Olson—MPCA License#810 <br /> 11481 Riverview Rd NE,Hanover, MN 55341 <br /> (763)498-8779 Fax(763) 498-8290 <br /> December 10,2011 <br /> Tony Rochel ORCM CM <br /> 125 Tumham Road <br /> Orono,Hennepin County <br /> This septic tank System is designed for a Type 1,Five-bedroom home in accordance with the Minnesota Pollution <br /> Control Agency Chapter 7080 and local ordinances. <br /> The seasonally saturated soils were located at 18"-24"(mottled soil).Due to seasonally saturated soils,a pressurized <br /> Mound System will need to be installed to treat septic effluent The bottom of the treatment area must be located at <br /> least 3'above the saturated soils. <br /> The existing house is going to be removed.The existing septic tanks could not be found but must be abandoned. <br /> Due to limited space that is undisturbed.The future systems upslope dike must overlap the primary systems <br /> downslope dike.The absorption areas do not overlap.The future septic site must be fenced off when the primary <br /> site is being installed.When the septic system is built all materials must be placed from the southwest side of the <br /> system. <br /> The soils at a depth of 12"have a percolation rate averaging 8 MPI. ORONO COPY <br /> All neighboring wells are located greater than 100'away from proposed treatment area- <br /> All <br /> reaAll new tanks need to be insulated if less than two feet deep.Clean outs must be installed on the end of the laterals for <br /> maintenance. <br /> A 1250 gallon pumping chamber will need to be installed to lift the effluent to the treatment area The power supply <br /> and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure.A warning <br /> device must be installed with light and sound devices;this is in case of a pump failure. <br /> Keep all heavy equipment off of the proposed treatment areas before,during and after construction. The area around <br /> both sites must be fenced off by the contractor before any construction begins.This Design is not valid and the System <br /> will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. <br /> With proper installation and maintenance,this system should have no problem in treating septic effluent effectively. <br /> Nothing other than Bray water.(laundry,showers,etc.)Human water and toilet tissue should be disposed of into <br /> the septic tanks.Garbage disposals are not recommended.Additives must not be used:they may cause harmful <br /> damage to your septic system.It is recommended that you pump the tank every year for 1 tank,every two years <br /> for two tanks. <br /> Sincerely, <br /> C"OF ORONO <br /> SEPTIC PXMIT RE <br /> ORONO COPY MPEQTQR <br /> Joseph J.Olson DAT _r.
