Permitted Construction / Details:
Install the OWTS exactly as depicted in the Kumar and Associates design dated January 20, 2020, stamped, signed,
and dated January 21, 2020 by David A. Young, PE. The system is design to serve a 5 bedroom residence.
The OWTS consists of a Valley Precast 1,500 gallon three-compartment septic tank (2,000 gallon total volume)
equipped with an Orenco PF3005 high head effluent pump, within an Orenco Biotube Vault, in the third compartment
with floats set to deliver approximately 27 gallons of effluent a maximum of 50 feet the soil treatment area (STA). The
STA is arranged in a bed configuration with two rows of 22 Infiltrator Quick4 Plus Standard chambers, for a total of
44 chambers, placed atop a sand filter mound. The mounded sand filter consists of a distribution cell 88 feet long
and 6 feet wide, over a basal area of imported secondary sand media, 88 feet long by 24 feet wide, placed over native
ground with vegetation removed and surface raked. The location of the water line had not been determined at the
time of design, be sure to stake it's location and maintain all setbacks and elevations.
Note: Gradation of the sand media use must be completed within one month prior to the installation and confirmed
with the design engineer. If the sand does not conform to secondary or preferred sand media requirements, it
cannot be used for the sand treatment media.
Contact Eagle County Environmental Health and the design engineer well in advance of requesting inspections prior
to backfilling any component of the OWTS. The design engineer is responsible for conducting all inspections
necessary to certify the installation and assure the functionality of the system. System certification, along with
photos and a record drawing is required to be submitted to and approved by, Eagle County Environmental Health
prior to the use of the system or occupancy of the dwelling.

INTRODUCTION
This report provides the results of an onsite wastewater treatment system (OWTS) design for the
proposed Hansbrough residence to be located on Lot 9, Block 5, Filing 34, Cordillera, 838
Granite Springs Trail, Eagle County, Colorado. The purpose of this report was to provide design
details for the OWTS in accordance with the 2018 Eagle County Onsite Wastewater Treatment
S\VWHP RHJXODWLRQV DQG WKH CRORUDGR DHSDUWPHQW RI PXEOLF HHDOWK DQG EQYLURQPHQW¶V
Regulation #43. The study was performed in accordance with our agreement to Pure Design
Studio dated November 7, 2019.
PROPOSED CONSTRUCTION
The residence will be a five-bedroom single-family structure with an attached garage located on
the lot as shown on Figure 1. The proposed OWTS soil treatment area (STA) will be located to
the north of the residence. Water service will be provided to the residence by the public water
supply from Granite Springs Trail near the northwest property corner. The location of the water
service line is not currently designed; however, we should be notified it¶s route encroaches on
the required 25 feet minimum setback from the STA.
If proposed construction is different than that described, we should be contacted to re-evaluate
our design recommendations.
SITE CONDITIONS
The lot was vacant at the time of field exploration and the ground surface appeared mostly
natural. The terrain at the proposed STA location slopes moderately down to the north at grades
of about 12 to 14%. The terrain is steep on the east side of the property, sloping down to the east
at grades of 25 to 35%. Vegetation on the lot consists primarily of grass and weeds. No surface
water features were observed in the near vicinity of the lot. We are not aware of any nearby
water wells.

