxygen admitted by the air vent in the first chamber. The liquid retained upstream of the berm and above the liner undergoes anaerobic reactions. The remaining liquid proceeds to a place in the second chamber from which the drainage pipe can be entered, from which the treated wastewater can enter the soil.
