Co., MN <br />This site has an existing failing system which is surface discharging which is an <br />imminent health hazard and must be repaired or disconnected within 10 months. Soil <br />Borings completed in the area of the existing system found saturated soil (mottled soil) <br />less than 3' from the bottom of the system which also classifies this system as failed. A <br />new system will need to be installed. <br />This On -Site Sewage Treatment System is Designed for a Type 1, four bedroom home <br />in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br />ordinances. <br />The soils on this site are SCS soils mapped - HcC2 - Hayden Gay loam. The seasonally <br />saturated soils were located at 62" & 68" (mottled soil). The bottom of the treatment <br />area must be located at least 3' above the seasonally saturated soils. A Standard <br />Trench System may be installed north of the house. <br />The soils at a depth of 24" & 30" have a percolation rate averaging 18.2 mpi. <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 with <br />a light and sound device, this is in case of a pump failure. <br />All neighboring wells are located greater than 100' away from the proposed treatment <br />area. <br />
