This is an assumed design for a Type 1, four bedroom hpme for a pressurized mound system. We are assuming the worst conditions. In the spring the site will be evaluated the type of system will then be determined. This design is not valid without the completion of the soil borings and perco­ lation tests. Keep all heavy equipment off of the possible treatment areas as much as possible. Steven B.

STEVE SHIRMER8 April 21, 1987 G>/2, This system is designed for a Type 1, four bedroom home and in accordance with the Minnesota Pollution Control Agency standards WPC 40 and local ordinances. The sons on this site are typical of SCS soils mapped - KIC2 - Kilkenny loam boardered by LmB Lerdal loam. A seasonally high water table was loca­ ted at 14", 18", 20" & 26", (mottling). 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 18" have a percolation rate averaging 9.7 min/inch and are adequate for treating septic effluent. A pumping chamber will need to be installed to lift the effluent to the mound system. 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. The power supply and switches must be located outside the manhole and pump­ ing chamber in a weather proof enclosure. A warning device must be in­ stalled 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 before and after construction as much as possible. The treatment area should be marked off before construction. With proper installation and maintenance, this system should have no prob­ lem in treating septic effluent effectively. It is recommended that the septic tanks be pumped every 2 years.
