Septic system design
Dear On-Site Services Engineer:
The owner of the above lot has a septic system that is nearing its end of useful life. We are
submitting this permit application for the construction of a new septic system. The attached site
plan identifies the location of the home as well as the existing and proposed septic locations. No
conflicts exist between this proposed system and any other well or septic system, whether on this
lot or adjacent lots.
The ground surface on the lot slopes down toward the north of the lot at grades around 30-40%,
but near the proposed septic system location slopes are mild. The steeper slopes, greater than 25%,
start more than 50 feet downslope from the trench, and the design also meets the criteria for
trenches built on steep slopes. Contours are shown on the site plan showing the grade and direction
of flow. Stormwater drainage will not impact this septic system. The new trench will be
constructed parallel to the slope as much as possible.
Wells on this and adjacent lots are shown. The new system will be a minimum of 100’ from all
wells and surface water, and more than 5’ away from the septic tank. The proposed trench is
located more than 14’ away from the existing trench.
Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design
is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
Benjamin Schiller, PE

Subsurface Investigation for Feasibility for
On-Site Sewage Disposal Systems
I,ots 1~, ~2 and 16, Block 2, Silvercrest Subdivision
and Lot ~, Block 1, SST Subdivision
Dear Hr. Stephens:
As requested we performed a subsurface investigation on the
four above referenced lots to determine their suitability
for placement for on-site sewage disposal systems. Thr~ee
test ho]es were placed on April 12 and 13, 1978. The holes
were drilled by Denali Drilling, Inc. The test hole's were
logged and the drilling supervised by Mr. O.M. Hatch, senior
technician/geologist with Alaska Testlab.
~ ~ holes are located <)n the adjacent figures !tl and ~;2.
The test ho]_e logs are included as Table A. It may prove
helpful in :i_nterpreting the data on the test holes logs to
review the standard explanatory informa{ion contained on
Sheets 1-3.
Once the test holes were drilled, they were cased with
s~otted p].astic pipe. About a week later the test holes
were checked for ground water intrusion into the h6les.
None had occurred. All three of the test holes were dry.
'Pl'~en on April. 25, 1978, the -test holes were filled with
water and left over night to saturat6d, A percolation test
was then performed the next. day, April 26, 1978, by refilling
-the holes and monitoring the rate at which the water fell. in
the holes at 10 minute interva].s fo].- a period of one hour.
The perco].ation rates based on this testing are as follows:
Lots 11 and 12, Block 2, Silvercrest --- 10 minutes/inch.
Lot 16, Block 2, Si].vercrcst Su};division -.- 5.7 minutes/inch.
Lot 1, Block 1, SST Stlbdivision -- 2 minutes/inch.
Mr. Mike Stephen
April 28, 1978
Page 2
We would caution the use of a percolation rate as fast as 2
minutes/inch in Lot 1, Block 1, SST Subdivision. It is our
experience that due to the clogging action of sewage effluent
that a more conservative design value be used in silty sands
and silts. They that have a tendency to clog. We would
reco~mnend a design value of 5 minutes/inch.
We hope this is sufficient for your present needs. If we
can be of further service or offer any clarification of any
data presented here, please do not hesitate to contact us.
Very sincerely,
ALASKA TESTLAB

TEST RESULT: THIS SYSTEM MEETS THE CODE REQUIREMENTS OF
THE MUNICIPALITY OF ANCHORAGE.
The operational life of all septic systems depends on the local
soil conditions, groundwater levels that may fluctuate during the
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.

Dear Mrs. Graham:
On May 4, 1983 a well flow test was accomplished with a adequacy test at
Silvercrest Subdivision Lot 11 Block 2.
The well flow test started at 9:32 with static water level at 93' and
was run until 10:25. This was a total of 53 minutes at which time the
well stopped pumping. In this time the static level of water in the
casing had dropped from 93 feet to 289 feet which is the shut off point
for the pump. There was a total of 279 gallons of water used in this
time.
Static water level rise was recorded, the recovery rate indicates that
the well recovered at 32 gallons per hour the first hour and decrease
with time. It is estimated that if would take 10 hours for the well to
recover back to its original level.
A conservative estimate is that this well could produce 700 gallons per
day. However sustain water use as lawn watering, or several faucets
being used at the same time could draw the well do~ sooner that 50
minutes.
Normal water usage for a 3 bedroom house is 450 gallons per day with a
peak useage of 625 gallons per day. These figures are just below the
700 gallon per day we have estimated to be the output of the well. Note
this well is marginal to satisfactory. However, with normal water
useage and not overloading the system the well should be sufficient for
a 3 bedroom house.
Sincerely,
Civil Engineer
