DATE; 08 (Rev. 4/85) ON-SITE WASTEWA TER DISPOSAL SYSTEM CONSTRUCTION PRACTICES and MA TERIAL SPEClFICATIONS REFERENCE: Riverview Estates Subdivision, Block 7, Lot 11 GENERAL: 1. The scope of this project includes the installation of a 1250 gallon septic tank and five foot wide drainfields to serve the proposed four bedroom residence for the referenced property. Construction shall be in accordance with the approved site plan and design drawings; Municipal permit with any spec/a/provisions or conditions; and ali 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. The septic tank shall be sufficiently bedded to prevent settling or shifting of the tank. Ali standpipes on the septic tank shall extend a m/n/mum of 12 inches above final grade. Page Two Riverview Estates Subdivision, Block 7, Lot 11 October 18, 1995 Septic tanks installed with less than 4 ft. of cover shall be insulated. A foundation cleanout shaft be installed one to four feet from the building foundation. In the line between the tank and the leachfield there shaft be two adjacent cleanouts (unless an effluent pumping system exists within the septic tank). These cleanouts shaft be located on undisturbed soil not more than 10 ft. from the tank. The first cleanout, in line, shafl be to clean toward the leachfield. The second ¢leanout shall be to clean toward the septic tank. Final grading over the septic tank shall be such that a positive slope exists a way from the septic tank. ABSORPTION TRENCH/DRAINFIELD INSTALLA T/ON: 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 m/n/mum 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 shaft 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 shaft 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 ever the trench must be mounded to prevent the formation of a depression after settling. Page Three Riverview Estates Subdivision, Block 7, Lot 11 October 18, 1993 MINIMUM MA TERIAL SPEClFICATIONS: 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: .Type of Pipe Perforated Solid. Cast Iron Yes ASTM D3034 (PVC) Yes ASTM F810 (HDPE) Yes ASTM D2662 (ABS) Yes Yes Yes No Yes Use of a type of pipe other than listed above must be approved by the inspecting engineer. Insulation shaft be at least 2" thick extruded direct burial polystyrene (Dow Chemical Company Styrofoam HI or equal). Septic tank inlets and out/ets shall be fitted with watertight couplings (Caulder, Femco, or equal). A permeable nontoxic silt barrier (Typar 3401, M/raft 140N, or equal) must be installed between the final leachfield gravel layer and the native soil backfill. Aft leachfield gravel (sewer rock) shaft be 0.5"-2.5" screened gravel with less than 3% passing the #200 sieve. When sand is being used as a filter mater/a/, it's gradation spec/f/cations must conform to current MoO. A. or D.E.C. requirements. Page Four Riverview Estates Subdivision, Block 7, Lot 11 October 18, 1993 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. 2. 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 least24 hours prior to the start of construction. If necessary, a Pre-construction meeting will take place on-site.
