Figure 5 — Minimum Setbacks from Downslope Feature modulars house 0-9 Figure 6 — Typical Glendon® Model M31 System Layout Multiple unit systems should be designed to facilitate dispersing the treated effluent over a broad area. For example, two rows (lines) of three basins each oriented on the contours is better than "stacking" three rows (lines) of three basins each oriented on the contours (each basin normally has its long side perpendicular to the direction of the slope). When the site characteristics require "stacking" the primary units should be laid out in a checkerboard (alternating) fashion rather than selecting units immediately down gradient.

Any deviation from these conditions renders these calculations invalid. c V_ 1D 10A 5' C fi.CUL�-tOC� BasinF OC cOt15 V 77 NCO U 19' 100% Primary Cross Section through Basin Perpendicular to Slope 14.5 Down Slope USDA Type Soil 182 3 4 5 6 Dimension Soil Load Rate Gal. /Ft2 /Day 1.2 0.8 0.6 0.2 50% Abs.
