American Water Works Association Trenching should be completed in existing soils with sidewalls reasonably vertical to the top of the pipe. For positive projection embankment installations, the embankment material should be placed and compacted to a minimum of one foot above the pipe and the trench excavated into the embankment. Test pattern is to begin after the first 4 lift above bedding and continue to 1 foot above top of the pipe. 11) Backfill depth is at least equal to the diameter of the pipe.