Kumar & Associates, Inc. Project No. 19-7-676.02
SUBSURFACE CONDITIONS
The field exploration for the OWTS was conducted on November 15, 2019. Two profile pits
(Profile Pits 1 and 2) were excavated with a backhoe at the approximate locations shown on
Figure 1 to evaluate the subsurface conditions at the planned soil treatment area (STA) for the
OWTS. The pits were logged by a representative of Kumar & Associates. Logs of the profile
pits are provided below.
Log of Profile Pit 1
Depth USDA Classification
0-1¶ TOPSOIL; organic loam, firm, moist to slightly moist, dark brown.
1¶-8¶ CLAY; strong blocky structure, very stiff, slightly moist, reddish brown to light
brown.
x Bottom of pit @ 8 feet.
x No free water or redoximorphic features observed at time of pit excavation.
Log of Profile Pit 2
Depth USDA Classification
0-2¶ TOPSOIL; organic loam, firm, moist to slightly moist, dark brown.
2¶-8¶ CLAY; strong blocky structure, very stiff, slightly moist, brown.
x Disturbed bulk sample taken from 3 to 4 feet
x Bottom of pit @ 8 feet.
x No free water or redoximorphic features observed at time of pit excavation.
The soils encountered in the profile pits, below about 1 to 2 feet of organic topsoil, consisted of
Clay that extended down to the depths explored of 8 feet. Hydrometer and gradation analyses
were performed on a disturbed bulk sample of the soils from Profile Pit 2 from 3 to 4 feet depth
with the results provided on Figure 2. The tested sample (minus No. 10 size sieve fraction)
classified as Clay per the USDA system. No free water was encountered in the pits nor
indications of seasonal high groundwater were observed at the time of the pit excavations.
- 3 -
Kumar & Associates, Inc. Project No. 19-7-676.02
Based on the subsurface conditions and laboratory testing, the soils at the STA have been
classified as Type 4 per State regulations, which equates to a long-term acceptance rate (LTAR)
of 0.20 gallons per square foot per day for the Clay soils.
OWTS ANALYSIS
Based on the site conditions, the profile pit evaluations and our experience in the area, the clay
soils are expansive and tend to swell when wetted. Based on these considerations, we
recommend a mounded sand wastewater treatment system for proper treatment of the effluent.
The system will consist of chambers in a bed configuration overlying a sand filter placed on the
native ground surface. The STA will be sized five bedrooms (eight persons) using an LTAR of
0.8 gallons per square foot per day for importeG ³VHcondary sand PHGLD´. 7KH S7A EDVDO DUHD of
the sand will be sized for Soil Type 4 with an LTAR of 0.20 gallons per square foot per day.
The sewage will gravity flow from the residence to the septic tank for primary treatment and then
be pressured-dosed on a regular basis to the STA for dispersal and final treatment. Pressure
dosing is necessary for the sand treatment system.
The design location of the water supply well and water service line to the residence should take
into consideration for the required setbacks.
DESIGN RECOMMENDATIONS
The design recommendations presented below are based on the proposed construction, the site
and subsurface conditions encountered and our experience in the area. A layout of the proposed
OWTS components is provided on Figure 1. If conditions encountered during construction are
different than those that are described in this report, please contact us to re-evaluate our design
recommendations.

