Management Plan for a Septic Tank and Soil Absorption Component assessment, maintenance personnel shall 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 service and assessment shall be sealed watertight upon the completion of service. Any opening deemed unsound.diveor subject to failure must be replaced. Exposed access openings greater than&inches in diameter shall be secured by an effective loddng 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 intedor+of the tank may be difficult 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 bngevity of a sod absorption component depends greatly on proper and timely maintenance, and system use within or below the Cnrft of reliable operation. Good water conservation practices by all occupants and the installation of water conserving plumbing fixtures are key factors in exdendiing the useful We of this component. The soil absorption components operation must be assessed by inspection at least once every three years. The inspection shoo i viude recorduig 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 ofsnow 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.
