Schirmers November 27, 1989 Woodhill Country Club 2 Acre Sub-Division Woodhill Ridge, Outlot B R:a • Orono, Henn. Co. , MN This system is Designed for a Type 1, four bedroom home and in accordance with the Minnesota Pollution Control Agency Chapter 7080 and local ordinances . The soils on this site are typical of SCS soils mapped - KkC - Kilkenny loam. A seasonally high water table was located at 60" , 66" , 74" , 78" & 90" , (mottled soil ) . The bottom of each trench must be located at least 3 ' above the seasonally high water table. A standard trench system can be installed. The soils at a depth of 24" & 30" in Percolation test holes #1 through #5 have a percolation rate averaging 24 .0 min/inch and are adequate for treating septic effluent. Percolation test hole #6 failed at 240 . 0 min/inch and the system can not be located in this area. 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. (Mercury floats are a good method) . The supply line pipe must have back drainage to the pumping chamber. All neighboring wells are located more than 100 ' away from the proposed treatment area. Keep all heavy equipment off of 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 problem in treating septic effluent effectively. Recommend to pump the septic tank every year if there is only 1 tank & every 2 years if there are 2 tanks . Soil and Percolation Tests Septic System Design Steven B.

Planning & Zoning Administrator DATE: March 13, 1990 Subject: #1503 Woodhill Country Club - Subdivision - Septic Testing I have reviewed the site of the proposed building lot and would make the following comments: 1. The testing for septic system drainfield sites provided by S-P Testing indicates the use of a trench drainfield system on 2 terrace levels at the north east corner of this steeply sloped lot. The tested sites provide the capability for as much as 950 lineal feet of drainfield, enough to provide for a primary system and nearly 2 alternate systems for a 5 bedroom home. 2. Since these sites are at the high end of the lot, one would expect some under ground drainage following the contours down the hill. With 80% of the lot having slopes greater than 18%, it would be critical to avoid placing the house directly downhill from the drainfield sites. Furthermore, it would be advisable to do no grade cuts within 50' downhill from any of the drainfield sites, and within 20' laterally at a level equal to the sites. Because these slopes near the drainfield are so steep, it would seem to be within the authority of the septic code to require these special conditions on site grading. 3. To that end, I have sketched on the S P Testing design, a "protected area" in which no structure and no grading or cuts should occur. Based on the preservation of this area and the stipulation that no cuts occur, I would recommend approval of the building site, finding that the provisions of the septic code for a buildable site are adequately met. , U�� C y t E 1 r1Q 4\1 '- r_t..• .1 -1 ox 0 z U v 10 • -- - . e W w --t Q ,os .or ,. 5 r-. — — — • ' Paoli • .N I y ' /I \ a'1' i ,•..1 1\.-0,1r,- 'ectr.7.7t), tr. \ 1 x 1 i s'il ' ''.:, 1;•-:'/ ./.34 '-- \ )10111&"14.1 =a crl< • _ , I I ' I.•' ' - —►e- 1 • a 41, 1 , .4.! ,,, , , 1-1. \ I . t 2g .E i >2 o- I I, .
