Upslope 30' of TH#1, 8" to 12" of Fill soil was found with the original soil not being <br />compacted. In this area, the Fill soil will need to be removed with a backhoe prior to <br />installing the new system. <br />Recommend to install a minimum 8" diameter solid PVC pipe from the culvert at the <br />driveway & outlet downslope of the tanks to allow small flows from rain runoff from <br />saturating the soil at the toe of the mound. <br />The soils at a depth of 12" have a percolation rate averaging 10.4 mpi. <br />A pumping chamber will need to be installed to lift the effluent to the treatment area. <br />The power supply and switches must be located outside the manhole and pumping <br />chamber in a weather proof enclosure. A warning device must be installed with a light <br />and sound device, this is in case of a pump failure. <br />The manifold and supply line pipe must have back drainage to the pumping chamber. <br />The distribution pipes shall have their ends capped. Be sure the rock and sand fill <br />material are clean. The sod layer below the enti-e mounded area must be turned over, <br />just break up the sod, be st ire not to over work. <br />All neighboring wells are located greater than 100' away from the proposed treatment <br />area. <br />Keep all heavy equipment off of the proposed treatment area before and after <br />construction. The treatment area should be marked off before construction. This <br />Design is not valid & the system will need to be relocated if failure to protect the areas <br />proposed for On -Site Sewage Treatment occurs. <br />With proper installation and maintenance, this system should have no problem in <br />treating septic effluent effectively. <br />2 <br />
