Soil absorption module for effluent dispersal system

A vertical sidewall effluent dispersal system adapted for placement in a trench, said system comprising:

• a plurality of soil absorption modules connected in series, each said soil absorption module comprising:
• A) a conduit segment extending between upstream and downstream ends, an orifice in said conduit segment disposed between said upstream and downstream ends,
• B) an elongated grid body disposed substantially in alignment below said conduit segment, said grid body having a first flanking side and an opposite second flanking side, said first flanking side comprising a plurality of horizontal steps and a plurality of vertical dividers arranged in a rectilinear pattern, said second flanking side comprising a plurality of spreader fins diagonally crisscrossing one another in a diamond pattern, said horizontal steps and said vertical dividers overlapping said spreader fins at an interior switch-back zone configured to direct effluent laterally back-and-forth in a downward and longitudinally spreading propagation, and
• C) a geotextile envelope surrounding said conduit segment and said grid body,
• and wherein each said soil absorption module is isolated from the next adjacent soil absorption module by an earthen barrier.
