RE: AS -BUILT On -site Wastewater System 4, Ranch Parcel Facility, Ranch Hand Bunkhouse, on the
Peace Ranch, Eagle County Colorado
Sopris Engineering, LLC Job No. 24055.01
Eagle County Permit Nos.
Dear Gentleman:
Pursuant to Eagle County regulations, this letter and attached drawings provide documentation that the new
On -site Wastewater Systems (OWS Systems 4) recently installed is in general compliance with the
permitted design. Sopris Engineering has performed site visits to inspect and document the as built
conditions of the constructed OWS. The as -built size and configuration of the completed system
components were installed in accordance with the design plan drawings. The OWS components have
been installed, utilizing specified materials, in accordance with Eagle County Regulations, the design
presented in the Sopris Engineering Report and the design drawing, dated July 7, 2006, and revised July 7,
2006. The Parcel improvements associated with OWS-4 include the construction of a 4-bedroom
residential structure.
As -Built Conditions
System-4
System-4 handles the effluent from the 4-bedroom ranch hand bunkhouse and includes a 1500-gallon
septic tank and a serial distribution trench absorption system located on gently sloping terrain down
gradient from the residential structure. The system meets required setbacks and is installed as indicated on
the plan.
A double compartment, 1500-gallon concrete septic tank system has been installed with an inlet sanitary
tee and an effluent filter in the outlet sanitary tee. The gravity sewer line was installed at a 2% slope from
the buildings to the tank. The tank is accessible for maintenance within the landscape area adjacent to the
structure off the parking area. Effluent discharges to a new 750 square foot soil absorption trench system
configured for serial distribution. Three trenches were installed level and each has an inspection port on
the serial end of each trench. The bottom elevation of each trench has an average depth of 2.5 to 3 feet to
the infiltrative surface below the finished grade. Adjacent trenches have a minimum horizontal separation

of 7 feet. The total as -built trench absorption area is 750 SF; utilizing 75 Quick-4 Infiltrator leaching
chambers installed in-3 serial trenches 100' long. The gravity sewer line was installed at a 2% slope from
the buildings to the tank. The tank is accessible for maintenance within the landscape area adjacent to the
structure off the parking area. The exposed soils after grubbing were suitable and consistent across the
field. The chambers were backfilled with excavated material. A minimum of 12 to 24 inches of backfill
was placed over the chambers to the finish sloped grades that have been shaped to provide drainage away
from the trenches. Appropriate grading around the down gradient side of the field was completed with
approximate side slopes at 3:1 to daylight. 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. The as -built locations are delineated on the attached plans.
ISDS Operation and Maintenance
The systems shall be inspected on a regular basis and be properly maintained. The systems and
responsibility for repair and maintenance of the systems will remain with the Owner.
The onsite systems 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, harsh detergents (Tide Ultra,
Oxy Clean) and other toxic liquids. The tanks, absorption fields and effluent filters and pump assemblies
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 3 - 6 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 fields should be maintained.
We recommend that SE conduct a follow up inspection and performance check next spring to insure the
components are operating and functioning as designed in accordance with the design specifications.
If you have any question or need any additional information, please call.

