MAINTAIN PERMANENT ACCESSto 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. 6/3/19:9:51:57AM Page 3 of 4 ONS_OnsiteCSCpr
