Installing an OWTS without a permit
Ray Merry <ray. merry @eag lecounty. us> Wed, Aug 3, 2016 at 5:38 PM

Cc: #environment <environment@eaglecounty.us>, "W.Y. Construction" <bmtike@centurytel.net>
Kenny,
As we discussed earlier today, you installed an On -site Wastewater Treatment System (OWTS) at 49 Kicking Horse Trail
without having a valid permit in -hand. I'm sending this email as a courtesy to stress the importance of making sure that
you always have a valid OWTS permit before installing a system.
The sanctions that you expose WY Construction to when installing an OWTS without a permit can lead to both being
fined as well as having the installer's license revoked for a year.
We are disappointed when we are placed in the awkward position of having to consider such sanctions with any of our
licensed contractors and ask that you always make certain that you always have a valid OWTS permit prior to doing any
OWTS work in the future.
It is very important that you read the permit language carefully to be sure the design that is approved for installation
matches the design that you're working from and that the plans are followed exactly as depicted on the design. Be aware
that often times, there are other requirements included in the permit that require special attention or additional actions
that must be completed in order to get final approval.
As a reminder, any time you come across issues that tempt you to digress from the design in any way, please be sure
to contact the design engineer to discuss the changes and receive permission from us, in writing, before implementing
any changes to the approved design. Permission to proceed may come in the form of an email or may require a permit
amendment.
Feel free to contact me with any concerns or questions and please "reply all" with the date on the HP Geotech design
report as well as the date it was stamped so we know what is installed matches what we reviewed.

RE: Final approval of septic permit OWTS-9-14-11540; Tax parcel #210717201007;
Property location: 49 Kicking Horse Trail, Cordillera area
Mr. Millsap:
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 5 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

Subject: As -Built Evaluation of Onsite Wastewater Treatment System, Proposed Milsap
Residence, Lot 7. Filing 33, The Territories at Cordillera, 49 Kicking Horse Trail,
Eagle County, Colorado
Dear Brennen:
As requested, representatives of H-P/Kumar observed the installation of Onsite Wastewater
Treatment System (OWTS) for the proposed residence at the subject property as required by the
Eagle County Environmental Health Department. This report summarizes our observations and
recommendations. The services were supplemental to Hepworth-Pawlak Geotechnical's (now
H-P/Kumar) agreement for professional services to Scott S. Turnipseed, AIA dated June 17.
2014.
Hepworth-Pawlak Geotechnical previously designed the OWTS for the subject residence and
presented our recommendations in a report dated August 21, 2014, Job No. 114 241 B. The
system was designed for six bedrooms.
We performed an initial As -Built evaluation on October 23 and 28, 2015. Additional As -Built
evaluations were performed on August 10 and September 22, 2016. The OWTS was installed by
W.Y. Construction under permit number 9-14-11540. The OWTS components observed
included: sewer pipe, cleanouts, septic tank, dose tank, effluent pump and pump performance,
effluent transport pipe, soil treatment area including sand placement for the mounded system,
and the Iocations of these components. The position of the sewer pipe, septic tank, effluent
transport pipe and soil treatment area were modified some from our design. The sewer pipe was
constructed to exit the west side of the residence just north of the chimney, and the septic tank
location was adjusted accordingly. The effluent transport pipe was reconfigured to enter the
south side of the soil treatment area instead of the north side. The soil treatment area was angled
to the northwest to align better with ground contours. All modifications were verbally approved
by us prior to installation and will not change the overall performance of the design.

The installation and locations of system components were verified as shown on Figure 1.
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 the August 21, 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.
Please feel free to contact us if you have any questions regarding this letter.

