The seasonally saturated soils were located at 18"-24"{mottled soil). Due to the seasonally sat�ated soils, a pressurized Mound System will need to be installed to treat septic effluent The bottom of the treatment area must be located ai least 3'above the satorated soiLs. The soils at a depth of 12"have a percolarion rate averaging 8 MPI. All neighboring wells are greater than 100 feet from pmposed treatment areas. The eacisting ta�slc may be used upon approval of the local inspector. All new tanks need to be insulated if less than two feet deep and a fiiter installed on the second tank.Clean outs must be installed on the end of the laterals for maintenance. A pumping chamber will need to be installed to lift the effluent to the trealment area. The gower supply and switches must be located outside the raanhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with a light and sound device;this is in case of a pump failure. Keep ail heavy eguipment off of the proposed treatment areas before and after construction. T6e treatment area must be fenced off before constrnction begins. This Design is not valid&the System will need to be relocated if failare to protect the aress proposed for the On-Site Sewage Treatment systems occurs. Nothing other than gray water,{isundry,showers,ec�)human water&toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Additives must no be used,they may cause harmful damage to your septic system. It is recommended that you pump the septic tanks every two years. t��oRoxc� Sincerely, ��p��p � �%' TI�ISPECTUA / � ��, AAT �mov��s suahnrn� � doseph J.Olson ��. �� AArytpvEp wi'ffi CORR6C'AON�Ai pQ!'� N(n'M�RUYEI�CORR6t.7��11tl� 1be�o�oa+ma�b w�x qar�bl w�d rMrM iir� 1�!Wl e�npii�t�SU�It p►pNMb1��Mt s�do�o�Ai► R�Iraiud�Naru�aat y�iti�jr raa�bfYi►N1M�, Xii'i8P3'ipi��i iiCf'i�liHT1tAT Ai�.'� � . _ � ' � � STu�3t3S I��1' �,r�i� /�1 - , aG , 3 � h . - S � e !
