I suspect that the trench is coming off of the old crib, making most of our area in the original design not useable. The 25'on the northeast is already do.1, and I propose to corne back about 5 ft from the old trench, and make an L, to the south for about 14 ft. I took 2 ft off in the calculations due to the L We can get anothe� trench to the south about 45 ft long, and I'll think we'll have about 3.5 ft effective. losing some because the OG is higher In the south.

Box 196650 Anchorage, AK 995IM650 RE: McMahon Bik 1, Lot 16 Septic System Upgrade To Whom It May Concern: Attached please find the application and supporting documentation for upgrading the septic system for the referenced 4 bedroom house. The existing septic system was installed in 1967 and was not documented. The septic tank is located 70 ft from the well, and it appears that the crib has caved in. It is proposed to abandon the old tank and crib and install a new 1250 gallon steel tank and deep trench drainfield. The proposed design is based upon a test hole dug on June 20, 2005. The hole was dug to 21.0 ft with no water encountered. After a 7 day monitoring period. no water was detected. The proposed drainfield will be installed in two sand layers between 8 ft and 15 ft. A layer of silt occurs between the two sand layers from 9.5 ft to 11.3 ft. Sewer rock will be installed across the silt interval, but no credit is given for effective depth. A percolation test conducted between 7.5 ft and 8.0 ft resulted in a rate of 1 minute per inch. An application rate of 1.2 gpd/111 is used in the design. The soil log is attached. Proposed Soil Absorption System: 4 Bedrooms x 150 GPD/BR 600 GPD System Type: Deep trench Application rate: 1.2 gpd/ ft' 600 GPD / 1.2 gpd/ft' 500 ft' required Maximum Depth: 15ft Effective Depth: 5.0 ft Proposed Length: 50ft Absorption Area: 500 ft2 Sewer Upgrade Permit Application forMcMahonBlk I Lot 16 Watkins Engineering, Inc.; June 27,2005, page 2 There are no surface waters or private wells within 100 ft of the proposed septic system. The slope is towards the northwest at 9%, and the drainfield will be installed parallel to the contours. I am not aware of any adverse effect that this upgrade would have on any adjacent properties' water and wastewater treatment needs. Thank you for consideration of this permit application.
