Subsurface lnvestigation and Onsite Wastewater Treatment System Design
3-Bedroom Residence
Lot 21, Mountain Springs Ranch
Garfield County, Colorado
Matt,
GBO lnc. performed a subsurface investigation and completed an onsite wastewater treatment system
(OWTS) design for the subject residence. The 35.139-acre property is located outside of Glenwood
Springs, in an area where OWTSs and wells are necessary.
Legal Description: Section: 29 Township: 6 Range: 89 A TR lN SW AKA LAT 21 MOUNTAIN SPRINGS
RANCH
Parcel lD: 21 85-293-00-1 09
SITE CONDITIONS
The property is currently undeveloped. A 3-bedroom residence is proposed.
The residence will be served by a private well on the property. The well had not been drilled at the time
of this design but will be greater than S0'feet from the proposed septic tank and greater than 1O0-feet
form the proposed soiltreatment area (STA).
The proposed soil treatment area (STA) location has an approximate 15 percent slope to the south. The
proposed area is vegetated with sage, native grasses, and sparse trees.
High groundwater was encountered in the area of the proposed STA and mounding will be necessary.
There should be no traffic or staging of material over the future STA slte to avoid compactlon of soils
prior to construction of the STA.
SUBSURFACE
The subsurface was investigated on April 7,2025 by digging one soil profile test pit excavation (Test Pit). A
visual and tactile soil analysis was mmpleted by Cada Ostberg at the time of excavation.l
The materials encountered in Test Pit #1 consisted of moist, dark brown topsoil to 2.0-feet, underlain by
moist, reddish brown clay loam to a maximum depth explored of 6,0-feet. Free groundwater entered the
uphill side of the test pit at approximately 1-foot below grade.
' Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile
Evaluation of Soils Training.
Page 2
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 1 to 2-inches in length before breaking, Soils were very
moist and difficult to run the tactile evaluation.
The soil is consistent with Soil Type 3, Clay Loam, with moderate structure grade. Mounding of the
STA will be necessary due to the presence of high seasonal groundwater. A mounded, unlined
sand filter with a minimum of 3-feet of sand filter material to create the required separation between the
infiltrative area and high season groundwater is proposed. A long-term acceptance rate (LTAR) of 0.65
gallone 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 = 450 GPD
LTAR = 0.65 GPDiSF
450 GPD / 0.65 GPDiSF = 692 SF
Please see enclosed Mound Sysfem Design Spreadsheef forslope information
The OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD will be used,
For the purposes of this OWTS design, Benchmark Elevation at grade 7698.06' 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 upon standard OWTS installation practices. Component elevations may change during
installation due to site conditions. Minimum grade refers to piping between components.
The 4{nch 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 1OOO-gallon, two-compartment lnfiltrator@ poly septic tank with an
Orenco@ Biotube Effluent Filter followed by a 500gallon, single-compartment lnfiltrator@ poly Pump Vault

and an Orenco@ PF3005 pump. The floats should be set to dose approximately 65 gallons each pump
cycfe, allowing approximately 2 gallons of drain back. The control panel for the pump must be located
within line of sight of the septic tank. An electrician 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 verifu its functioning and to perform a squirt test prior to use of the system.
P Table
Effiuent will be pumped through a 1.5-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 tank after each pump cycle. The ADV must be placed at a high point in the system in an
insulated riserwith 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 1.5-inch diameter distribution lines to two 10' x 35' beds (which
can be set end to end with distribution piping extending f in from the touching ends of the sand filters. A
minimum of 3-feet of sand filter material beginning 1-foot below native grade the uphill side of the sand fllter.
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 medla must be submitted to this office prior to obtaining the
sand.
Laterals must be 1.5-inches 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. Three 39" wide GeoMatsrM must be placed on the 10-foot wide beds. All material
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 soilseparation
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. Inspection ports must be placed at
each corner of each bed, Ports may be cut to grade and covered with a valve box for access.
The mound must have a minimum 3:1 slope (horizontal:vertical); therefore, the basalarea will extend
approximately 9-feet beyond the sand filter the downhill side and ends (with a mound height of approximately
3.S-feet above native grade). Soils in the sloped perimeter areas of the mound must be well draining and
able to support vegetative growth. This soil must be approved by this office prior to installation. The
mound must be crowned in a manner to promote drainage off the STA. More details are provided
regarding sloping areas off of the mound and depth of sand as the sand filters are built into the
hillside in the enclosed Mound Sysfem Design Spreadsheet and W3.0/1 and 2 Mound Plan and
Section Views.

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, lncluding 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 REQU IREMENTS
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
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,
Page 7
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,
