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.

Abstract: A leaching chamber for gathering and dispersing liquids in soil has an end with an angled terminus, so that chambers may be connected as a string in a rough curve. An angled chamber end is severable from the chamber at an indicant, to convert the chamber to one having a different angled end, e.g., a square end. Intentional looseness of fit at the joint enables further angular adjustment. Thus, a combination of chambers with original and severed ends, having a basic 6 degree end angle and 3 degree of looseness, can form a chamber string where the alignment angles between adjacent chamber axes range from minus 3 to plus 9 degrees. Such leaching chamber strings may be installed in practically level trenches which follow the contour of a hillside.

Abstract: An on-site wastewater treatment system distributes septic tank effluent over a particulate media filter bed through a distribution manifold at a sufficient volumetric flow rate relative to the cross-sectional area of the distribution conduits to inhibit undesirable biological growth in the conduits and in the filter by creating a scouring effect in the conduits. This effect prevents clogging of the conduits and maximizes the even distribution of effluent in the filter. A mesh fabric intercepts the downward flow of the effluent in the filter to further aid in the even distribution of effluent in the filter. Orifice shields also aid in such distribution by preventing clogging of orifices embedded in the filter media. A high pressure switch in the distribution manifold and a high water alarm in the filter pump basin indicate when required maintenance is necessary, and the switch controlling the high water alarm temporarily disables the septic tank pump as well.

Abstract: A system and method is disclosed for distributing greywater to a soil bed without significant erosion of the soil bed. An interior tube defining at least one aperture is disposed within an exterior tube. The interior tube and the exterior tube are immersed in a soil bed for aerobic decomposition of greywater discharged from the greywater distribution apparatus into the soil bed. The apertures of the interior tube are sealed from the soil bed when greywater is not being discharged into the soil bed. Directing greywater into the interior tube at a sufficient pressure causes greywater within the interior tube to be directed through the apertures. The exterior tube baffles the flow of greywater through the apertures, thereby diminishing the velocity of the greywater. The greywater then passes between the interior tube and the exterior tube and is discharged from the exterior tube through a slot which extends along a substantial portion of the exterior tube.