Kumar & Associates, Inc. Project No. 19-7-676.02
SOIL TREATMENT AREA
x The STA will consist of 2 rows of 22 Infiltrator Quick 4 Plus Standard chambers in a bed
configuration placed on imported secondary sand media. The sand media will be placed
on the native ground surface. A pressure distribution system will be used to disperse the
effluent to the chambers on a regular basis.
x The distribution cell was sized based on an LTAR of 0.80 gallons per square foot per day
for secondary sand media and a linear loading rate (LLR) of 4.8 gallons per linear foot.
The basal area was sized based on an LTAR of 0.20 gallons per square foot per day for
Soil Type 4 for the natural clay soils.
x A 30% reduction of the STA size was applied for use of Infiltrator chambers. The
minimum distribution cell dimensions are 6 feet wide by 87.5 feet long. The proposed
distribution cell will be 6 feet wide by 88 feet long (528 square feet).
x The minimum basal area of the mound is 88 feet long by 24 feet wide (2112 square feet).
x Soil treatment area calculations are shown on Figure 3.
x Vegetation should be removed and the ground surface scarified to at least 3´ deep prior to
the sand placement.
x Distribution lines, consisting of 1.5-inch diameter, Schedule 40 piping, with ǩ-inch
diameter orifice holes drilled at 4-foot centers near the center of the Infiltrators, should be
installed along the complete length of the chambers, see Figure 4. The distribution lines
should be suspended approximately 2 inches from the top surface of the infiltrators by
pipe ties. The orifice holes should face up toward the infiltrator surface above.
x A ǩ-inch hole should be drilled on the bottom of each end of the distribution pipe to
allow for complete drainage of the distribution line following pressure dosing. Install
splash plates below drain holes.
x The sand bed should be oriented along ground contours to minimize soil cover.
x Sand filter material should extend one foot horizontally from the perimeter of the
chamber bed and then be sloped at 3 horizontal to 1 vertical maximum in all directions.
x The sand filter media should meet the requirements of the current Eagle County OWTS
Regulations IRU ³VHFRQGDU\ VDQG PHGLD´. ASTM C33 concrete sand is suitable for the
filter media. A sample of the sand filter media should be obtained within one month prior
- 5 -
Kumar & Associates, Inc. Project No. 19-7-676.02
to installation of the system for gradation analyses testing by us or the gradation test
results of the sand provided to us for approval.
x The sand filter material shall be placed in lifts not exceeding 10 inches thick. Each lift
shall be track or bucket compacted until settlement ceases.
x A minimum of 10 inches and a maximum of 24 inches of cover soil should be placed
over the chambers.
x Backfill should be graded to deflect surface water away from the STA and should be
sloped at 3 horizontal to 1 vertical or flatter. This may require a swale along the up-slope
side of the STA.
x 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 STA as this
may damage the system piping.
x Four-inch diameter inspection ports should be installed vertically into the knockouts
provided in the Infiltrator end caps. Install ports at each corner of the bed. The
inspection port piping should be screwed into the top to the chambers and should not
extend down to the ground surface inside the chambers. The inspection ports should
extend at least 8 inches above the finished ground surface or be protected in a valve box
at finished grade.
x A plan view of the STA is presented on Figure 4 and a cross section of the STA is
presented on Figure 5.
x Cleanouts are required at the end of the distribution line. See Figure 6 for the cleanout
detail.
OWTS COMPONENTS
Recommended OWTS components provided below 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
x A 1,500 gallon, three-chamber septic tank (2,000 gallons total) will be used for primary
treatment and dosing to the STA. The first two chambers of the tank will be utilized for
- 6 -
Kumar & Associates, Inc. Project No. 19-7-676.02
treatment and settling, and the third chamber of the tank will contain the dosing pump. A
detail of the tank is provided as an attachment to the report.
x A submersible effluent pump enclosed in a Biotube Pump Vault will be installed in the
third chamber.
x The tank must be a minimum of five feet from the residence and from the STA. The tank
must be a minimum of 10 feet from any potable water supply lines.
x The tank must be set level. The excavation bottom must be free of large rocks or other
objects that could damage the tank during placement. A road base or gravel bedding
material may be needed to prevent tank damage during placement and act as a leveling
course.
x The tank lids must extend to final surface grade and made to be easily located.
x Install the tank with 2 feet minimum cover soil for frost protection. Maximum tank soil
cover is 4 feet.
Sewer Pipe
x The sewer line to the septic tank should not be less than the diameter of the building
drains and not less than 4 inches in diameter.
x The sewer pipe should have a rating of SDR35 or stronger.
x The sewer pipe should be sloped between 2% to 4% to help limit disturbance of solids in
the tank and the potential for 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.
x 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 and 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.
x The sewer pipe should be double encased with larger diameter Schedule 40 PVC pipe the
entire length of the sewer line if there is encroachment on the 50 feet setback to the well.
The encasing pipe should be sealed at both ends.
x The sewer pipe should be bedded in compacted ¾ inch road base or native soils provided
that the native soils contain no angular rocks or rocks larger than 2½ inches in diameter
- 7 -
Kumar & Associates, Inc. Project No. 19-7-676.02
to help prevent settlement of the pipe. Sags in the pipe could cause standing effluent to
freeze and damage the piping.
x Install cleanout pipes within 5 feet of the building foundation, where the sewer pipes
bend 90 degrees or more and at every 100 feet of sewer pipe.
x All 90-degree bends should be installed using a 90-degree long-sweep or by using two
45-degree elbows.
x The sewer line location shown on Figure 1 is considered conceptual. We assume that
there will be only one sewer line exiting the residence. It is the responsibility of the
owner/contractors 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 building.
Effluent Transport Piping
x The effluent transport pipe should be 1.5-inch diameter Schedule 40 piping sloped at a
2% minimum to drain to the STA manifold from the dose chamber.
x The effluent transport pipe should be bedded in compacted ¾ inch road base or native
soils provided that the native soils contain no angular rocks or rocks larger than 2½
inches in diameter to help prevent settlement of the pipe. Sags could cause standing
effluent to freeze and damage to the piping.
x 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 effluent pipe and insulation with at
least 2 inches of rigid foam insulation in these areas. If adequate cover soil is not
possible, we should re-evaluate the condition prior to installation.
x 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.
x All 90-degree bends should be installed using a 90 degree long-sweep or by using two
45-degree elbows.

