COP Orono, Henn. Co.,MN KEEP THIS PLAN SET ON SITE AT ALL TIMES The Revised design dated October 12, 2005 is being revised due to construction equipment traveling over the proposed treatment area which caused damage to the soil. This site has an existing on-site sewage treatment system which was classified as non- compliant by the City of Orono. 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 and local ordinances. The soils on this site are a loam. The periodically saturated soils were located at 26" to 40" (redox features). Due to the seasonally saturated soils, a Pressurized Mound System will need to be installed on a 12% slope to treat septic effluent. The bottom of the rock must be located at least 3' above the saturated soils. The soils at a depth of 12" have a percolation rate of 4.2 mpi. ORONO COPY The existing tank may be used if water tight. The soil 15' downslope of the mound must be protected. This area has been driven on & should be roughened up at the same time as the mound construction. The access road to the back of the property must be 20' downslope of the toe of the mound. By saving this area, allows movement of water downslope & allows space to add sand to the downslope toe of the mound if seepage would occur. ORONO COPY 1 , • 111111111111111111$111861 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 weather proof enclosure. A warning device must_be installed with a light and sound device, this is in case of a pump failure. The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have their ends capped. Be sure the rock and sand fill material are clean. The sod layer below the entire mounded area must be turned over, just break up the sod, be sure not to over work. If the tanks have less than 2' of cover, the lids, risers & maintenance hole covers must be insulated to a value of R10. Cleanouts for each later must be installed & be accessible from finish grade in an irrigation box with a ball valve. All neighboring wells are located greater than 100' away from the proposed treatment area. If a garbage disposal is used, an effluent screen will be needed in the 2nd tank. Keep all heavy equipment off of the proposed treatment area before and after construction. The treatment area should be marked off before construction. This Design is not valid & the system will need to be relocated if failure to protect the areas proposed for On-Site Sewage Treatment occurs. MANAGEMENT PLANS: The tanks need to be pumped every 2 years. Check with your pumper to set up a schedule. System inspected for wet areas by owner & or Inspector as determined by the local unit of government. Any other requirements as determined by the local unit of government 2 With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than human waste, toilet tissue, laundry, showers, water softener etc. should be disposed of into the septic tanks. Recommend Iron filters be diverted out of the system. Recommend to divert the water softner also if the iron filter is diverted. Garbage disposals are not recommended, due to adding more solids & fine solids passing through to the system. Excessive amounts of soaps, antibacterial soaps, cleaning agents, shower cleaners used every shower & chlorine agents may kill the bacteria needed to treat septic effluent. Additives are not recommended. Recommend laundering be limited to 3 to 4 loads per day. <6 - -./( ' Steven B.
