Se The scope of this project includes the installation of a 1500 gallon wast·water S.T.E.P. system (septic tank) and a pressurized absorption bed to serve the four bedroom residence located on the referenced property. The existing leachfield is to be abandoned completely. 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 Wast·water 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. 17034 NORTH EAGLE RIVER LOOP · SUITE 204 · EAGLE RIVER, ALASKA 99577 Page Two Lot 1, Block 4, Henkins Subdivision January 26, 1996 e e 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. 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. LEACHFIELD BED INSTALLATION: 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 smeared, it must be raked or scratched (ruffed-up) before gravel or sand placement. e If a sand layer is required, 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. Se Sewer rock shall be placed uniformly throughout the entire bed. The distribution piping is to be of PVC (ASTM D3034 or equal). All joints are to be solvent cemented. Gravel depth below the distribution pipes shall be a minimum of six (6) inches. Gravel depth above the perforated pipe shall be a minimum of two (2) inches. o The distribution piping must be as shown on the design. The distance between the outermost perforated distribution pipes and the sidewall of the absorption bed must be no more than three feet. Page Three Lot 1, Block 4, Henkins Subdivision January 26, 1996 Se St Silt barrier material must be installed between the final gravel layer and the native soil backfill, unless insulation is used, then the silt barrier should be installed over the insulation. Ensure the silt barrier covers the entire gravel surface before placing backfill. Monitor tubes shall be of four (4) inch diameter, installed at 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 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 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 finished grade over the bed 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 Cast Iron ASTM D3034 (PVC) ASTM F810 (HDPE) ASTM D2662 (ABS) Perforated Solid Yes Yes Yes Yes Yes No 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). Page Four Lot 1, Block 4, Henkins Subdivision January 26, 1996 6e 7e 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, its gradation specifications must conform to current M.O.A. or D.E.C. requirements. 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. e 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. Page Five Lot 1, Block 4, Henkins Subdivision January 26, 1996 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.
