Re: Septic permit

To Whom it may concern:
This is a request for a septic permit on the above referenced lot. A single test hole
was excavated and found poorly graded gravel (GP) mixed with sand (SP) to the
bottom of the hole at 16 feet. No water was observed during excavation or after the
7-day monitoring period. The perc rate was recorded at 3 minutes per inch. A deep
trench has been design see the site plan. An existing well secondary well will be
decommissioned also per the On-site code.
This new septic system will not impact any of the surrounding neighbors, due to the
large lot size.
Sincerely

Re: Adequacy Test for Existing Septic System on Lot 3, Block 5,
Prospect Heights Subdivision, Addition No. 1.
Dear Mr. Nibert:
At your request our office conducted a percolation adequacy
test on your existing septic system at the above-referenced
location during the period March 21 to 23, 1979. You reported
that your septic system consists of a 1000-gallon septic tank
and a log crib seepage pit.
The septic tank and seepage pit had been pumped approximately
10 days prior to the percolation test. Since the 3-bedroom
house had been occupied up to the time of the test, a normal
degree of saturation within the leach field is assumed.
In accordance with the Anchorage Municipal Code, Chapter 15.65,
Waste Water Disposal Regulations, any on-site sewage disposal
system "shall have adequate capacity to properly dispose of the
maximum daily sewage flow." The maximum daily flow is computed
at 75 gallons per capita-day (gcpd). Since "the population of
dwellings shall be estimated at two persons per sleeping room,"
the maximum daily sewage flow for your 3-bedroom house is 450
gallons per day (gpd).
To test the soil absorption capacity and the surge capability of
your system, 110 percent of the maximum daily flow or 495 gallons
of clear water was added in 50-gallon increments to the seepage
pit. The water was obtained from your on-site private well at
its maximum sustained rate of about 3 gallons per minute. The
liquid levels were monitored closely to detect any backup in
the septic system.
The attached table of Test Data represents the depths of
liquid in the septic tank and seepage pit, and the quantities
of water added. The septic tank was determined to be 9.7 feet
deep i(~bottom of tank to ground surface) with an initial depth
of 5.2 feet in the hank. The seepage pit was found to be
9.7 feet deep with an initial depth of 4.3 feet. Ground
elevation at the septic tank standpipe is approximately 1.4
feet higher than at the seepage pit standpipe.
Mr. Ray Nibert
March 23, 1979
Page -2-
The table of Test Data shows that the liquid level in the
seepage pit at the beginning of testing on Day 2 fell to 0.5
feet below its initial static level on Day 1, during a
recovery period of 16 hours. On Day 3, the level had fallen
to 0.5 feet below its static level on Day 2, during a
recovery period of 22 hours. The liquid level in the seepage
pit at its highest level during the test (6.3 feet) was
approximately level with that in the septic tank. No rise
was detected in the liquid level in the septic tank, however.
Based on two days of testing, a percolation rate for your
existing septic system of approximately 500 gpd is indicated.
Since an on-site sewage disposal system for a 3-bedroom
dwelling must be capable of disposing of 450 gallons of sewage
per day, your septic system appears to be functioning satis-
factorily at this time.
Many factors affect the operation of a soil absorption type
of sewage disposal system. Soil type, groundwater depth, age
and history of maintenance of the system, and types of waste
are a few. This test has been performed in an attempt to
estimate the actual soil absorption capabilities of your
septic system under normal useage by considering the degree of
saturation of the leach field and surge loads that might be
imposed on the system. This test can only evaluate apparent
performance at a given point in time, and cannot determine
either the condition of the leach field, seepage pit or other
components of the septic system, or the depth of the water
table.
We appreciate the opportunity given to perform.this adequacy
test. If you have any questions regarding this test, please
contact this office.
Very truly yours,
