Rule 15-18-77-5.6.15 - Distribution System Specifications1. The distribution system in an elevated sand mound shall consists of three components: a. a pressurized distribution manifold- that shall consist of a small diameter (1"- 1.5") schedule 40 pipe, to receive the effluent from the pump. This pipe shall be connected as to not create any dead ends, and shall have 3/8" holes drilled in it every 36" pointing up. See Figures 2 and 3. The effluent from the pump must come to the center of this distribution manifold and absorption area.b. field drain pipe to house the pressurized distribution manifold- A 4" field line pipe with the holes pointing down is acceptable. Other field drain pipe designs may be acceptable, but first must go through the experimental protocol.c. distribution media- -" to 2.5" gravel to a depth of 1' is acceptable. The design of the absorption area must comply with design guidelines for gravel underground absorption. If other distribution media is approved, they must comply with the appropriate regulations and guidelines.d.Figure 2: SIDE VIEW OF DISTRIBUTION SYSTEM IN ABSORPTION AREA OF AN ELEVATED SAND MOUNDe.Figure 3: TOP VIEW OF ABSORPTION AREA WITH DISTRIBUTION NETWORK AND FIELD LINE PIPE.15 Miss.
