The system consists of 2-1000 gallon septic tanks & a <br /> trench system. The bottom of the 1 st & 3rd trenches was found at 36" &42" below <br /> grade. Soil borings#1A & ZA found mottled soil (redox features) at 30" &40" below <br /> grade. This system has no separation from the bottom of the trenches & redox features <br /> & is classified as non-compliant. <br /> This on-site sewage treatment system is designed for a Type 1, 4 bedroom home, in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances. <br /> Th,e soils,on this site are a sandy loam to clay loam. The periodically saturated soils <br /> 24 to 38 were located at (redox features). Due to the seasonally saturated soils, a <br /> Pressurized Mound System will need to be installed to treat septic effluent. The bottom <br /> of the rock must be located at least 3' above,the saturated soils. pR0 <br /> ���4�Y <br /> The soils at a depth of 12" have a percolation rate of 4.8 mpi. <br /> The existing tanks may be used if water tight. If not water tight, abandon, pump &fill <br /> with soil & install new tanks to meet Orono Ordinance. <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 /> OR 1 ���� <br /> ONO COPY ������M� <br /> � <br />
