Due to seasonally saturated soils,a pressurized <br /> Mound System will need to be installed to treat septic effluent. The bottom of the treatment area must be located at <br /> least 3'above the saturated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 14 MPI. <br /> Part of the absorption area on the future site for this lot is less than one foot to mottling. <br /> All neighboring wells are located greater than 100'away from proposed treatment area. <br /> Use 7/32 perforations in the laterals. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area The power supply and Switches <br /> must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be <br /> insYalled with light and sound devices;this is in case of a pump failure.The manifold and supply line must have back <br /> drainage to the pumping chambec The distribution pipes shall have their ends eapped. Be sure the rock and sand fill <br /> materials are clean. The sod layer below the entire mounded area must be turned over,just break up the sod and be <br /> sure not to over��ork. <br /> Keep all heavv equipment off of the proposed treatment areas before durinE and after construMion. The area <br /> around the site must be fenced aff by the contractor before anv construction begins.This Desien is not valid and <br /> the Svstem will need to be relocateu if failure to protect the area of the proaosed On-Site Sewaae Treatment <br /> occurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic efllue�t effectivcl�. <br /> Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the <br /> septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause hazmful damage to <br /> your septic system. It is recommended that you pump the tank every year for 1 tank,every two years for two tanks. <br /> Sincerely, <br /> ���� <br /> �/� �`�"!'�'�' ' ,,�������� <br /> Joseph J.Olson �� <br /> D �� � •���MIMA� <br /> ���� <br /> J�"P�QVBD'�!'f�{�OIt1t8C'i'p1i�1lOaj'� <br /> N!)T�1TwtOt+l�p►W1eRi�T#I�t18Mt1' <br /> 1�s�aMroaMr�ee&►r�ip�u� 111�n�1t.I�NiM�i <br /> f�!b!t eom4ttt.eoe�rhk aN�ppNc�ble�it�aa�ia��11► <br /> �teqa�bOaaenp i�ci+d�iWaa�net�fo�r soa�l d111i�►�wlM�k <br /> �E$!''ti�!��#T t�lt�Y�tA���iAtRi <br />
