NE, Hanover, MN 55341 <br /> (763) 498-8779 fax (763) 498-8290 <br /> NEW FUTURE SITE FOR THE EXISTING HOUSE. <br /> Revised April 2,2019 <br /> Hollis Property <br /> Proposed Lot 2 <br /> Orono,Hennepin County <br /> This on-site Sewage Treatment System is designed for a future Type 1 five-bedroom home in accordance <br /> with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br /> Keep all heavy equipment off the existine and new future septic sites. <br /> The seasonally saturated soils were located at 12-22 Inches(mottled soil).Due to the seasonally saturated <br /> soils,a pressurized mound system will need to be installed to treat the septic effluent.The bottom of the <br /> treatment area must be located at least 3'above the saturated soils. <br /> All neighboring wells are greater than 100'from proposed treatment areas. <br /> The soils at a depth of 12"have a percolation rate averaging 13 MPI. <br /> If the future site is ever used the septic tanks will need to be certified before they could be used. <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent <br /> effectively.Nothing other than gray water,(laundry, showers,etc.)Human water and toilet tissue should be <br /> disposed of into the septic tanks. Iron filters cannot eo into the septic system.Garbage disposals are not <br /> recommended.Additives must not be used they may cause harmful damage to your septic system.It is <br /> recommended that you pump the septic tanks every two years. <br /> Sincerely, <br /> Joseph J.Olson <br />
