Due to seasonally saturated soils and the <br /> existing system an 01111,R pressurized Mound System will need to be installed to treat septic effluent. The bottom of <br /> the treatment area must be located at least 3'above the saturated soils. <br /> Chapter 7080.0178 Subp.3.Compliance.Systems designed and constructed under this part shall be considered in <br /> compliance if they meet the conditions of the approved monitoring plan.The monitoring plan is to be set by the LUG. <br /> The L.U.G.monitoring plan is two times a year for two years.If there are no problems found the monitoring may stop. <br /> The soils at a depth of 12"have a percolation rate averaging 4 MPI. <br /> All neighboring wells are located greater than 100'away from proposed treatment area. <br /> The absorption area of the proposed system is greater than 75 feet from the existing creek. <br /> The existing tanks may be used upon approval of the local inspector.If the tank is not usable two new 1000 gallon <br /> tanks must be installed. <br /> A new 1000 gallon lift station must be installed. <br /> A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches <br /> must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be <br /> installed with light and sound devices;this is in case of a pump failure.The manifold and supply line must have back <br /> drainage to the pumping chamber. <br /> Keen all heavy equipment off of the proposed treatment areas before during and after construction. <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. <br /> Nothing other than gray water,(laundry,showers,etc.) Human water and toilet tissue should be disposed of into the <br /> septic tanks. Garbage disposals are not recommended. Additives must not be used;they may cause harmful damage to <br /> your septic system. It is recommended that you pump the tank every year for 1 tank every two years for two tanks. <br /> Sincerely. <br /> Joseph J.Olson <br />
