Box 196650 Anchorage, Alaska 99519-6650 Ref: Proposed Septic System for Ilidden Hills Subdivision, Lot 39, Block 1, To whom it may concern: The proposed 4 bedroom house is to be served by the existing private well and a proposed septic system. One test hole was excavated on the property. The drainfield will be designed around the 30 foot radius of this test hole. Because of the limited space constraints we are proposing that a new 1500 gallon Advantex system, and a deep trench type drainfield be installed. In order to do this, a waiver will be required from the existing well to the proposed Advantex tank and drainfield. Comments regarding the design are summarized as follows: 1. SOILS: See the attached log, which shows the soil classifications, groundwater monitoring, and the percolation test results. 2. TRENCH DESIGN: a. Percolation Rate: <1 minutes/inch b. Allowable Application Rate: 6.0 gallons/da�/R2 c. Proposed application rate: 3.0 gallons/day/ft d. Number of Bedrooms: 4 e. Design Flow: 600 gallons per day f. Minimum Absorption Area: 200 f12 g. Total Depth: 10 feet (maximum.) h. Effective Depth: 6 feet L Width: 2.5 feet j. Proposed Length: 20 feet long k. Effective absorption area = 240 fl? 3. SURFACE WATERS: There are no surface waters within 100+ feet of the proposed septic system. 3701 E. Tudor Road, Suite 101 r Anchorage, AK 99507 Ph: (907) 337-6179' Fax: (907) 338-3246 • Websitc: gamessengincering.eom 4. TOPOGRAPHY: As can be seen on the attached topography site plan, the average topography in the area of the proposed drainfield is approximately 20-25% running north to south. In short, there are no slope concerns. 5. WELL WAIVER: We request a 75 foot waiver from the existing well to the proposed septic system. The following are some mitigating factors for the justification of the requested waiver: • There is a slight mound and heavy vegetation between the well on the adjacent property and the proposed septic system. If the septic system was to overflow, it appears that the effluent would not travel toward the wellhead. • The Advantex tank is made of fiberglass and will not corrode and leak untreated effluent into the ground. • The Advantex treatment system is to be installed with a "Vericomm" system that alerts the service provider, Anchorage Tank and Welding, Inc., of an alarm condition, so that problems can be corrected immediately. • The effluent that comes from the Advantex tank is treated to M.O.A. secondary standards. As can be seen on the attached well logs, the aquifer is relatively deep, with approximately 175- 200 feet of fine silt, sand, and clay with some gravely soils that have served to inhibit the migration of untreated wastewater into the aquifer. Recent water sample results indicated nitrate levels to be 0.10 mg/L and no bacteria were present. Based upon the aforementioned facts, it appears that there is minimal risk in granting the requested waiver/s. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact us at 337-6179. Thank you for your assistance. A Sincerely, P.E., M.S. NOTE: Attached is a site plan dran,ing, a design drawing, a topography site plan, a soils log, and a 7 page construction specification letter which are all part of the design package for this septic system. 3701 E.
