June 16 2000 <br /> Re: Soil Boreings, Percolation Tests, System Design. <br /> We were retained by Brian Kerber to provide criteria for the on-site sewage system for the <br /> property located at 740 Orchard Park Rd. In the City of Orono <br /> There were a total of 6 soil borings and 4 percolation tests done on this site and it appears that <br /> there is room for a new primary and alternate sites for septic systems on this property. <br /> This is based on a three bedroom, type one, single family home with maximum flow of 450 <br /> gallons per day. This house exists on this lot at this time. <br /> From these tests it was determined that a high water table exists at a depth of 16 to 24 inches <br /> below the ground surface. The high water table determines that only a mound type drainfield <br /> may be installed, to meet with code. <br /> Percolation tests range from 6 to 12 minutes per inch on the two sites tested. <br /> All neighboring wells are located greater than 100 feet from the proposed drianfield site. <br /> See attached sketch for locations. <br /> These areas must be protected from any traffic to be used for any future septic sites. If they are <br /> not protected the data collected herein will become Void and new testing shall have to take <br /> place. <br /> This design is in compliance with local codes and Minnesota Pollution Control Chapter 7080 as <br /> of the date listed above. <br /> Respectfully <br /> J <br /> Bob Volkenant <br /> MPCA License#56 <br />
