OF HEALTH & ENVIRONMENTAL PROTECTION OCT lg80 RECEIVED I NO 02080 Hr. Harold U. Ottley 7744 Old Harbor Road Anchorage, AK 99504 Re: Adequacy Test for Existing Septic System on Lot 18, block 1, Creekside Subdivision No. 2. Dear Mr. Ottley: At your request our office conducted a percolation adequacy test on your existing septic system at the above-referenced iocation during the period September 29 and 30, 1980. You reported that your septic system consists of septic tank and seepage pit. The septic tank had not been pumped prior to the percolation test. Since the 2-bedroom house had been occupied up to the time of the test, a normai degree of saturation within the Ieach fieid is assumed. In accordance with the Anchorage Municipal Code, Chapter 15.65, Waste Water Disposai Reguiations, any on-site sewage disposaI system "shali have adequate capacity to properiy dispose of the maximum daiiy sewage fIow." The maximum daily fIow is computed at 75 gaiIons per capita-day (gcpd). Since "the popuiation of dweiiings shaii be estimated at two persons per sleeping room," the maximum daiiy sewage flow for your 2-bedroom house is 300 gaIIons per day (gpd). To test the soils absorption capacity as well as the surge capacity of your system, 117 percent of the maximum daily flow or 550 gallons of clear water was added in 50-gallon increments to the seepage pit. The water was obtained from your community water system'at its maximum sustained rate of about 5 gallons per minute (gpm). The liquid levels were monitored closely to detect any backup in the septic system. Mr. Harold U. Ottley ~October 2, 1980 Rage -2- The attached Table of Test Data represents the depths of Iiquid in the septic tank and seepage pit, and the quan- tities of water added. The septic tank was determined to be 12.1 feet deep (bottom of tank to ground surface) with an initiai depth of 4,7 feet in the tank. The seepage pit was measured to be 11.2 feet deep with an initial depth of 2.1 feet. Ground eievation at the septic tank standpipe is approximateiy ieveI with the seepage pit standpipe. The attached Summary of Test Results indicates that the liquid level in the seepage pit at the beginning of testing on Day 2 fell to 0 feet of its initial static level on Day 1, during a recovery period of 24 hours. On Day 3, the level had fallen to its static level on Day 2, during a recovery period off 25 hours. The levei in the seepage pit at its highest levei during the test (2.25 feet) was approximateiy 1.5 feet beiow the iiquid Ievei in the septic tank. Based on two days of testing, an average percolation rate for your existing septic system of approximateiy 350 gpd is indicated. Since an on-site sewage disposal system for a 2-bedroom dweiling must be capabie of disposing of 300 gaiions of sewage per day, your septic system appears to be functioning satisfactoriIy at this time. Many factors affect the operation of a soils absorption type of sewage disposai system. Soiis type, groundwater depth, age and history of maintenance of the system, and types of waste are a few. This test has been performed in an attempt to determine actuai soiI absorption capabiiities of your septic system under normaI useage by considering the degree of saturation of the leach field and surge ioads that might be imposed on =the system. This test can only evaIuate appar- ent performance at a given point in time, and cannot deter- mine either the condition of the Ieach fieid, seepage pit or other components of the septic system, or the depth of the water table. We appreciate the oPportunity given to perform this adequacy test. If you have any questions regarding this test, please contact this office. Very truly yours, ALASKA SOILS INVESTIGATIONS Stephen D.
