The test indicates acceptance rates determined, under conditions at the time tested. Actual system performance over long periods of time depend on factors which cannot be evaluated by this test thus our office cannot warrant the suitability or fitness of the system for either an extended period of time or for user demand in excess of the expected flow noted herein. Factors affecting system performance include: Actual use demand on the system} Flucuations in groundwater levels; Physical conditions of the septic tank, leach field, trench or seepage pit and soil. It should be noted that while a septic tank and leach field disposal system is one of the most reliable methods of sewage treatment and disposal it is nearly certain that the leach field or seepage pit will fail sometime during the useful life of the structure. Studies incidate leach fields, trenchs and pits have a life expectancy of ten to twelve years under optimum conditions. All septic systems have a finite hydraulic loading capacity which can be expected to decrease with time. Because the house on the lot is occupied, we assume that the seepage pit was at its normal degree of saturation. During this test the liquid level in ANCHORAGE FAIRBANKS Ms. Joan Huber Page -2- the septic tank was monitored as water was added to the system. The measurements are summarized in the following table: Time Total Gallons Added 10:30 2.50 0 10:55 2.05 30 11:05 2.30 30 11:20 2.50 30 11:30 2.60 30 11:40 2.70 30 11:50 2.75 30 12:00 2.75 30 12:15 1.90 50 12:30 2.25 50 12:40 2.35 50 12:50 2.50 50 The meter used during the test was a Rockwell 5/8" standard water meter which had previously been calibrated by R&M Consultants, Inc. If the 3 bedroom residence on the property is to house 6 people, the average load on the system can be expected to be 450 gallons per day or 0.31 gallons per minute. During the test, the system accepted 50 gallons in 140 minutes. This indicates an average, effluent acceptance rate of approximately 0.36 gallons per minute at the time of the test. We can therefore conclude that the system is disposing of effluent at an adequate rate for a 3 bedroom residence. We appreciate this opportunity to be of service to you.

Circle Anchorage, Alaska 99507 Subject: Soil Investigation for Sanitary Sewer System, Lot 13, Block 7, Granite View Subdivision, Anchorage, Alaska. Dear Ms. Huber: At the request of Eila Mae Warren, from Nova Reality on July 7, 1980, R&M Consultants conducted a subsurface soils investigation at the proposed location of the sanitary sewer system on the subject lot. The test procedure complied with those required by the Municipality of Anchorage, Department of Health and Environmental Protection. The site topography was gently sloping to the southwest. At the time of the investigation, a system existed as indicated on the enclosed sketch. The ground cover in the area of investigation was lawn. Field activities were performed on July 25, 1980. Two test holes were ex cavated using a backhoe. The test holes were sited as determined by field conditions and their locations are shown on the attached sheet. Test Hole 01 was excavated to a depth of 4 feet. Test Hole ~2 was excavated to a depth of 12 feet, and the percolation test was performed at this location. The depth indicated is below the existing ground elevation at the time of drilling. The soils were inspected at the time of excavation by Phil Baldner, a technician from our office. Grab samples were taken to the laboratory and were visually classified. The description of the soils encountered are shown on the attached sheets. Bedrock was not encountered at the location of the test holes. At the time the test holes were excavated, seasonal frost was not present and permafrost was not encountered. Test hole #1 was in the location of what appeared to be a leach field. No pipes were encountered and no water was flowing through the material, however, it was evident that septic effluent was present. ANCHORAGE FAIRBANKS JUNEAU VALDEZ WA$1LLA July 29,.' 1980' Ms..Joan. Huber · P~ge -2- Groundwater after drilling was at a depth of 8 feet in Test Hole ~2. It should be noted that the information given in this report displays specific conditions encountered on the date of the investigation. Subsurface conditions may vary on other parts of the lot without any apparent super- ficial evidence of the change. Groundwater level may fluctuate both seasonally and from year to year. A percolcation test was performed from a depth indicated on the soils log (sheet ~2). The average infiltration in the stratum tested was measured over one hour. The net drop in the water level that occured during the final 30 minutes was used to calculate the percolation rate. The measured percolation rate was 20 minutes per inch. We appreciate this opportUnity to be of service to you. Please contact us if you have any questions concerning this letter or if we can be of additional service. Sincerely, R&M CONSULTANTS, INC.

Lexington Circle Anchorage, Alaska 99502 August 20, 1980 SOIL AND MATERIALS ENGINEERING AND TESTING 907-276-4113 Department of Health and Environmental Protection 825 L Street Anchorage, Alaska 99501 Attention: Les Buchholz Gentlemen: In behalf of Ms. Joan Huber, we submit the attached sketches of the proposed on-site sewer system for your approval. As you know, the existing system on Lot 13, Block 7, Granite View Subdivision was found to be inadequate when Ms. Huber was required to test the system prior to selling the house. R & M Consultants have performed a soils log and percolation test. Based on these data the DHEP designed a drainfield, however the geometry of the lot complicated the installation of the system. We were called by Ms. Huber when it appeared that complications were developing. The existing sewer system appears to be in the only space available on the lot for development without conflicting with the well protection radius. The information regarding the sewer system of Lot 4, Block 7 in the files of DHEP indicates that the well could not be located substantially northwest of its present location. The location of the well on Lot 12 is very close to the'location of Ms. Huber's well, so it is the writer's opinion that little could be gained from the reloca- tion of Ms. Huber's well. We drilled one test hole near the previous soils test to verify the depth to water which we observed to be 7.3 feet. Department of Health and Environmental Protection August 20, 1980 Page Two As shown on the attached sketches to install the system as designed by the DHEP we will need to obtain a variance from Municipal Code and/or standard practice, (1) to install the drainfield immediately adjacent to the property lines; (2) to use the existing septic tank which is within 100' of the well; (3) to use the additional tank capacity required by ordinance in a dual use of a dosing tank and septic tank; (4) to install~ the drainfield beneath the driveways; and (5) to install drainfield over areas previously used for the cribs. The attached sketches show the intended layout and details of the dosing tank and distribution ditch. The remainder of this letter addresses each variance request on a point-by-point basis. (1) Presently the area east of South Circle Way is undeveloped. The R.O.W. is 60', therefore the zero separation to lot line variance will minimally affect future development to the east. ~ Both the wells and sewer systems of the neighbors to the north and south are well outside the influence of the proposed system. (2) The existing septic tank was installed long before the minimum separation of 100' was required. The separation is approximately 75 feet. The system is estimated to be 14 years old and the laboratory report indicates no contamination of the existing well. Department of Health and Environmental Protection August 20, 1980 Page Three (3) We desire to dose the drainfield once daily to avoid freezing of the lines and provide better treatment of the effluent. A considerable savings can be obtained by dual use of the required extra tank capacity by dual use of this tankage as a dosing tank. This will reduce the detention time by an average of one half day (@ 450 gpd and dosing once a day), however, it is our intent to provide more of an aerobic regime in the drainfield to offset the loss of detention treatment. (4) Drainfields will be insulated with high density styrofoam board to prevent freezing and 2" Schedule 40 PVC pipe will be used in the drainfield to resist crushing. (5) DHEP design requires 188 L.F. of trench. To avoid digging out the existing cribs, and the attendant disposal problems, we plan to install approximately 230 feet of trench with the extra length to offset areas previously saturated Or affected by the existing cribs. We trust the foregoing is sufficient to your needs. It is the writer's opinion that the proposed layout is the most practical positive solution to an unfortunate problem arising from both on-site wells and sewer systems on small, subdivision lots. Please call if there are any questions or if we can be of further service. Your aid in expediting the process on these waivers and your approval of this system is appreciated.
