Subject: New sewer/well permit —T15N R1W SEC 9 LOT 107
Gentlemen:
The owner has requested we proceed forward to obtain aseptic permit on the subject
lot. On November 9, 2006 one testhole was performed for the proposed system. The
results of this test are attached. The general slope of this lot is from east to west at a
grade of approximately 3-5%. The existing undocumented system has been
disconnected from the residence and abandoned in place per code. Three low
producing, nonconforming wells are to be decommissioned and a new well drilled in
the northeast portion of the lot.
We have designed our system utilizing the existing testhole that was excavated for the
existing 3 -bedroom house. The lot will be served by an individual well, located on the
northern portion of the lot. We propose to install two 5' wide shallow trenches. Water
was encountered during the excavation at 6, and during monitoring at 5'.
There are no public or private wells within 200' of our proposed system location except
as noted. There is no surface water within 100' of the proposed system and there are no
known curtain drains within 50'. We do not expect there to be any adverse effect on
adjacent lots by the development of this system.
If you have any questions, please contact me at 696-6111/FAX 696-8111.

single family residence on the referenced property as delineated on the attached Municipality of
Anchorage (MOA) permit and site plan.
1. Construction shall be in accordance with the approved site plan and design drawings; MOA
permit with any special provisions or conditions, and all applicable State and Municipal
Wastewater Disposal Regulations.
1. KND Engineering Inc (KND) assumes no responsibility of the accuraty of the as -built survey
provided by the owner or owner's representative.
1. The owner or contractor is responsible to notify the engineer of any discrepancies noted on the
design plans or drawings prior to commenting
or These discrepancies could be, but not
limited to, possible encroachments, surface water, varying soils, unplatted easements, types or
use of dwellings on or adjacent to property, nearby public wells, etc.
1. The contractor shall be responsible for locating any necessary underground utilities, easements,
property lines and surface water. The owner and/or contractor shall ensure, if deemed
appropriate, that a registered land surveyor prior to construction flags all setbacks.
1. The contractor shall be responsible for verifying all pertinent
component layout. separation distances and
1. 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.
1. The MOA Development Services Department On -Site Water 6r Wastewater Program must
certify contractors installing wastewater disposal systems. Owners installing their own systems
must also receive prior approval from said MOA Department.
SEPTIC TANK / HOLDING TANK / LIFT STATION INSTALLATION:
1. A septic tank is to be constructed by a certified septic tank manufacturer. Construction shall
include two 4" cleanouts for pumping access.
1. The septic tank shall be sufficiently bedded with proper material and compacting to prevent
damaging, settling or shifting of the tank
1. All standpipes on the septic tank shall extend a minimum of 12 inches above the final grade.
1. Septic tanks installed with less than 4 foot of cover shall be insulated. The contractor will
ensure that the fill over the tank does not exceed the burial depth rating.
1. 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 feet from the tank. The second cleanout, in line, shall be to clean toward
the septic tank.
1. Final grading over the septic tank shall be such that a positive slope exists away from the septic
tank.

7. All H.D.P.E. tanks shall have a vertical length of 4 -inch perforated drainpipe besides the tank
extending to the bottom of the tank to above grade to monitor ground water.
S. All tanks shall be anchored when there is not enough adequate soil cover to resist buoyancy
forces in high -groundwater areas.
9. All holding tanks and lift stations shall have an audible and visual alarm inside the residence.
10. All lift stations shall be wired in compliance with the Uniform Electrical Code and all MOA
guidelines.
11. The contractor shall remove the old tank, or abandon it in compliance with the Uniform
Plumbing Code. The contractor is solely responsible for the abandonment procedure.
ABSORPTION TRENCII/DRAINFIELD 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 excavaction become smeared,
they must be raked or scratched (roughed -up) before gravel (sewer rock) placement.
1. Once the sewer rock is installed, the distribution'
installed level with the perforations
facing downward. Gravel is then to be placed over the distribution
tribution pipe to provide a minimum
of 2 inches of cover over the pipe.
1. 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 ball.
1. Monitoring tubes shall be 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.
1. Backfill over the final gravel layer must not be less than twenty-four 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.
1. All advanced technology waste water disposal systems (Advantex, Biocycle, Intermittent
Dosing Sand Filter, etc...) shall be constructed, installed, maintained and monitored per
manufacturer's specifications and MOA requirements.
MINIMUM MATERIAL SPECIFICATIONS:
1. A MOA approved septic tank manufacturer must construct any septic tank proposed for
installation.
1. The following pipe materials are MOA approved for use in septic system installations:
Type of PipesPerforate olid
Cast Iron Yes Yes
ASTM D3034 (PVC) Yes Yes
ASTM F810 (HDPE) Yes No
ASTM D2662 (ABS) Yes Yes
1. Insulation shall be at least Y' thick extruded direct burial polystyrene (Dow Chemical Company
Styrofoam HI or equal).
1. Septic tank inlets and outlets shall be fitted with watertight couplings (Caulder, Fernco, or
equal).
1. A permeable nontoxic silt barrier (Typar 3401, Miraft 140N, or equal) must be installed between
the final leachfield gravel layer and the native soil backfill.
1. All leachfield gravel (sewer rock) shall be 0S"-2.5" screened gravel with less than 37, passing
the #200 sieve. If deemed necessary, a sieve analysis should be performed.
1. When sand is being used as a filter material, its gradation specification must conform to current
MOA or DEC requirements.

INSPECTIONS:
Typically there will be 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 thep
other backfill. lacement of the sewer rock, distribution
lines, standpipes, and cleanouts, but before the placement of the silt barrier, insulation or any
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. 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 contractor's
activities.
The owner shall contract with the contractor to perform the work outlined in these specifications and
attached plans and in accordance with the attached MOA permit. All materials, components, and
construction practices shall comply with the MOA's and the State of Alaska's latest ordinances,
regulations, or policies regarding wells and septic systems. The failure of the inspecting engineer to
notice a material or construction non-compliance does not relieve the contractor of his/her
responsibility to correct such deficiency. There will be no contractual arrangement existing between
the contractor and KND Engineerin&, Inc. KND shall be the owner's representative and will inspect the
work as stated above to document the contractor's activities. Final acceptance of the contractor's work
rests with the owner and the MOA.
KND 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. KND's inspecting engineer will not be responsible for
the construction means, methods, and techniques, sequence, procedures or the safety precautions
incident to this project.
