Yes we can make mid trench entrance with the -2.5'. We will make it 25L & 2.5' max depth and note

Can you just have the pipe enter the trench mid length? Do you have the fall for that? Then you can
leave it at 25' long.
2.5' depth of rock is good because it maintains 2.4' of vertical separation from September
groundwater reading. Just include this info on the record drawings.

Subject: Re: Rainbow Creek Lot 1
Sorry about that, but a reduced application rate of 5GPD/SF was used and a 6GPD/SF
application could be used and be at 20' total length if you want, we just proposed a 5'
longer tread and would still propose that to be installed. The 25' length is close to the 20',
r� ���.. ✓t iY r �
but we can make the application 6 and shorten. It has been done before with just a bit
more length. The 1.5' total depth is ok, but we could make it 2.5' and that is why it was
proposed. 2.5' total depth - 5.9' September reading is 3.4' a current separation or 2.4' from
the assumed high seasonal. Since installation is currently in process, we cannot wait for
an October reading, but believe it will be about the same as monitored.
This system will be gravity fed. So we can shorten to 20' using the 6 rating or keep the 25' 5
rating AND we can keep it at -1.5' or -2.5'. Either way - 251 - 2.5' or 20' L - 1.5'. Kinda
spitting hairs here, but would think the 251 x -2.5' would be best. What would the MOA
want?
Be Safe, Thanks!

July 8 groundwater 5.6'
Aug groundwater 5.8'
September 5.9' adjusted would be 4.9'
If you install bottom of rock at 2.5 below grade that would be 2.4' separation from
the adjusted groundwater reading in September. In order to have reduced vertical
separation you either need to use pressure distribution or segments not exceeding
20' in length. 15.65.355H. Which one will you do?
At time of inspection report submittal add new groundwater readings to your test
hole.

Planning on installing field to a max depth of -2.5' from grade with a 3.4'
separation to monitored groundwater in September per below. OK? FYI tank
hole was dry today too.

Curtis,
Per our permit letter dated 7/30/24, we ascertain that the early
groundwater readings on July 8 are conducive to a June reading
or 3' separation to observed groundwater and do not believe
these levels will fluctuate. We monitored ground water in
August on 8/17/24 at 5.8'& again today in September on
9/3/24 at 5.9'. Given this, we respectfully request that the
bottom of the proposed field be permitted to be installed at -
2.5' from grade and 3.4' from this recent September
groundwater level for this Advantex CAT III system. We
attached the permitted design for your use - please let us
know.

RE: SEPTIC SYSTEM UPGRADE PERMIT
LEGAL: RAINBOW CREEK LOT 1
The property owner has requested we obtain a permit to upgrade the
undocumented failed septic system (tank & field) of the above referenced lot. We
propose to install a shallow trench with an Advantex system to serve the existing 4 -
bedroom (3BR house & 1BR ADU) system per the attached design. The design is
based on the recent test hole conducted on June 27, 2024. Groundwater was
observed at 7’ during excavation and 5.6’ during monitoring of this test hole.
The absorption field is to be installed on slopes of 23-28% with no downhill slopes
greater than 46%. The downhill side will not be disturbed or developed and is the
Seward Highway ROW with heavy vegetation and a few hundred feet from the
actual highway. There was no evidence of any daylighting from the existing
conventional - undocumented trench. Additional cover will be placed over and
downhill of the proposed trench of the excavated / impacted area. The groundwater
was at 5.6' on July 8, 2024, and believe with the heavy and late snowpack melt of
2023-24 the readying is more conducive to a June reading.
As you know 15.65 code allows 2' separation to groundwater for CAT III and we
have maintained 4' separations and will with sand as needed. Although one would
wish to monitor groundwater in October or May, the groundwater levels will be
verified again. We maintain that site characteristics and current conditions that this
5.6' will NOT most likely rise and is the high seasonal groundwater level. If these
levels have not risen, we request that the proximity to a June reading be used with
an additional total depth of 1' or 3' to groundwater if so deemed.

The slopes are approximately 23-28% at the proposed upgrade location with 30-
40% down slopes. The lot and area are served by private water with no known
private wells within 50’ of the proposed septic system. Based on visual
observations and review of available information, the design will not impact any of
the neighboring properties. Please contact us if you have any questions.

G. CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER
As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based
on procedures outlined in the Certificate of On-Site Systems Approval Guidelines, indicates that the on-site water
supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes,
ordinances, and regulations in effect at the time of installation, unless noted otherwise.

Engineer’s Printed Name CURTIS HUFFMAN, PE Date 03/10/2025
Comments: This investigation was completed in compliance with MOA guidelines, regulations,
and best industry practices / methods. The assessment of the condition of the well and septic
applies only to the conditions as of the day tested. The flow and absorption rates may change
due to subsurface conditions that may not be observed from the surface, changes in land use,
local soil characteristics, groundwater levels that may fluctuate during the year, quality of
construction (workmanship & materials), the water usage of the family being served by the
system and maintenance. The operational life of all well and septic systems are subject to
these various and dynamic characteristics and are outside the control of the evaluator of the
well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory
for current or future occupants or guarantee that no unseen encroachments, deficiencies or
discrepancies exist can be given by First Water Consulting &
