RE: SEPTIC SYSTEM UPGRADE PERMIT
LEGAL: OUR MOUNTAIN BLOCK 2, LOT 11
The property owner has requested we obtain a permit to upgrade the failed septic system of the
above referenced lot. We propose to install one shallow trench and 1000-gallon HDPE deep
burial septic tank to serve the existing 3-bedroom residence. We would recommend a 1500-
gallon HDPE tank be installed for current functionality and future consideration or flexibility.
The design is based on the recent test holes conducted on September 26, 2025, and MOA record
document test hole #2 performed in April 1999 by Robert C. Cowan, PE. No groundwater was
observed at test hole excavation or monitoring of any of these test holes.
The slopes are moderate at 11-16% at the proposed upgrade location. The lot and area are served
by private & public water. Any encroaching well radii, property lines, easements or other
required separations will be staked and verified prior to construction. The design will not impact
any of the neighboring properties. Please contact us if you have any questions.
Sincerely,
Curtis Huffman, P.E.

REFERENCE: Lot 11, Block 2, Our Mountain Subdivision
Request you issue a permit to drill a well and install a septic system to serve the
proposed three bedroom dwelling on the referenced property
Two test holes were excavated and percolation tests performed. The approximate
location of the test holes are located on the attached site plan.
At thc time of excavation 3/29/99 water was not found. After seven days of ground
water monitoring the monitoring tube was dry.
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.
If you require additional information, please contact us.

GENERAL:
The scope of this project includes the installation of a 1000 gal'.on septic tank and
leachfield trench for the proposed three bedroom house located on the referenced
property.
Construction shall be in accordance with the approved site pla,~ and design drawings,
Municipal permit with any special provisions or conditions, and all ~,pplicable 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 fi.om soil settling.
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 manufaclurer. Construction
shall include two 4" cleanouts for pumping access.
The septic tank shall be sufficiently bedded to prevent settling or shining 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 fL of cover shall be insulated.
A foundation cleanout shall be installed one to four feet bom 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 I0 fL 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.
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.
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.
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:
Any septic tank proposed for installation must be constructed by a Municipal approved
septic tank manufacturer.
The following pipe materials are approved for use in septi~ system installations in the
Municipality of Anchorage:
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.
Insulation shall be at least 2" thick extruded direct burial polyst~Tene (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 leaehfield 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.
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 11, Block 2, Our Mountain S/D
Apr 8, 1999
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 bacldilled 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-construction meeting will take place on-site. The inspecting engineer xvill no.t 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.'
