Septic System Installation Permit
7023 Tanaina Dr., Anchorage, AK 99507
Ladies and Gentlemen:
I am writing to request a permit to upgrade the septic system for the above referenced property.
The existing system is no longer functioning adequately. A soil log, design calculations, a site
plan, design drawings and construction specifications are enclosed for your review.
Design Calcs:
No groundwater observed to a depth of 16.5 feet
below ground surface (10/14/2011 )
Soil Rating. From Testhole 10/5/2011
<1 min/in = 1.0 gal per sq.ft/day
No. of Bedrooms 3
Required Area per Bedroom: 150/1.0 =150 sq.ft.
Total area required: 150 x 3 =450 sqft
System: We are proposing a 1000 gallon septic tank, and a shallow trench absorption field.
The absorption field will be 50 feet long and 5 feet wide and contain 4 feet (500 sq.ft, effective)
of sewer rock. The existing septic tank is underneath the garage. It was installed pre-1965 and is
approximately 68 feet from the well. We propose leaving this tank in place and installing a new
tank outside of the 100 foot well radius.
Soils: A test hole was excavated on October 5th, 2011. See the attached soil logs. Ground
water was not observed. The percolation rate of the soils was less than one minute per inch. The
soils were predominately a fine grain sand with minor amounts of silt. The sand should provide
excellent treatment as the effluent percolates through the soil column.
Surface Water: No surface waters were observed within one hundred feet of the proposed
septic system.

Topography: The lot in the area of the proposed septic system upgrade is generally level. The
ground surface elevation varies by +/- 1 foot over the length of the proposed trench.
Waivers: The existing septic tank is below the garage and is less than 100 feet away from
the well. We are not making any changes to this tank and it has been approved in its current
configuration.
If you have any questions or concerns, please contact me at 279-3916.

Septic System Installation Permit
7023 Tanaina Dr., Anchorage, AK 99507
Ladies and Gentlemen:
We have applied for a permit to upgrade the septic system at the above referenced property. The
existing septic tank is located beneath the garage slab approximately 18 feet back from the
garage door and 7 feet from the foundation wall. The tank was inspected by camera on Oct. 28th,
2011 and appears to be a single compartment, vertical walled cylindrical concrete tank with a
volume of approximately 1000 gallons. No structural deficiencies were observed.
Due to the location and depth of the tank, decommissioning it would be very challenging/
intrusive. Since the tank appears to be in good condition and its presence underneath the garage
does not appear to present any structural problems we are requesting that a permit be issued to
upgrade the septic system without decommissioning the tank. A clean out is present that enables
the tank to be pumped out as required.
If you have any questions or concerns, please contact me at 279-3916.
Sincerely,
Lars S~kland, P.E.

qualified manufacture/supplier if the existing septic tank is found to be defective.
Construction shall include two 4" diameter cleanouts for pumping access.
The burial rating of the tank shall be adequate for the actual burial depth encountered.
The tank shall be level and sufficiently bedded to prevent settling of shifting of the tank.
All standpipes on the tank shall extend a minimum of 12inches above the final grade.
Tanks installed with less than 4 feet of cover shall be insulated.

contractor shall refer to the engineer for direction regarding this matter.
The tank backfill shall be graded sufficiently to ensure positive drainage away from the
tank.
All holding tank and lift stations shall have an audible and visible alarm inside the
residence being served.
All lift stations shall be wired in compliance with all MOA guidelines and the Uniform
Electrical Code. A municipal electrical permit and inspections must be obtained where
required by the MOA.

water wells. Additional separation distances must also be maintained.
The contractor shall remove or abandon the existing tank in compliance with the Uniform
Plumbing Code.
Drain field Construction:
1. The drain field shall be excavated to the dimensions outlined in the design drawings. Tf
any discrepancies are noted, contact the engineer immediately for clarification.
2. The drain field shall be installed parallel to slope contours.
3. The bottom of the drain field shall be within 2" of level. Tf the sidewalls or bottom of the
excavation become smeared, they must be raked or scarified prior to the placement of
filter sand or drain rock.

