This equates to an application rate of 5 to 6 GPD/SF in accordance with Municipal Code. The absorption sytem on the lot was originally designed to a much more conservative rate of 2 GPD/SF. The peat layer found during construction was less than anticipated in the design and resulted in an effective absorption area of 180 SF. Using the code mandated application rate of 5 GPD/SF the effective absorption area more than satisfies the design requirement of 450 GPD. We are confident the absorption system as constructed on this lot exceeds the design requirements of the Municipal Code. Sincerely, Michael E. Anderson, P.E.

We are therefore requesting a permit be issued to allow the construction of a new well and septic system to serve the home. A permit was previously issued on June 28, 2017, but it has since expired. The conditions in the area have not changed since the issuance of that permit. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system. No existing wells are less than 100’ from the proposed septic system and the proposed well is more than 50’. In addition, the proposed well to serve the lot does not conflict with septic systems in the area. The surface drainage on the lot is to the northwest as shown by the surface contour lines on the plan. The drainage pattern will not be changed as a result of this project. The new absorption bed will be constructed with Engineered Receiving Soils (E.R.S.) in accordance with the Municipal Code along with an Advantex Treatment System with an AX-20 Filter Pod and an ultraviolet treatment tube. Horizontal conveyance will be utilized to transport the effluent through the organic material surrounding the absorption bed and away from the area. The distribution line in the bed will be placed at 2.5’ above the existing ground to provide 6.5’ of clearance from the in situ silt below which has been found to be inconsistently permeable throughout the area. Sections of subsurface soils in the area have been determined through percolation testing to absorb water at rates faster than 120 minutes per inch, but these sections are inconsistent and the majority of the subsurface soils are thought to be impermeable. A minimum of 2’ of MOA approved coarse sand will be placed below the bed and 4’ of clean well graded gravel (GW) meeting the requirements of Municipality of Anchorage Standard Specifications for Type II or Type IIA select backfill will be placed under the sand and to a depth of 4’ below the surface or to the silty in situ layer. The test holes placed on the lot in the past and monitored for many months indicated no groundwater developed on this lot. The engineered fill will be placed in 12” lifts and compacted to create a stable base for the absorption bed. The fill slopes will be constructed at a 2:1 angle of repose with a 4” topsoil cover. All disturbed or new surfaces shall Municipality of Anchorage On-site Water and Wastewater REVIEWED FOR CODE COMPLIANCE OSP191288, Rebecca Carroll, 07/18/19 then be seeded to produce vegetation and prevent erosion. We are proposing to construct a new 450 square foot by .5’ effective depth absorption bed to treat and dispose of the effluent generated in the house. The additional porous material beneath the bed will provide surge volume and septic treatment and increase the surface area for water absorption to the surrounding strata. Water will flow horizontally through the 90’ LF perimeter of the bed by 1’ effective depth sidewalls or a total effective area of 90 SF. A percolation rate of 4-5 minutes per inch has been utilized for the peat with a conservative application rate of 2 GPD/SF. The ground surface on the lot in the area of the absorption bed slopes to the northwest. The new bed will be constructed parallel with the contours of the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100’ from all wells and any surface water and 10’ from the proposed and existing water services in the area. If the system is constructed in accordance with our design it will not conflict with adjacent wells and septic systems. Sincerely, Michael E. Anderson, P.E.
