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 fbr final grading areas subsequenfiy 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 nmst also receive prior approval fi~om 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. All 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. 17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASKA 99577 Page Two Lot 13, Block 5, Riverview Estates Subdivision August 27, 1997 A foundation cleanout shall be installed one to four feet fi'om the building foundation. In the line between the tank and the leachfield them shall be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shall be located on undisturbed soil not mom than 10 ft. from the tank. The fit'st cleanout, hi 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. LEACH]FIELD BED INSTAL[,ATION: Excavate the proposed Bed Area to the depth shown on the design. The bottom of the excavation shall be within 2 inches of level. If the bottom of the excavation becomes smem'ed, it must be raked or scratclled (ruffed-up) before gravel or sand placement. Ifa sand layer is requked, place sand over entire excavation to the required depth shown on the design. The top of the sand layer must be within 2 inches of level. Sewer rock shall be placed uniformly tl)roughout the entire bed. Perforated distribution pipe must be installed level with perforations down. Gravel depth below the perforated pipe shall be a minimum of six (6) inches. Gravel depth above the perforated pipe shall be a minimum of two (2) inches. The total gravel depth throughout the entire bed shall be a minimum of twelve (12) inches. The perforated distribution pipes must be no more than six feet apart. The distance between the outermost perforated distribution pipes and the sidewall of the absorption bed must be no more than throe feet. Silt ban'ier material mnst be installed between the final gravel layer and the native soil backfill. Ensure the silt barrier covers the entire gravel surface before placing bacld'~ll. Monitor tubes shall be of four (4) inch diameter, installed at the locations shown on the design, and extend a mirfiim~m of 12 inches above final grade. The portion of the monitoriug tube extending through the gravel depth shall be perforated six (6) inches below the bottom of the horizontal distribution lines. The monitoring tube should not extend below the bottom of the gravel surface. Backfill over the final gravel layer mt~st not be less than twenty-four (24) inches. Insnlation must be installed when the backfill depth is less than thirty-six (36) inches. The finished grade over the bed must be mounded to prevent the formation of a depression after settling. Page Three Lot 13, Block 5, Riverview Estates Subdivision August 27, 1997 MOUND SYSTEM INSTALLATION: 1. Any peat or organic matter must be removed from the elevated mound site. The bottom of the basal bed area as well as the top of the sand filter is to be within two inches of level. The distribution piping is to be ofPVC (ASTM D3034 or equal). All joints are to be solvent cemented. 4. The side slopes of the top layer of the mound system must not be steeper than 33% (3:1). The top of the mound shall be covered with a minimum of 6 inches of topsoil and vegetated sufficiently to prevent erosion. The distribution pipes are to be embedded in sewer rock. Care should be taken to bacl~ll in such a way as to prevent damage to the piping system. Silt barrier material must be installed between the final gravel layer and the native soil backfill. Ensure the silt ban'ier covers the entire gravel smi'ace before placing bat!dill. 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. MINIMUM MATERIAL SPECllTICATIONS: Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. The following pipe materials are approved for use in septic system installations in the Municipality of Anchorage: _T'_'_yp e of Pip_e Perforated Solid Cast ken Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No ASTM D2662 (ABS) Yes Yes Use ora type of pipe other than listed above must be approved by the inspecting engineer. Page Four Lot 13, Block 5, Rive~'view Estates Subdivision August 27, 1997 Inmlation 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 (Cautder, Feruco, 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 bacl~ll. 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 cmrent M.O.A. or D.E.C. requirements. INSPECTIONS: Typically there will be a minimum of three (3) inspections requh'ed 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 tile installation of any gravel. A septic tank may be set in place, but may not be baclc[illed before this inspection. The second inspection must be conducted after the placement of tile silt barrier, gravel, distribution lines, standpipes, cleanouts, and insulation, but before the placement of any other baclO~ll. 3. 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.-constraction meeting will take place on-site. The inspecting engineer will not coordinate, direct or control in any way the contractors actMties. The owner shall contract with the contractor to perform the work outlined in these specifications and pimps 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 owners 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 13, Block 5, Riverv/ew Estates Subdivision August 27, 1997 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 tiffs project or the failure of the contractor to can'y 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.
