Onsite Wastewater Treatment System (OWTS) Installation Observations
13000 Cottonwood Pass Road
Eagle County, Colorado
Permit # OWTS-020821-2021
Brian,
CBO Inc. observed the installation of the onsite wastewater treatment system (OWTS) on May 20, 2021
for the subject property. Tonka Excavation installed the system.
The OWTS design is based on 2-bedrooms (two 1-bedroom cabins). An average daily wastewater
flow of 300 GPD was used.
A pond (Von Springs Reservoir #1) fills seasonally and is located to the east of the proposed
development. The soil treatment area (STA) was measured at 60-feet from the high water mark of the
Reservoir.
A 4-inch diameter Schedule 40 (because of location under driveway) sewer line will be installed with a
double-sweep clean out and min. 2% fall to the septic tank.
The system installation included a 1000-gallon, two-compartment Infiltrator® poly septic tank with an
effluent filter on the outlet tee. This filter must be cleaned annually, or as needed. Risers bring the
manhole lids to grade for access.
Effluent gravity flows to a distribution box, and then to three gravelless chamber trenches. The
distribution box was accessible from grade with flow equalizers installed on each outlet pipe in the
distribution box to assure equal flow to each trench. Each trench consists of 8 ‘ADS’ ARC 36 chambers
for a total of 24 chambers and 360 square feet of infiltrative area. There was at least 4-feet of
undisturbed soil between each trench. Installation of the chambers did not exceed more than a foot
below native grade and the area was regraded to achieve a minimum 1-foot of cover over the chambers.
Inspection ports were installed at the beginning and end of each trench. Ports may be cut to grade and
placed in sprinkler boxes for access.
The OWTS was generally installed according to specifications. This observation is not a guarantee of
workmanship and/or parts and materials. CBO Inc. should be notified if changes are made to the OWTS
in the future. Any additional OWTS construction must be according to the county regulations.
LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must
have documented and demonstrated knowledge of the requirements and regulations of the county in
which they are working. The quality of the installation is dependent on the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
CBO Inc.

Subsurface Investigation and Onsite Wastewater Treatment System Design
(2) 1-Bedroom Cabins
TBD Cottonwood Pass Road
Eagle County, Colorado
Brian,
CBO Inc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OWTS) design for the subject residences. The 35.33-acre property is located outside of Carbondale, in
an area where OWTSs and wells are necessary.
Legal Description: Subdivision: COULTER CREEK RANCHES Lot: 4 BK-0334 PG-0437
BK-0472 PG-0981 WD 10-31-84
BK-0704 PG-0363 MAP 09-04-96
Parcel ID: 2189-224-01-003
SITE CONDITIONS The property consists of a portion of the lot on the west side of Cottonwood Pass Road and the other
portion on the east side. The western portion of the property is developed on the west side of
Cottonwood Pass Road with a single-family residence (270 Buck Point Drive) that is served by an
OWTS. The subject proposed development includes two 1-bedroom cabins located on the east side of
Cottonwood Pass Road.
The subject portion of the property adjacent to Cottonwood Pass Road includes a relatively flat bench,
which then slopes to the northeast and east toward the pond.
A pond (Von Springs Reservoir #1) fills seasonally and is located to the east of the proposed
development. No portion of the OWTS will come within 50-feet of the pond.
The well that serves the single-family residence will also serve the cabins. The well is located greater
than 50-feet from the proposed septic tank and greater than 100-feet from the proposed STA. The water
line should not come within 25-feet of any OWTS component.
The proposed STA is covered with native grasses and sage. The area slopes to the northeast with an
approximate 13-15% slope.
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.
Page 2
SUBSURFACE The subsurface was investigated on September 30, 2020 by digging two soil profile test pit excavations (Test
Pits). Visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1
The materials encountered in Test Pit #1 consisted of dark brown loamy topsoil to 3.5-feet, underlain by
reddish brown loam to 5.0-feet, underlain by greenish loam to a maximum depth explored of 6.5-feet. No
bedrock or groundwater was encountered.
The materials encountered in Test Pit #2 consisted of dark brown loamy topsoil to 5.0-feet, underlain
loam with evidence of mottling to a maximum depth explored of 6.0-feet. No bedrock or groundwater was
encountered.
A sample of the soils was taken from the topsoil horizon in Test Pit #1. Soil structure grade was
moderate. The soil formed a ball and a ribbon less than 1-inch in length before breaking. Soil structure
shape was blocky and consistence was friable. Soil texture was both smooth than gritty.
A sample of the soils was taken from approximate 5-feet below grade in Test Pit #1. Soil structure grade
was moderate. The soil formed a ball and a ribbon less than 1-inch in length before breaking. Soil
structure shape was blocky and consistence was firm. Soil texture was both smooth than gritty.
STA sizing is based on Soil Type 2, Loam with moderate structure. A long term acceptance rate
(LTAR) of 0.6 gallons per square foot will be used to design the OWTS. The infiltrative area will not
be placed more than 1-foot below native grade.

