Vey Management Plan for a Septic Tank and Soil Absorption Comp nent time of an assessment, maintenance personnel shall advise the owner of wh n the next service needs to be performed to maintain less than maximum scurn and sludge ac mutation in the tank. Manhole risers, access risers and covers should be inspected for we r tightness and soundness. Access openings used for service and assessment shall be sea ed watertight upon the completion of service. Any opening deemed unsound, defective, or subj ct to failure must be replaced. Exposed access openings greater than 8-inches in diameter st all be secured by an effective locking device to prevent accidental or unauthorized entry into tt e tank. No one should enter a septic or other treatment or holding tank for any reason without being/n full compliance with OSHA stano fards for entering a confined space. The atmosphere within the septic or other treatment or holding tank may contain lethal gases, and res cue of�a person from the interior of the tank maybe difficult or impos ible. Tank abandonment shall be in accordance with Comm 133.33, Wis, A Jm. Code when the tank is no longer used as a POWTS component. Soil Absorption Component The soil absorption component serving this structure) is designed to g ccept domestic wastewater from a residential facility. The limits of operation of this compon Brit are shown in Table 2. The longevity of a soil absorption component depends greatly on prc per and timely maintenance, and system use within or below the limits of reliable operation Good water conservation practices by all occupants and the installation of water consery ng plumbing fixtures are key factors in extending the useful life of this component. The Soil absorption component's operation must be assessed by Inspection at least once every three years. The inspection shall include recording the levels of ponding, if any, in the observation pipes, and a visual inspection for any evidence of surfaceseepage or discharge from the component. On steeply sloping sites, areas of erosion should bei entified and reported to the owner for repair. The surface discharge of domestic waste ter or sewage from the system is prohibited and considered a human health hazard. Traffic around or over the soil absorption component should be avbic ed particularly during winter months. The compaction or removal of snow cover over the c mponent may lead to hydraulic failure by freezing. This type of failure Is usually temporary, but is difficult or impossible to repair until weather conditions improve. In general, roil comp ction over this component will reduce diffusion of oxygen into the soil and dispersal cell, w ich may lead to more intense, and earlier, organic clogging of the soil. Plantings of deep-rooted trees and shrubs directly over or within ten eet of the component should be avoided since root intrusion into the component may bstruct wastewater flow. 2
