The property has enough area for a future septic upgrade which can be seen on the attached site
plan. We do not anticipate any adverse effects on neighboring wells, septic systems or
drainage patterns by the installation of the proposed septic system.
There are no points of contamination within the proposed well radius that can be seen on the
attached site plan.
If you require additional information, please contact us.

REFERENCE:
GENERAL:
Lot 14, Roehl Subdivision
October 30, 1998
The scope of this project includes the installation of a 1000 gallon septic tank and
leachfield trench for the proposed two bedroom house to be located on the referenced
property.
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 owner shall be responsible for final
grading areas subsequently depressed from 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 manufacturer. Construction
shall include two 4" cleanouts for pumping access.
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.

Page 2
Lot 14, Roehl Subdivision
October 30, 1998
Septic tanks installed with less than 4 fl. of cover shall be insulated.
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.
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.

Lot 14, Roehl Subdivision
October 30, 1998
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 septic system installations in the
Municipality of Anchorage:
Type of Pipe Perforated Solid
Cast Iron
ASTM D3034 (PVC)
ASTM F810 (aD?E)
ASTM D2662 (ABS)
Yes Yes
Yes Yes
Yes No
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 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.
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.

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, eleanouts, 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.
