Management Plan for n Seplic; Tank rind Soil Ahsorption Component <br /> time of an assessment, maintenance personnel shall advise the owner of when the next service <br /> needs to be performed to maintain Fess than rriaxirnurn scum and sludge accumulation in the <br /> tank. <br /> Manhole risers, access risers and covers should he inspected for water tightness and <br /> soundness. Access openings used for service and assessment shall be sealed watertight upon <br /> the completion of service. Any opening deemed unsound, defective, or subject to failure must <br /> be replaced. Exposed access openings greater than 8-inches in diameter shall be secured by <br /> an effective locking device to prevent accidental or unauthorized entry into the tank. <br /> No one should enter a septic or other treatment or holding tank for <br /> any reason without being in fell/ compliance with CISHA standards for <br /> entering a confined space. The atnâ–șosph-ere within the septic or other <br /> treatment or holding tank may contain lethal gases, and rescue of a <br /> person from the interior of the tank may he difficult or impossible. <br /> Tank abandonment shall be in accordance with Comm 83.33, Wis. Adm. Code when the <br /> tank is no longer used as a POWTS component. <br /> Soil Absorption Component <br /> The soil absorption component serving this structure is designed to accept domestic <br /> wastewater from a residential facility. The limits of operation of this component are shown in <br /> Table 2. <br /> The longevity of a soil absorption component depends greatly on proper and timely <br /> maintenance, and system use within or below the limits of reliable operation. Good water <br /> conservation practices by all occupants and the installation of water conserving plumbing <br /> fixtures are key factors in extending the useful life of this component. <br /> The soil absorption component's operation must be assessed by inspection at least <br /> once every three years. The inspection shall include recording the levels of ponding, if any, in <br /> the observation pipes, and a visual inspection for any evidence 01surface seepage or discharge <br /> from the component. On steeply sloping sites, areas of erosion should be identified and <br /> reported to the owner for repair. The surface discharge of domestic wastewater or sewage <br /> from the system is prohibited and considered a human health hazard. <br /> Traffic around or over the soil absorption component should be avoided particularly <br /> during winter months. The compaction or removal of snow cover over the component may lead <br /> to hydraulic failure by freezing. This type of failure is usually temporary, but is difficult or <br /> Impossible to repair until weather conditions improve. In general, soil compaction over this <br /> component will reduce diffusion of oxygen into the soil and dispersal cell, which may lead to <br /> more Intense, and earlier, organic clogging of the soil. <br /> Plantings of deep-rooted trees and shrubs directly over or within ten feet of the <br /> component should be avoided since root intrusion into the component may obstruct wastewater <br /> flow. <br /> 2 <br />
