field is approved to be 13.4 feet to the future alternate field for Lot 14.
This waiver approval applies to the existing absorption field only. Any future upgrade to the on-

Absorption trench to lot line, Absorption trench to alternate field (Lot 14)
Dear On -Site Services Engineer:
We are working to document the existing system that was installed in 2003 under an approved
pen -nit. After receiving the survey, we have discovered that the end of the trench was placed 3.4'
from the eastern property line. This places it 13.4' from the alternate site later designated on
neighboring Lot 14, while it should have 17' separation.
The soils in that area are noted as SM/ML with a percolation rate of 26.7 minutes per inch. This
indicates that there are enough fines in the sand that the sidewalls of an excavation will not quickly
collapse. The trench can be excavated if needed in the future with the use of trench boxes or other
slope protection without affecting the neighboring lot. In addition, there is enough room on the
neighboring lot for separation to the existing system.
While the alternate site on the neighboring lot has been mistakenly placed too close to this existing
trench, this is mitigated by the end-to-end orientation (instead of parallel trenches). Also, the
neighbors can still build that trench using alternate construction techniques and materials (such as
an impermeable layer on the end nearest this trench).
We hereby request that waivers be issued for the 3.4' to the property line and 13.4' to the alternate
field on Lot 14.
Sincerely,
Benjamin Schiller, P.E.

As I said this morning, if this were a building permit plan review, we have the following statement offered to clarify our
position on said encroachment:
The owners are put on notice the shed, fence, or other structure is an unpermitted encroachment into the Utility, Public
Use, or Drainage Easement, and ROW is not enforcing it at this time. Should the encroaching item(s) need moving or the
owners want to replace them, the final location needs to be out of the easement(s).
We hope this is sufficient for your COSA purposes.

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.
3. 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 Pine Perforated Solid
Cast Iron
Yes
Yes
ASTM D3034 (PVC)
Yes
Yes
ASTM F810 (IIDPE)
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 #200 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.
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:
Page 4
Lot 13, Block 1, Williamson Subdivision 01
May 16, 2003
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.