TEST PROCEDURE: WELL WAS PUMPED AT A CONSTANT RATE OF 6
GALLONS PER MINUTE WHILE THE DRAWDOWN WAS
MONITORED WITH AN ACOUSTIC PROBE. THE WELL WAS PUMPED TILL THE
DRAWDOWN STABILIZED. STATIC WATER LEVEL WAS FOUND AT 158 FEET
BELOW TOP OF CASING. WELL WAS PUMPED FOR ONE HOUR AT A CONSTANT
RATE OF 6-7 GALLONS PER MINUTE. THE WATER LEVEL DROPPED TWO FEET
DURING THIS PERIOD. A TOTAL OF 330 GALLONS WERE DRAWN.
TEST FOR COLIFORMS: WATER WAS TESTED FOR COLIFORM BACTERIA ON
JULY 25, 1986. TEST WAS NEGATIVE.
TEST RESULT:
THIS WELL MEETS THE REQUIREMENTS OF THE
MUNICIPALITY OF ANCHORAGE.
The Municipal requirement for well flow is 150 gallons of water
per bedroom per 24 hours.This well surpasses this requirement.
The assessment of the condition of this well applies only to the
conditions as of this date. The flow rate of the well may change
due to subsurface conditions that may not be observed from tile
surface, and changes in land use and other factors that may
impact the conditions of the aquifer feeding the well.

The operational life of all septic systems depends on the local

year, and the water usage of the family being served by the
system. These conditions are outside the control of the evaluator
of this septic system. We can therefore not give any estimate of
how long the system will continue to meet the operational requi-
rements of the Municipality and State.

REQULoT FOR WAIVER OF SEPARATION DISTANCES FOR CLASS C
WELL. LOT 23, TANAINA HILLS
Gentlemen;
On behalf of Mr. Max Peabody a request for a waiver of the
separation distances stated in Title 18, Alaska Administrative
Code Chapter 80.020 is hereby submitted.
The residences of Lot 23 and Lot 24 are connected to the well
located on lot 23. The water and sewer systems were constructed
on or before 1965. No original records are awailable at tile
I '
4unlcipality. An approval of the well arid septic on lot 23 was
granted by the Municipality in 1981, but it was not noted that
the well was a class C well. No well log exist for the well on
lot 23, however the depth of the well wasmeasured to be 210 feet
with a static water level at 16~..9~feet below ground.
The well log for the well on lot 20, which abut lot 23, shows
various clay strata between 26 feet and 176 feet, with water
bearing sand at 176 to 180. With this depth to water and with
more than 100 feet of impervious clay separating the ,urface
soils from the aquiver, the posibility of the ~ '
contaminating the water sourse is highly unlikely. .~,eptlc system
I recommend that your office grant the requested waiver for a
s~paration distance of 120 feet between this Class C well and the
s~ptic system.
Copies of well log and un~cioal file are included with this
request. '
Yours

Adequacy Test

Our Report #81-E-19
Dear Mr. McCourt:
As per your request, I have completed the adequacy test on the sewage
disposal system at the lot described above.
The existing system is somewhat unusual in that it consists of a septic
tank located within the subject's garage which in turn leads to
apparently 2 separate seepage pits in series. The two pits are separated
by approximately 24' and each has a 4" clean out standpipe.
After initial measurements were made, the septic tank was pumped with
approximately 1000 gallons being removed. Water was then added to the
first in the series of two pits at about 5 gpm until a total of 500 gallons
was added and the depths of each pit and septic tank were monitored at
regular intervals. (.See attached table).
The same procedure was followed the second day of the test and the levels were
monitored again on the 3rd day. Test results indicate that the second pit
did not receive the effluent at the required rate the first day but did return
within 2" of its starting level after the 2nd day of adding water. This coupled
with the fact that water never did stand or back up into the first pit indicates
to me that the system as a whole is adequate to handle the normal daily rate
of the three bedroom home.
It should be noted that the well is located within the 100 foot radial distance
from the septic tank. The first seepage pit is approximately 101 feet from
the well and the second and major absorption area is about 125 feet from the
well.
If you have any further questions, please call.
Since~ely,.,,.~ / ~
