Permitted Construction / Details:
Install the OWTS exactly as depicted on the HP Geotech design report and drawings dated July 13, 2015,
date stamped and signed on July 14, 2015 by Chad M. Bringle, PE.
System consists of the installation of a 2,000 gallon two compartment Valley Precast septic tank followed
by a 500 gallon Valley Precast 500T-HH pump vault equipped with an Orenco AF 3005 effluent pump in an
Orenco Biotube pump vault; with 1500 square feet of absorption area credit (prior to adjustments for
using chambers and pressure dosing) via the installation of 72 Infiltrator Quick 4 Plus Standard chambers
arranged in four shallow trenches with 18 chambers per trench. An Orenco V6404 Automatic Distributing
Valve (ADV) will be installed at the high point in the effluent line which will deliver alternating doses of
roughly 100 gallons to each trench sequentially. Specifications on the ADV must be provided by the
design engineer.
Do not install in wet weather or frozen ground. The existing tank must be abandoned in accordance with
WQCC Regulation 43.9 (C.). Access to grade is required for all tank access points as well as the ADV.
Contact the design engineer at least 48 hours in advance to conduct any and all inspections necessary to
certify the system and prepare the appropriate documentation that goes along with it. System
certification along with as-built drawings, photos and documentation of tank abandonment are required
prior to the use of the new system.

RE: Final approval of septic permit OWTS-10-15-13604; Tax parcel #193920402001;
Property location: 1794 Eby Creek Rd, Eagle area
Mr. Patriacca:
This letter is to inform you that the above-referenced septic permit has been inspected and
finalized. This permit was approved and sized for a total capacity for 4 bedrooms. Additional
information about the maintenance your septic system needs can be accessed through web site
links provided on the Environmental Health Department’s home page at
http://www.eaglecounty.us/envHealth/
Be aware that changes in the use of your property or alterations of your building may
require commensurate changes to, or relocation of, your septic system. Landscape features,
trees with tap roots, irrigation systems and parking areas above the drain field can cause
premature system failure. It is equally important that you notice and immediately repair
dripping faucets and hissing toilets as this will certainly cause the system to fail. By
following a few simple guidelines, like avoiding grease or other additives down the drain and
making sure your septic tank is on a pumping schedule, your system has been designed to
last for many years.
If you have any questions regarding this information, please contact us at (970) 328-8755 and
reference the OWTS septic permit number.
Sincerely,
Terri Vroman

Project No. 16-9-107
Subject: As -Built Evaluation of Onsite Wastewater Treatment System, Existing Residence
and Garage, Parcel 2, Kelly Subdivision, 1794 Eby Creek Road, Eagle County,
Colorado
Dear Mr. Patriacca:
H-P KUMAR observed the installation of the Onsite Wastewater Treatment System (OWTS) for
the existing residence and garage at the subject property as required by the Eagle County
Environmental Health Department. Hepworth-Pawlak Geotechnical, Inc. previously designed an
OWTS for the subject site and presented our recommendations in a report dated July 13, 2015
Job No. 415 117A. Our observations and recommendations are presented in the following
paragraphs.
We performed our As -Built site evaluation on April 27, May 31 and June 2, 2016. The OWTS
components observed include: sewer pipe, cleanouts, septic tank, dose tank, effluent pump and
pump operation, effluent transport pipe, automatic distribution valve and valve cycling, soil
treatment area and the locations of components. The installation and locations of system
components were verified as shown on Figure 1. The effluent pump was tested prior to the
system being connected to the existing residence and garage. A 2,000 gallon, two chamber
Front Range Precast septic tank and a 500 gallon single chamber Front Range Precast dose
tank were used instead of the equivalent Valley Precast tanks recommended in our design.
Photographs of the OWTS installation are provided in the attached Photograph Log.
It is our opinion that the OWTS was installed in general conformance with our July 13, 2015
design. The observations and recommendations presented above are based on our site
observations and our experience in the area. We make no warranty either express or implied.

Alterations to the system or improper backfill and site grading could affect the operation and
effectiveness of the OWTS.

