Adm Code,and the appropriate Soil Absorption Component Manual for Private Onsite Wastewater Systems. The specific component manual for this POW T.S. is: Table 1:System Design Specifications Sanitary Permit Number: Septic Tank Capacity(gal)./AX) Number of Bedrooms: 3 Dose Tank Capacity(gal): Design Flow-Peak(gpd): Ae`_V Soil Absorption Component Size (Sc. Ft.): 1346 Estimated Flow-Average(gpd): Type of Wastewater: Domestic Table 2: Soil Absorption Component•Limits of Reliable Operation Septic Tank Soil Absorption Component Component Design Flow-Peak (gpd) Maximum Influent Particle Size(in) n/a 1/8 Maximum BOD (mg/L) n!a 220 Maximum TSS (mg/L) n/a 150 Maximum FOG n/a 30 Table 3: Maintenance Schedule Septic Tank Inspect and/or service every 3 years. Outlet Should inspect once a year and clean once every 3 years. Soil Absorption Component Inspect once every 3 years. Contingency Plan: Use alternate site if available or remove distribution pipe,aggregate or chambers&clogging mat.. Replace distribution pipe, aggregate or chambers&C-33 fine aggregate. Septic Tank The septic tank shall be maintained by an individual certified to service septic tanks under s. 281.48. Stats. The contents of the septic tank shall be disposed of in accordance with NR 113. Ws.Adm.Code(Servicing Septic or Holding Tanks. Pumping Chambers. Grease Interceptors. Seepage Beds. Seepage Pits. Seepage Trenches, Privies. or Portable Restrooms). The operating condition of the septic tank and outlet fitter shall be assessed at least once every 3 years by inspection.The outlet fitter shall be cleaned as necessary to ensure proper operation.The filter cartridge should not be removed unless provisions are made to retain solids in the tank that may slough off the fitter when removed from its enclosure. It the filter is equipped with an alarm.the filter shall be serviced it the alarm is activated continuously. Intermittent filter alarms may indicate surge flows or an impending continuous alarm.The septic tank shall have its contents removed when the volume of scum and sludge in the tank exceeds 113 the liquid volume of the tank.It the contents of the tank are not removed at the time of 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. 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 difficult or impossible. Tank abondonment shall be in accordance with Comm 83.33. Wis. Adm. Code when the tank is no longer used as a P.O.W.T.S. component. Dose Chamber Notice that the dose chamber may fill due to flow continuing during pump malfunction or power outages.One large dose when the power comes on or when the pump is repaired may cause the mound component to have problems. In this situation.the pump chamber should be pumped by a licensed pumper before pump cycling begins or other measures shall be used to dose the mound component with only the proper amount of influent.This may include manual operation of the pump controls until such time the pump chamber has reached its normal level. Dose chambers are to be inspected routinely and maintained when necessary in accordance with their approvals. 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 component's operation must be assessed by inspection at least once every three years. The inspection shall include recording the levers of ponding, it 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 indeniffied and reported to the owner for repair. The surface discharge of domestic wastewater or sewage from th 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 componew wit reduce diffusion of oxygen into the soil and dispersal telt. which may lead to more intense. and earlier. organic 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 Distribution Network Partial plugging of the distribution network may be detected by extremely long dosing time. The ends of the distribution laterals should be exposed and the pump activated to flush out any solid material. The liquid that is flushed out of the laterals is to be directed back into the distribution cell or into an acceptable container. It necessary, the laterals can be cleaned.