DESIGN SPECIFICATIONS
Design 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 x 1.0 (gravity trenches) x 0.7 (chambers) = 350 SF
The OWTS design is based on 2-bedrooms. 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’ as the sewer
line exiting the residence. CBO Inc. should be notified of any discrepancies or problems with grade
elevations of proposed components during installation of the OWTS.
OWTS Component Minimum Elevation
Primary Tank Inlet Invert Approximate horizontal distance 23’ / min. 2% fall /
min. 5.75” fall
Distribution Box Approximate horizontal distance 15’ / min. 1% fall /
min. 1.875” fall
Infiltrative Surface (upper-most trench Approximate horizontal distance 10’ / min. 1% fall /
min. 1.25” fall
A 4-inch diameter Schedule 40 (because of location under driveway) sewer line will be installed with a
double-sweep clean out and min. 2% fall to the septic tank.
The system installation must include a 1000-gallon, two-compartment Infiltrator® poly septic tank with an
effluent filter on the outlet tee. Risers must bring the manhole lids to grade for access. If more than one
riser is added to the septic tank, an extension handle must be installed on the effluent filter.
Effluent will gravity flow to a distribution box, and then to three gravelless chamber trenches. The
distribution box must be accessible from grade and must have flow equalizers, or similar product,
installed on each outlet pipe in the distribution box to assure equal flow to each bed.
Page 7
Each trench will consist of 10 ‘Quick 4’ Low Profile Infiltrator® chambers for a total of 30 chambers and
360 square feet of infiltrative area. There must be at least 4-feet of undisturbed soil between each
trench. Inspection ports must be installed at the beginning and end of each trench. Ports may be cut to
grade and placed in sprinkler boxes for access.
The infiltrative area must be NO DEEPER than 1-foot below native grade. Regrading over the
trenches will be necessary to achieve minimum 1-foot of cover over the chambers.
COMPONENT SPECIFICATIONS
The component manufacturers are typical of applications used by contractors and engineers in this area.
CBO Inc. 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.

The component manufacturers are typical of applications used by contractors and engineers in this area.
Alternatives may be considered or recommended by contacting our office. Construction must be
according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided
by Eagle County Environmental Health Department, and this design.
INSTALLATION CONTRACTOR
CBO Inc. 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 additional conditions 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 Inc. 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 Inc. should be notified 48 hours
in advance to observe the installation.
In 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 corners or another fixed
objects on the property. This sketch is most easily provided on Sheet W2.0 of the OWTS Design
Page 8
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 area. 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
construction of the STA for better weight distribution. Livestock should not graze on the STA. Plumbing
fixtures should be checked to ensure that no additional water 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.
If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned
annually, or as needed. If 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 If 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.
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. If soil conditions encountered are different from conditions
described in report, CBO Inc. 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.
