ON-SITE WASTEWATER DISPOSAL SYSTEM CONSTRUCTION PRACTICES and MATERIAL SPECIFICATIONS CIVIL ENGINEERS (907) 694-2979 FAX (907) 694-1211 EFERENCE: Lot 12, Block 6, Valli Vue Unit No.2 June 13, 1997 GENERAL= me The scope of this project includes the installation of two five foot wide drainfields to serve the four bedroom residence on the referenced property. The existing septic tank is to be excavated, pumped, crushed, and abandoned completely, and replaced with a new 1000 gallon septic tank. The existing trenches are to be abandoned such that they may be used in the future. e Construction shall be in accordance with the approved site plan and design drawings, Municipal permit with any special provisions or conditions, and all applicable State and Municipal Wastewater Disposal Regulations. e The contractor shall be responsible for obtaining any necessary underground utility locates. Unless specifically agreed otherwise, the property, owner shall be responsible for final grading areas subsequently depressed from soil settling. On all leachfield mound systems, the property owner shall be responsible for ensuring a satisfactory vegetation growth over the mounded area. Contractors installing wastewater disposal systems must be certified by the Municipal Health Department for system installations. Owners installing their own systems must also receive prior approval from the Municipal Health Department. ~EPTIC TANK INSTALLATION: A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. 17034 NORTH EAGLE RIVER LOOP ' SUITE 204 · EAGLE RIVER, ALASKA 99577 'Page Two Lot 12, Block 6, Valli Vue Unit No. June 13, 1997 e Ail standpipes on the septic tank shall extend a minimum of 12 inches above final grade. Septic tanks installed with less than 4 ft. of cover shall be insulated. A foundation cleanout shall be installed one to four feet from the building foundation. In the line between the tank and the leachfield there shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not more than 10 ft. from the tank. The first cleanout, in line, shall be to clean toward the leachfield. The second cleanout shall be to clean toward the septic tank. Final grading over the septic tank shall be such that a positive slope exists away from the septic tank. ABSORPTION TRENCH/DI~AINFIELD INSTALLATION= Excavate the proposed trench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level. If the sidewalls of the excavation become smeared, they must be raked or scratched (roughed-up) before gravel (sewer rock) placement. ® Once the gravel is installed, the distribution pipe is to be installed level with the perforations faced downward. Gravel is then to be placed over the distribution pipe to provide a minimum of 2 inches of cover over the pipe. ® A silt barrier must be installed between the final gravel layer and the native soil backfill. Ensure the silt barrier covers the entire gravel surface before placing backfill. e Monitor tubes shall be of four (4) inch diameter, installed approximately in the locations shown on the design, and extend a minimum of 12 inches above final grade. The portion of the monitoring tube extending through the gravel shall be perforated from the bottom of the trench to the invert of the distribution pipe. This is equivalent to the effective depth of the gravel as noted on the design. 'Page Three Lot 12, Block 6, June 13, 1997 Valli Vue Unit No. 2 Backfill over the final gravel layer must not be less than twenty-four (24) inches. Insulation must be installed when the backfill depth is less than thirty-six (36) inches. The finish grade over the trench must be mounded to prevent the formation of a depression after settling. MINIMUM MATERIAL SPECIFICATIONS~ Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. e The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: Type of Pipe Perforated Soli~ Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). e Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or equal). A permeable nontoxic silt barrier (Typar 3401, Mirafi 140N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. ® All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3% passing the #200 sieve. When sand is being used as a filter material, its gradation specifications must conform to current M.O.A. or D.E.C. requirements. Page Four Lot 12, Block 6, June 13, 1997 Valli Vue Unit No. 2 INSPECTIONS: Typically there will be a minimum of three (3) inspections required during the installation of the wastewater disposal system. These inspections will occur as follows: The first inspection must be conducted after the excavation of ditches, pits, trenches, or beds and before the installation of any gravel. A septic tank may be set in place, but may not be backfilled before this inspection. The second inspection must be conducted after the placement of the silt barrier, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other backfill. The final inspection is to occur upon final grading of the property. Often there will be more than these 3 inspections required. Especially with the installation of multiple trenches, sand filters, pressurized distribution systems, etc. Thus, the inspecting engineer is to be contacted at least 24 hours prior to the start of construction. If necessary, a pre-construction meeting will take place on-site. The inspecting engineer will not coordinate, direct or control in any way the contractors activities. The owner shall contract with the contractor to perform the work outlined in these specifications and plans and in accordance with the attached M.O.A. permit. There will be no contractual arrangement existing between the contractor and S & S Engineering. S & S Engineering shall be the owner's representative and will inspect the work as stated above to document the contractors activities. Final acceptance of the contractors work rests with the owner and the M.O.A. Page Five Lot 12, Block 6, Valli Vue Unit No. June 13, 1997 2 S & S Engineering shall have no liability to the owner or to others for acts or omissions of the contractor or any other persons performing work on this project or the failure of the contractor to carry out the work in accordance with these construction documents. S & S Engineering's inspecting engineer will not be responsible for the construction means, methods, techniques, sequence, procedures or the safety precautions incident to this project.

