Re: New Septic Tank Permit
Legal: WILLIAMSON#2 BLOCK 2, LOT 29
The owner has requested we proceed forward to obtain a septic permit to upgrade the
aged septic tank and lift station on the subject lot. The proposed upgrade will serve the
existing 4-bedroom house.
The lot and area is served by community water and this system will not impact any of the
neighboring properties due to the lot layout. Please contact me if you have any questions.
Sincerely,

Dear Keith:
Thls is in regards to Lot 29, Block 2, Willfamson Subdivision. A copy of
the soll log ls enclosed. As you can see, there is a silt From i to i0
feet, whlch has a percolation rate of 56 minutes per 1nth. Below this ls
a silty sand. A percolation test was atter~ted in thls s11ty sand, but
according to Oennls Roe, Drilllng Supervise.c, it was a sandy r~terlal
that kept sloughing into the drlll hole so that a test could not be run.
However, the drlllers felt that slnce the soll actually lr~oroved at l0
feet, it would be safe to apply the sllt's ratlng to the silty sand.
On the permit, it was stated that a percolation test would be required in
the silty sand. Although I inspected this ,system, I dld not notice thls
on the perr~t. I was paying more attention to the drawings and
specifications, and thought the permit only had the legal, address and
permit numSer. However, slnce a drlll rig could not test the sllty sand,
the only test would be by means of a backhoe.
To perform a percolation test in the bottom of a test hole dug by a
backhoe that was 10 feet deep would be gravely dangerous. According to
OSHA, we may not climb down into any trenches or test holes that are
deeper than shoulder hel~ht, because a hole can cave in at any tlme,
burying a person. ~ly if crlbbing is built can a deep trench be entered
safely.
The soil in the test hole is silt or better. I feel that applying the
56-minute per lnch ratlng to the entire strata ~uld be qulte
appropriate.
If you would like to discuss this Further, please do not hesitate to
call.
Sincerely,
DarcyCaevens

Gentlemen:
We are submitting herewith the test boring results and our comments
regarding soil conditions encountered at the subject site. This
investigation was performed in accordance with your request of April 21,
1975, and those procedures outlined in a letter dated December 19, 1974,
by Mr. Rolf Strickland of the Greater Anchorage Area Borough Department
of Environmental Quality.
A single test hole was put down within Lots 4 and 29 for the purpose of
defining general subsurface soil conditions for the proposed sanitary
system. Excavation was accomplished with an auger type drilling rig and
the test holes ware extended to a total depth of 20 and 19 feet below
ground surface. One sample was recovered from each of the test holes and
retained for grain size analysis. The results of these samples are
enclosed. The final log prepared for the test hole has been included
in Drawing A-ol.
Ground water was not encountered in the test holes.
We appreciate being given this opportunity to be of service to you.
Should you have any questions with regard to the above, please do not
hesitate to contact us.
Very truly yours,
R & M CONSULTANTS, INC.

Subject: Adequacy Test on Existing Sanitary Sewer System; Lot 29, Block
B, Williamson Subdivision, Anchorage Alaska
Dear Mr. Pavlas:
At your request of January 26, 1978, we conducted a test on the septic
system on the above described property.
During this test the liquid level in the septic tank was monitored as
water was added to the system. The measurements are summarized in the
following table:
Liquid Level Below Top Total Gallons
Time of Standpipe Added
10:35 4.5 25
10:45 4.3 50
10:52 4.0 75
11:05 3.5 125
11:15 4.0 125
11:45 4.2 125
12:00 4.5 125
The meter used during the test was a Rockwell 5/8" standard water meter
which had previously been calibrated by R & M Consultants, Inc.
If the two bedroom residence on the property is to house four people,
the average load on the system can be expected to be 300 gallons per day
or .21 gallons per minute. During the test, the system accepted 125
gallons in 95 minutes. This indicates an average effluent acceptance
rate of approximately 1.32 gallons per minute at the time of the test.
This acceptance rate is also adequate for a 3-bedroom residence for
which the average load would be 450 gallons per day or .31 gallons per
minute.
Because the house on the lot is occupied, we assume that the leach field
was at its normal degree of saturation. We can therefore conclude that
the system is disposing of effluent at an adequate rate for a 2~bedroom
residence.
