Other activities such as excavating or filling, driveway placement, <br /> paving or other similar activities that alter the natural soil conditions will adversely affect the soil and <br /> the septic system function and lead to premature system failure. The area must not be subjected to <br /> excessive saturation due to artificial drainage of ground surfaces, driveways, building downspouts or <br /> other sources.The areas of the initial septic system and the future repair system must both be protected. <br /> THIS SYSTEM MUST BE INSPECTED AND APPROVED PRIOR TO BACKFILL.
