RE: Individual Sewage Disposal (ISDS) Report
Hagemann Residence, Morsianna Mesa, Rulison, Garfield County, CO
Dear Steve:
Per your request, Schmueser Gordon Meyer has evaluated the design of the proposed septic
system to service the residential flows from the proposed Hagemann Residence located at 3959
County Road 301 in Garfield County, Colorado. Based upon conversations with yourself, we
understand that the design of the individual sewage disposal system will be designed for a three
bedroom home. We have conducted an on -site soils investigation (ie., perc test), and will uss
the results herein. We have identified an average percolation rate for this property to b 134
minutes per inch. The soils investigation did not identify the presence of ground water or
bedrock within the upper eight feet of soil at the site of the disposal field.
The sketch below describes the soil log from the profile hole.
6 " -12" DEPTH OF TOPSOIL
12 " -96" DEPTH OF POROUS,
ROCKY, CLAYEY SOIL
WITH CALICHE INTERSPERSED
A summary of the observed soil types identified that the septic system (or leach field system) is
to be installed in silty clays identified as being moist, light brown, and slightly porous. Based
upon the percolation test results and the soil observations, it appears that a standard leach field
system can be installed on this site. This, of course, assumes that setback requirements can be
met in accordance to Colorado State Health Department regulations. Accordingly, we have
attached a table from the Colorado Department of Health ISDS regulations which identify the
required setbacks for each component of the septic system installed.
The proposal for this site as far as method of disposal co nsiders the use of a standard "infiltrator"
system. This system, as proposed, will be installed in a trench -type fashion. According y, we
have attached manufacturer's product information regarding the infiltrator and the infiltrator
system installation. To briefly describe the septic sys = • e it is proposed to collect the
effluent from the main waste line from the house to . 1000 allon concrete septic t. Please
note that the septic tank must be located at least five feet away from t e re ' . . n 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 change in alignment and /or grade in this main
line from the house to the septic tank is required, a cleanout will be necessary to accompany the
installation. This main line coming from the house to the septic tank must be a minimum
specification ASTM 2729 PVC pipe of minimum 4" diameter. The grade of the pipe must be at a
minimum of '' /4" per foot. If it becomes necessary that the main line must cross a traveled area
(i.e. vehicular access), we would then recommend that the pipe specifications 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 pipin: . ��'_ : into and leaving the septic tank be sleeved
in a 6" diameter cast iron pipe or SchedulieMire Once the effluent line leaves the septic tank,
it will need to proceed towards a distribution • - or header. At the distribution box or header,
effluent would be equally split to the various infiltrator trench systems. The piping to the
infiltrator trenches will need to slope at a minimum Y4" per foot grade. Again, the minimum
diameter of this pipe would need to be that of 4 ". As an alternative to the distribution box (or
header), a separate line from the second chamber of the septic tank can be installed to each of the
separate trenches. This would allow for equal distribution of flow to each of the trenches. We
would recommend that the location of the infiltrator system and piping be coordinated such that
no vehicular access is allowed over the piping or the infiltrator system. Additionally, with this
recommendation, we would then maintain that the ASTM 2729 PVC piping be utilized.
For the disposal system itself, we would recommend that three infiltrator trenches be installed.
We have attached our calculations which define the length of infiltrator trench necessary as well
as the number of infiltrator units necessary per trench. The closest spacing that the infiltrator
units can be installed is 10 feet on center. The infiltrator units must be placed in a flat trench.
We have attached a sketch which identifies the typical piping requirements to equally distribute
flow to each of the infiltrator trenches. As previously discussed, we have attached the
manufacturer's literature regarding the infiltrator system. With that manufacturer's literature is a
detailed list of instructions regarding the septic system installation. You will note that the
backfill required over an infiltrator trench is that of native backfill. This native backfill is
acceptable for fill over the trenches as long as 6" and larger rock is not allowed in the backfill.
The minimum requirement of 12" of cover over the infiltrator system is also identified. Please
note that the infiltrator must be installed in an excavated trench and not in fill.
As mentioned throughout this report, a number of attachments are included with this report.
Please find the following list which identifies specifically the attachments in order:
1. Calculation of leach field and septic system sizing.
SCHMUESER GORDON MEYER, INC.
2. Table of minimum horizontal setbacks.
3. Percolation test results.
5. Schematic plan view of' septic system installation.
6. Sketch of the standard infiltrator chamber.
7. Infiltrator manufacturer's literature.
8. Septic system installation instructions (from Infiltrator manufacturer literature).
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 Individual Sewage Disposal System Regulations.
2. The infiltrator trench shall be constructed so that the bottom level of the trench is
± 0.1 inches. Place trench in natural ground, no portion of the trench shall be
placed in fill. Once backfilled, provide positive drainage way from the trenches.
3. The area disturbed by construction shall be reseeded by native grasses to prevent
erosion.
4. Use risers as needed to bring septic tank access hatches within 6" of finish grade.
5. Locate septic tank such that the access to the tanks can be accommodated for
future pumping.
6. The contractor and owner shall take whatever measures are necessary to assure
that (a) the septic tank and sewerlines 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 Department shall be notified when construction
commences and 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 insta llation of the septic system. Verification of all
utility locations shall be made with the appropriate utility company.
SCHMUESER GORDON MEYER, INC.
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 to yourself. It is important to note,
however, that the location of the septic system must be provided in the same general location of
that tested with the soil profile hole and percolation testing. In essence, if the septic system is
located on a site different than where the percolation test was taken, verification of the perc rates
must be made by SGM prior to final installation of the leach field. If it is determined that the
information as provided is not of sufficient detail for 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. Aside from the
comments just made, I hope this information is of sufficient detail to accommodate your needs in
installing this septic system. If you have any questions or comments, please don't hesitate to call.
Sincerely,
onvon
