Blk 1 Orchard Farms <br /> Orono. Hennepin County <br /> This on-site Sewage Treatment System is designed for a Type !four-bedroom home in <br /> accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances. <br /> The periodically saturated soils were located at 16-20 inches(mottled soil). Due to the <br /> periodically saturated soils,a pressurized mound system with 6 inches of rock will need to be <br /> installed to treat the septic effluent. The bottom of the treatment area must be located at least 3' <br /> above the saturated soils. This system is designed with 6 inches of rock. <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 7 MPI. <br /> A variance may be needed for the septic tanks to be deeper than four feet below grade. A Darwin <br /> 2250 gallon septic tank must be used. <br /> The supply line must be insulated under the driveway or laid as a directional bore force main <br /> below frost. <br /> Clean outs must be installed on the end of the laterals for maintenance. <br /> A 1000 gallon Darwin pumping chamber will need to be installed to lift the effluent to the <br /> treatment area. The power supply and switches must be located outside the manhole and pumping <br /> chamber in a weatherproof enclosure. A warning device must be installed with light and sound <br /> devices: this is in case of a pump failure. <br /> Nothing other than gray water.(laundry,showers,etc.)Human water and toilet tissue <br /> should be disposed of into the septic tanks. Garbage disposals are not recommended. <br /> Additives must not be used; they may cause harmful damage to your septic system.It is <br /> recommended that you pump the tanks even'two years. <br /> • <br /> Sincerely. <br /> CTTY OF ORONO <br /> SEPTIC PE; IT PL�:,y''R VIEW <br /> Joseph J.
