Subsurface lnvestigation and Onsite Wastewater Treatment System Design
1-Bedroom Accessory Dwelling Unit (ADU)
291 CR 119
Garfield County, Colorado
Todd,
CBO lnc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OWTS) design for the subject residence^ The 10.17S-acre property is located outside of Glenwood
Springs, in an area where OWTSs and wells are necessary.
Legal Description: Section: 30 Township: 6 Range: 88 Subdivision: CHRISTELEIT SUB AMD Lot: A
10.175 ACRES
Parcel lD: 2187-302-01 -001
SITE CONDITIONS
The property is cunently developed with a 4-bedroom residence, constructed in 1992. This residence is
served by a separate OWTS that is not addressed in this design. A 1-bedroom Accessory Dwelling Unit
(ADU) is proposed and will be served by the OWTS described in this design.
The ADU will be served by a private well on the property. The well is located to the west of the proposed
ADU" The well is located greater than S0-feet from the proposed septic tank and greater than 100-feet
from the proposed soil treatment area (STA).
The property slopes to the north and northeast towards the County Road. The proposed STA location
has an approximate 10% slope and is vegetated with sage and native grasses.
There should be no traffic or staging of material over the future STA site to avoid compaction of soils
prior to construction of the STA.
SUBSURFACE
The subsurface was investigated on July 8,2024 by digging two soil profile test pit excavations (Test Pits). A
visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.l
The materials encountered in Test Pit #1 consisted of dark brown loamy topsoil to 3.0-feet, underlain by
dense, whitish calcareous clay matrix to a maximum depth explored of 4.0-feet where practical digging
refusalwas encountered on a large boulder. No bedrock or groundwaterwas encountered.
I Carla Ostberg holds a Certificate of Attendance and Examination from the CPOWVisual and Tactile
Evaluation of Soils Training.
Page2
The materials encountered in Test Pit #2 consisted of dark brown loamy topsoil to 18-inches, underlain by
whitish calcareous clay matrix to a maximum depth explored of 7.0-feet. No bedrock or groundwater was
encountered.
A sample of the soil was taken from Test Pit #1 at 3-feet below grade. Soil structure grade was
moderate. The soilformed a ball and a ribbon less approximately 1-inch in length before breaking. Soil
structure shape was blocky and consistence was friable. Soil texture was more smooth than gritty.
We have researched soils in the area through USGS Web Soil Survey. The report is enclosed. The area of
the proposed STA is identified by map unit symbols 19 and 85. The map unit names are Cochetopa-
Antrobus association, 25 to 50% slopes, and Morval Loam, 6to25o/o slopes.
Both the loamy topsoil and calcareous clay matrix are consistent with Soil Type 2 with moderate structure
grade. A long-term acceptance rate (LTAR) of 0.6 gallons per square foot will be used to design
the STA.

Desiqn Calculations:
Average Design Flow = 75 GPD x 2 people/bedroom x 2 Bedrooms = 300 GPD
LTAR = 0.6 GPD/SF
300 GPD / 0.6 GPD/SF = 500 SF x 1,2 (gravity, bed) x 0.7 (chambers) - 420 SF
Although the proposed ADU willhave only 1-bedroom, the OWTS design is based on 2-bedrooms2. An
average daily wastewater flow of 300 GPD will be used.
For the purposes of this OWTS design, Benchmark Elevation has been established as 100' (Finished
Floor). GBO lnc. should be notified of any discrepancies or problems with grade elevations of proposed
components during installation of the OWTS.
*Elevations are based upon standard OWTS installation practices. Component elevations may change during
installation due to site conditions. Minimum grade refers to piping between components.
The 4-inch SDR-35 sewer line exiting the ADU must have a double-sweep clean out and a minimum 2%
grade to the septic tank.
The system installation must include a 100O-gallon, two-compartment lnfiltrator@ poly septic tank with an
Orenco@ Biotube effluent filter on the outlet tee. Any state-approved poly or concrete septic tank may be
substituted. Risers must bring the manhole lids to grade for access. lf more than one riser is added to
the septic tank, an extension handle must be installed on the effluent filter.
A 4-inch diameter SDR-35 level manifold must be installed to connect each row of the chamber bed. The
chamber bed will consist of 3 rows of 12 'Quick 4' lnfiltratol@ chambers for a total of 36 chambers and
432 square feet of infiltrative area. lnspection ports must be installed at each corner of the bed. Ports
may be cut to grade and placed in sprinkler boxes for access.
COMPONENT SPECIFICATIONS
The component manufacturers are typical of applications used by contractors and engineers in this area.
CBO lnc. must approve alternative components prior to installation of the OWTS. Requests must
be submitted, in writing, to our office for approval prior to installation. Component technical data
sheets are available upon request.

