It is requested that you issue a permit to install a new(upgrade) 1300 gallon IIDPE
septic tank and deep trench septic system to serve the existing four bedroom house on
the referenced property. A flmv diverter vah'e will be installed to allow the existing
trench to be used at a later date.
A test hole was excavated and a percolation test performed. The approximate location of
the test hole is located on the attached site plan. At the time ofexcavation (5/3/2005) water
was found at 16 feet. After seven days of monitoring, ground water was found at 13.6
feet.
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 g~ll not prevent any future development on any of the adjacent
properties.
Ifyou~ditional information, please contact us.

MATERIAL SPECIFICATIONS

March 26, 2010
GENERAL:
The scope of this project includes the installation of a new(upgrade) 1300
gallon HDPE septic tank and a deep septic trench to serve the existing four
bedroom residence located on the referenced property. A flow diverter valve
will be installed to allow the existing trench to be used at a later date..
Construction shall be in accordance with the approved site plan and design
drawings, Municipal permit with any special provisions or conditions, and all
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 o~ncr shall be responsible
for final grading areas subsequently depressed from soil settling.
Contractors installing wastewater disposal systems must be certified by the
Municipal Development Services Department or ADEC if required, for
system installations. Owners installing their o~x~ 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" cleanouts for pumping access. All tIDPE
septic tanks are required to have a 4" monitoring pipe installed next to the
tank extending to the bottom of the tank.
15861 $. Blrchwood Loop Road - C. huglak, Alaska 99567
Page 2
Lot 4; Johnson Heights Phase #2 S/D
March 26, 2010
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 ft. 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 of cover.
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 I0 ft. from the tank. The first cleanout, in line,
shall be to clean toward the leachfield. The second cleanout shall be to clean toxvard the
septic tank.
Final grading over the septic tank shall be such that a positive slope exists away from the
septic tank.
ABSORPTION TRENCtl/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. 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
ofthe monitoring tube extending through the gravel shall be perforated from the bottom of
the trench to the invert ofthe 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.

Lot 4; Johnson Heights Phase #2
March 26, 2010
MINIMUM MATERIAL SPECIFICATIONS:
Any septic tank proposed for installation must be constructed by a Municipal approved
septic tank manufacturer.
o
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 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, Feruco, 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.
e
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 4; Johnson Heights Phase
March 26, 2010
INSPECTIONS:
Typically them will be a minimum of three (3) inspections required during the installation of the
wastew~ter 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 grovel. 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 ofany 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 gSth the owner and the M.O.A.
S & S Engineering shall have no liability to the owner or to others for acts or omissions &the
contractor or any other persons performing work on this project or the failure &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.
