Co. , MN <br /> This On-Site Sewage Treatment System is Designed for a Type 1, four <br /> bedroom home Designed in accordance with the Minnesota Pollution <br /> Control Agency Chapter 7080 and local ordinances. <br /> The soils on this site are SCS soils mapped - HbB - Hayden loam. <br /> A seasonally high water table was located at 26" to 76" . The <br /> bottom of each trench must be located at least 3 ' above the <br /> seasonally highwater table. A Standard Trench System may be <br /> installed in the proposed Treatment area . A Pressurized Mound <br /> System will need to be installed in the future expansion area. <br /> The soils at a depth of 12" & 30" have a percolation rate averaging <br /> 5.9 min/inch. <br /> A lift pump will be needed in the lower level . <br /> All neighboring wells are located greater than 100 ' away from the <br /> proposed treatment area. <br /> Keep all heavy equipment off of the proposed treatment area before <br /> and after construction. The treatment area should be marked off <br /> before construction. This Design is not valid & the system will <br /> need to be relocated if failure to protect the areas proposed <br /> for On-Site Sewage Treatment occurs . <br /> With proper installation and maintenance, this system should have <br /> no problem in treating septic effluent effectively. <br /> CONT ' D <br />
