Job No. 411 122A
Subject: As -Built Evaluation of On -site Wastewater Treatment System, Existing
Residence, Piney Valley Ranch, 23901 Highway 6, Eagle County,
Colorado
Dear Paul:
As requested, a representative of Hepworth-Pawlak Geotechnical observed the
installation of the new On -Site Wastewater Treatment System (OWTS) for the existing
three bedroom residence at the subject site. We previously designed the OWTS and
presented our recommendations in a report dated July 22, 2011, Job No. 411 122A. Our
observations and recommendations of the As -Built construction are presented in this
report.
We performed our As -Built site evaluation on September 2, 2011. The OWTS
components observed included: septic tank, effluent filter, cleanouts, Infiltrator chambers,
trench excavations, effluent pipe, distribution pipes, inspection ports, and the location of
these components.
The trench excavations for the infiltrators were observed to have cut depths ranging from
2 to 3 feet, allowing sufficient cover soil over the placed Infiltrator chambers. The trench
excavations maintained the minimum 6 foot separation between adjacent trench
sidewalls. The Infiltrator Quick 4 Standard chambers were observed to be installed level
on natural soils and will be backfilled with the on -site soils. The locations of the
infiltrators are shown on the attached Figure 1.
The 4-inch sewer line was installed from the existing residence to the septic tank inlet
with the proper slope to facilitate sewage disposal, with cleanouts properly installed
adjacent to the residence foundation and adjacent to the septic tank inlet.
A 1,000 gallon, two -chamber Valley Precast septic tank was installed level and equipped
with an effluent filter installed in the second chamber of the tank. The septic tank will be
equipped with risers and tank lids to allow access to the tank at finished grade; however,
this was not complete at the time of our site visit so observation of these components
could not be made.

Page 2
The 4-inch effluent line from the septic tank outlet to the Infiltrator chamber inlet within
the first trench was observed to be sloped properly to drain down to the absorption field.
The distribution lines from trench end to the beginning of the adjacent trench were sloped
properly to aid in the serial distribution of the effluent. The inspection ports were
installed correctly in the chamber knock -outs, one at the beginning and one at the end of
each trench.
The absorption field consisted of five trenches with the first four trenches containing nine
(9) Infiltrator Standard Quick-4 chambers and the last trench containing eleven (11)
chambers, for a total of forty-seven (47) chambers and 470 square feet of absorption area.
This configuration is slightly different than our design. The new trench configuration was
due to the proximity of the irrigation ditch located to the east of the installed absorption
field and to maintain the required 50 foot setback from the surface water feature.
It is our opinion that the OWTS meets the general intent of our July 22, 2011 design
report. The As -Built OWTS site plan is attached as Figure 1. An As -Built Photograph
Log of the system is also attached.
The observations and recommendations presented above are based on our visit and our
experience in the area. We make no warranty either express or implied. Alterations to
the system including amendments, changing components, backfill and site grading could
alter the operation and effectiveness of the OWTS.
Please feel free to contact us if you have any questions.
Sincerely,

PURPOSE AND SCOPE OF STUDY
As requested, Hepworth-Pawlak Geotechnical, Inc. has designed an Onsite Wastewater
Treatment System (OWTS) for the existing residence located at 23901 Highway,6, Piney
Valley Ranch near Wolcott in Eagle County, Colorado. The study was performed in
accordance with our agreement for professional services to Piney Valley Land Trust dated
May 25, 2011. The data obtained and our OWTS design recommendations based on the
existing residence conditions and the subsurface conditions percolation test results are
presented in this report.
SITE CONDITIONS
The existing residence has 3 bedrooms. The residence will be remodeled and updated.
The project site slopes slightly down to the south towards irrigated pasture. To the north
of the existing residence, the topography slopes steeply down to the south. Water service
will be provided to the residence by a natural spring located to the north of the residence.
SUBSURFACE CONDITIONS AND PERCOLATION TESTING
To evaluate the subsurface conditions at the proposed absorption field area, a Profile Pit
(PP) and three percolation test hole (P-1, P-2 and P-3) were excavated at the approximate
locations shown on Figure 1. The percolation testing was done to evaluate the infiltration
rate of the natural subsoils. The percolation test holes were hand dug in the bottom of the
shallow backhoe pits and soaked with water on June 1, 2011. The percolation testing was
performed on June 2, 2011.
