BURNETT COUNTY ZONING ADMINISTRATION <br /> BURNETT COUNTY GOVERNMENT CENTER <br /> 7410 COUNTY ROAD K,#102 PHONE(715)349-2138 <br /> SIREN,WISCONSIN 54872 <br /> Inspection Report: System Repair <br /> On December 15,2006,at 2:45 pm,l inspected the repair of a Mound type Private On-site Wastewater <br /> Treatment System at the residence of Mike and Kelly Moritz,at 12431 North Fork Drive, located in <br /> Section 8,T38N R18 W,Town of Wood River.The system had been installed under Sanitary Permit <br /> 445614(Co.#28158)on October 24,2003. Master Plumber Nils Koerper,WS Carl Lippert and I had <br /> previously determined that the holes in the distribution laterals appeared to be plugged. The pump <br /> originally installed had also failed There was no evidence of ponding within the soil absorption cell. The <br /> property owner asserts that the Zabel A-100 septic tank filter has not been removed,and it does not appear <br /> to have floated up,as there has not been a backup into the structure. There also has been a water softener,a <br /> dehumidifier,and condensate from a high efficiency furnace connected to the wastewater system. The soil <br /> cover above the laterals,was carefully excavated by hand,the filter fabric cut,and the aggregate above and <br /> alongside the laterals removed and saved,to be replaced later.The laterals were removed and flushed with <br /> clean water.The 1/8-inch diameter holes were plugged with a durable,brownish gray material,in some <br /> cases containing white flecks. We had observed sludge present within the laterals when they were flushed, <br /> while we were diagnosing the specific problem with the system,however, very little,if any,sludge <br /> remained within the laterals when they were removed. <br /> Corrective Measures <br /> After cleaning the laterals,the holes were re-drilled to 3/16-inch diameter,at the same spacing as <br /> previously approved,and they were reconnected to the manifold within the mound The aggregate was <br /> replaced,and new strips of filter fabric placed over the seams where the laterals had been removed. The <br /> soil cover was replaced,and the area of the cell and part of the adjacent toe covered with hay for insulation. <br /> The failed pump was replaced with a Zoeller 152. This pump supplies more than adequate flow to <br /> accommodate the increased flow rate from the larger hole size in the distribution laterals. <br /> The handle of the Zabel A-100 septic tank filter was to be extended to immediately below the septic tank <br /> manhole cover,to assure that the filter cannot float. <br /> The water softener backwash and dehumidifier have been disconnected from the wastewater system,and <br /> are now being handled as a clear water discharge from a sump that had been installed in the house,but was <br /> not previously in service. The area is suitable for a clear water discharge per Com.82. <br /> Comments <br /> Due to the current`open winter"conditions,and the potential for deep frost penetration,this system will <br /> remain susceptible to freezing in the absence of significant snow cover, for the remainder of this winter. <br /> The repair conducted does appear to have resolved the problem of the blockage of the holes within the <br /> distribution laterals. The property owner has been advised to allow significantly more vegetative cover to <br /> remain on the mound,or add hay or straw,in the 4611,to provide better insulation from frost in the absence <br /> of substantial snow cover. <br /> Date Qj I <br /> Craig Conroy POWTS Inspector Cert.No.70131 <br />
