Excavate the marked area for the septic tank to the required depth. Ensure the hole has straight, clean, and square edges, as this indicates a professional installation. The bottom of the excavation must be precisely leveled and compacted to provide a stable and flat bed for the heavy concrete tank. Use a grade laser or a transit for accuracy. In the absence of specialized equipment, a long 2x4 with a spirit level can be used to achieve a level surface.
