No- 229 'ORONO, MINNESOTA 10-5-85 F-.Q6� �t1 On August 29-31, 1985 two proposed lots were tested for both primary and alter- nate drainfield sites to determine their suitability for on -site drainfield sys- tems. Testing was done in accordance with Individual On -Site Sewage Treatment Cve+nee C+m..d...d.. /uer •n % 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 moderately high seasonal water table, shallow trench systems would be needed for both sites. 0000 Lot 2, the south lot, had an average peroolation rate of 21.6 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. Additional information follows. If any other information is needed, please contact me. Sincerely, PERCOR, INC.
