~ Mark Johnson 4455 Bayside Rd. Parcel B Orono, Henn. Co., MN S-P TESTING, INC. 951 KATYDID LANE ST. MICHAEL, MN 5537 497-3566 Steven B. Schir May 19, 1990 This system is Designed for a Type 1, four bedroom ho~e and in accordance with the Minn~sota Pollution Control Agency Chapter 7080-and local ordinances. The soils on this site are typical of SCS soils mapped -KkB -Kilkenny loam. A seasonally high water table was located at 12", 14", 16", 18", & 20", (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 17.3 min/inch and are adequate for treating septic effluent. A pumping chamber will need to be installed to lift 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 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. ~he 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. (Mercury floats are a good method). All neighboring wells are-located more than 100' away from the proposed treatment area. Keep all heavy equipment off of~he proposed treatment area before and after construction as much as possible. The treatment area should be marked off before construction • ------- • Soil and Percolation Te,t, Septic Sy,tem De,ign CONT'D --------·------·--"'-'"·-···"··"·•·· _______________ ..,,. ____ _ '"'"'"''''''~,,-,.~...,~,~,~ f ""A ,_,._,,..,.,,..,,,_,.._,_~
