Schirmers <br /> April 30 , 1991 <br /> Jim Schumacher <br /> 640 Old Long Lake Rd. <br /> Orono, Henn. Co. , MN <br /> This On-Site Sewage Treatment System is Designed for a Type 1, six <br /> bedroom home in accordance with the Minnesota Pollution Control <br /> Agency Chapter 7080 and local ordinances . __ <br /> The soils on this site are typical of SCS _soils mapped - BuB - <br /> Burnsville sandy loam. A seasonally high water table was not <br /> present. The Soil Borings indicate traces of rust color. 2 <br /> Soil Borings were completed 132" & 138" deep. The soil profile is <br /> a medium sand to the bottom of these borings . The rust colors are <br /> layered with no gray colors . It is my opinion this is not mottled <br /> soil . A Standard Trench System may be installed. <br /> The soils at a depth of 30" have a percolation rate averaging 4 . 4 <br /> min/inch. <br /> Each trench will need to be over excavated a minimum of 12" and be <br /> replaced with uncompacted loamy sand. This liner is needed to slow the <br /> effluent down for treatment. If drop boxes are used with a minimum of <br /> 4 trenches , this liner is not needed. <br /> All neighboring wells are located greater than 100 ' away from the <br /> proposed treatment area . <br /> This site has an existing failing system due to being too small , <br /> plugged with solids & tree roots . The existing tanks are block <br /> type & must be abandoned, pumped & filled with soil . <br /> CONT ' D <br /> Soil and Percolution Teata <br /> Septic System Deaign <br />
