Orono,Hennepin County This on-site sewage treatment system is designed for a type 1 four bedroom home in accordance with the Minnesota Pollution Control Agency Chapter 7080 Other standards. Due to compacted soils.The soil must be dug out 30 inches under the proposed system and replaced with clean sand.This site is closer than 50 feet from the wetland.A city variance may be needed to install the system.I contacted Willie Gibbs from the city to discuss the lot.It was our conclusion to use the best possible site for the system.The primary site shown for this lot has the least amount of compaction. Therefore it is this designer's opinion that this is the best site.The dig out under the system must be the absorption area.The absorption area for a four bedroom house is 50 X 20 feet.The depth of soil to be removed is 30 inches deep.The amount of sand to replace the soil dug out is 101 cubic yards The soils on this site are compacted.The compaction ranges from 0-52 inches below grade All neighboring wells are located greater than 100 feet from proposed treatment area. A LUG.Variance maybe needed to install the other system and to be closer than 50 feet from the wetland. The wetland is a canary grass wetland not a cattail wetland. The homeowner will be responsible for periodic monitoring of the other septic system. The monitoring set by LUG. The mitigation plan for this property is pressurized other mound system also the compacted soils dug out. A tank filter and cleanouts on the laterals will need to be installed. ORONO COPY A water meter will need to be installed in the house. A pumping chamber will need to be installed to lift the effluent to the treatment area. The power supply and switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A warning device must be installed with light and sound devices;this is in case of a pump failure.Keep all heavy equipment off of the proposed treatment areas before and after construction. Nothing other than gray water,(laundry,showers,etc.)human water and toilet tissue would be disposed of into the septic tanks. Since ely ORONO COPY CTry OF OR•NO SEPTIC P T P' '+ '1.

Calculate Absorption Width:Media Width (2.B)X Mound Absorption Ratio (1.D)=Absorption Width 10.0 ft X 2.0 = 20.0 ft B. For slopes from 0 to 1%, the Absorption Width is measured from the media equally in both directions. Calculate Absorption Width Beyond the Media:Absorption Width -Media Width +2= Width beyond Media ( ft - ft) + = ft C. For slopes>1%, the Absorption Width is measured downhill from the upslope edge of the Media. Calculate Downslope Absorption Width: Absorption Width (3.A) -Media Width (2.B)=ft 20.0 ft - 10.0 ft = 10.0 ft 4. MOUND SIZING A.