Construction must be according to the jurisdiction's adopted On-Site Wastewater Treatment System
Regulations, the OWTS Permit, and this design.
PERMIT APPLICATION INSTRUCTIONS
An OWTS Permit Application must be submitted to Garfield County Environmental Health Department
https://www.qarfield-countv.com/environmental-health/filesqcco/sites/16/OWTS-Application-Comolete-
Packet-Dec.-2019.pdf. lf the OWTS Permit Application will be submitted with a Building Permit
Application, it should be submitted directly to Garfield County Building Department.
Allquestions regarding permit submission can be directed to Garfield County Environmental Health
Department, 970-945-6614 x81 50.
INSTALLATION CONTRACTOR
CBO lnc. expects that the installer be experienced and qualified to perform the scope of work outlined in this
design. The installer must review this design thoroughly and coordinate with our office in advance of
installation. Any additionalconditions in this design or county permit must be completed and documented
prior to final approval of the OWTS installation. Communication between the installer and this office is
expected throughout the installation.
INSTALLATION OBSERVATIONS
CBO lnc, must view the OWTS during construction. The OWTS observation should be performed before
backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing
siphons, and other plumbing, as applicable, must also be observed. CBO lnc. should be notified 48 hours
in advance to observe the installation.
ln an effort to improve the accuracy of the record drawing, we request that the installer provide a
sketch of the installation, including path of the sewer lines, water line installation (if applicable),
septic tank location, STA location, and measurements from building comers or another fixed
objects on the property. This sketch is most easily provided on Sheet W2.0 of the OWTS Design
Packet. Photographs of the installation and final cover are also requested to supplement our installation
documentation.
REVEGETATION REQUIREMENTS
An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire
disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing
characteristics (but without taproots), provides a maximum transpiration rate, and competes well with
successional species. No trees or shrubs, or any vegetation requiring regular irrigation shall be placed over
the STA. Until vegetation is reestablished, erosion and sediment control measures shall be implemented
and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation
cover.
OPERATION INFORMATION AND MAINTENANCE
The property owner shall be responsible for the operation and maintenance of each OWTS servicing the
property. The property owner is responsible for maintaining service contracts for manufactured units,
alternating STAs, and any other components needing maintenance.
Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials
should be placed on the backfilled STA. Machines with tracks (not wheels) should be used during
Page 6
construction of the STA for better weight distribution. Livestock should not graze on the STA. Plumbing
fixtures should be checked to ensure that no additionalwater is being discharged to OWTS. For example, a
running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA.
lf an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned
annually, or as needed. lf the OWTS consists of a pressurized pump system, we recommend the laterals be
flushed annually, or as needed.
The homeowner should pump the septic tank every two years, or as needed gauged by measurement of
solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not
be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener
should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS.
Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste
only.
ADDITIONAL CONSTRUCTION NOTES
lf design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of
freezing. The pump shall have an audible and visual alarm notification in the event of excessively high-
water conditions and shall be connected to a control breaker separate from the high-water alarm breaker
and from any other control system circuits. The pump system shall have a switch so the pump can be
manually operated.
Excavation equipment must not drive in the excavation of the STA due to the potential to compact soil.
Extensions should be placed on all septic tank components to allow access to them from existing grade.
Backfill over the STA must be uniform and granular with no material greater than minus 3-inch.
LIMITS:
The design is based on information submitted. lf soil conditions encountered are different from conditions
described in report, CBO lnc. should be notified. All OWTS construction must be according to the county
regulations. Requirements not specified in this report must follow applicable county regulations. The
contractor should have documented and demonstrated knowledge of the requirements and regulations of
the county in which they are working. Licensing of Systems Contractors may be required by county
regulation.
Please call with questions.
Sincerely,
CBO lnc.

Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.

Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the

Biotube
Filtering
Process
Effluent from the
relatively clear zone
of the septic tank,
between the scum
and sludge layers,
horizontally enters
the Biotube Effluent
Filter. Effluent then
enters the annular
space between the
housing and the
Biotubes, utilizing
the Biotubes'entire
surface for filtering.
Particles larger than
the Biotube's mesh
are prevented from
leaving the tank.
