Subsurface Investigation and Onsite Wastewater Treatment System Design
3-Bedroom Farmhouse + Office Building (4 employees)
6094 CR 320
Garfield Cou nty, Colorado
Terry,
CBO lnc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OWTS) design for the subject residence. The 1340.127-acre propefi is located outside of Rifle, in an
area where OWTSs and wells are necessary.
Legal Description: Section: 26 Township: 6 Range:94 52, S2NE, SENW (NET37.20AC) LYING SE OF
co. RD 320, NENW (NET 2.77AC). ALSO THAT 7.091 AC. TRACT OF LAND ADJUSTED PER
RECEPTION NOS. 989822,989823 & 990300 Section: 25 SWNE, S2NW, 52. Section: 27 SEC 27 SE
(NET 10e.80AC)
Parcel lD: 2'175-264-00-177
SITE CONDITIONS
This large, agricultural property is currently developed with agricultural structures and two residences.
The subject portion of the property is developed with a farmhouse and several agricultural structures.
The proposed OWTS willserve the 3-bedroom farmhouse and a log structure that may be converted into
office space for up to 4 employees in the future.
A well will serve the structures on the property potable water. The well must be at least S0-feet from the
proposed septic tank and at least 100-feet from the proposed soil treatment area (STA).
A spring bo></tank captures water from a spring to the northeast of the farmhouse. Overflow from this
collection point runs to the south and is labeled as "spring drainage" on the site plan. Any OWTS
component must be at least S0-feet from the spring drainage. lt is important that all spring drainage
is captured and diverted via this drainage. lf there is any uncaptured drainage from the spring, it
must be addressed to prevent impact on the OWTS. This may require consultation with a civil
engineer.
The proposed soil treatment area (STA) is located to the northeast of the driveway and south of the
farmhouse. The area has an approximate 1O to 12o/o slope to the southwest.
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 subsurfa@ was investigated on June 6,2024 by digging two soil profile test pit excavations (Iest 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 medium brown loam to a maximum depth explored
of 4.0-feet where digging refusal was encountered on large boulders. No bedrock or groundwater was
encountered.
The materials encountered in Test Pit #2 consisted of medium brown loam with some large boulders to a
maximum depth explored of 7.O-feet. We did note some moist soils in the uphill corner of the test pit at
approximately 5 to 6-feet. This could be the result of uncaptured drainage from the spring collection
which will need to be addressed as part of this design/installation. 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 than 1-inch in length before breaking. Soil structure
shape was blocky and consistence was friable. Soil 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 50. The map unit name is Onley Loam, 3 to 6% slopes.
Typicaisoil profile from 0 to 12-inches consist of loam, 12 to 33-inches consist of sandy clay loam, 33 to
43-inches consist of gravelly sandy clay loam, and 43 to 60-inches consist of very gravelly sandy loam.
Based on information provided from the available documented resources and our onsite evaluation of the
soil, the soil is consistent with Soil Type 2, Loam, with moderate structure grade. Soils have less than
35% rock. We are proposing a pressure-dosed, unlined sand filter with a minimum of 2-feet of sand filter
material (Secondary Sand). A long-term acceptance rate (LTAR) of 0.8 gallons per square foot will
be used to design the STA.

DESIGN SPECIFICATIONS
The existing septic tank serving the farmhouse 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. The existing STA will be
abandoned in place.
Desiqn Calculations:
AverageDesignFlow=T5GPDx2people/bedroomx3Bedrooms=450GPD+(4employeesx15GPD)=
510 GPD
LTAR = 0.8 GPD/SF
510 GPD / 0.8 GPD/SF = 637.5 SF
Septic Tank Capacity:
Farmhouse = min. 1O0O{allons
Log Structure/Office = min. 1OOO-gallons (tuture)
The OWTS design is based on 3-bedrooms in the farmhouse and 4 employees for future use of the log
structure as an office space. An average daily wastewater flow of 510 GPD will be used. The farmhouse
construction will be completed near term; therefore, the septic tank, pump chamber, and STA will be
installed first. When the log structure/office building permit is submifted, a permit for a septic tank only
must be applied for, and at that time, the pump chamber may be moved to the lowest elevation and
p u m p i ng p a rameters re-eval u ated.
For the purposes of this OWTS design, Benchmark Elevation at grade 5395' has been established as
100' (Finished Floor of the farmhouse). 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.
We recommend installing a new 4-inch SDR-35 sewer line from the farmhouse to the new septic tank
with a double-sweep clean out and a minimum 2o/o grade. lf the existing sewer line will remain in use, it
must be explored with a camera to assure it is in good condition.
The system installation will include a 1OO0-gallon, two-compartment lnfiltrator@ poly septic tank with an
Orenco@ Biotube Effluent Filter on the outlet followed by a SO0gallon, single-compartment lnfiltrator@ poly
pump chamberwith Orenco Biotube ProPak and an Orenco@ PF5005 pump. Any state-approved poly or
concrete septic tanks may be substituted. The floats should be set to dose approximately 65 gallons each
pump cycle, allowing approximately 2.5 gallons of drain back. The control panel forthe pump must be
located within line of sight of the septic tank. An electrician will be responsible for wiring the pumping system
and the contractorwill be responsible for connecting the plumbing. This office should be contac'ted for stiart
up of the system to veriff its functioning and to perform a squirt test prior to use of the system.

Pump Criteria
Page 6
Pum
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 1o/o grade for proper
drain back into the pump chamber after each pump cycle. The ADV must be placed at a high point in the
system in an insulated riser with a@ess 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 two 1O' x32 beds. A minimum
of 2-feet of sand filter materialwill be instralled in the over-excavated footprintrs. 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 coefiicient 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 submitted to this office prior to obtaining the sand.
Laterals must be 1.S-inches in diameter with 5/32-inch diameter orifices facing down, spaced 2-feet on
center, installed on the GeoMatil 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.S-inch
diameter level manifolds. Three 39'wide GeoMatsru must be placed on the 1O-foot wide beds. All material
associated with the GeoMatru installation must be proprietary products associated with the GeoMatrM,
including orifice shields and geotextile fabric. Manufacturer instructions must be followed regarding
installation of the GeoMatru.
Each 1.S-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. A screw
cap should be installed on the end of the flushing valve with a 5132" orifice drilled in the cap for the
purpose of running the squirt test. 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
GeoMatw. lnspection ports must be placed at each corner of each bed. Ports may be cut to grade and
covered with a valve box for access.
COMPONENT SPECIFICATIONS
The component manufacturers are typical of applications used by contractors and engineers in this area.
GBO 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.

Department, 970-945-661 4 x81 50.
I NSTALLATION 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 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 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 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 REQUIREM ENTS
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 inigation 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
@ver.
OPERATION INFORMATION AND MAINTENANCE
The property owner shall be responsible for the operation and maintenance of each OWTS servicing the
property. The properly owner is responsible for maintaining service contrac'ts 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 re@mmend 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.

MAP LEGEND MAP INFORMATION
The soil surveys that comprise your AOI were mapped at
1:24,ffiO.
Waming: 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.
Please rely on the bar scale on each map sheet for map
measurements.
Source of Map: Natural Resources Conservation Service
Web Soil Survey URL:
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projedion, which preserves direction and shape but distorts
distance and area. A projec'tion that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distrance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Rifle Area, Colorado, Parts of Garfield and
Mesa Counties
Survey Area Data: Version 16, Aug 22, 2023
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Aug 25, 2021-Sep
5,2021
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
