An irrigation trench runs beneath paving and earth surfaces with a main line and sleeved lateral pipes embedded in sand backfill. Control wires are housed in PVC electrical sleeves under paving and taped to the main line every ten feet. Depth dimensions of twenty-four, thirty, and thirty inches apply to the trench profile, with six-inch clearances specified between utility lines. The assembly incorporates base material layers, earth surfaces, and designated pavement zones.
