Y r at the ti a of an assessment,maintenance personnel shall advise the owner of when the next service needs to be performed to maintain less than the allowable maximum scum and sludge accumulation in the tank. Manhole risers,access risers and covers must be inspected for water tightness and soundness. Access openings used for ervice and assessment shall be sealed watertight upon the completion of service. Any opening deemed not watertig t,defective,or subject to failure must be repaired or replaced. Exposed access openings greater than 8-inches in diamete 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 of holding tank may contain lethal gases, and rescue of a person from the interior 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. LL • OUTLET FILTER The outlet filter of the primary treatment tank shall be cleaned as necessary to ensure proper operation. The filter cartridge must not be removed unless provisions are made to retain solids in the tank that may slough off the filter when removed from its enclosure. If the filter is equipped with an alarm,the filter shall be serviced if/when the alarm is activated continuo�rsly. Occasional short duration filter alarms may indicate surge flows or an impending continuous alarm. 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 article II of this document. 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 component's operation must be assessed by inspection at least once every three years. The inspectio�t 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. The inspection shall be conducted by a properly licensed individual in accordance with ch.Comm 5,and the report of findings shall be submitted to Dane County Environmental Health w,'thin 10 working days after the inspection. On steeply sloping sites,areas of erosion must be identified and reported o Dane County Environmental Health and to the owner. The surface discharge of domestic wastewater or sewage from the system is a human health hazard and must be reported to Dane County Environmental Health if it is observed at the time pf inspection. Traffic around or over the soil absorption component should be avoided particularly during winter months. The compact n or removal of snow cover over the component may lead to hydraulic failure by freezing. This type of failure is usually t mporary,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,o ganic clogging of the soil. 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. III. METERING,SAMPLING AND MONITORING SCHEDULES A. Treatment Tank:Metering and sampling are not required unless specified by the manufacturer. Monitoring includes inspection for accumulated solids and for defects at least once every three years. B. Outlet Filter: The outlet filter must be monitored according to manufacturer's instructions(attached),or whenever the alarm is continuously activated. C. Dosing Chamber: Metering and sampling not required unless specified by the manufacturer or the design plan. Monitoring includes inspection for accumulation of solids and for defects at least once every three years. Pump and controls are to be inspected for proper performance at least once every three years or when the alarm is continuously activated. to. Soil dispersal or treatment cell: Metering and sampling are not required unless specified in the design plan or is required by the local unit of government. Monitoring must be conducted at least once every three years or as specified in design plan. Inspection must include evaluation of any compacted surfaces over the
