Subsurface Investigation and Onsite Wastewater Treatment System Design
4-Bedroom Residence
Lot 33, Rapids on the Colorado
Garfield County, Colorado
Justin,
Project No. C1981
CBO Inc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OWTS) design for the subject residence. The 2.0-acre property is located outside of New Castle, in an
area where OWTSs are necessary.
Legal Description: Section: 4 Township: 6 Range: 91 Subdivision: RAPIDS ON THE COLORADO Lot: 33
Parcel ID: 2181-043-07-033
SITE CONDITIONS
The property is currently undeveloped. A 4-bedroom residence is proposed.
The residence will be served by a community water system with the water line entering the property from
the shut off to the north. The water line must be at least 10-feet from the septic tank and at least 25-feet
from the soil treatment area (STA).
The proposed STA location has an approximate 2 to 3 percent slope to the northwest. The proposed
area is vegetated with 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 June 23, 2025 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.'
The materials encountered in Test Pit #1 consisted of dark brown topsoil to 18-inches, underlain by
medium brown sandy loam to 6.0-feet, underlain by sand and cobbles to a maximum depth explored of
7.0-feet. No bedrock or groundwater was encountered.
The materials encountered in Test Pit #2 consisted of medium brown sandy loam to 2-feet, underlain by
light brown sandy loam to 6.0-feet, underlain by sand and cobbles to a maximum depth explored of 7.0-

Evaluation of Soils Training.

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 soil formed a ball and a ribbon less than 1-inch in length before breaking. Soil structure
shape was blocky and consistence was firm to extremely firm. Soil texture was more gritty than smooth.
With sand and cobbles encountered at 6-feet, the infiltrative area can be installed NO DEEPER than 2.0-
feet below grade to assure 4-feet of suitable soils prior to encountering the Type R-0 soils.
The soil is consistent with Soil Type 2, Sandy Loam, with moderate structure grade. A long-term
acceptance rate (LTAR) of 0.6 gallons per square foot will be used to design the STA.

DESIGN SPECIFICATIONS
Design Calculations:
Average Design Flow = 75 GPD x 2 people/bedroom x 3 Bedrooms + 75 GPD (4t" Bedroom) = 525 GPD
LTAR = 0.6 GPD/SF
525 GPD / 0.6 GPD/SF = 875 SF x 1.0 (gravity, trenches) x 0.7 (chambers) = 612.5 SF
The OWTS design is based on 4-bedrooms. An average daily wastewater flow of 525 GPD will be used.
For the purposes of this OWTS design, Benchmark Elevation at grade 5404.75' has been established as
100' (Finished Floor). CBO Inc. 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 residence must have a double -sweep clean out and a minimum
2% grade to the septic tank.
Page 5
The system installation must include a minimum 1250-gallon, two -compartment poly septic tank with an
Orenco® Biotube effluent filter on the outlet tee. We have specified a 1500-gallon, two -compartment
Infiltrator® poly septic tank as they are locally available. Any state -approved concrete or poly septic tank
may be substituted. 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 four 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 trench.
Each trench will consist of 13 `Quick 4' Standard Plus Infiltrator® chambers for a total of 52 chambers
and 624 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.
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.

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.
htt s://www. arfield-count .com/environmental-health/files cco/sites/16/OWTS-Application-Com lete-
Packet-Dec.-2019.Ddf. If the OWTS Permit Application will be submitted with a Building Permit
Application, it should be submitted directly to Garfield County Building Department.
All questions regarding permit submission can be directed to Garfield County Environmental Health
Department, 970-945-6614 x8150.
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
Page 6
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
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
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
Page 7
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. If soil conditions encountered are different from conditions
described in this 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.
Please call with questions.
Sincerely,
CBO Inc.
