Wastewater leaching chamber
Wastewater leaching chambers and leaching channels are disclosed. The chambers may include a recess for receiving a wastewater supply, the recess serving to lower the overall height of the combined chamber and supply. The recess also configured to tightly seat the supply and form a gap therebetween. Leaching channels having a high aspect ratio may also be coupled to or otherwise in fluid communication with the chamber.

a wastewater supply conduit comprising a plurality of wastewater discharge orifices, the wastewater supply conduit sitting in the recess of the leaching chamber, the discharge orifices positioned to discharge into a gap created by the mating of the wastewater supply conduit and the recess, the gap at least in part protected from soil infiltration by the mating of the wastewater supply conduit and a surface of the recess.
2. The wastewater treatment system of claim 1 wherein the wastewater supply conduit is a circular pipe and the recess has a depth of at least 9/10 the diameter of the wastewater supply conduit.
3. The wastewater treatment system of claim 1 wherein the leaching chamber comprises concrete and the recess is in a “V” shape.
4. The wastewater treatment system of claim 1 wherein the leaching chamber has a length and the mating of the wastewater supply conduit and the recess runs along at least a portion of the length of the leaching chamber.
5. The wastewater treatment system of claim 1 wherein the leaching chamber has an overall exterior shape that is circular, semicircular or rectangular or square.
6. The wastewater treatment system of claim 1 wherein the leaching chamber is comprised of plastic.
7. The wastewater treatment system of claim 1 wherein the wastewater supply conduit comprises a plurality of circular discharge orifices having diameters of at least one of ⅛″ or ¼″ or ½″ or ¾″ or 1″ and wherein the wastewater supply conduit is gravity fed or pressurized or both.
8. The wastewater treatment system of claim 1 further comprising:
a plurality of leaching channels, the leaching channels extending outwardly from one of the walls of the leaching chamber, the leaching channels each comprising an outrigger support, and each of the leaching channels having a height to width aspect ratio of 3, or 96, or between 3 and 96.
9. The wastewater treatment system of claim 8 wherein each of the leaching channels comprises a geotextile fabric surrounding a majority of the leaching channel.
10. The wastewater treatment system of claim 9 wherein the geotextile fabric positioned to interface with a surrounding medium when the leaching chamber is installed and operational.
11. A wastewater treatment system comprising:
a leaching chamber with one or more upright wall(s), a top portion, and an open-bottom chamber, the top portion configured with an externally exposed wastewater supply receiving recess, the recess having one or more passages configured to receive wastewater from a wastewater supply conduit positioned in the recess and to pass the received wastewater through at least one of the passages and into the chamber;
a wastewater supply conduit with a plurality of wastewater discharge orifices, the wastewater supply conduit sitting in the recess of the leaching chamber, the discharge orifices positioned to discharge into a gap created by the mating of the wastewater supply conduit and the recess, the gap at least in part protected from soil infiltration by the mating of the wastewater supply conduit and a surface of the recess; and
a plurality of leaching channels, the leaching channels extending outwardly from at least one of the walls of the leaching chamber, the leaching channels each comprising an outrigger support, and each of the leaching channels having a height to width aspect ratio of 3, or 96, or between 3 and 96.
12. The wastewater treatment system of claim 11 wherein the leaching chamber comprises concrete and the outrigger support comprises a pipe.
13. The wastewater treatment system of claim 11 wherein the leaching chamber includes one or more tie down anchors, the anchors accessible and positioned to receive a tie down element for securing the wastewater supply conduit into the recess.
14. The wastewater treatment system of claim 11 wherein the plurality of leaching channels comprise a geotextile outer perimeter, the geotextile serving as an interface for wastewater leaching from the leaching channel into any surrounding Infiltration and Treatment Medium (ITM).
15. The wastewater treatment system of claim 11 wherein the recess has a sloped portion and a curved portion.
16. The wastewater treatment system of claim 11 wherein the recess has a first curved portion and a second curved portion, the second curved portion sitting below the first curved portion and the second curved portion having a radius of curvature that is smaller than the first curved portion.
17. A wastewater treatment system comprising:
a leaching chamber with one or more wall(s) and a top portion, the top portion configured with an externally exposed wastewater supply receiving recess, the recess having one or more passages configured to receive wastewater from a wastewater supply conduit positioned in the recess and to pass the received wastewater through at least one of the passages and into the chamber;
a wastewater supply conduit with a plurality of wastewater discharge orifices, the wastewater supply conduit sitting in the recess of the leaching chamber, the discharge orifices positioned to discharge into a gap created by the mating of the wastewater supply conduit and the recess, the gap at least in part protected from soil infiltration by the mating of the wastewater supply conduit and a surface of the recess; and
a plurality of leaching channels, the leaching channels extending outwardly from one or more of the walls of the leaching chamber.
18. The wastewater treatment system of claim 17 wherein the leaching chamber comprises concrete.
19. The wastewater treatment system of claim 17 wherein the leaching chamber includes one or more tie down anchors, the anchors accessible and positioned to receive a tie down element for securing the wastewater supply conduit into the recess.
20. The wastewater treatment system of claim 17 wherein the plurality of leaching channels comprise a geotextile outer perimeter, the geotextile serving as an interface for wastewater leaching from the leaching channel into any surrounding Infiltration and Treatment Medium (ITM).
