RE: Fulbright/McVey Residence — Proposed OWS System, Parcel 3, Lone Cottonwood
Subdivision, County Road 229, Garfield County, CO
SE Job No. 24096.01
Dear Dana:
Pursuant to your request this letter/report presents our findings in regard to the feasibility and design of an
engineered Onsite Wastewater System (OWS) for the above referenced Site. This design is based on our
evaluation of the site conditions with information provided by others for use in supporting your application
to Garfield County. Our recommendations are in accordance with Garfield County and the State of
Colorado ISDS Regulations. Garfield County must permit any proposed improvement to the site. We
have reviewed the information forwarded to us, conducted a site visit, formulated an OWS design and
created a site plan with construction details as part of our scope of work.
Conclusions
Based on our findings we believe that the design and installation of an approved OWS system is feasible in
accordance with the Regulations of Garfield County and the State of Colorado. We recommend that a
new 1500 gallon septic tank be installed that will discharge effluent to a 500 square foot soil absorption
trench system. The soil absorption system can be installed in natural soils and will be located within the
required setbacks down gradient of the proposed house, as delineated on the attached plan. The system
will meet all required setbacks and be installed within the general boundaries indicated on the plan. Our
Design is outlined below and delineated on the attached site plan.
Site Location and Existing Conditions
The subject site is located on Parcel 3 in the Lone Cottonwood Subdivision on County Road 229 in
Garfield County, Colorado. The site is situated in Section 4, T 6 S, R 92 W of the 6`h P.M. The Site
comprises approximately 3.6 acres. The site is bounded on the north, east and west by agricultural lands
with scattered single-family homes and out buildings. The site is located on previous agricultural lands.
The site has a gentle slope (1%-2%) southwestward. The site is covered with pasture grasses. Domestic
water will be supplied by an onsite well serving the three parcels in the subdivision and location over 300'
away from the proposed absorption field. There are no other wells within 100' of the general vicinity of
the absorption field.
Proposed Site Conditions
It is our understanding that you intend to construct a 4 -bedroom home. The maximum number of rooms to
be utilized as bedrooms in the structure is 4. The proposed improvements will include a new OWS
system with appropriate site grading. The new structure is to be generally located as shown on the plan.

Subsurface Conditions
A subsurface investigation and percolation test was conducted in May 2004 by Hepworth-Pawlak
Geotechnical, Inc (HP). The subsoil encountered at the site consists of 1/2 —1 foot of topsoil overlying 5-7
feet of sandy, silty clays overlying silty sandy gravel and cobbles to an observed depth of 9 feet.
Groundwater was not encountered in the excavations.
Percolation testing utilized three test holes, which yielded similar absorption rates. The fastest measured
rate was 8 minutes per inch and the slowest measured rate was 10 minutes per inch. The average
percolation rate is 9 minutes per inch and should be suitable for a conventional absorption system.
Design Criteria
The design flow is calculated as follows:
Single family home — equivalent 4 bedroom population @ 2 person /bedroom = 8 persons.
From the Garfield County I. S. D. S. Regulation:
Max. Design flow (Qd) = # of people x (avg. flow) x 1.5 gal/person/day.
Gallons per day per person for the subject house = 75 gal/person/day
Assume 8 -person population
Qd = 8*75*1.5* =1050 gal/day
Septic Tank Design
Based on Design Flow Qd.
Qd = 1050 gal/day
Volume (V) of tank = Design Flow * 1.25
(30 hour retention time)
V = 675 gal/day * 1.25 days = 1312 gallons
Use one 1500 -gallon dual compartment concrete septic tank

Soil Absorption System Desian
The field is sized by using the standard absorption area equation. A soil absorption trench system,
utilizing gravelless chambers is recommended. The State allows a 50% area reduction for the use of
gravelless infiltration chambers in a trench configuration. The chamber units may be installed in native
soils. Soil replacement with sand may be used in select locations if any scattered cobbles or rocks are
encountered. We are using 20 minutes/inch for design to account for permeability through the biomat.
Based upon the design percolation rate, the standard absorption area equation is:
A (SF) = Od *(t) 1 : where A = Area; Qd = Design flow (gal/day)
5 t = time in minutes
This design calculation results in a recommended minimum absorption area:
A = 1050 *(20) X = 939 sq. ft.
5
Apply a 50% reduction for utilizing gravelless infiltration chambers in a trench configuration.
939 x 0.5 = 470sq. ft.
Use 496 SF of trench with gravelless chambers: Assume 3 -foot wide trenches with 6.25 -foot long chamber
units.
Assume 15.5 square feet per chamber: 470 sq.ft. = 30 chambers Use 32 chambers
15.5 sq.ft/chamber(50%)
We recommend using a trench system composed of 4 50 feet long and 3 foot wide, containing 8 standard
leaching chamber units in each trench. Excavate absorption trenches to accommodate a minimum 496 SF
of interior surface area.
Effluent Distribution System
A gravity distribution system will be utilized to transport effluent from the new concrete septic tank to a
distribution box and to the head chamber of each trench via an individual distribution line. An effluent
filter will be installed in the secondary compartment of the septic tank to reduce suspended solid loading to
the absorption trenches and extend the life of the treatment media in the trenches. A 4" PVC effluent line
will discharge effluent to a distribution box installed level, up gradient and adjacent to the trenches. The
4" PVC line will be installed with a minimum 2% slope. The effluent will be equally distributed from the
distribution box through individual distribution pipes to each trench in the system. The inlet in the
distribution box should have a tee or a built in baffle to dissipate the influent velocity and insure equal
distribution into each outlet discharge pipe. The discharge pipes will connect to the head of each chamber
row. Appropriate chamber end plates shall be installed on the inlet ends to prevent scouring of the trench
bottom surface. An inspection port should be installed on the top mid -point cut out at the end chamber in
each corner trench. This will mark the field and allow for checking the performance of the system over
time.

