Due to seasonally saturated soils,a pressurized <br /> Mound System will need to be installed to treat septic ef�luent. The bottom of the treatment azea must be locatcd at <br /> least 3'above the saturated soils.Due to limited space that is on 12%slope or less and one foot to the mottled soil."I he <br /> mound rockbcd must be split into two rock beds.The proposed rockbed are to be 32 Feet in length. <br /> This svstem is desiEned with duel rockbed using unlevel pressure distribution.See design sheets.Use 7/32 inch <br /> �erforations on the laterals. <br /> 1'hc absorption area of the proposed system does not overlap and is greater than 10 feet from the propem fine. <br /> 'I�he s�ils at a depth of 12"have a percolation rate averaging 3 MPI. <br /> Alf rieighboring wells are located greater than 100'away from proposed treatment area. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. T'he power s�pply ar.d switches <br /> must be located ou[side the manhole and pumping chamber in a weatherproof encloswe. A waming device must be <br /> installed with light and sound devices;this is in case of a pump failure. <br /> The manifold and supply line must have back drainage to the pumping chamber. The distribution pipes shall have their <br /> ends capped. Be sure the rock and sand fill materials are clean. The sod layer below the entire mounded area must be <br /> tumed over,just break up the sod and be sure not to over work. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction. The area <br /> around both sites must be fenced off by the contractor before any construction begins.This Design is not valid <br /> and the System will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment <br /> accurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic eftluent efiectively. <br /> Nothing other tha��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 harmful damage to <br /> your septic system It is recommended that you pump the tank every year for 1 tank every two years for tH�o tanks. <br /> Sinc;c;rely, , . �i/[' d��N�} <br /> ' __.....____.. �� <br /> . �-------" A�'► <br /> �;� <br /> �, <br /> ; i t► 7'$ �- " �o ��RMIT1�. <br /> Joseph J.Olson '��T�� � <br /> , � �aw�swrrg cox�ec�o��r�, <br /> `/ ` tarr�av�oo�Ract��w�r <br /> � 4he�s oo.aeia��r.tar y.i.WM+.in�JlttairlR� <br /> � ��1� �►�u a�+�...r.��r�+.�a..�.�.�an,�. <br /> ��A�►����� +�►�x�r��ar�i►'�a«��'«+�r� <br />