A graphic log of the subsurface conditions encountered in the Profile Pit is provided on
Figure 2. The subsoils, below about 1 foot of topsoil, consisted of about 6 feet of medium
dense, clayey silty sand underlain by relatively dense, clayey sandy to very sandy gravel
with cobbles. No free water was encountered in the Profile Pit at the time of excavation.
Job No. 411 122A G( c&ech
-3-
The percolation test results, provided on Figure 3, indicate percolation rates of from about
13 to 20 minutes per inch with an average percolation rate of 18 minutes per inch. The
average percolation rate of 18 minutes per inch corresponds to a Long Term Acceptance
Rate (LTAR) of 0.72 gallons per square foot per day which will be used for sizing the
absorption area.
OWTS ANALYSIS
Based on the subsurface conditions encountered and the percolation test results, the tested
area is suitable for an OWTS utilizing Infiltrator Chambers and the shallow soils for the
treatment and dispersal of effluent. Our design is based LTAR of 0.72 gallons per square
foot per day. The ground surface at the absorption field site is relatively flat with a slight
slope down to the south. Required grading for the absorption field should be relatively
minor and primarily for the infiltrator trenches.
A site plan showing the proposed OWTS, existing residence and the minimum horizontal
setback distances of site features relative to the OWTS components is provided on Figure
1. The OWTS was designed for a total of three bedrooms. All materials and installation
should meet the requirements of the current Eagle County Land Use Onsite Wastewater
Treatment System Regulations.
SEPTIC TANK
A concrete 1,000 gallon, two -chamber, Valley Precast septic tank, or equivalent, will be
used for primary treatment of sewage from the residence. An effluent filter will be
installed on the outlet of the second chamber of the septic tank. Sewage will gravity feed
from the residence to the septic tank and effluent will be gravity fed to the absorption
area.
Job No. 411 122A GlgrAeCh
M
The tank should be placed level. If the septic tank access riser lids will be installed at
grade, with no backfill cover, then the lids should be insulated with foam insulation board
to provide frost protection. The sewer pipe inlet tee in the first chamber of the septic tank
should be installed beneath the access lid of the first chamber of the septic tank so that it
can be reached for service should it become clogged. The PVC handle on the effluent
filter should extend up to within reach of the second chamber access riser lid. This will
allow for easy access and maintenance of the filter. Approximately 2 feet of soil backfill
cover should be placed over the top of the septic tank to allow for easy access and frost
protection. For maintenance reasons, deep tank installations should be avoided and we
should be contacted to evaluate our design should it appear that a deep tank installation
involving more than 4 feet of backfill soil over the top of the tank may be required.
SEWER AND EFFLUENT PIPING
The sewer line from the proposed residence to the septic tank should not be less than the
diameter of the building drain and not less than 4 inches in diameter and will service all
levels of the existing residence. Soil backfill beneath the sewer pipe must be adequately
bedded and compacted to prevent settlement of the pipe. The sewer pipe should be
installed in landscape areas with at least 2 feet of soil backfill covering the pipe, or the
pipe should be insulated on the top and sides with 2 inch thick rigid foam insulation board
for frost protection. Beneath driving surfaces, we suggest Schedule 40 PVC sewer pipe
should be used and the pipe should be insulated if it will be installed with less than 4 feet
of backfill soil cover.
We suggest the use of Schedule 40 PVC pipe between the proposed residence and the
septic tank, though this is not required by local regulations. The portion of the sewer pipe
extending from 5 feet outside the building foundation should have a slope of at least 2%.
Cleanout pipes should be installed in the sewer line adjacent from the building
foundation, adjacent to the inlet of the septic tank, where the sewer pipe bends at 90
degrees or more, and at least one cleanout should be installed at least every 100 linear feet
of non -pressurized sewer or effluent pipe throughout its length. We recommend that a

straight section of pipe be installed between the residence foundation and the septic tank.
Any required 90 degree bends in the sewer pipe should be accomplished through the use
of a series of 45 degree smooth elbows or a 90 degree long sweep to help prevent
clogging of the pipe.
ABSORPTION AREA
The soil absorption area is designed to be 470 square feet and consist of five absorption
trenches containing 47 Infiltrator Quick 4 Standard chambers as shown on Figures 1 and
5. Each chamber was given 10 square feet of absorption area per Eagle County
regulations. A 50% reduction in the absorption field size was applied for Infiltrator
chambers in a trench configuration. The absorption area calculations are on Figure 4.
