Subject: Lake Ridge Terrace, Block 1A Lot 7A
New Septic System Design
An existing bed has failed on the subject lot. A new soil test was completed, SM soil and
groundwater at depth. The design calls for a deep trench and new septic tank. The lots to the
south are on public water and sewer. A large terraced garden slope exists at the new trench site.
Please review the wastewater system design for the single family home. I have included design
plans & specs, design guidelines, & soil tests. If there is need for additional information or
clarification please give me a call.
Thanks -Sick

Subject: HAA for Private Well & Septic System. Lot 7A, Bk 1-A, Lake Ridge Terrace S/D.
14742 East Lake Ridge Drive. Waterfront on Fire Lake.
To whom it may concern:
The subject lot has a 3 bedroom house on it which is served by a private well and septic system.
The results of the field investigation and adequacy tests are summarized as follows:
A: WELL UNDOCUMENTED: When the septic system was installed in 1969, it was noted on
the inspection report that the water source was Fire Lake. In short, there was no well at that
time. Upon my initial inspection, two wells were identified on the lot, one near the northeast lot
corner, and one near the southeast lot corner. The well at the southeast corner was not in use,
uncapped, and according to the property owner (Mr. Waner), "never really produced any water".
In addition, it was only about 86 feet from the septic tank. This well (southeast corner of lot) was
decommissioned by cutting it off 2 feet below grade, filling it with concrete, and welding a steel
cap on the top. The well at the northeast corner of the lot is active.
B. WELL CONSTRUCTION: The well was inspected by Dave Harper, Alpine Drilling, on, or
about, 7/5/97. He left a telephonic message for me on the morning of 7/7/97 indicating that the
well was cased to a depth of 38.5 feet, with perforations starting at 37 feet. He asked if I would
prepare the report, based upon his message, since he would not be able to write a report at this
time due to extenuating circumstances (death of son the previous day). Attached is an as -built
survey, dated 7/8/73 which shows the subject well, confirming that it was constructed prior to
1975. It is my understanding, in talking with Dan Roth (DHHS engineer), that wells drilled prior
to 1975 were under State regulation, which only required a casing depth of 30 feet. If this is
correct,, the subject well should be "grandfathered" in under the old regulations. Please provide
direction from your department.
C. WELL ADEQUACY TEST: The static water level on 6/16/97 was 35' BTC (Below the
top of the casing). Water was pumped from the well at a rate of 4.2 gpm for a 25 minutes (105
gallons). This caused the water level to drop 53 feet, down to the pump level (set at 88 feet). In
short, the well was "dry". The pump was then turned off at the breaker. The recovery was
monitored for 60 minutes. The results are summarized as follows:

The recovery in one hour was approximately 34.5 gallons, or .58 gallons/minute. The pump was
turned on again, until the water level was drawn down to the pump intake. This took
approximately 13 minutes, and total flow of 37.7 gallons. The recovery of the well was then
monitored over a period of 120 minutes. The results are summarized as follows:

The total volume recovered in the casing is approximate, and based on an assumption of 1.5
gallons/ft. Based upon the data, over a period of 218 minutes (38 minutes. pumping, and 180
minutes monitoring recovery) it can be seen that the recovery of the well is approximately 0.5
gallons per minute. The ability of the well toproduce at this ratefor an extendedperiod of time,
or seasonally (well production is typically lower in late winter) is uncertain. Based upon this
data it was determined that the capacity of the well meets the Municipal requirement for a 3
bedroom house (.31 gallons per minute), however, a storage system will be necessary in order to
meet peak demands
D. SEPARATION DISTANCE FROM WELL TO SEEPAGE PIT: Attached is a drawing
prepared by Alaska Water & Wastewater, which indicates that the existing seepage pit is
approximately 98.5 feet from the well. Also attached is a survey by Robert Johnson, L.S which
states that the separation distance from the crib to the well is exactly 100 feet. Given the accuracy
of the instrumentation used by the surveyor, it is reasonable to assume that his assessment is the
more accurate of the two. In reality, it is not possible to determine the actual separation distance
without exposing the gravel perimeter of the seepage pit (which would require removing the
concrete floor).
E. SEPTIC SYSTEM: The septic system was installed October of 1969 and consists of a 1350
gallon concrete septic tank, and a cement ring seepage pit. Some time later, the garage was
constructed over the seepage pit area. In June of 1997 the homeowner had Denali Pumping
locate the seepage pit using a transmitter. Once located a hole was cut in the concrete floor, and
the top of the concrete lid exposed. A 4 inch diameter hole was core drilled into the lid, and a 3
inch diameter clean-out/inspection pipe installed. The north sidewall of the septic tank was used
as part of the foundation for the addition (garage). The top of the concrete tank is flush with the
ground surface, and is uninsulated. It is my understanding that the system has functioned
adequately this way, since 1969.
Prior to starting the adequacy test (6/16/97) the seepage pit (S.P.) had 9.625 inches of liquid in
it. The septic tank had been pumped on 6/10/97 so the system had an opportunity to recover
somewhat. Water was added into the S.P. at a rate of 5.04 gpm for a total of 126 minutes (635
gallons). The liquid level rose 30.875 inches, for a total depth of 41.5 inches. The recovery was
monitored for 30 minutes, during which time the level remained virtually unchanged. Based upon
this data, it was determined that the system would need to be filled to a greater depth in order to
achieve any significant absorption. An additional 596 gallons was introduced over a period of 120
minutes. The liquid level rose from 41.5 inches to 64.625 inches (rise of 23.125 inches), which
corresponds to 25.8 gallons per inch. The recovery was monitored for 60 minutes, during which
time the level dropped 3.75 inches, indicating an absorption of 96.8 gallons. Based upon this data
the absorption rate was deemed to be adequate for a 3 bedroom house (450 gallons per day
required).
The septic tank vent (see attached photograph) and lids are caulked with mastic so there can be
no intrusion of surface water. Per Mr. Warier, the vent was installed to prevent sewer gases from
venting into the garage area. Every time the lids are removed (for tank pumping/cleaning) the
vent and lids will have to be recaulked by the homeowner.
F. SEPARATION DISTANCE FROM SEPTIC TANK TO WELL ON LOT S, BK 1-A: I
was able to locate two wells on the lot immediately to the south, Lot 8, Bk 1-A. One of the wells
is about 99 feet from the septic tank on Lot 7A. Lot 8 has a commercial type structure on it that
is being used for a mechanics shop. The lot is not served by public sewer, and does not have a
septic system. I was able to see a porta-potty in the garage. In short, the well is not used to any
significant extent. When the septic tank was installed (10/69) on Lot 7A, the required separation
distance to a private well was 50 feet, and to a class "C" well was 80 feet. In short, at the time of
construction, the septic tank was in compliance with M.O. A, and DEC regulations.
G. CLOSING: If you have any questions, please contact me at 337-6179, 244-9612, or on my
digital pager at 1-800-481-1162. Thank you for your assistance.
NOTE: The adequacy of a septic system is influenced by numerous factors, including, but not
limited to, seasonal surface water infiltration, groundwater variations, septic system
maintenance (frequency of septic tank pumping, usage of biological additives), condition of
drainpipe and pipe joints (which can be damaged by seismic activity and deteriorate with age),
type of substances deposited in septic system (cigarette butts, sanitary napkins, misc. objects),
and the amount of water being introduced on a continual basis. Consequently, the results of this
adequapy test are only valid for the specific day of the test. Furthermore, because of the limited
nature of this investigation, it is. possible that there are hidden defects which ma not have been
detected No warrantee is made regarding the future performance of this well or septic system.
The suitability of theproperty to accommodate afuture upgrade (well or septic) has not been
addressed as part of this evaluation.