RE: Ranch Hand Bunk House, Proposed On -site Wastewater System No. 4, for the Peace Ranch, Eagle
County Colorado
Sopris Engineering, LLC Job No. 24055.01
Dear Tim:
Pursuant to your request, this letter/report presents our findings in regard to the feasibility and design for an
engineered Onsite Wastewater System (OWS) at the above referenced Site. This design is based on our
evaluation of the site conditions with information provided by you for use in supporting your application to
Eagle County. Our recommendations are in accordance with Eagle County and the State of Colorado
ISDS Regulations. Eagle 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.
conchisinnc
Based on our findings we believe that the design and installation of an approved OWS is feasible in
accordance with the Regulations of Eagle County and the State of Colorado. We recommend that a new
1500 gallon septic tank be installed that will discharge effluent to a 750 square foot soil absorption trench
system. The soil absorption system can be installed in natural soils and will be located within the general
area down gradient of the proposed house, as delineated on the attached plan. The system meets all
required setbacks and will 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 in the vicinity of East Taylor Creek, approximately 3.5 miles North of the
Frying Pan River on Forest Service Road 510, in Eagle County, Colorado. The site is situated in Section
30, T 7 S, R 85 W of the 6t" P.M. The Site comprises approximately 72 acres. The site is bounded on the
south, east and west by adjacent parcel of the Peace Ranch and Forest Service property.
Existing Site Conditions
The site is located on undeveloped, mountainous range and pasture land. The site has a moderate slopes
(15%-35%) toward the southwest toward the main fork of Taylor Creek. The existing ground surface in
the proposed absorption field area has an approximate slope of 20%. The site is covered with native
grasses, weeds and Aspen trees. Domestic water will be supplied by a domestic well and water system
onsite. There are no wells within 100 feet of the general vicinity of the proposed absorption field.

Proposed Site Conditions
It is our understanding that you intend to construct a 4-bedroom bunk house. The maximum number of
rooms to be utilized as bedrooms in the future is 4. Therefore the system is designed to handle the flow
from a 4-bedroom house. The proposed improvements will include a new OWS, bunk house and driveway
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 on May 25, 2006 by Hepworth-Pawlak
Geotechnical, Inc (HP). The results are attached in the HP report dated July 6, 2006, Job Number 104 354.
The subsoil encountered at the site consists of 2 '/2 to 3 '/2 feet of topsoil overlying sandy, silty clay with
gravel and cobbles to a depth of 9 feet. Groundwater was not encountered in the profile test boring.
Percolation testing utilized three test holes, which yielded similar absorption rates. The fastest measured
rate was 20 minutes per inch and the slowest measured rate was 30 minutes per inch. The average
percolation rate is 27 minutes per inch and should be suitable for a conventional absorption system.
An additional profile hole may need to be excavated for visual inspection by the Eagle County
Environmental Health Specialist and the Engineer prior to installation of the absorption field. The
evaluations and inspections may result in modifications to the design that may include field size revisions
and possible soil replacement in select areas if needed. Sufficient notice to Eagle County and the Engineer
by the owner/contractor needs to be made in order to schedule the site visit.
Design Criteria
The absorption field is designed based on utilizing the suitable native soil for treatment in trenches.
Based on the reported percolation rate and observations of the percolation holes and review of the
geotechnical information we have designed a system that will treat the calculated quantity of effluent with
native soils utilizing the Long Term Acceptance Rate (LTAR) for the native soils. The treated effluent will
then be absorbed into the natural soils across the bottom area and a portion of the sidewall areas of the
trench excavation. . The LTAR is based on the interpolation of absorption rates corresponding to the
average percolation rate. The wastewater application rates are from Table 7-2, EPA Design Manual,
Onsite Wastewater Treatment and Disposal Systems.
The absorption field is designed based on utilizing the suitable native soil for treatment in trenches.
However if some areas in the proposed trenches need soil replacement to mitigate the presence of
concentrated cobbles and or boulders, we recommend the placement of suitable soil or concrete sand, as
needed, to a level grade with the rest of the trench.

