RE: Individual Sewage Disposal System (ISDS) Report
West Bank Mesa, Filing 4, Lot 62, Garfield County, Colorado
Dear Gary:
Per your request, SGM has evaluated the design of the proposed septic system to service the
residential flows from the proposed Cain residence located on Lot 62 in Filing 4 of West Bank
Mesa.
Based upon the drawings submitted to SGM, we understand that the design of the ISDS will
be for a 4- bedroom home. The on -site soils investigation was conducted by the Garfield
County Building Department and we have been informed that the percolation rate for design
of this system is 24 mpi. The soils investigation did not identify the presence of groundwater
or bedrock within the upper eight feet of soil at the site for the disposal field.
Based upon the percolation test results and the soil observations reported, it appears that a
standard leach field system can be installed on the site. This, of course, assumes that the
setback requirements can be met in accordance to Colorado Department of Public Health &
Environment ( CDOPHE) regulations. Accordingly, we have attached a table from the CDOPHE ,
ISDS regulations which identify the required setbacks for each component of the septic
system installed.
The proposal for disposal of effluent from the septic system for this site considers the use of
a standard drywell -type construction. To briefly describe the septic system as a whole, it is
proposed to collect the effluent from the main waste line from the house in a 1250 gallon
septic tank. Please note that this 1250 gallon concrete septic tank does have alternative
installations available. These alternative installations can be considered, considering the fact
that no evidence of high groundwater is present. The alternative installations that can be
considered with this type of septic tank is that of a fiberglass septic tank, also equal to 1250
gallons. We have not provided information as to a specific manufacturer product line for the
fiberglass septic tank. Please note that the septic tank must be located at least five feet away
from the residence. In addition, the effluent line leaving the house and going to the septic
tank must be straight in alignment and straight in grade.
If it is deemed necessary that any changes in the alignment and /or grade in this main line from
June 26, 1998
Mr. Gary Belk
Page 2
the house to the septic tank is required, a cleanout will be necessary to accompany the
installation. This main line from the house must be a minimum specification ASTM 2729 PVC
pipe of minimal 4" diameter. The grade of the pipe must be at a minimum of '/ " per foot.
If it becomes necessary that the main line must cross a traveled area (i.e., a vehicular access),
we would then recommend that the pipe specification increase in strength to no longer utilize
an ASTM 2729 designation but, rather, use a Schedule 40 PVC.
To compensate for differential settling between the septic tank and the incoming and outgoing
piping, we would recommend that the piping coming into and leaving the septic tank be
sleeved in a 6" diameter cast iron pipe or Schedule 40 PVC. Once the effluent line leaves the
septic tank, it will need to proceed towards the drywell construction at a minimum of '/" per
foot grade. Again, the minimum diameter of this pipe would need to be 4" in diameter. We
would recommend that, from this point to the drywell system, location of the drywell system
and piping be coordinated such that no vehicular access is allowed over the piping or the
disposal field. Additionally, with this recommendation, we would then maintain that the
ASTM 2729 PVC piping be utilized.
For the drywell system itself, we would recommend that the system be installed in a
configuration identified on the attached sketches. The closest that the drywell excavation can
be to the residence is 25 feet. Please note that the drywell must be installed in native,
unexcavated material, not in fill.
As mentioned throughout this report, a number of attachments are included with this report.
Please find the following list which specifically identifies the attachments in order:
1. Calculations of leach field and septic system sizing.
2. Table of minimum horizontal setbacks.
3. Schematic plan view of septic system installation.
4. Drywell installation plan.
5. Drywell installation section.
Some general notes that must be mentioned regarding any septic system installation are as
follows:
1. All materials, installation practices and setback requirements shall comply with
Garfield County ISDS Regulations.
2. The drywell excavation (and gravel area) must be constructed so that the
bottom of the excavation is ± 0.1". Place the drywell in natural ground, no
portion of the drywell shall be placed in fill. Once backfilled, provide positive
drainage away from the drywell.

3. The area disturbed by construction shall be reseeded by native grasses to
prevent erosion.
4. Use risers as needed to bring the septic tank hatches (both hatches) within 6"
of finish grade.
5. Locate the septic tank such that the access to the tank can be accommodated
for future pumping (both hatches).
6. The Contractor and Owner shall take whatever measures are necessary to
ensure that (a) the sewerline and septic tank are completely water -tight to
prevent infiltration of groundwater into the system, and (b) the system is
installed to prevent freezing of the gravity sewerlines.
7. The Engineer and Garfield County Building Department shall be notified when
construction commences and be kept abreast of the construction progress so
that sufficient inspections can be performed to assure conformance with this
report.
8. It is the Contractor's responsibility to verify all locations of utilities and
setbacks that may be affected by the installation of the septic system.
Verification of all utility locations shall be made with the appropriate utility
company. Any and all easements required to be secured for the installation of
the septic system shall be obtained by the Contractor and /or Owner as they
relate to adjacent utility easements.
9. Substitution of materials (i.e., pipe, tanks, etc.) is acceptable, provided
verification and acceptance by the Engineer and the Garfield County Building
Department is made.
As you can gather from reading this report, we are leaving the specifics (i.e., exact location,
grades and elevation) of the installation of the system up to the Contractor and /or Owner.
It is important to note, however, that the location of the septic system must be provided in
the same general location of that identified in the boring logs and /or soils percolation test hole
locations. In essence, if the general location of the system is to be located on a site different
than where the percolation tests were performed, verification of the percolation rates must
be made by SGM or Garfield County prior to final installation of the drywell. If it is determined
that the information as provided is not of sufficient detail for your Contractor and /or yourself
to construct the system, please notify us immediately and we can provide a detailed
construction plan for the system. To accommodate such a detailed construction plan, SGM
would have to coordinate with yourself collection of detailed topography in the area of the
proposed septic system.
