The bottom <br /> of the h�eatment area must be located at least 3' above the saturated soils. <br /> The soils at a depth of 12"have a percolation rate averaging 8.4 MPI. <br /> All tanks need to be insulated if there is less than two feet of cover over the top of the tanks.A filter needs <br /> to be installed on the second tank. Clean outs must be installed on the end of the laterals for maintenance. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area.The power supply and <br /> switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A <br /> warning device must be installed with a light and sound device;this is in case of a pump failure. <br /> Use 7/32 inch perforations on the laterals. <br /> Keep all heavy equipmeot off of the proposed treatment areas before and after construction.The <br /> treatment area must be fenced off before construction begins.This Design is not valid&the System <br /> will need to be relocated if failure to protect the areas proposed for the On-Site Sewage Treatment <br /> systems occurs. <br /> Nothing other than gray water,(laundry,showers,ect.)human water&toilet tissue should be disposed of <br /> into the septic tanks.Garbage disposals are not recommended. Additives must not be used;they may cause <br /> harmful damage to your septic system.It is recommended that you pump the septic tank every year for 1 <br /> tank,every two years for two tanks. <br /> Sincerely, <br /> � <br /> �', <br /> -;.- ��.._ ..�-._ _ CITY OF ORONC) <br /> Joseph J.Olson SF.PTIC P MIT `f�EV - <br /> INSPEC O <br /> DAT " PERMIT NQ. <br /> APPROYCD AS 91:I3�tiT7'Ep <br /> � APPROVGp WITH CORRECTtOn9 AS NOTED <br /> NOT APPROVEU-CORRECT&RBSL'6411T <br /> 'Chcse comments are for your informativa.