INTRODUCTION AND OVERVIEW
This report provides the results of an onsite wastewater treatment system (OWTS) design
for the proposed CTF Ranch residence to be located on Lot 7, Filing 33, The Territories at
Cordillera, 2728 Kicking Horse Trail, near Edwards, Eagle County, Colorado. The report
summarizes the site and subsurface conditions, and provides design details for the OWTS
in accordance with the 2014 Eagle County Onsite Wastewater Treatment System
Regulations and the Colorado Department of Public Health and Environment's
Regulation #43. The services were performed as part of our agreement for professional
services to Scott Turnipseed AIA, dated June 17, 2014.
BACKGROUND INFORMATION
Hepworth-Pawlak Geotechnical, Inc. (HP Geotech) previously prepared a subsoil study
for foundation design for the property and submitted our findings in a report dated July
25, 2014, Job No. 114 241A. The report included a review of the site conditions,
evaluation of the subsurface conditions and percolation testing which are the basis for our
OWTS design.
PROPOSED CONSTRUCTION
The residence will be a six bedroom residence with an attached garage located on the
property as shown on Figure 1. The proposed soil treatment area for the septic system is
planned to the southwest of the residence. Two out buildings are also proposed. We
understand that the out buildings will not have plumbing. If proposed construction is
different than described, we should be contacted to re-evaluate our design
recommendations
SITE CONDITIONS
The lot was vacant at the time of our field exploration and the ground surface appeared
mostly natural. The terrain is a low knoll with strong slopes down to the northwest and
west. Slope grades range from 8 to 15%. The slope grades become moderately steep on
Job No. 114 241 B Gt~gteCh
-2-
the order of 20% further to the west in the area of the proposed soil treatment area.
Vegetation consisted of grasses, weeds and sagebrush.
SURFACE WATER AND WETLANDS
There are two small ponds and apparent wetlands in the southwest corner of the building
envelope over 200 feet from the proposed soil treatment area.
WELLS
The proposed well for the property is shown on Figure 1 adjacent to the driveway
between the proposed residence and Out Building 1. A minimum 100 feet setback is
required from the soil treatment area to the well and a 50 feet minimum setback is
required from the septic tanks and sewer line to the well.
SUBSURFACE INVESTIGATION
The field exploration for the project was conducted on July 10, 2014. Two Profile Pits
(Profile Pits I and 2) and three percolation test holes (P-1, P-2 and P-3) were excavated at
the approximate locations shown on Figure I to evaluate the subsurface conditions. Logs
of the Profile Pits are provided below. The subsoils encountered consisted of 6 inches of
topsoil overlying strong -blocky Clay/Silty Clay Loam with subangular basalt rock
fragments to the depth explored, 7Y2 feet.

No free water or indications of seasonally shallow groundwater were observed in the pits
and the subsoils were generally moist. The results of a gradation/hydrometer analyses
performed on bulk sample of the subsoils from our previous study is attached as Figure 5.
PERCOLATION TESTING
Percolation tests were performed in the three test holes by HP Geotech on July 11, 2014.
The percolation rates obtained ranged from about 45 to 180 minutes per inch (mpi) with
an average percolation rate of about 95 mpi. Percolation test procedures outlined in
Regulation #43 were not utilized and the results were only used for comparison of the
USDA soil type.
OWTS ANALYSIS
Based on the profile pit soils, the infiltrative surface of the soil treatment area (STA) will
be located in strong -blocky Clay/Silty Clay Loam. A Long -Term Acceptance Rate
(LTAR) of 0.2 gallons per square foot per was estimated based Table 10-1 of Regulation
#43. A two (2) feet thick mounded sand filter will be used; therefore, the design LTAR
can be increased to 0.3 gallons per square foot per day for Treatment Level 2 at the
infiltrative surface (basal area).
Based on the soil conditions encountered, a mounded sand filter treatment system will be
required for the site. A Long -Term Acceptance Rate (LTAR) of 0.3 gallons per square
foot per day was used for sizing of the Clay Loam/Silty Clay Loam soils for the basal
area of the mounded sand filter, which assumes Treatment Level 2. Sewage will be
collected in the septic tank for primary treatment then gravity flow to a dosing tank where
it will be pumped to the mounded soil treatment area (STA) for disposal. A 2 feet
maximum cut depth will be allowed for the soil treatment area construction.
DESIGN RECOMMENDATIONS
The recommendations presented below are based on the site and subsurface conditions
encountered and our experience in the area. If soil or site conditions encountered during
construction are different than those that are described in this report please contact us and
we will re-evaluate our recommendations.
Job No. 114 241B G49tech

