It is requested that you issue a permit to install a well and a septic system to serve the
TNSPECRON
proposed four bedroom dwelling on the referenced property.
Two test holes were excavated and percolation tests performed. The approximate locations
ENaNEERMSTUDIES
of the test holes are located on the attached site plan. At the time of excavation (5/27/04)
AWREPORTS
no water was found. After seven days of monitoring, ground water was not found.
We do not anticipate any adverse effects on neighboring wells, septic systems, reserve
WE MPECDON
areas or drainage patterns by the installation of the proposed septic system. The
aFLOWTEST
construction of this system will not prevent any future development on any of the adjacent
properties.

D19PECTION
GENERAL:
1. The scope of this project includes the installation of a 1300 gallon IIDPE
septic tank and a new trench to serve the proposed four bedroom residence
AWREroRTOsruDEs
located on the referenced property.
2. Construction shall be in accordance with the approved site plan and design
drawings, Municipal permit with any special provisions or conditions, and all
WEU E
E;"0"
applicable State and Municipal Wastewater Disposal Regulations.
3. The contractor shall be responsible for obtaining any necessary underground
utility locates.
urEPW6
4. Unless specifically agreed otherwise, the property owner shall be responsible
for final grading areas subsequently depressed from soil settling.
ROADOESIGN
5. 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 Ilealth
SM TEST
Department.

SEPTIC TANK INSTALLATION:

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.
5. 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.
6. 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.
2. 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 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.
4. 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
of the monitoring tube extending through 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.

MINIMUM MATERIAL SPECIFICATIONS:
1. Any septic tank proposed for installation must be constructed by a Municipal approved
septic tank manufacturer.
2. 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.
3. Insulation shall be at least 2" thick extruded direct burial polystyrene (Dow Chemical
Company Styrofoam HI or equal).
4. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Femco, or
equal).
5. 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.
6. All leachfield gravel (sewer rock) shall be 0.5"-2.5" screened gravel with less than 3%
passing the 4200 sieve.
7. 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.

Lot 3, Kyle & Erlea Subdivision
June 4, 2004
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:
1. 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.
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
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.
