Mainline pipes, lateral pipes, and wire sleeving are installed within a common trench surrounded by bedding material and clean backfill compacted to ninety percent. A minimum clearance of two inches is maintained between pipes, with wire routed beneath and beside the mainline and taped and bundled at ten-foot intervals. All solvent weld plastic piping is snaked within the trench. A twenty-four-inch slack loop is tied in all wiring at direction changes of thirty degrees or greater and untied after all connections are complete.
