Management Plan for a Septic Tank and Soil Absorption Component assessment, maintenance personnelshall advise the owner of when the next service needs to be performed to maintain less than maximum scum and sludge accumulation in the tank. Manhole risers, access risers and covers should be inspected for water tightness and soundness. Access openings used for servibe and assessment shall be sealed watertight upon the completion of service. Any opening deemed unsound,defective,or subject to failure must be replaced. Exposed access openings greater than 84nches in diameter shall be secured by an effective locking device to prevent accidental or unauthorized entry into the tank. No one should enter a septic or other treatment or holding tank for any reason without being in full compliance with OSHA standards for entering a confined space. The atmosphere within the septic or other treatment or holding tank may contain lethal gases, and rescue of a Person from the interior of the tank may be dhWcult or impossible. Tank abandonment shall be in accordance with Comm 83.33, Wis. Adm. 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 accept domestic wastewater from a residential facility_ The limits of operation of this component are shown in Table 2. The longevity of a soil absorption component depends greatly on proper 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 conserving plumbing fixtures are key factors in extending the useful life of this component. The soil absorption components 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 surface seepage or discharge from the component On steeply sloping sites. areas of erosion should be identified and reported to the owner for repair. The surface discharge of domestic wastewater or sewage from the system is prohibited and considered a human health hazard. Traffic around or over the soil absorption component should be avoided particularly during winter months. The compaction or removal of snow cover over the component 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,soil compaction over this component will reduce diffusion of oxygen into the soil and dispersal cell,which may lead to more intense,and earlier,organic dogging of the soli. Plantings of deep-rooted trees and shrubs directly over or within ten feet of the component should be avoided since root intrusion into the component may obstruct wastewater flow. 2
