� . � <br /> TO: Greg Gappa, Public Services Director <br /> FROM: Stephen Weckman, On-Site Systems Manager <br /> DATE: August 18, 1998 <br /> RE: Request for exclusion from municipal sewer project,Jorgen Viltift-1155 Heritage Lane <br /> As per your request, the City performed a review of your septic system to determine whether you are <br /> eligible to be exempted from connecting to the Municipal Sewer at this time. In order to be exempted <br /> from connection at this time, we needed to show that the septic system meets a three foot separation <br /> to the seasonal water table, the septic tanks have bottoms, and the system is of adequate size for the <br /> dwelling. <br /> Several soil borings were performed in vicinity of the drainfield to determine the depth to the seasonal <br /> water table. Due to gravelly soils and the fill soils near the drainfield, only two borings reached a <br /> depth of seven feet (three feet below the drainfield). One boring was located in fill soils and was not <br /> used to identify the depth to the seasonal water table. The remaining soil boring showed no evidence <br /> of a seasonal water table. <br /> Inspection of the septic system revealed that the system is of adequate size and the tanks are of <br /> suitable construction to remain in use. The tanks have bottoms and are therefore not considered to <br /> be cesspools. The septic system inventory information indicates that 600 square feet of drainfield area <br /> was installed in 1969. Also, a typical 1969 septic system installation would have twelve inches of <br /> rock under the distribution pipe. A five bedroom dwelling would then require 500 square feet of <br /> drainfield area to be of adequate size in the sandy soils. <br /> Based on this site inspection, your residence does meet the conditions necessary for exclusion from <br /> municipal sewer connection at this time. The septic system may or may not meet all current codes, <br /> but is compliant and of adequate size for its current usage. If the system becomes non-compliant due <br /> to surface discharge or future changes in the septic system regulations, the residence will be required <br /> to make connection to municipal sewer. Any changes in the size or usage of the residence that would <br /> require addition or alteration of the septic system must instead be connected to municipal sewer. <br />