Kumar & Associates, Inc. Project No. 19-7-676.02
Effluent Pumping System
x 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.
x The maximum effluent transport distance from the pump discharge to the STA estimated
to be 50 feet.
x The elevation difference from pump discharge to the STA is estimated to be about 2 feet.
x The pump should be enclosed in an Orenco Biotube Pump Vault for effluent filtering and
protection of the pump from vibration.
x An equivalent pump must be capable of operating at 20.0 gallons per minute at 10.4 feet
of total dynamic head. A pump performance curve is provided as an attachment to this
report.
x The floats should be set to provide a dose volume of approximately 110 gallons. To
achieve the desired dose volume, the XSSHU (³ON´) DQG ORZHr (³OFF´) IORDWV VKould be
set approximately 11 inches apart.
x The flow differential between the first and last orifices is estimated to be 2.0%.
x The high-ZDWHU DODUP IORDW VKRXOG EH SODFHG DSSUR[LPDWHO\ 3 LQFKHV DERYH WKH ³ON´
float in the dose tank. The high-water alarm must be wired on a separate electrical circuit
from the pump.
x A ǩ LQFK GLDPHWHU ZHep 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.
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.
- 9 -
Kumar & Associates, Inc. Project No. 19-7-676.02
OWTS HOUSEHOLD OPERATION
x Use of high efficiency water fixtures is recommended to decrease the hydraulic load on
the OWTS system.
x Fix plumbing leaks immediately as this may cause a hydraulic overload of the soil
absorption system.
x Do not irrigate the area on top of or directly upgradient of the soil absorption field as this
may cause a hydraulic overload.
x Do not dispose of household waste down 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.
x 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.
x 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.
x Limit the use of bleach as this may harm useful bacteria in the septic tank and soil
absorption system.
x 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 soil absorption system.
x 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.
OWTS MAINTENANCE
x Inspect the septic tank, pump, pump vault filter and STA at least annually for problems or
signs of failure.
x The filter should be cleaned annually by spray washing solids into the first chamber of
the septic tank.
x The septic tank should be pumped and cleaned about every 3 to 5 years depending on
- 10 -
Kumar & Associates, Inc. Project No. 19-7-676.02
use. Longer pumping intervals may increase the amount of solids that reach the STA,
which may shorten its life span.
x 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 a record drawing and certification of the OWTS construction (As-Built inspection). We
should be provided with at least 48-hour notice prior to the installer needing the inspections.
Prior to issuance of our certification letter, we require observation of all system components
prior to backfill. The As-Built inspection will include a pump test for the system. The number

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
and 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
have been appropriately interpreted. Significant design changes may require additional analysis
or modifications to our design.

Inspection Notes
The above-referenced permit has been inspected and finalized.
The Onsite Wastewater Treatment System (OWTS) was designed and installed to serve the five-bedroom residence on the
above property. Additional information about the maintenance of your septic system needs can be accessed through our website
links, provided on the Eagle County Environmental Health Department’s septic system resource page.
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 taproots, irrigation systems, and parking areas above the soil
treatment area can cause a 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. If you have any questions regarding this information,
please contact us at (970) 328-8755 and reference the OWTS septic permit number.

Received. Water line location is not shown, however, on inspection it was determined that the water line
was 10ft to the west of the soil treatment area within the setback. Photos confirm that setback
encroachment hazard was mitigated by encasing the waterline next to the STA and on 25' of either
side for a total of 60'.

Project No. 19-7-676.02
Permit No. OWTS-019078-2020
Subject: Certification of Onsite Wastewater Treatment System, Proposed Hansbrough
Residence, Lot 9, Block 5, Filing 34, Cordillera, 838 Granite Springs Trail, Eagle
County, Colorado
Dear Millie:
A representative of Kumar & Associates observed the installation of the Onsite Wastewater
Treatment System (OWTS) for the residence at the subject site as required by the Eagle County
Environmental Health Department. Our observations and recommendations are presented in this
report. The services are supplemental to Kumar & Associates agreement for professional
services to Pure Design Studio dated November 7, 2019.
We previously designed the OWTS for the residence as submitted in our report dated January 20,
2020, Project No. 19-7-676.02. The system was designed for five bedrooms. The OWTS was
installed by Defina Construction under Permit No. OWTS-019078-2020.
We performed our as-built evaluations on July 2, 2021 and April 13, 2022. The OWTS
components observed included: sewer line, cleanout, septic tank, effluent line, control panel and
soil treatment area (STA) and the locations of these components. The installation and locations
of the system components were verified as shown on Figure 1. Pictures of the OWTS
components made during the site visits are included with this report. The distance locations to
the septic tank shown on Figure 1 were made by taping.
On July 2, 2021, a sample of the secondary sand media was obtained and the results of gradation
analysis test are attached on Figure 2. On April 13, 2022, after power had been supplied to the
pump, a pump performance test was performed. We were unable to observe the pump pressure
due to snow cover on the STA.
The water line was encased throughout the area where it encroached on the setback to STA.
It is our opinion that the OWTS was installed in general conformance with the above referenced
design.

the driveway portion will be schedule 40 pipe, 4 feet deep and with ground insulation.
Is this acceptable and if so, can we handle as part of the As-Built, or do you need something other than this e-mail now?
Let us know. Thanks

Thank you, Dave. Yes, you can capture that in the record drawing/asbuilt and do not need a redesign. I will put this in the permit folder so it is recorded as well.