SOIL TREATMENT AREA
• The soil treatment absorption field will consist of an aggregate bed that is 75 feet
long by 12 feet wide constructed over a 2 feet thick mounded sand filter. The
aggregate area was sized based on an LTAR for concrete sand of 1.0 gallons per
square feet per day.
• A basal sand area of 3,000 square feet will be required based on an LTAR of 0.3
gallons per square foot per day. Due to the sloping site, only the basal sand area
directly beneath and downgradient of the aggregate bed has been included in the
usable basal area. An area of 40 feet wide by 75 feet long has been assumed for
the mounded soil treatment area. The soil treatment area calculations are
presented on Figure 2.
• Concrete sand is suitable for construction of the mounded sand filter.
• Absorption area aggregate will be a minimum of 1 foot thick. See Figure 4 for the
aggregate specifications.
• A minimum of 12 inches and a maximum of 36 inches of cover soil should be
placed over the soil treatment area aggregate. A layer of 2 ounce/ydz (or stronger)
filter fabric should be placed over aggregate prior to backfill. Mirafr 160N or
equivalent is recommended.
• Backfill should be graded to deflect surface water away from the absorption area
and should be sloped at 3H:1 V maximum.
• Disturbed soil should be re -vegetated immediately 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 piping.
• Four inch diameter inspection ports should be installed at each corner and in the
center of the aggregate beds. The inspection port piping should extend to the base
of aggregate. The portion of the pipe that lies within the aggregate should be
perforated. The inspection ports should extent at least 8 inches above the finished
ground surface or be protected in a valve box at finished grade.
• A plan view of the absorption area is presented as Figure 3 and a cross section of
the absorption area is presented as Figure 4.

OWTS COMPONENTS
Recommended OWTS components were based on our design details and our experience
with the specific component manufacturers. Equivalent components may be used if
desired; however, they must meet our minimum recommendations and should be
approved by the design engineer.
Septic and Dose Tank
• A 2,000 gallon, two chamber Valley Precast septic tank is proposed for primary
treatment of sewage from the residence. The septic tank will be followed by a 500
gallon Valley Precast dose tank equipped with a submersible effluent pump.
Pump specifications are provided in the Effluent Pumping System section of this
report. A copy of the tank details are attached to this report after the figures.
• The tanks must be set level. The excavation must be free of large rocks or other
objects that could damage the tank during placement. A gravel base course
bedding material may be necessary to prevent tank damage during placement and
act as a leveling course.
• Install tanks with 2 feet minimum cover soil for frost protection. Maximum tank
burial depth is 4 feet.
• The septic and dose tank lids must extend to finished grade.
Sewer Pipe
• The sewer line from the existing residence 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.
• Sewer pipe should be sloped at 2% minimum from the residence to the septic tank
except for the last 10 feet, which should be sloped at 4% maximum (2%
minimum) to help limit disturbance of solids in the tank.
• A minimum 36 inches of cover soil should be provided over the sewer pipe.
Paved areas, patios or other areas without vegetative cover maybe more
susceptible to frost. We recommend 48 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.
Job No. 114 241 B G-M Bch
M
• The sewer pipe should be bedded in compacted 3/ 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.
• Install cleanout pipes within 5 feet of building foundation, where the sewer pipe
bends 90 degrees or more and every 100 feet of sewer pipe.
• All 90 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 existing residence. It is the
responsibility of the owner to locate all sewer line exit locations and connections
to the septic tank.
Effluent Transport Piping
• The 1.25 inch diameter Schedule 40 effluent transport piping should be sloped at
2% minimum to drain from the dose tank to the absorption area manifold.
• The effluent transport pipe should be bedded in compacted'/< 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.
• A minimum 18 inches 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.
• All 90 degree bends should be installed using a 90 degree long -sweep or by using
two 45 degree elbows.
Job No. 114 241B G "'Ptech
-7-
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 the effluent
pumping.
• The maximum effluent transport distance from the pump discharge to the
treatment area manifold is estimated to be 75 feet.
• The elevation difference from pump discharge to the dose tank is estimated to be
10 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 26.1 gallons per minute at
26.8 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 95 gallons.
To achieve the desired dose volume the upper ("ON") and lower ("OFF") floats
should be set approximately 9 % inches apart.
• The high water alarm float should be placed approximately 3 inches above the
"ON" float in the dose tank.
• A /s inch diameter weep hole should be drilled in the effluent transport line prior
to exiting the dose chamber so the transport line can drain after each pumping
cycle.
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 the lifespan of
the OWTS. The level of maintenance will vary with the complexity of the system and
water use habits of the residents. We recommend that an Operation and Maintenance
(O&M) Manual be developed for the system to ensure that it is properly maintained.
Depending on the complexity of the system a contract with an OWTS maintenance
provider may also be prudent. Below are some basic recommendations for the O&M.
Job No. 114 241B GtVgtech
OWTS HOUSEHOLD OPERATION
• Use of high efficiency water fixtures is recommended to decrease the hydraulic
load on the OWTS.
• Fix plumbing leaks immediately as this may cause a hydraulic overload of the soil
absorption system.
• Do not irrigate the area on top of or directly upgradient of the soil absorption
system 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 that should not be
disposed of in drains include: 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 for households served by an
OWTS. 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 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 soil
absorption system.
• 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 soils absorption system.
• The water in septic tanks can freeze during extended periods of non-use. We
recommend that second homeowners install a tank heater to help prevent freezing.
OWTS MAINTENANCE
• Inspect the septic tank, dose tank, pump vault 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.
Job No. 114 241B Gec�tech
-9-
• 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 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 septic tank.
OWTS CONSTRUCTION OBSERVATION
The Eagle County Environmental Health Department requires that the designer provide
an As -Built certification of the OWTS construction. We should be provided with at least
48 hour notice prior to the installer needing inspection. Prior to issuance of our
certification letter, we require observation of all system components prior to backfill. The
number of site visits required will be dependent on the installer's construction schedule.
LIMITATIONS
We have conducted this study in accordance with generally accepted engineering
principles and practices in this area at this time. We make no warranty either expressed
or implied. The conclusions and recommendations submitted in this report are based
upon the site conditions, data obtained from the profile pits, percolation test holes, soil
texture analysis, the proposed type of 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 have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein.
Job No. 114 241B C3Mech