The purpose of this report was to provide design details for an OWTS in accordance with the
2014 Eagle County Onsite Wastewater Treatment System Regulations and the Colorado
Department of Health and Environment's Regulation #43.
PROPOSED CONSTRUCTION
There is an existing residence and detached garage on the property. Eagle County records
indicate that the residence is five bedrooms. The garage has a %2 bath with no living area, but the
upper level is currently used as office space. The OWTS soil treatment area (STA) will be
located south of the residence and garage as shown on Figure 1. The OWTS was designed for a
of six bedrooms. If proposed construction is different than that described, we should
be contacted to re-evaluate our design recommendations.
f.YY � D[K� ►11 �3�G�
There is an existing residence and detached garage on the property. The ground surface in the
vicinity of the proposed OWTS soil treatment area (STA) is steeply to moderately sloping to the
west. Vegetation consists of grasses and brush. Eby Creek is located to the west of the proposed
OWTS. A 50 feet setback from the edge of water is required from septic tanks, sewer and
effluent lines and the STA.
Water service is provided to the residence and garage by the existing well located west of the
residence. There is also an abandoned well location southeast of the residence. No other wells
were identified in the near vicinity.
The existing septic tank is located north of the existing garage. The tank must be abandoned per
Eagle County regulations. Typically, tanks are pumped dry then the bottom and lids of the tanks
are crushed and the void is backfilled with onsite soil.

SUBSURFACI•; CONDITIONS
The field exploration was conducted by H-P Geotech on June 9, 2015. Two profile pits (Profile
Pits 1 and 2) and were excavated at the approximate locations shown on Figure I to evaluate the
subsurface conditions. Logs of the profile pits are provided below. The soils encountered
consisted of about 6 to 12 inches of topsoil overlying silt loam with gravel (Soil Type 2) to the
maximum depth explored, 7 feet. Logs of the profile pits are provided below. A gradation
analysis was performed on a disturbed bulk sample from the assumed infiltrative surface of the
soils from Profile Pit I with the results provided as Figure 2.

OWTS ANALYSIS
Based on the site and subsurface conditions encountered, a conventional STA is suitable for the
proposed construction. The sewage will gravity flow to the septic tank for primary treatment,
then effluent will flow to the dose tank where it is pressure dosed to the STA for fmal treatment.
The STA will consist of a four trenches with Infiltrator chambers. Effluent doses will be
alternated to the four trenches by an automatic distributing valve (ADV).

DESIGN RECOMIVVI[ENDATIONS
The design recommendations presented below are based on the proposed construction, the site
and subsurface conditions encountered and our experience in the area. If conditions encountered
during construction are different than those that are described in this report, please contact us and
we will re-evaluate our design recommendations.
• The treatment system will consist of four trenches with 18 Infiltrator Quick 4 Plus
Standard chambers in each trench.
• The STA was sized based on an LTAR of 0.6 gallons per square feet per day. Soil
treatment area calculations are shown on Figure 3.
• The base and sidewalls of the trench excavation should be scarified prior to chamber
installation.
• A minimum of 12 inches and a maximum of 32 inches of cover soil should be placed over
the chambers.
• Backfill should be graded to deflect surface water away from the STA and should be
sloped at 3 Horizontal:l Vertical maximum.
• Disturbed soil should be re -vegetated as soon as possible with a native grass mix. No
trees, shrubs or other plants with deep roots should be planted on or near the absorption
area as this may damage the system piping or chambers.
• Four inch diameter inspection ports should be installed vertically into the knockouts in
the end caps as each end of each trench. The piping should not extend to the soil surface
and should be screwed in place to prevent slippage. The inspection ports should extend at
least 8 inches above the finished ground surface or be protected in a valve box at finished
grade. The portion that lies within the gravel should be perforated.
• A plan view of the STA is presented on Figure 4 and a cross section of the STA is
presented on Figure 5.
• Cleanouts must be installed in each of the distribution lines in the STA. A typical
cleanout detail is provided as Figure 6.

