Subsurface lnvestigation and Onsite Wastewater Treatment System Design
2-Bedroom Residence + Future 4-Bedroom Residence
TBD Panorama Drive
Garfield County, Colorado
Ryan,
CBO lnc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OWTS) design for the subject residence. The 5.09-acre property is located outside of Carbondale, in an
area where OWTSs and wells are necessary.
Legal Description: Section: 17 Township: 7 Range: 87 TR lN N1/2NW5.09 ACRES
Parcel lD: 2391-172-00-1 30
stTE conDrTtol{s
The property is cunently undeveloped. A 2-bedroom residence is proposed. A future 4-bedroom
residence is also contemplated.
The residences will be served by a shared well located on the adjacent property to west. The well is
approximately 750-feet northwest of the proposed residence. The water line willcome within 2S-feet of
any OWTS component.
The proposed soiltreatment area (STA) location has an approximate fifteen percent slope to the east.
The proposed area is vegetated with sage, native grasses, and scrub oak.
There should be no tsaffic or staging of material over the fufure STA site to avoid compaction of soils
priorto constuction of the STA.
SUBSURFACE
The subsurface was investigated on October 18,2024 by digging three 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 clay loam topsoil to l-foot, underlain by
tan to whitish calcareous clay matrix with sporadic large basalt boulders to a maximum depth explored of
6.0-feet. No bedrock or groundwater was en@untered.
tCarla Ostberg holds a Certificate of Attendance and Examination from the CPOWVisualand Tactile
Evaluation of Soils Training.

The materials encountercd in Test Pit#2 consisted of dark brown clay loam topsoil to 18-inches, underlain
by tan to whitish calcareous clay matrix to a maximum depth explored of 4.O-feet where practical digging
refusal on a large boulder was encountered. No bedrock or groundwater was encountered.
The materials encountered in Test Pit#0 consisted of dark brown clay loam topsoil to 1-foot, underlain by
tan to whitish calcareous clay matrix with scattered cobbles and large basalt boulders to a maximum
depth explored of 4.O-feet. Encountering similar soil conditions as pervious test pits, we opted to
discontinue digging. No bedrock or groundwaterwas en@untered.
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 struclure
shape was blocky and consistence was friable to firm. $oil texture was both gritty and smooth.
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 symbol 87. The map unit name is Morual-Tridellcomplex, 12 to
50% slopes.
The calcareous clay matrix horizon is consistent with Soil Type 2 with moderate structure grade. \ /hile
large basalt boulders were en@untered, they are sporadic. A long-term acceptance rate (LTAR) of 0.6
gallons por square foot will be used to design the STA.

DESIGN SPECIFIGATIONS
Desion Calculations:
2-Bedroom Residence = 75 GPD x 2 people/bedroom x 2 Bedrooms = 300 GPD
Future4-BedroomResidence=TbGPDx2people/bedroomx3Bedrooms+75GPD(+sbedroom)=52S
GPD
Average Design Flow = 300 GPD + 525 GPD = 825 GPD
LTAR = 0.6 GPD/SF
825 GPD / 0.6 GPD/SF = 1375 SF x 1.0 (gravrty, trenches) x 0.7 (GeoMatw with min. 6" sand filter material)
= min. 962.5 SF
The OWTS design is based on a 2-bedroom residence and a future 4-bedroom residence. An average
daily wastewater flow of 825 GPD will be used.
For the purposes of this OWTS design, Benchmark Elevation at grade 7217' has been established as
100' (Finished Floor of the 2-bedroom residence). CBO 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 residence must have a double-sweep clean out and a minimum
2o/o grade to the septic tank. \Mrere the sewer line crosses the driveway, it must be minimum Schedule
40. lf desired, it may be placed in a larger diameter minimum Schedule 40 conduit. lf the sewer line run
extends further than 1O0-feet, an additional clean out must be installed.
The system installation must include a 2000-gallon, two-compartment Valley Precast concrete septic tank
with an Orencot0 Biotube effluent filter on the outlet tee. 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.
Effluent will gravity flow to a distribution box, and then to six 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 be 3' x 54' trenches with a minimum of 6-inches of sand filter material under a 39" wide
sheet of GeoMatil. Sand filter material must be clean, coarse sand, all passing a screen having four
meshes to the inch. The sand must have an effective size between 0.15 and 0.60 mm. The uniformity
coefficient must be 7.0 or less. Material meeting ASTM 33, for concrete sand, with three percent or less
fines passing 200 mesh sieve may be used. A gradation of the sand media must be submifted to this

The six total trenches will total324lineal feet of GeoMatw and 972 square feet of infiltrative area. There
must be at least 4-feet of undisturbed soil between each trench. Laterals must be perforated 4-inch
diameter pipe set down the center of each 39" wide GeoMatil sheet. The gray GeoMatil separation fabric

willcoverthe laterals. All materialassociated with the GeoMatil installation must be proprietary products
associated with the GeoMatil. Manufacturer instruc{ions must be follqred regarding installation of the
GeoMatru.
lnspection ports must be installed at the beginning and end of each trench, into the sand filter material.
Clean outs (inspection ports) must also be installed at the end of each perforated lateral. 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.
GBO 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€ite Wastewater Treatment System
Regulations, the OWTS Permit, and this design.
PERMIT APPLICATION INSTRUCTIONS
An OWTS PermitApplication must be submitted to Garfield County Environmental Health Department.
https://www.oarfield-county.com/environmental-health/filesqcco/sites/16/OWTS-Apolication-Complete-
PackelDec.-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, 970-945-661 4 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 offce 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 ofiice 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
PageT
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 aewer lines, water line installation (if applicable),
septic tank location, STA location, and measuremenb from building corners or another fixed
obiects on the property. This sketch is most easily provided on Sheet \A2.0 of the OWTS Design
Packet. Photographs of the installation and finalcover 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
charac{eristics (but without taproots), provides a maximum transpiration rate, and competes well with
successional species. No trees or shrubs, or any vegetation rcquiring 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 O\A/TS shall be responsible for maintaining proper vegetation
cover.
OPERATION INFORMATION AND MAINTENANCE
The propefi owner shall be responsible for the operation and maintenan@ of each OWTS servicing the
prop6rty. The property owner is responsible for maintaining service contracts for manufactured units,
altemating 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 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 OW[S. 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 ftom the high-water alarm breaker
and from any other control system circuits. The pump system shall have a switch so the pump can be
Excavation equipment must not drive in the excavation of the STA due to the potentialto compact soil.
Extensions should be placed on allseptic 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 submifted. 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.
