MATERIAL SPECIFICATIONS
Lot 2A, Ryle and Erica S/D
September 14, 1995
1. The scope of this project includes the installation of
a 1000 gallon septic tank and two five foot wide
drainfields to serve the proposed three bedroom
residence for the referenced property.
2. 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.
3. The contractor shall be responsible for obtaining any
necessary underground utility locates.
4. Unless specifically agreed otherwise, the property
owner shall be responsible for final grading areas
subsequently depressed from soil settling. On all
leachfield mound systems, the property owner shall be
responsible for ensuring a satisfactory vegetation
growth over the mounded area.
5. 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.
ISEPTIC TANK INSTALLATION:
1. A septic tank is to be constructed by a certified
septic tank manufacturer. Construction shall include
two 4" cleanouts for pumping access.
2. The septic tank shall be sufficiently bedded to
prevent settling or shifting of the tank.
3. All standpipes on the septic tank shall extend a
minimum of 12 inches above final grade.
17034 NORTH EAGLE RIVER LOOP • SUITE 204 • EAGLE RIVER, ALASKA 99577
Page Two
Lot 2A, Kyle and Erica S/D
September 14, 1995
4. Septic tanks installed with less than 4 ft. of cover shall
be insulated.
5. 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.
6. Final grading over the septic tank shall be such that a
positive slope exists away from the septic tank.
ABSORPTION TRENCH/DRAINFILLD INSTALLATION:
1. 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.
5. 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.
Page Three
Lot 2A, Kyle and Erica S/D
September 14, 1995
MINIMUM MATERIAL SPECIFICATIONS:
1. Any septic tank proposed for installation must be
constructed by a Municipally 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 (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.
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, Fernco, 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 leach.field 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.
Page Four
Lot 2A, Kyle and Erica S/D
September 14, 1995
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:
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.