OWTS COMPONENTS
Recommended OW IS components provided are based on our design details and our experience
with the specific component manufacturers. Equivalent components may be feasible but need to
be approved by us prior to construction.
Septic Tank
• A 25000 gallon, two chamber Valley Precast septic is proposed for primary treatment.
The septic tank will be followed by a 500 gallon dose tank equipped with a submersible
effluent pump. A copy of the tank details are provided as attachments to this report.
• The tanks must be set level. The excavation bottom must be free of large rocks or other
objects that could damage the tank during placement. A gravel road base bedding
material may be necessary to prevent tank damage during placement and act as a leveling
course.
• Install tank with 2 feet minimum cover soil for frost protection. Maximum tank soil
cover depth is 4 feet.
• The septic and dose lids must extend to fmal surface grade and made to be easily located.
Sewer Pipe
• The sewer line from the residence and garage to the septic tank should not be less than the
diameter of the building drain and not less than 4 inches in diameter.
• The sewer pipe should have a rating of SDR35 or better.
• The sewer pipe should be sloped between 2% to 4% to help limit disturbance of solids in
the tank and potential sewage bypass of the first chamber of the tank. If a steeper slope is
needed, this can be accomplished with vertical step-downs in the sewer line.
• A minimum 36 inches of cover soil should be provided over the sewer pipe. Paved areas,
patios or other areas without vegetative cover may be more susceptible to frost. We
recommend 4o inches of soil cover over the sewer pipe in these areas and the pipe be
insulated on top and sides with 2 inch thick blue foam insulation board. If adequate soil
cover is not possible, we should be contacted for re-evaluation prior to installation.
• The sewer pipe should be bedded in compacted 3/4 inch road base or native soils provided
that the native soils contain no angular rocks or rocks larger than 2'/2 inches in diameter to
help prevent settlement of the pipe. Sags could cause standing effluent to freeze and
damage piping.
Job No. 415 117A Gr�teCh
-5-
• Install cleanout pipes within 5 feet of the building foundation, where the sewer pipe bends
90 degrees or more and every 100 feet of sewer pipe.
• A1190 degree bends should be installed using a 90 degree long -sweep or by using two 45
degree elbows.
• The sewer line location shown on Figure 1 is considered conceptual. We assume that
there will be only one sewer line exiting the residence and one line exiting the garage. It
is the responsibility of the owner to locate all sewer line exit locations and connections to
the septic tank. We should be notified if there are other sewer lines exiting the residence.
Effluent Transport Piping
• 1.5 inch diameter Schedule 40 effluent transport piping should be sloped at 2%minimum
to drain back from the ADV to the dose tank and from the ADV to the manifolds in each
trench. The ADV must be the high point of the system.
• The effluent transport pipe should be bedded in compacted'/4 inch road base or native
soils provided that the native soils contain no angular rocks or rocks larger than 21A2 inches
in diameter to help prevent settlement of the pipe. Sags could cause standing effluent to
freeze and damage piping.
• 18 inches minimum of cover soil should be provided over the effluent transport pipe.
Paved areas, patios or other areas without vegetative cover may be more susceptible to
frost. We recommend 48 inches of soil cover over the sewer pipe in these areas. If
adequate cover soil is not possible the effluent pipe should be insulated on top and sides
with 2 inch thick foam insulation board and the design engineer should re-evaluate soil
cover prior to installation.
• The effluent pipe should be double encased with larger diameter Schedule 40 PVC pipe
underneath driveway surfaces and be provided with at least 48 inches of soil cover and be
insulated on top and sides with 2 inch thick foam insulation board.
• A1190 degree bends should be installed using a 90 degree long -sweep or by using two 45
degree elbows.
Effluent Pumping System
• An Orenco PF3005, 115 volt, submersible effluent pump with a 1.25 inch diameter
discharge assembly, or equivalent, will be required for effluent pumping.
Job No. 415 1 17A Ge�tGCh
MIS
The maximum effluent transport distance from the pump discharge to the ADV is
estimated to be 138 feet. The distance from the ADV to the STA manifolds is estimated
to be an additional 33 feet.
• The elevation difference from pump discharge to the STA manifold is estimated to be 15
feet.
• The pump should be enclosed in an Orenco Biotube Pump Vault for effluent filtering and
protection of the pump from vibration.
• An equivalent pump must be capable of operating at 12.9 gallons per minute at 26.0 feet
of total dynamic head. A pump performance curve is provided as an attachment to this
report.
• The floats should be set to provide a dose volume of approximately 112 gallons. The
actual dose volume will be about 99 gallons assuming 13 gallons of drainback in the
transport line. To achieve the desired dose volume the upper ("ON") and lower ("OFF")
floats should be set approximately 11 inches apart.
• The flow differential between the first and last orifices is estimated to be 2.7%.
• The high water alarm float should be placed approximately 3 inches above the "ON" float
in the dose tank. The high water alarm must be wired on a separate electrical circuit from
the pump.
• A '/8 inch diameter weep hole should be drilled in the effluent transport line prior to
