Ref: Proposed Septic System for Lots 9A, Schumacher Subdivision
To whom it may concern:
The existing 4 bedroom house is served by a private well and septic system. The septic system is
completely surcharged and needs to be upgraded. A test hole was excavated in the area of the
proposed new drainfield. The septic system will be designed around the 30 foot radius of this test
hole. We are proposing that a 1250 gallon septic tank and two 5-wide trench type drainfield be
installed. Comments regarding the design are summarized as follows:
I. SOILS: See the attached logs which shows the soil classifications, groundwater monitoring,
and the percolation test results. It is our opinion that due to the overall appearance of the soils, an
application rate of 1.0 gallons/day/tis should be used.
2. TRENCH DESIGN:
a. Percolation Rate: <1 and 7.5 minutes/inch
. b. Allowable Application Rate: 1.0 gallons/day/ft:
c. Number ofBedrooms: 4
d. Design Flow: 600+ gallons per day
e. Minimum Absorption Area: 600 ft1
f. Total Depth: 7.5 feet (max.)
g. Effective Depth: 4
h. Width: 5.0 feet
i. Minimum Length: 60 feet long (2 x 30 feet)
j Effective absorption area = 600 ft~
k. Reduction Factor: 0.5
3. SURFACE WATERS: There is no surface water within 100 feet of the proposed septic
system.

Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: akwwc.com
4. TOPOGRAPHY: As can be seen on the attached topography site plan, the proposed
drainfields are to be installed on the top of a knoll. The slopes around the knoll vary between
3040% for a very short distance and then taper off to less than 25 percent. The slope from the
invert of the drainpipe to any point along the ground surface at least 35 feet away will be less
than 25%. We are requesting that the separation distance to a slope greater than 25% be waived
from 50 feet down to 35 feet. Based upon the porosity of the soil it is reasonable to assume that
effluent in the drainfield will migrate downward rapidly and have minimal lateral migration. In
short, it is my opinion that there is minimal risk in granting this waiver.
We are unaware of any adverse impacts this installation would have on adjacent wells or septic
systems. If you have any questions, please contact us at 337-6179. Thank you for your
assistance.
~Sincere~
'.E., M.S.
NOTE: Attached is a site plan drawing, a design drawing, a topography site plan, a soils log,
and a 7 page construction specification letter which are all part of the design package for this
septic system.
