Leach field system

A system for wastewater comprising:

• a plurality of channels, each channels of the plurality having a height to width aspect ratio in a range of as high as 96 and as low as 3, and having an uppermost surface,
• the channels of the plurality being substantially parallel and having a length of substantially one foot or more,
• at least two of the channels being interconnected to each other below their uppermost surface,
• the channels of the plurality each comprising an upright infiltrative surface, where the upright infiltrative surfaces of adjacent channels are separated along a majority of their lengths by two or more inches and each have a spacing of one foot or more along their length without an intersecting infiltrative surface that connects the adjacent channels within the spacing;
• and
• a wastewater distribution conduit, the distribution conduit positioned such that an area of the conduit having wastewater supply egress openings, traverses a majority of the channels of the plurality at an oblique or perpendicular angle and traverses separations between adjacent channels of the plurality at an oblique or perpendicular angle, the separations between adjacent channels of the plurality comprising
• a void comprising the majority or all of the space of the separation,
• or sand,
• or a granular material.

A system for wastewater comprising:

• two opposing upright substantially parallel infiltrative surfaces, where a first infiltrative surface borders on a first channel and a second infiltrative surface borders on a second channel,
• the first channel and the second channel having a height to width aspect ratio in a range of as high as 96 and as low as 3,
• the first channel having an uppermost surface,
• the second channel having an uppermost surface, and
• the first channel and the second channel being interconnected to each other at least below their uppermost surface,
• wherein the opposing infiltrative surfaces each have a length of one foot or more,
• wherein the opposing infiltrative surfaces are separated along a majority of their length by two or more inches,
• wherein the separation between opposing infiltrative surfaces is not comprised of the first channel or the second channel and comprises a void occupying at least the majority of the volume of the separation;
• and
• a wastewater distribution conduit with wastewater egress openings, the distribution conduit positioned such that the area of the conduit having wastewater egress openings traverses the opposing infiltrative surfaces at an oblique or perpendicular angle and traverses the separation between the opposing infiltrative surfaces at an oblique or perpendicular angle.
