Subsurface lnvestigation and Onsite Wastewater Treatment System Design
2-Bedroom Residence
11749 CR 31 1
Garfield County, Colorado
Caet,
CBO lnc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OffiS) design for the subject residence. The 735,464-acre property is located outside of Silt, in an area
where OWTSs and wells are necessary. A new site plan with the correct house footprint has been
provided since our original design documents dated December 26, 2024. Those should be discarded and
replaced with design documents dated January 8,2025.

SITE CONDITIONS
The property is currently developed with a 2-bedroom residence that is being renovated. The existing
OWTS is not documented and will be replaced with the OWTS outlined in this design.
The residence will be served by a private well on the property. The existing well will be abandoned and a
new will be drilled. The well will be located greater than 5O-feet from the proposed septic tank and
greater than 1OO-feet from the proposed soil treatment area (STA).
West Divide Creek runs to the west of the residence. No OWTS component will come within SO-feet of
West Divide Creek.
A wetland is also present to the north of the proposed STA, The wetland will not come within 5O-feet of
the STA.
A drainage structure has been partially constructed between the driveway and proposed STA. We
recommend this structure be completed with an ADS pipe or other infrastructure to assure no
downgradient over-flow or leakage.
Any water lines, including ranch hydrants, in the area of the proposed STA must be removed.
The proposed soil treatment area (STA) location has an approximate ten percent slope to the west
towards Divide Creek. The proposed area is vegetated with native grasses, but was covered with snow
at the time of our site visit.

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 December 3,2024 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 silt loam topsoil to 2.O-feet, underlain by
moist, dark brown silt loam becoming more sandier with depth to a maximum depth explored of 4.0-feet.
Groundwater was encountered and filled the test pit to approximately 3-feet below native grade. Test Pit #1
was excavated at an approximate elevation of 6354'.
The materials encountered in Test Pit #2 consisted of dark brown clay loam topsoil to 1 .0-foot, underlain by
dense, medium brown clay loam to S.O-feet, underlain by moist to very moist clay loam a maximum depth
explored of 8.0-feet. No bedrock or groundwater was encountered, but soils became moist below 5.0-feet.
Test Pit #2was excavated at an approximate elevation of 6358'.
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 than f -inch in length before breaking. Soilstructure
shape was blocky and consistence was friable. Soil texture was more smooth than gritty.
A sample of the soils was taken from Test Pit #2 at 3-feet below grade. Soil structure was weak. The
soilformed a ball and a ribbon between 1 and 2-inches in length before breaking. Soilstructure shape
was blocky and consistence was firm. Soil texture was both gritty and smooth.
We have researched soils in the area through USGS Web SoilSurvey. The report is enclosed. The area of
the proposed STA is identified by map unit symbol 65. The map unit name is Torrifluvents, nearly level.
Typical soil profile from 0 to 36-inches consists of loam and from 36 to 60-inches consists of sand.
While soils in the area of Test Pit #2 consisted of more clay content, the limiting layer of groundwater was
encountered in the area of Test Pit #1.
' Carla Ostberg holds a Certificate of Attendance and Examination from the CPOWVisualand Tactile
Evaluation of Soils Training.

The soil in the area of the proposed STA is consistent with SoilType 3A, Clay Loam, with weak structure
grade. A pressure-dosed, over-excavated, unlined sand filter with a minimum 2-feet of sand filter
material (Secondary Sand) is proposed. Depth to the bottom of the sand filter may not exceed 4-feet
below native grade. A long-term acceptance rate (LTAR) of 0.55 gallons per square foot will be
used to design the STA.

DESIGN SPECIFICATIONS
The existing septic tank (located on the survey provided to us) will be abandoned by pumping the tank
and removing it or crushing the top, bottom, and sides and filling in the void with onsite materials. We
have no information on the existing STA which will be abandoned in place.
Desion Calculations:
Average Design Flow = 75 GPD x 2 people/bedroom x 2 Bedrooms = 300 GPD
LTAR = 0.55 GPD/SF
300 GPD / 0.55 GPD/SF = 545 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 at grade 6359' 1 112" has been established
as 100' (Finished Floor). 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.
The system installation will include a 1O00-gallon, two-compartment Valley Precast concrete septic tank
with ah Orenco@ Biotube Pump Vault and an Orenco@ PF3005 pump in the second compartment of the
septic tank. The floats should be set to dose approximately 54 gallons each pump cycle, allowing
approximately 4 gallons of drain back. The control panel for the pump must be located within line of sight
oi ine septic tant. nn ebctrician will be responsible for wiring the pumping system and the contractor will be
responsible for connecting the plumbing, This office should be contacted for start up of the system to veriff
its functioning and to perform a squirt test prior to use of the system.
Table
Effluent will be pumped through a 1.S-inch diameter pump line from the pump chamber to an Orenco@
automatic distributing valve (ADV), model 6402. This pump line must have a minimum 1% grade for proper
drain back into the tank after each pump cycle. The ADV must be placed at a high point in the system in an
insulated riser with access from grade. Screened rock must be placed below the ADV to support the ADV
and to assure the clear pipes exiting the ADV remain visible for future inspection and maintenance'
Effluent will be pressure dosed to through 1 .S-inch diameter distribution lines to a 13' x 42' bed. The depth
of the excavation must not exceed 4-feet below native grade. A minimum of 2-feet of sand filter material
will be installed in the over-excavated footprint. 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 uniformif coefficient must be 7.0 or less. Materialmeeting 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
submitted to this office prior to obtaining the sand.
A 30 mil PVC liner must be placed on the uphill side of the excavation for the sand filter. The liner
should extend from the top to the bottom of the sand filter on the north (uphill side) of the sand
filter to provide protection from any upgradient drainage.
Laterals must be 1.Sinches in diameter with 5/32-inch diameter orifices facing down, spaced 3-feet on
center, installed on the GeoMatrM with the filter fabric over the laterals. Laterals should be placed 2-feet
from the edges of the bed with 3.0-feet between the laterals. Laterals will be connected with 1 .5-inch
diameter level manifolds. Four 39" wide GeoMatrM sheets must be placed on the 13-foot wide bed' All
mate6al associated with the GeoMatrM installation must be proprietary products associated with the
GeoMatrM, including orifice shields and geotextile fabric. Manufacturer instructions must be followed
regarding installation of the GeoMatrM.
Each 1.S-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. Valves
should be placed in a 1O-inch sprinkler box for access. Laterals must be covered by a soil separation
fabric and at least 1-foot of topsoil or other suitable soil able to support vegetative growth. There shall be no
cobble-sized (>2.5') or greater rock in final cover over the GeoMatrM. lnspection ports must be placed at
each corner of the bed. Ports may be cut to grade and covered with a valve box for access.

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 corners or another fixed
objects on the property. This sketch is most easily provided on Sheet \ 2.0 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 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.
Page 9
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.