OWS Operation and Maintenance
The engineered system shall be inspected on a regular basis and be properly maintained. The
responsibility for repair and maintenance of the system will remain with the Lot Owner. The owner shall
inspect the OWS and perform maintenance and repairs necessary to ensure that the system is operating
properly. The effluent filter shall be maintained when the tank is pumped or as needed. Suitable
component handles and extensions on the filter assembly will be installed to provide easy maintenance.
We recommend a periodic inspection be performed every 6 months.
The OWS system should require minimal maintenance. Several factors influencing the need for
maintenance include: actual wastewater flows versus design flows, the volume of kitchen/domestic waste
(excluding human waste and toilet paper), excessive household chemicals and other toxic liquids. The
tank, dispersal field and other applicable treatment system components should be visually inspected bi-
annually for debris, wear, damage, leaks, or other potential problems. In general, for a properly utilized
system, septic tanks should be pumped and inspected every 2 - 4 years. The effluent filters should be
cleaned every six months and at the time of pumping. Absorption fields should be maintained with
suitable cover and kept free of root invasive plants. Positive surface drainage away from the absorption
field should be maintained.
Construction and Inspections
Prior to construction of the permitted system the engineer should be contacted by the contractor and owner
well in advance to provide adequate time to discuss the system components with the contractor, answer
questions, resolve any conflict issues and schedule inspection site visits based on construction progress.
County Regulations require that the Design Engineers of record perform site inspections of the permitted
system during construction and provide "As -Built" documentation of the installed system to the County
after construction is complete.
General Notes
1) All materials and installation practices shall conform to the Garfield County Individual Sewage
Disposal Regulation.
2) All sewer lines and distribution lines in the system shall be 4" Schedule 40 or SDR -35 PVC unless
specified otherwise on the plans.
3) Add a two-way clean out on the service lines from the house and detached bam.
4) The system shall be plumbed to distribution effluent into the trenches with equal distribution.
5) The contractor shall ensure that the concrete septic tank and sewer lines are watertight.
6) The trench area must be protected to prevent damage from vehicular or livestock traffic and must be
crowned to divert drainage runoff away from the trenches to minimize surface infiltration.
7) The leaching chambers shall be installed level in each trench. A splash plate shall be installed on the
trench bottom surface below the inlet in each trench to prevent scouring from the effluent. The top of
the backfill over the chambers shall be covered with filter fabric or other suitable pervious material to
prevent the migration of fines from the overlying topsoil Layer.

8) The trenches must have a minimum cover of 12 inches. A final cover of topsoil suitable for vegetation,
a minimum 4" deep, shall be placed from the top of the pervious cover layer to the finished surface
grade.
9) The absorption trenches must be sodded or covered with vegetative ground cover.
Our design and recommendations are based upon data supplied to us by others. If subsurface or site
conditions are found to be different from those presented in this report, we should be notified to evaluate
the effect it may have on the proposed OWS.
If you have any question or need any additional information, please call.

RE: As -Built OWS System, Fulbright/Mcvey Residence -Parcel 3, Lone Cottonwood Subdivision, County Road
229, Garfield County, CO
SE Job No. 24096.01
Dear Steve:
Pursuant to County Regulations, this letter provides documentation that the new OWS system recently installed is in general
compliance with the permitted design. Sopris Engineering has performed site visits to measure, inspect, and document the as
built conditions of the constructed system. The system was inspected prior to backfilling and after all installations were
completed. The as -built conditions and installation of the new OWS components is in compliance with the permitted design
specifications for the system.
The septic tank, distribution pipe, and absorption field were installed, with specified materials, in accordance with Garfield
County Regulations, the design presented in the Sopris Engineering Report and the design drawing, dated May 25, 2002. A 1500
gallon dual compartment septic tank was installed with 4" tee baffles and an effluent filter.
The absorption field was constructed with a total of 32 standard leaching chambers in a trench configuration with 4 trenches
containing 8 standard leaching chambers each. Each 50 feet long trench was installed level. Inspection ports were installed on
each comer end chamber. The chambers were installed in suitable soils consistent across the field. The chambers were
backfilled with native soil. Additional observations of the soils within the field were performed during construction indicating
that the soils are consistent with the descriptions in the geotechnical report. No ground water was encountered to a depth of 10
feet. The field has individual distribution lines to each trench from a concrete distribution box. The distribution box was -
installed level on compacted ground and is marked with a buried piece of rebar. The minimum setback distances have been
maintained.
OWS Operation and Maintenance
All components of the engineered OWS shall be inspected on a regular basis and be properly maintained. The re establishment
of vegetative cover over the field and responsibility for inspection and maintenance of the system will remain with the Lot
Owner or the owners representative. The owner shall periodically inspect the OWS and to perform all maintenance and repairs
as necessary to ensure that the system is in good operating condition and performing as designed.
The OWS should require minimal maintenance. Several factors influencing the need for maintenance include: actual wastewater
flows versus design flows, the volume of kitchen/domestic waste (excluding human waste and toilet paper), excessive household
chemicals and other toxic liquids. The tank, sanitary tees and effluent filter should be visually inspected bi-annually for
clogging debris, damage, leaks, or other potential problems. In general, for a properly utilized system, septic tanks should be
pumped and inspected every 2 - 4 years. The effluent filter should be cleaned every six months and at the time of pumping.
Absorption fields should be maintained with suitable vegetative cover and kept free of root invasive plants. Positive surface
drainage away from the absorption field should be maintained.
If you have any question or need any additional information, please call.
Sincerely,
SOPRIS ENGINEERING, LLC
