CML ENGINEERS (907) 694-2979 FAX (907) 694-12t t REFERENCE: l.ot I, Block3, GENERAL: The scope of this project includes the verification or installation of a 1000 gallon septic tank and installation of un absorption bed to serve the existing three bedroom residence located on the referenced property. 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 bc responsible for final grading areas subscqucndy depressed from soil settling. On all leachficld mound systems, the property owner shall bc responsible for cnstning 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. 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 2 Lot 1, Block 3, Knlk V~ew Estates Jury IS, 2002 3. 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. A foundation cleanout shall be installed one to four feet from the building foundation. In the line between the tank and the leachfield them shall be two adjacent cleanouts. 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. LEACIlFIELD 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 (rafted-up) before gravel or sand placement. Ifa 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. Sewer rock shall be placed uniformly throughout 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 three feet. Silt barrier material 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 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 ofthe 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 ora depression after settling. Page 3 Lot 1, Block 3, Knlk View Estates July 16, 2OO2 8. A mound system is to have the upper six inches of top soil and be seeded for vegetation. A subsurface disposal field may not be located on a slope greater than 25 percent unless there is an approved exception documented. MINIMUM MATERIAL SPECIFICATIONS: 1. Any septic tank proposed for installation must be constructed by a Municipally approved septic tank manufacturer. 2. The following pipe materials are approved for use in septic system installations in the Municipality of Anchomge: Type of Pipe Perforated Solid Cast Iron Yes Yes ASTM D3034 (PVC) Yes Yes ASTM F810 (HDPE) Yes No AS'I'M D2662 (ABS) Yes Yes Use ora type ofpipe 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 ttI or equal). Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Femco, or equal). A permeable nontoxic silt barrier (Typar 3401, Mimfi 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 MOA requirements. INSPECTIONS: Typically there will be a minimum of three (3) inspections required during the installation of the wastewater disposal system. These iuspectious will occur as follows: Page 4 Lot 1, Block 3, Knlk View £s~ates July 18, 2002 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, eleanouts, and insulation, but before the placement of any other backfill. 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-construction meeting will take place on-site. The inspecting engineer will not coordinate, direct or conlxol 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 MOA permit. There will be no contractual arrangement existing between the contractor and 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. 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.
