Ted For$ and Associates 107 West Sixth Avenue, Suite 205 · Anchorage, Alaska 99501 · (907) 274-9517 Sept:ember 19, 1978 Mrs. Barbara Erskine 3636 Lore Road Anchorage, Alaska Subject= Septic Tank Inspection for Lot 2, Didrickson Subdivision Dear Mrs. Erskine; On September 15, 1978, we performed an adequacy test on the septic system which serves the subject property as you requested. The adequacy test was ~erformed as follows: Initial wastewater depth in the seepage pit - 3;55' The seepage pit was filled full by adding 200 gallons of water to the wastewater already in the pit. The seepage pit was then pumped out completely. This was accomplished by pumping 1,300 gallons from the pit. 1000 gallons of water was then pumped back into the seepage pit, the depth measured 3.30 feet. The septic tank was then pumped clean after which the depth in the seepage pit measured 3.25 feet. The depth in the seepage pit was then measured every 10 minutes over a 40 m~nute period. The depth remained at 3.25 feet. After a period of 7.5 hours, the depth in the seepage pit had dropped to 2.90 feet. After a period of 66.5 hours, the depth in the seepage pit was 2.28 feet. During this period, no'wastewater was admitted into the seepage pit since the empty 1000 gallon septic ta~k was being filled. From this data, it was determined that the seepage pit percolatlon rate is 4.62 gallons per hour. Since'the septic tank had not been pumped for several years, wastewater was apparently short circuited directly from the house to the seepage pit. This caused clogging of the voids in the bottom 3% feet of the seepage pit. Over 95% of the percolation in the seepage pit is therefore, taking place above the Engineerin9 · Planning Barbara Ersklne Page 2 Septic Tank Inspection for'L~t2, D~drickson Subdivision 3% foot level. Since the seepage pit capacity above this level is only about 300 gallons, the capacity of the system is only 300 gallons with a total effective absorbtion area of less than 100 square feet. This septic'system, in its present state, is not adequate to reliably serve the existing house. We, therefore, recommend that the seepage pit be chlorinated and collapsed, and a new seepage pit or drainfield installed to the south of the existing seepage pit. Before this can be done, a new permit must be obtained from the Anchorage Health and Environmental Protection Department. This permit costs $20.00 and will show the minimum dimensions and design criteria for construction of a new drain field. We recommend a new trench type drain field or seepage pit with a minimum absorption area of 600 square feet. This is based on a soil rating of 150 square feet per bedroom and a four bed- room house. If ybu have any questions, or if we can be of further service to you, please feel free to contact us. Sincerely, TED FORSI AND ASSOCIATES Tom W.
