The approved separation distance is 94.0 feet. This waiver approval applies to the existing septic tank only.

However, once the stamped survey was completed, we found out that the GPS was not as accurate as expected and that the edge of the tank is approximately 94' from the center of the well. The septic tank is on the other side of the home from the well. Grade slopes down from the house toward the septic system to the northeast. There is no possibility of effluent running out of the tank and contaminating the well head. Any overflow of effluent would flow away from the well toward the septic trenches. The design of the trenches, with 2' of filter sand, adds additional treatment before the effluent flows downward into the actual receiving soils. Also, although there is no well log available, the previous test hole information shows sands and silts below 10-16', which will also provide significant additional treatment before any possibility of reaching the well underground. All of this additional treatment would offset the 6' less separation. In our judgment, there is no threat of contamination of the well head due to the slightly closer location of the septic tank. For this reason, we request a waiver be issued for the 94' separation to the well.

The attached site plan identifies the location of the home as well as the existing well, septic location. The owner currently has a 4-bedroom system, but has asked for a 5- bedroom replacement. The ground surface on the lot slopes toward the road moderately around the home, but where the test holes were dug the ground flattens out to 1-5% slopes. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown. The new system will be a minimum of 100’ from all wells and surface water, and more than 5’ away from the septic tank. Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

This investigation was performed in accordance with your request of May 6, 1974, and those procedures outlined in a letter dated September 13, 197i by Mr. Roll Strickland of the Greater Anchorage Area Borough Department of Environmental Quality. A single test hole was put down within the Tract B-1 area for the purpose of defining genera], subsurface soil conditions for the proposed .sanitary system. Excavation was accomplished with a tractor-mounted backhoe and the testhole was extended to a total depth of 16.0 feet below ground surface. The final log.prepared for the test hole has been included in Drawing A-01. Ground water was not encountered in the test hole. We appreciate being given this opportunity to be of service to you.
