Septic system design
Dear On -Site Services Engineer:
The owner of the above lot has abandoned his existing undocumented septic system, so we are
submitting this permit application for the construction of a new system. The attached site plan
identifies the location of the home as well as the proposed septic location.
The ground surface on the lot is generally flat. There are no slopes greater than 25%. Due to soil
and groundwater restrictions, the proposed will be a Cat III Advantex system. All pipes that are
part of the old system that are no longer in use will be removed. While doing some ground work
the old septic tanks were found, and they will be filled with rock and abandoned in place.
During the excavation of the test hole, groundwater came up too fast for us to do a perk test on the
soils underlying the upper fill. For that reason, we took a sample of the soil to the lab for an
analysis, which is attached. The soils were classified as GP -GM, "Poorly -graded gravel w/ silt and
sand". 48% of the soil was gravel, and 45% was sand, with less than 6% passing as silt. We would
anticipate this soil to have a percolation rate of less than 5 min/in. However, we have designed this
with a conservative perk rate of 30 min/in. As there is no way to percolate these soils, we ask that
this conservative rate be accepted in lieu of a stamped perk test.
Wells on this and adjacent lots are shown. No conflicts exist between this proposed system and
any other well or septic system, whether on this lot or adjacent lots. The new system will be a
minimum of 50' from all wells and surface water, and more than 5' away from the septic tank.
Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design
is followed, there will be no adverse impacts to adjacent properties.
Sincerely,
y.�

Ref: Proposed Septic System for T12N, R3W, Sec4, Lot 16, M150' of W198',
To whom it may concern:
The existing 3 bedroom house is served by a private well mid septic system. The existing septic system is undocumented and in
groundwater. Because of restrictive site/soil conditions, we are proposing to install a CAT II1 Quanics Aerocell System and 5-
wide trench type drainfield using structural fill (MOA sand). We believe this to be the onIy I~asible option for the property.
One test hole was excavated on the properly. The drainfie[d will be designed around the 30 foot radius of this test hole.
Comments regarding the design are summarized as follows:
1. SOILS - REQUEST TO USE ERS - JUSTIFICAST1ON FOR USING ERS: Due to the Pact that a percolation test could
not be performed (bench was filled with groundwater) a sieve analysis (see attached) was performed on the receiving soil mid
was classified as SP-SM. Only 10.4% of the soil passed the #200 sieve, resulting in the dual soil classification. Approxhnately
90% of'the soil is coarse grained (sand and gravel). According to the USDA "textural triangle", the subject soil is classified as a
"loamy sand". The percolation rate associaled with "loamy sm~d' is 5-15 minutes per inch (see attached chart). AIso attached is
Table 5 from the ADEC certified installers manual, which shows the soil percolation rate for various soil types. Based upon
Table 5, SM soil typically percolates in the range of I0-45 minutes per inch; therefore, it is reasonable to assume that the SP-SM
soil will percolate at less than 30 minutes per inch. For a CAT III treatment system discharging to 30 mimtte/inch soils, the
allowable application rate is 4.0 gpd/Pt2. For this design, a conservative soil application rate of 3.0 gpd/~2 is proposed, which will
accommodate soils percolating as slow as 45 minutes/inch. The existing conventional drainfield (encroaching upon groundwater)
is located roughly 50 feet away fi'om Ihe proposed ERS system and it has been functioning lbr many years. In short, there is
sound engineering.justification fbr allowing an ERS system to be installed on this property.
2. TRENCH DESIGN: See attached design drawing for drainfield specifications
3. SURFACE WATERS: The new septic system will be located at least 100 feet away fi-om a nearby stream (see site plan).
4. TOPOGRAPHY: The topography tbroughout the area is generally flat.
5. LOT LINE WAIVER: The proposed drainfield is located approximately 6 feet fi-om the west property line. We are
requesting your department issue a 6 foot waiver to the lot line. There are no other encroachment concerns due to Spruce Street
running along the west property line.
We are unaware,~of any adverse impacts this installation would have on adjacent wells or septic systems. [f you have any
