It is requested that you issue a permit to install a new septic system to serve the
proposed three bedroom dwelling on the referenced property. The existing house will
be removed prior to septic installation, the existing septic system abandoned
completely, and the existing community water service will be extended to the new
house.
A test hole was excavated and a percolation test performed. Thc approximate location of
thc test hole is located on thc attached site plan. At thc time of excavation 8/6/07, ground
water was not found. After monitoring, no ground water was found.
We do not anticipate any adverse effects on neighboring wells, septic systems, reserve
areas or drainage patterns by the installation of the proposed septic system. The
construction of this system will not prevent any future development on any of the adjacent
properties.
Ifyou require additional information, please contact us.

August 29, 2007
GENERAL:
The scope of this project includes the installation of a new 1000 gallon HI~PE
septic.tank and a septic trench to serve the proposed three bedroom residehce
locat6d on the referenced property. ~
Construction shall bc in accordance with the approved site plan and design
drawings, Municipal permit with any special provisions or conditions, and all
applicable State and Municipal Wastcwater 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. :
Contractors installing wastewater disposal systems must be certified by lthc
Municipal Development Services Department or ADEC if required, for
system installations. Owners installing their own systems must also receive
prior approval from the respective agency.
SEPTIC TANK INSTALLATION:
A septic tank is to be constructed by a certified septic tank manufacturer.
Construction shall include two 4" clcanouts for pumping access. All HDPE
septic tanks are required to have a 4" monitoring pipe installed next to the
tank extending to the bottom of the tank.

LotS;CollettTrect;$ectlon 31;T15N; RIW
August29,200?
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.
Septic tanks installed with less than 4 tL of cover shall be insulated. All HDPE septic
tanks are required to be covered with a minimum of 2" direct burial insulation, and a
maximum of 4 feet ofcover.
A foundation eleanout shall be installed one to four feet from the building foundation. In
the line between the tank and the leaehfield 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 eleanout, 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.
ABSORPTION TRENCII/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 (rafted-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 disU'ibution 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.
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:
I. 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 OtDPE) Yes No
ASTM D2662 (ABS) Yes Yes
Use of a 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 HI or equal).
Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Femco, 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 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 M.O.A. or D.E.C. requirements, which ever requirement applies.

August 29, 2007
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.
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-
consu'uction 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. pc,mit. There will be no contractual
an'angement 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 Engineefing's
inspecting engineer will not be responsible for the construction means, methods, techniques,
sequence, procedures or the safety precautions incident to this project.
