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 fro/n soil settling. Contractors installing ~mtewater 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. 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 90577 Page 2 Lot 3, Block 1, Robin Hills Subdivision #3 August 10, 2001 All 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/DRAINFIELD 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 do~mward. 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, installed approximately in the locations shown on the design, and extend a minimum of 12 inches above final grade. The portion ofthe monitoring tube extending tl~ough 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 3 Lot 3, Block t, Robin Hills Subdivision #3 August 10, 2001 MINIMUM MATERIAL SPECIFICATIONS: Any septic tank proposed for installation must be constructed by a Municipal approved septic tank manufacturer. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: 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, Femco, 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, which ever requirement applies. INSPECTIONS: Typically there will be a minimum of three (3) inspections required during the installation of the ~vastewater disposal system. These inspections will occur as follows: Page 4 Lot 3, Block 1, Robin Hills Subdlvlalon #3 August 10, 2001 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. 3. The final inspection is to occur upon final grading of the property. Often them 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. 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.
