Appendix G Drawings Fig. 1 The slope across the drain field starting from the first line to the last line is < 6 inches. The outlet flow line of the septic tank is at or above the highest ground elevation within absorption area. Distribution box height is not critical. Fig. 2 Elevation change from the first line to last line is ≥ 6 inches. Outlet flow line of D-box is at or above the ground elevation of the highest line of the absorption area. Figure 5 Capping Fill System - Side View (Less than 6% Slope) Location of the distribution box or septic tank outlet determined by the fall across the absorption field. See 14 CAR § 21-807 (e) and 9.11.6 Distribution Box Septic Tank Note: Capping material must extend 10 ft. from trenches before the start of the slope. The tapered slope shall be 3:1 or less.