It is our opinion that the designed location of the OWTS 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 permitting.

Subject: As-Built Evaluation of Onsite Wastewater Treatment System, Proposed Milsap
Residence, Lot 7, Filing 33, The Territories at Cordillera, 49 Kicking Horse Trail,
Eagle County, Colorado
Dear Brennen:
As requested, representatives of H-P/Kumar observed the installation of the Onsite Wastewater
Treatment System (OWTS) for the proposed residence at the subject property as required by the
Eagle County Environmental Health Department. This report summarizes our observations and
recommendations. The services were supplemental to Hepworth-Pawlak Geotechnical’s (now
H-P/Kumar) agreement for professional services to Scott S. Turnipseed, AIA dated June 17,
2014.
Hepworth-Pawlak Geotechnical previously designed the OWTS for the subject residence and
presented our recommendations in a report dated August 21, 2014, Job No. 114 241B. The
system was designed for six bedrooms.
We performed an initial As-Built evaluation on October 23 and 28, 2015. Additional As-Built
evaluations were performed on August 10 and September 22, 2016. The OWTS was installed by
W.Y. Construction under Eagle County permit number 9-14-11540. The OWTS components
observed included: sewer pipe, cleanouts, septic tank, dose tank, effluent pump and pump
performance, effluent transport pipe, soil treatment area including sand placement for the
mounded system, and the locations of these components. The position of the sewer pipe, septic
tank, effluent transport pipe and soil treatment area were modified some from our design. The
sewer pipe was constructed to exit the west side of the residence just north of the chimney, and
the septic tank location was adjusted accordingly. The soil treatment area was angled to the
northwest to align better with ground contours. All modifications were verbally approved by us
prior to installation and will not change the overall performance of the design. Pump
performance calculations were verified and no modifications to the design were required.
Scott S. Turnipseed
October 3, 2016
Page 2
Project No. 16-7-288
The installation and locations of system components were verified as shown on Figure 1.
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 the August 21, 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.
Please feel free to contact us if you have any questions regarding this letter.
Respectfully,
