WNW, MN 55378 • (612) 497.36M July 22, 1992 Donnie wells 4485 Bayside Rd. Orono, Venn. Co., MN This On -Site Sewage Treatment System is Desiynad for a Type 1, Lhrue bedroom home in accordance with the Minnesota Pollution Control AyenCy Chapter 7000 and local ordinances. The soils on this site are SCS soils mapped - KkA - Kilkenny loam. A seasonally high water tables wma located at 20" to OS". (mottled soil). Due to the seasonally high Water table, a Pressurized Mound System will need to be installed. The bottom of the rock bed must be located at least 3' above the seasonally high water table. The soils At a depth of 12" have a percolation rate averaging 3.1 min/inch. This site has an existing failing system with surface discharge. The existing tank is old & will need tv be abandoned, pumpod L filled with moil.( Less than 50' from well). A lift pump will be needed in the luwwA. level. A bumping chamber will need to be installed to litt the effluent to the treatment area. The manifold and supply line pipe must have back drainage to the pumping chamber. The distribution pipes shall have thwIL 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. A new supply line Will exit tits houae at the southwest corner. The power supply and switches must be located outside Lhe nialthOlet and pumping chamber in a weather proof enclosure. A warleing device must be instilled with a light anti sound device, this is in cane of a pump failure. Mercury floats are a good method. All neighboring wnllm Are located greater than 151 away from the proposed treatment area. CONT'D 4V (2) Bonnie Wells 4465 Bayside Rd. Orono Keep all heavy equipment off of the proposed treatment area before and after construction. The trentmant nrwn ahould ho mnrkeri off hafnra construction. This Design is not valid & the System will need to be relocated if failure to protect the areas proposed for On -Site Sewage Trantmant nr-riira . With proper installation and maintenance, this system should have no problem in treating v*ptic effluent effectively. Nothing other than gray water, (laundry, showers, etc.) human waste i toilet tissue should be diopooed of into the veptio tanko. Garbage disposals are not recommended. Additives must nqt be used, they may cause harmful damage to your septic system. Recommend to pump your tank every yeeir if you have 1 tank i every 2 years if there are 2 tanks. Steven D.
