The system will need to be upgraded as determined by the City. <br /> This On-Site Sewage Treatment System is Designed for a Type 1, three bedroom <br /> home, in accordance with the Minnesota Pollution Control Agency Chapter 7080 and <br /> local ordinances. <br /> The soils on this site are a sandy loam. The seasonally saturated soils were located at <br /> 60" in soil pit#3 (mottled soil) . The bottom of the treatment area must be located at <br /> least 3' above the seasonally saturated soils. Iron stains were present in the pits in the <br /> coarse sand layer. These iron stains are not mottled soil. A standard trench system <br /> may be installed. <br /> The soils at a depth of 24 have a percolation rate of 5.4 mpi. <br /> The existing tank is old &will need to be abandoned, pumped &filled with soil. <br /> A pumping chamber will need to be installed to lift the septic effluent to the treatment <br /> area. The power supply and switches must be located outside the manhole and <br /> pumping chamber in a weather proof enclosure. A warning device must be installed <br /> with a light and sound device, this is in case of a pump failure. <br /> THIS SYSTEM lS DESI6NED FOR <br /> � BEDROOMS. ANY INCREASE IN NlJMBER <br /> � OF B�DROOMS INVALIUATES TNIS DESIGN. <br />
