No. 229 L--��_._____` ORONO, MINNESOTA CITY (,1h �� ,7 J 10-5-85 On August 29-31, 1985 two proposed lots were tested fnr both primary and alter- nate drainfield sites to determine their suitability Tor on -site arainfield sys- tems. Testing was done in accordance with Individual On -Site Sewage Treatment System Standards(WPC-40). Lot 1, the north lot, had an average percolation rate of 7.7 minutes per inch for the primary site(holes 1-4) and a rate of 10.4 minutes per inch for the alternate site(holes 5-6). With the possibility of a ,,w:.,i itely high seasonal water table- challnw tranrh cystemS would by np d§j 4n r �♦ �{+e Lot 2, the south lot, had an average percolation rate of 2 .6 minutes per inch on the primary site(holes 1-4) and 15.2 minutes per inch for the alternate site(holes 5-6). Because of the high seasonal water table, shallow trench systems would be needed for both sites with some fill required over the trench- es or an interceptor draintile__used to lower the water table. rmation follows.
