If this turns out to be the case, <br />the preferred method would be to pump the basement only and <br />gravity flow the upper floors. Presuming a basement pump is <br />needed, the original system should be kept as far uphill as <br />possible to preserve the lower area for future use. <br />The well must to located at least 75' from either drainfield <br />site, hence the acceptable well locations fall in a small area <br />at the nortwest corner of the lot. Any water line under the <br />driveway should be placed a minimum of 7' dce with 2" of styro- <br />foam insulation to eliminate potential freezing problems. <br />~KEEP ALL TRAFFIC, FILL, GRADING, ETC.
