THE ATTACHED SEPTIC TANK ABANDONMENT FORM MUST BE COMPLETED AND RETURNED TO OUR OFFICE. The septic system installer must complete and sign the form and attach a copy of the receipt from the septic tank pumping service for pumping the tank. MAINTAIN PERMANENT ACCESS to septic tank for pumping and service. The septic tank should be pumped and inspected by a licensed septic tank service before sludge and scum accumulations reach 30%of the tank liquid operating volume. Pumping every 3 to 5 years is an average interval. The septic tank is a reservoir for the solid materials in the sewage waste stream. Excessive accumulation of these solid materials in the septic tank will cause the solids to wash out of the tank and into the drainfield. This will cause irreversible damage to the drainfield and will eventually lead to a system failure. THE APPROVED SEPTIC SYSTEM AREA MUST BE PROTECTEDfrom any vehicular traffic or other sources of soil compaction. Activities such as excavating or filling,driveway placement,paving or any similar alteration of the natural soil conditions will adversely affect septic system function and lead to premature system failure. The area must not be subjected to excessive saturation due to artificial drainage of ground surfaces,driveways, building downspouts or other sources. The areas of the initial septic system and the future repair system must both be protected. 7/16/18:12:17:34PM Page 2 of 3 ONS_OnsitePermit_pr