Desian Flow
Proposed residence is a 4-bedroom house. The design flow is calculated as follows:
Residence unit - 4 bedrooms @ 2 person /bedroom = 8 person
From the Eagle County I. S. D. S. Regulation;
Max. Design flow (Qd) = # of people x 1.5(avg. flow) gal/person/day.
Gallons per day for the subject house = 75 gal/person/day
Qd= 8*75*1.5 =900 Qa� 1/day
Septic Tank Design
Residence
Q = 8*75*1.5 =900
Volume (V) of tank = Design Flow * 1.25
(30 hour retention time)
V = 900 gal/day * 1.25 = 1125
Use one 1500-gallon septic tank
Soil Absorption System Desian
The percolation test indicated the slowest percolation rate of 30 minutes per inch and an average rate of 27
minutes per inch. Therefore this range is used to estimate a loading rate for the soil and size the absorption
area required for treatment utilizing native soils.
A = Absorption Area
Long Term Acceptance Rate method (LTAR):
LTAR loading rate for soil with perc rate between
16 and 30 min/inch = 0.6 gal/S.F./day
A=Q/LTAR = 900/0.60 = 1500 sq. ft.
We recommend using a gravelless leaching chamber absorption trench system. The county allows up to a
50% adjustment in absorption area if gravelless leaching chambers are used in suitable soils. The
equivalent Absorption area per the Infiltrator Quick-4 leaching chamber unit is 10 S.F.
Apply a 50% reduction for utilizing gravelless infiltration chambers in a trench configuration.
A = 1500 sq. ft. x 0.50 = 750 sq. ft. (Apply a 50% reduction)
Assume 10 square feet per chamber: 750 sq.ft. = 75 chambers Use 75 chambers

We recommend using a trench system composed of 3 trenches up to 100 feet long and 3 foot wide,
containing 25, Infiltrator Quick-4 chamber units in 3 serial trenches respectively. Excavate absorption
trenches to accommodate a minimum 750 S.F. of interior surface area. Pursuant to previous discussions
with Eagle County Environmental Health, serial distribution is recommended.
Distribution
An effluent filter shall be installed on the outlet of the secondary chamber in the septic tank. The filter
should be inspected every six months. Maintenance shall include cleaning the filter as needed and after
periodic pumping of the tank.
We recommend that the trenches be connected with the inlet pipe coming into the inlet port of the first
serial trench chamber. The effluent flow will run the length of the first trench discharge through the outlet
pipe connected to the end chamber. The outlet pipe will run across the minimum 6' separation distance to
the second serial trench and connect to the inlet port of the first chamber. The flow will run the length of
the second trench and connect the same way to the first chamber in the third trench. Each trench will be
constructed level with successive trenches installed at a lower elevation than the preceding trench to
accommodate drainage in the distribution pipes and surface grades. Each trench shall be constructed not to
exceed a maximum depth of 3 feet. The method allows for the sloped terrain, provides increased longevity
of the system and allows for maintenance and/or partial reconstruction if needed. An inspection port
should be installed on the top cut out port on the serial end chamber in each trench. This will allow for
checking the performance of the system over time.
The gravity sewer line from the house to the tank shall be SDR-35 PVC or schedule 40 PVC pipe bedded
and backfilled with class 6 aggregate base material. The minimum bedding depth shall be 4" below the
pipe with a minimum bedding width of 12" in the trench. The backfill shall be placed to a minimum 4"
above the top of the pipe across a minimum 12" width. All SDR-35 PVC or schedule 40 PVC Pipe
installed under landscaped areas shall be bedded in accordance with the above bedding specifications.
SDR-26 PVC pipe may be installed in landscaped areas over suitable soil and backfilled with material free
of rocks in excess of 3" diameter and/or partially bedded and backfilled with class 6 aggregate base course
as needed.
All other specifications in the design plan and report shall be followed. Contractor should review any
conditions on the issued permit and coordinate with the engineer regarding construction of the system.

ISDS Operation and Maintenance
The system shall be inspected on a regular basis and be properly maintained. The system and
responsibility for repair and maintenance of the system will remain with the Lot Owner.
The onsite 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, strong laundary detergents and
other toxic liquids. The tank, absorption field and effluent filter 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 4 - 8 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. The Regulations further require site inspections and approval by the County
Environmental Health Department of the exposed components of the system prior to backfilling.
Therefore the County Environmental Health Department should also be contacted and notified of the
construction schedule.
General Notes
1) All materials and installation practices shall conform to the Eagle 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 line from the proposed house.
4) The system shall be plumbed to distribution effluent into the trenches with serial 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 infiltration chambers shall be installed level in each trench. A splash plate shall be installed on the
trench bottom surface below the inlet in each serial trench to prevent scouring from the effluent or an
appropriate chamber end plate may be used 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.
