� � � � <br /> � <br /> � <br /> • Drainfield— Use Infiitrator H-I 0 High Capacity Sidewinder brand chambers for the drainfield <br /> � media. This model of chamber is equal to I 2" of side-wall when comparing to a standard rock <br /> trench configuration. Dig two -44' x 3' wide trenches to the lengths indicted in drawing <br /> � detail. Place a drop box at the end of each trench, connecting drop boxes with 4" pvc pipe. <br /> Dig the trenches to the elevations given in attached design detail section. Place twelve inches <br /> of a sandy to loamy soil material over each of the chambers. Establish a vegetative cover over <br /> � the entire drainfield area. <br /> � • Insulation - <br /> ✓ Insulate the septic tank and lift tank by placing 2" of polystyrene insulation on to of the <br /> � tanks. <br /> ✓ Insulated entire sewer pipe frcM house to septic tank and th� ��NN�r �� �m the lift tank <br /> � to the drain fieid by placing 2" of polystyrene over the supply line, extending a minirnum <br /> of I' foot on each side of the pipe. <br /> ✓ Specifications for insulating the sewer pipe between the septic tank and lift tank as it <br /> � passes below the road easement will be detailed by others. <br /> I 7. Limitations - Our investigation, layout, design, and recommendations are based on data submitted. <br /> � If conditions considerably different from those described in this report are encountered, we must be <br /> � notified. If proposed construction is changed, we must be notified to evaluate the effect of the <br /> changes on the wastewater system. Any chan�es to the desi�n must be approved by the designer ��� <br /> wil� be assessed additional design costs. Specific items called for in the materials list must be used <br /> Iunless a change has been approved by the desi�ner. If changes are made to the design without the <br /> knowledge and approval of the designer the design shall be void. All construction is to be in <br /> I accordance with the ISTS regulations. Pipe type and size, installation requirements, septic tank <br /> construction, and other specifications not depicted in our report are to conform to ISTS regulations. <br /> The installer of the system is to be licensed by the Minnesota Pollution Control �gency. <br /> , �i,�.��� � <br /> Kevin J.
