Schirmers <br /> Nov.:c.ber 28 , 1988 <br /> Jane Bonner • <br /> 970 Wayzata Blvd. <br /> Orono, Henn. Co. , MN <br /> • <br /> This system is Designed for a Type 1, Three bedroom home and in accordance <br /> with the Minnesota Pollution Control Agency Chapter 7080 and local <br /> ordinances . <br /> The soils on this site are typical of SCS soils mapped -• HbC - Hayden <br /> loam. A seasonally high water tabJ.e was located at 12" ,• 16" & 18" , <br /> - (mottling) . Due to the seasonally high water table, a pressurized mound <br /> system will need to be installed. The bottom of the rock bed must be <br /> located at least 3 ' above the seasonally high water table . <br /> This site has an existing failing system, tanks with over floN,7. The <br /> existing tanks are old and may not be possible to use . May be used <br /> upon approval by the local Inspector. <br /> The soils at a depth of 18" have a percolation rate averaging 17 . 5 min/inch <br /> and are adequate for treating septic effluent. <br /> A pumping chamber will need to be installed to lift the effluent to the <br /> treatment area . <br /> The manifold and supply line pipe must have back drainage to the pumping <br /> chamber . The distribution pipes shall have their ends capped. Be sure <br /> the rock and' sand fill , material are clean. The sod layer below the <br /> entire mounded area must be turned over, just break up the sod, be sure <br /> not to over work. <br /> The power supply and switches must be located outside the manhole and <br /> pumping chamber in a weather proof enclosure . A warning device must be <br /> installed with a light and sound device, this is in case of a pump failure. <br /> (Mercury floats are a good method) . <br /> All neighboring wells are located more than 100 ' away from the proposed <br /> treatment area . <br /> Keep all heavy equipment off of the proposed treatment area before and <br /> after construction as much as possible. The treatment area should be <br /> marked off before .construction. <br /> With proper installation and maintenance, this system should have no <br /> problem in treating septic effluent effectively. <br /> It is recommended to have Soil and Percolation Tests the septic tanks pumped <br /> every 2 years .