Four of the trenches will each contain 10 chambers and the fifth trench will contain 7
chambers, and will be combined in a serial distribution system. The absorption trenches
should be excavated to the approximate depths shown on Figure 6. The trench
excavations must follow the natural contours on -site and be level. Care must be taken
during installation to ensure that the soils exposed in the bottom and sidewalls of the
trench excavations are not compacted. Once the trench excavations are complete, the
trenches should be left open, if necessary, to allow the soils to air dry prior to placement
of the Infiltrator chambers and distribution pipes. After the soils have air dried, the
bottom and sidewalls of the excavations should be scarified prior to placement of the
chambers and piping.
The on -site soils can be used as backfill over the chambers and should be graded to
deflect surface water and precipitation away from the absorption area. We recommend
the soil backfill be re -vegetated as soon as possible with a mountain meadow grass mix or
suitable equivalent. It is important not to plant large vegetation or vegetation with
invasive roots in and around the absorption area and manifold piping as the roots may
damage piping.
JUU 1VU. 411 1LLA Gf. !&ech
w's
Combination air vent/inspection ports should be installed at each end of the absorption
trenches. The ports should be constructed of 4 inch diameter PVC pipe installed into the
knockouts provided on the tops of the Infiltrator chambers. The ports should extend a
minimum of 8 inches above the ground surface and should have ventilated removable
caps. Eagle County requires that the vent holes of the inspection ports be covered with
#16 fly-tite screen. The absorption area manifold and distribution piping layout and serial
trench connections are shown on Figure 5.
All materials used and installation methods should meet the requirements of the current
Eagle County Land Use Regulations for Onsite Wastewater Treatment Systems.
SUBSURFACE DRAINAGE
No free water was encountered in the profile pit when excavated on June 1, 2011 and it is
our opinion that a subsurface drain will not be required. If free water is encountered in
any excavations on the site we should be notified to evaluate the need for a subsurface
drain to protect the absorption area.
OWTS MAINTENANCE
The OWTS will require maintenance. The level of maintenance will vary with the
complexity of the system and water use habits of the users. We recommend that fat, oils,
bath oils, greases, paint, solids, water softener backwash solution, water from hot tubs and
other constituents that can clog and foul collection and disposal equipment are not
disposed of in the residence drains. The absorption area and any areas directly up
gradient should not be heavily watered by lawn irrigation systems or other means as the
soils may become hydraulically overloaded. The septic tank should be pumped whenever
the sludge occupies %3 of the liquid capacity of the first chamber of the septic tank. In
addition, the effluent filter should be checked for clogging at least once per year and
cleaned as necessary. We recommend that an operation and maintenance manual be
developed for the OWTS. The system should be operated and maintained as stipulated in
JOD 1VO. 411 122A _ Gf!ZAech
-7-
the manual. If you desire our services, we can prepare the operation and maintenance
manual for the system.
LIMITATIONS
This design has been conducted in accordance with generally accepted engineering
principles and practices in this area at this time. We make no warranty either express or
implied. The conclusions and recommendations submitted in this report are based upon
the data obtained from the profile pit and percolation test holes excavated at the locations
indicated on Figure 1 and to the depths shown, the proposed type of construction and our
experience in the area. Our findings include interpolation of the subsurface conditions
identified at the profile pit and 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 at once so re-
evaluation of the recommendations may be made.
Based on site reconnaissance, it is our opinion that the designed location of the OWTS
does not violate any setback requirements of the current Eagle County Environmental
Health Department's OWTS regulations. We recommend that the position of the OWTS
components, existing residence and setback requirements be verified in the field by a
Professional Land Surveyor licensed in the State of Colorado.
This report has been prepared for the exclusive use by our client for the OWTS design
submittal process. 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 OWTS construction to review and monitor the implementation of our
recommendations, and to verify that the recommendations have been appropriately
interpreted. Eagle County requires that an As -Built evaluation of engineered OWTS
designs be performed by the OWTS engineer. We should be contacted to perform
the OWTS As -Built evaluation at least 48 hours before you are ready for the
evaluation. You must obtain the required OWTS permit from Eagle County prior
JUD NO. 411 1LLA tech
to our As -Built inspection. Prior to evaluation, all OWTS components should be
installed including: effluent pipe, sewer pipe, septic tank, cleanouts, effluent filters,
Infiltrator chambers, and distribution and manifold piping. No components of the
OWTS should be backfilled prior to our performing the As -Built evaluation.
Please contact us for any necessary revisions or discussion after review of this report by
the Eagle County Environmental Health Department. If you have any questions, or if we
may be of further assistance, please let us know.
