Dear Iv~. Anderson:
Tt~s is ia response to the submittal received for a Duplex within the IWunicipali~ of Anchorage
on Auffast 20, 2004. Your engineering plans indicate that the proposed onsite w.~stewater system
will serve a 6 bedroom duplex, lm your submittal, you requested the Department to review your

Septic System Construction and Certification
Dear Lex:
On May 19, 2005, a new absorption system composed of a 40' long x 3' wide x 10'
effective depth absorption trench was installed on the subject lot to~lispose of the
septic effluent from the six-bedroom duplex. In addition, a new 2,000-gallon septic tank
was installed to collect and treat the sewage generated in the house. All work was
completed in conformance with standards set by the State of Alaska Department of
Environmental Conservation and 18AAC 72.
The lot is served by a public water system, which is currently in compliance with ADEC
regulations.
Attached is a copy of the State of Alaska Department of Environmental Conservation

Dear Mr. Willis:
An On -Site Water/Wastewater Permit, number SW030475, issued by this office for a single-family
system, will expire on November 11, 2004. The permit was valid for 365 calendar days.
If this was a well permit and the well has been drilled, a well log must be sent to this office for
documentation of the installation and to close the permit.
If this permit was for a wastewater disposal system, an original as -built inspection report must be sent to
this office for review, approval and documentation. This as -built inspection report must be signed by
the licensed Professional Engineer who inspected the installation of the system. As -built inspection
reports are required to be submitted within 30 days of the completion of the system.
If no system was installed under this permit, and you are still planning to install a well or wastewater
disposal system, a new permit must be obtained from this office. A new permit for a second year may
be issued for a fee of $115.00 if the renewal application is received on or before the expiration date of
the original permit.
When applying for a new permit, the fees are: $460.00 for a wastewater permit and $175.00 for a well
permit.

Dear Sirs:
& A.NALY56
14530 ECHO ST.
ANCHORAGE, ALASKA 99516
The purpose of this letter is to provide the required design narrative in support of our application for
a permit to construct wastewater disposal facilities on Lot 6 of Thibodeau S/D, located at 2800
Kimberlie Court. Soils logs, perc test results, a site plan, design drawings and specifications are
enclosed for your review.
The proposed system will be constructed in the vicinity of test hole # 1. As can be seen from the soil
log, the native material below 9 feet is a clean sand with a measured perc rate of less than 1 minute per
inch. Despite the rapid perc rate, because the native material is sand, no additional filter sand should be
required. Using the soil application rate of 1.2 gpd/sq. ft. specified in the wastewater ordinance, this 3 -
bedroom residence requires a total absorption area of (3x150)/1.2 = 375 square feet. The proposed 35 -
foot long trench design has 420 square feet of absorption area below the 9 foot level. Because of the
extremely limited available area on the lot for replacement systems, we have elected to fill the trench
excavation up to a depth of 3.5 feet below ground level in order to take advantage of as much of the
shallow gravelly sand stratum as is possible without a lift station.
The topography of the lot in the area of proposed construction is generally level. We have
designated a replacement site in the northwest corner of the lot, which will involve issuance of a lot line
waiver at such time as it may be needed. Since the adjoining property is either a street right-of-way or a
lot served by public sewer, there should be no problem with issuing the needed waiver.
The proposed project will have no significant impact on present or future water supply and
wastewater disposal systems serving adjacent properties, nor will it have any significant impact on
reserved space -surface and subsurface, or on drainage.
Please give me a call at 345-1355 if you have any questions on this submittal.
Sincerely,
Ted Moore, P.E.

deviations from these drawings may be allowed or required by the engineer conducting the inspections.
All construction procedures and material specifications shall conform to Municipal and State
requirements. All separation distances shall be in conformance with Municipal requirements, unless
specifically waived.
1.3 The contractor shall be responsible to obtain any necessary utility locates, and to work around
any buried utilities.
1.4 The contractor shall provide adequate cover material and rough grading over all system
components to ensure that proper drainage is achieved after settlement and that there are no residual
depressions. Insofar as possible the contractor shall minimize damage to trees and existing lawn areas.
1.5 Unless specifically agreed otherwise, the homeowner shall be responsible for finish grading

2.2 All pipe connections to the tank shall be equipped with waterproof mechanical couplings. The
waste line from the residence to the septic tank shall have a minimum slope of 1/4"' per foot, and the
waste line between the tank and the soil absorption system shall have a minimum slope of 1/8" per foot.
A cleanout shall be installed 1 - 4 feet from the building foundation, and a double cleanout shall be
installed within 5 feet downstream of the septic tank.
3.0 Soil absorption system:
3.1 The soil absorption system shall be constructed by excavating a 2 -foot wide trench to a depth of
15 feet below ground level. The trench shall be carefully positioned so as to maintain the required
10 -foot separation from both the west lot line and the building foundation.
3.2 The bottom of the excavation shall be level. Any compacted or smeared surfaces shall be raked
to allow proper infiltration.
3.3 A total of 12.0 feet of approved sewer gravel shall be placed in the bottom of the excavation
with the perforated distribution pipes laid level such that the pipe inverts are no less than 11.5 feet above
the bottom of the sewer gravel. Sewer gravel shall be 0.5" - 2.5" screened gravel.
3.4 Monitor tubes and cleanout pipes shall be of 4" diameter and installed in the locations shown on
the design drawings. The portion of the monitor tube extending through the sewer gravel shall be
perforated.
3.5 Approved filter fabric shall be placed over the entire top surface of the sewer gravel. A
minimum of 2 feet of soil cover is to be placed over the filter fabric. If the soil cover thickness is less
than 3 feet, two inches of rigid, burial type insulation is to be placed over the entire top surface of the
gravel, in addition to the filter fabric.
3.6 The top surface of the cover material shall be raised a minimum of 6 inches higher than the
surrounding terrain to allow for subsequent settlement, and shall be graded to smooth contours. Fill
slopes shall be no steeper than 3:1.
3.7 Unless specifically agreed otherwise the homeowner shall be responsible for arranging to have
the site finish graded after the backfill material has stabilized, and for placement of adequate topsoil and
seed to promote rapid revegetation of all areas disturbed by the construction.
4.0 Inspections:
4.1 A total of 4 engineering inspections will be required during the course of the project: (1) initial
stakeout with the contractor to establish the location of the system and to discuss the plans,
specifications and construction procedures, (2) after the native material has been excavated to expose the
infiltrative surface to ensure that it is level and at the right elevation, and conforms with the soil test
information, (3) after the sewer gravel is in place and the distribution pipes have been laid and connected
up to the septic tank, but prior to placement of insulation or filter fabric, and (4) after rough backfill and
grading is complete. The septic tank requires one inspection after it is set level and the piping
connected, but prior to backfill. This inspection may be incorporated with any of the above inspections.
4.2 The installer shall coordinate the timing of the inspections with the engineer sufficiently far in
advance to ensure the availability of the engineer.
