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. 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. SEPTIC TANK INSTALLATION: A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall include two 4" cleanouts for pumping access. e The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. Ail standpipes on the septic tank shall extend a minimum of 12 inches above final grade. 4. Septic tanks installed with less than 4 ft. of cover shall be insulated. Page Two Sue Tawn Estates Subdivision June 20, 1993 #2, Block 4, Lot 2 e 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 T~ENCH/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 ruffed- 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. Monitor tubes shall be of four (4) inch diameter and installed approximately in the locations shown on the design. 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. ® 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. Page Three Sue Tawn Estates Subdivision %2, Block 4, June 20, 1993 Lot 2 MINIMUM MATERIAL SPECIFICATIONS: Any septic tank constructed by a manufacturer. proposed for installation must be Municipally approved septic tank The following septic system Anchorage: pipe materials are approved for use in installations in the Municipality of Type of Pipe Perforated Solid 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). 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. Ail 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, it's gradation specifications must conform to AMC 15.65.060D. Page Four Sue Tawn Estates Subdivision ~2, Block 4, June 20, 1993 Lot 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. me 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. Se 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. Municipality of Anchorage DEPARTMENT OF HEALTH & HUMAN SERVICES 825 "L" Street.

To Whom It May Concern: I would like to install my own septic system on Lot 2, Block 4, Sue Tawn Estates. I have received a permit from your agency, (Permit #SW90196) authorizing the installation. Per the Municipality's "Construction Practices and Material Specifications" letter, under "General", and paragraph 5, I must receive authorization from your agency to perform this work. I understand the concern that your agency has for the proper installation of septic systems in the Municipality. I would like to outline my plan for the installation on this system which will meet code, and will be inspected according to the required schedule by S & S Engineering. 1. My lot is predominantly sand and gravel with some medium sized sto~es. When I dug my test hole and water line from my well, the walls of the trench were firm and very little of the wall sloughed off during this work. When I install the leachfield and tank, I am sure that I can expect the same. This affords me a high degree of safety, and assures you that there will be a solid 7' bed of sewer rock. 2. The septic system designed by S & S Engineering is a straight forwaYd design with a simple leachfield consisting of 54' of perforated pipe in a straight line. As this is easily dug and backfilled, and since a sand bed or multiple trenches are not required, installation should be able to be completed quickly and easily. i Page 2 Application for Owner/Builder Wastewater Disposal System 3. My objective in the building of my house is to insure that whatever I put on my land meets code and adds to the value of the property. Under this premise, I will not compromise any system that would detract from the livability and subsequent saleability of this property. In addition, I will be installing many com- ponents that afford the septic system, and myself, a extra edge for ease in use. I will be insulating the line from my house to the tank to prevent freezing. I also planned for easy access for pump trucks to my tank for easy cleaning without landscape destruction. Lastly, my qualifications include the installation of plumbing and wastewater systems in the Chugiak area. I have many hours of experience on heavy equipment, including backhoes, the main piece of equipment on this project. I am confident that I will be able to complete this project in two to three days, and I assure you that I will work closely with the engineers at S & S to insure I meet the Anchorage code. Thank you for reviewing this application. Sincerely, a4� Development Services Department On -Site Water &Wastewater Section Certificate of On -Site Systems Approval Parcel I.D. 051-511-42 1.