exiting the dose tank so the transport line can drain after each pumping cycle.
Automatic Distributing Valve
• An Orenco V6404 Automatic Distributing Valve (ADV) will be used to alternate doses to
the four STA trenches.
• The ADV must be installed level and must be the high point in the system.
• The ADV should be installed in a sprinkler box, or equivalent, such that it is serviceable
and protected from freezing. We recommend the ADV be equipped with heat tape for
additional frost protection during winter months.
• We recommend the ground surface be graded away from the ADV in all directions.
Improper surface drainage could cause standing water to freeze and damage the valve
and/or piping.
• The valve has clear sections of pipe that should be inspected at least annually to ensure
that it is alternating doses to each trench.
Job No. 415 117A �t!eCh
OWTS OPERATION AND MAINTENANCE
The OWTS will require periodic inspection and maintenance to function properly. A properly
designed, installed and maintained system can greatly increase its lifespan. The level of
maintenance will vary depending on the complexity of the system and water use habits of the
residents. We recommend that an OWTS Operation and Maintenance (O&M) Manual be
developed. Depending on the complexity of the system a contract with an OWTS maintenance
provider may be prudent. Below are some basic recommendations for the OWTS O&M.
OWTS HOUSEHOLD OPERATION
• Use of high efficiency water fixtures is recommended to decrease the hydraulic load on
the OWTS system.
• Fix plumbing leaks immediately as this may cause a hydraulic overload of the STA.
• Do not irrigate the area on top of or directly upgradient of the STA as this may cause a
hydraulic overload.
• Do not dispose of household waste down household drains as this may clog or damage
OWTS components. Examples of household waste includes: dental floss, cotton swabs,
coffee grounds, paper towels, feminine products and many other kitchen and bath items.
• Use of kitchen garbage disposals is not recommended. If a garbage disposal is utilized,
kitchen wastewater should be screened thoroughly. Many kitchen solids are not
decomposed in the septic tank and may cause increased tank pumping frequency.
• Do not dispose of household chemicals, greases, oils, paints, hot tub water or water
softener backwash in household drains. A separate drywell, if feasible, may be necessary
for hot tub water or water softener backwash disposal.
• Limit the use of bleach as this may harm useful bacteria in the septic tank and STA.
• Liquid dishwasher and clothes washer detergent is recommended for households served
by an OWTS. Clay substances used as fillers in powder detergents may result in clogging
of the STA.
• The effluent in septic tanks can freeze during extended periods of non-use in cold
weather. We recommend that a tank heater be installed in this system to help prevent
freezing.
lob No. 415 117A ���
-8-
CPa _MWOoM►M MAP
• Inspect the septic tank, dose tank, Biotube pump vault, AD and soil treatment area at
least annually for problems or signs of failure.
• The pump vault filter should be cleaned annually by spray washing solids into the first
chamber of the septic tank.
• Septic tank should be pumped and cleaned every 3 to 5 years depending on use. Longer
pumping intervals may increase the amount of solids that reach the soil absorption area,
which may shorten its life span.
• Pumping of the septic tank should take place when the level of the sludge and scum layers
combined take up 25 to 33% of the capacity of the first chamber of the tank.
OWTS CONSTRUCTION OBSERVATION
The Eagle County Environmental Health Department requires that the designer of the system
provide an As -Built certification of the OWTS construction. We should be providedpwith at least
48 hour notice prior to the installer needing the As -Built inspections. Prior to issuance of our
certification letter, we require observation of all system components prior to backfill. The number
of site visits required for the inspection will depend on the installer's construction schedule.
LIMITATIONS
We have conducted this design in accordance with generally accepted engineering principles and
practices in this area at this time. We make no warranty either expressed or implied. The
recommendations provided in this report are based on the site conditions, profile pit evaluations,
soil texture analysis, the proposed construction and our experience in the area. Variations in the
subsurface conditions may not become evident until excavation is performed. If conditions
encountered during construction appear different from those described in this report, we should be
notified so that re-evaluation of the recommendations may be made.
This report has been prepared for the exclusive use by our client for design purposes. We are not
responsible for technical interpretations by others of our information. As the project evolves, we
should provide continued consultation and field services during construction to review and
monitor the implementation of our recommendations, and to verify that the recommendations
Job No. 415 117A Ge"c�tGCh
-9-
have been appropriately interpreted. Significant design changes may require additional analysis
or modifications to our design.
It is our opinion that the designed location of the OWTS components does not violate any setback
requirements of the current Eagle County Regulations. Below is a table of common minimum
horizontal setbacks to OWTS components. Refer to the Eagle County Regulations for a complete
list of required setbacks. We recommend the OWTS components be surveyed by a Professional
Colorado Land Surveyor and verified by H-P Geotech prior to the system permitting.