Fred Schroeder SRA Box 31E 6741 Roundtree Drive Anchorage, AK 99507 Re: Adequacy Test for Existing Septic System on Lot 12, Block 6, Valli Vue No. 2. Dear Mr. Shroeder': At the request off your agent, Ms. Bonnie Mehner of Jack White Co., our office conducted a percolation adequacy test on your existing septic system at the above-referenced location during the period September 10-12, 1980. You reported that your septic system con- sists of a lO00-gallon septic tank and a seepage pit. During the test, it was reported that the septic tank had been pumped just prior to the percolation adequacy test. However, since the 3-bedroom house had been occupied up to the time of the test, a normal degree of saturation within the leach Field is assumed. In accordance with the Anchorage Municipal Code, Chapter 15.65, Waste Water Disposal Regulations~ any on-site sewage disposal system "shall have adequate capacity to properly dispose of the maximum daily sewage flow." The maximum daily flow is computed at 75 gallons per capita-day (gcpd). Since "the population of dwellings shall be estimaled at two persons per sleeping room," the maximum daily sewage flow for your 3-bedroom house is 450 ga~ons per day (gpd). To test lhe soils absorption capacity of your system, 110 percent of the maximum daily flow or 500 gallons of clear water was added in 50-gallon increments to the seepage pit. The waler was obtained From the 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. Fre~ Sehroeder September 15, 1980 Page -2- The attached Table of Test Data represents the depths of liquid in the septic tank and seepage pit, and the quan- tities of water added. The septic tank was determined to be 8.4 feet deep (bottom of tank to ground surface) with an initial depth of 2.5 feet in the tank. The seepage pit was measured to be 13.2 feet deep with an initial depth of 4.2 feet. Ground elevation at the septic tank standpipe is approximately 0.3 feet above 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 Bay 2 fell to 2.8 feet above its initial static level on Day 1, during a recovery period of 24 hours. On Bay 3, the level had fallen to 0.5 feet above its static level on Bay 2, during a recovery period of 24 hours. The liquid level in the seepage pit saw a net increase in elevation of 3.3 feet during the course of the test. On Day I of the percolation adequacy test, 500 gallons of water was added to seepage pit. A rise in liquid level in pit of 3.8 feet was observed; 'on Day 2 the liquid level had only fallen 1.0 feet indicating a disposal rate of 131 gpd. On Day 2 of the test~ an additional 500 gallons was added to the pit. A rise of 2.3 feet was observed in the pit~ at which time the water started overflowing into the septic tank. Approximately 300 gallons had been added to the pit at this point. Since the septic tank had been pumped just prior to the test and was less than full, the 200 gallons which over- flowed into the tank could not drain back into the seepage pit. Therefore, only 300 gallons was available for percolation on Day 2. The 2.2 foot rise and 1.8 foot fall in liquid level for the 300 gallons of water available on Day 2 indicates a disposal rate of 231 gpd. Based on two days of testing, an average percolation rate flor your existing septic system of approximately 180 gpd is indicated. Since an on-site sewage disposal system for a 3-bedroom dwelling must be capable of disposing of 450 gallons of sewage per day, your septic system does not appear to be functioning satisfactorily at this time. Many factors affect the operation of a soil absorption type of sewage disposal system. Soil 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 Mr'. Fred Shroeder 'September 15, 1980 Pag8 -3- to determine actual soil absorption capabilities of your septie system under normal useage by considering the degree of saturation of the leach field and surge loads that might be imposed on the system. This test can only evaluate appar- ent performance at a given point in time, and cannot deter- mine either the condition of the leach field~ 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 eontaot this office. Very truly yours, ALASKA SOILS INVESTIGATIONS 'Stephen D.
