RE: McDonald Residence -Proposed ISDS System, Lot 4, Bumguardner Subdivision,
Garfield County, CO
SE Job No. 22052.01
Dear Dan:
Pursuant to your request, attached herewith is a letter/report presenting our findings in regard to the
feasibility and design for an Individual Sewage Disposal System (ISDS) at 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 ISDS 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 ISDS system is feasible in
accordance with the Regulations of Garfield Co1¥1tY and the State of Colorado. We recommend that a
new 1000 gallon septic tank be installed that will discharge effluent to a 435 square foot soil absorption
trench system. The soil absorption system can be installed in natural soils and will be located within the
septic envelope 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
The subject site is located on Lot 4 in the Bumguardner Subdivision on County Road 312, approximately 2
miles south of the Colorado River up Divide Creek, in Garfield County, Colorado. The site is situated in
Section 30, T 39 N, R 107 W of the 6'h P.M. The Site comprises approximately 5.3 acres. The site is
bounded on the north, east and west by agricultural lands with scattered single-family homes and out
buildings and on the south by an embankment down to Divide Creek and County Road 312.
Existing Site Conditions
The site is located on irrigated agricultural land. The site has a gentle slope (3%-5%) toward the north-
northwest to Divide Creek. The existing ground surface in the proposed septic area has an approximate
slope of 5%. The site is covered with pasture grasses, with sagebrush and oak brush on the fringe near the
embankment. Domestic water will be supplied by an onsite well. There are no wells within 100' of the
general vicinity of the absorption field.

It is our understanding that you intend to construct a 2-bedroom home with a detached barn to include a
future one-bedroom unit with a full bath. The maximum number of rooms to be utilized as bedrooms in
the two structures is 3. Efficient water saving fixtures will be installed to reduce average usage rates.
The proposed improvements will include a new ISDS system with appropriate site grading. The new
structure is to be generally located as shown on the plan.
Subsurface Conditions
Attached herewith are the results of the subsurface geotechnical investigation conducted on April 2, 2002
by Yeh and Associates, Inc. The report is dated April 16, 2002. The subsoil encountered at the site
consists of 1/2 foot of topsoil overlying clayey sand to the profile pit depths of 9 feet. Groundwater was
not encountered in the profile pits.
In addition, attached are the results of the subsurface percolation tests conducted on April 12, 2002 by
Sopris Engineering, LLC. The subsoil encountered in the percolation test holes is similar to the test pits
and consists of 1/2 foot of topsoil overlying silty clayey sand with occasional gravels below 3 feet.
Groundwater was not observed in the test pit excavations. Percolation testing, utilizing three test holes,
was performed to determine an average percolation rate. The fastest measured rate was 20 minutes per
inch and the slowest measured rate was 60 minutes per inch. The average percolation rate is 37 minutes
per inch and is suitable for a conventional absorption system.
Design Criteria
The design flow is calculated as follows:
Single family home -equivalent 3 bedroom population @ 2 person /bedroom = 6 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 6-person population
Qd = 6*75*1.5* =675 gal/day
Septic Tank Design
Based on Design Flow Qd.
Qd = 675 gal/day
Volume (V) of tank = Design Flow * 1.25
(30 hour retention time)
V = 675 gal/day • 1.25 days = 844 gallons
Use one 1000-gallon dual compartment concrete septic tank

The field is sized by using the standard absorption area equation. A soil absorption trench system,
utilizing graveness 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. The average percolation rate is 37 minutes/inch. We are using 40 minutes/inch for design.
Based upon the design percolation rate, the standard absorption area equation is:
A (SF)= Qd *(t) 1-1 : where
5
A= Area; Qd =Design flow (gal/day)
t = time in minutes
This design calculation results in a recommended minimum absorption area:
A= 675 *(40) 1> = 854 sq. ft.
5
Apply a 50% reduction for utilizing gravelless infiltration chambers in a trench configuration.
854 x 0.5 = 427 sq. ft.
Use 427 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: 427 sq.ft. = 27.5 chambers Use 28-30 chambers
15.5 sq.ft/chamber(50%)
We recommend using a trench system composed of 3 trenches 63 feet long and 3 foot wide, containing 10
standard leaching chamber units in each trench. Or 4 trenches 44 feet long and 3 foot wide, containing 7
standarc! leaching chamber units in each trench. Excavate absorption trenches to accommodate a minimum
430 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 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 distribution pipes
will incorporate perforated risers in the distribution box to insure equal distribution into each discharge
pipe. The discharge pipes will connect to the head of each chamber row. A splash plate shall be installed
on the trench bottom below each trench inlet to prevent scouring. An inspection port should be installed
on the top mid-point cut out at the end chamber in each trench and the 2 comer end head chambers. This
will allow for checking the performance of the system over time.
ISDS Operation and Maintenance
Dan & Lisa McDonald
SE Job No. 22052.01
May22, 2002
Page4
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
retain the services of qualified personnel to inspect the ISDS and to perform maintenance and repairs
necessary to ensure that the system is in good operating condition. 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 and maintenance
procedure be performed every 6 months.
The ISDS 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 barn.
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 ISDS. If the County Environmental Health Department requests
changes or modifications to this design, we should be contacted to evaluate the effect on the ISDS.
If you have any question or need any additional information, please call.
