This design is for an alternate site for this property. <br /> The soils on this site are a clay loam. The seasonally saturated soils were located at <br /> 14" to 18" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound <br /> System with 2 rock beds will need to be installed to treat septic effluent. The bottom of <br /> the rock must be located at least 3' above the saturated soils. The rockbeds are 17' <br /> apart which is the absorption width which classifies the system as standard. The <br /> distribution pipe will be the same level. <br /> Approval will be needed for the toe of the mound to be 15' from the right away. <br /> The soils at a depth of 12" have a percolation rate of 12.0 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 /> 1 <br />
