Confirm overflow relief gully position, terminal vents, level inverts per AS 3500, number of downpipes, soak holes or tanks, and water testing. Include septic tank installation, effluent field, distribution box, and trench dimensions. Supports engineer PS4 sign off and records pass or fail outcomes, including local requirements such as catchpits for large paved areas.
