Onsite Wastewater Treatment System (OWTS) Installation Observations
2-Bedroom Residence
760 Forest Drive
Eagle County, Colorado
Permit # OTWS-018682-2020
Shawn,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on October 16, 2020 for the subject property. Hagist Excavation installed the system.
The OWTS design is based on 2-bedrooms. An average daily wastewater flow of 300 GPD was be
used.
Setbacks from the well were verified as 82’ 4” to the septic tank and 115’ 3” to the soil treatment area
(STA).
A double-sweep clean out was installed on the 4-inch diameter SDR 35 sewer line between the house
and the new septic tank. This sewer line has a minimum 2% grade to the septic tank. A new, 1000-
gallon, two-compartment Valley Precast concrete septic tank with an Orenco® Biotube Pump Vault and an
Orenco® PF3005 pump has been installed in the second compartment of the septic tank. The floats were
set to dose approximately 70 gallons each pump cycle, allowing approximately 7 gallons for drain back after
each pump cycle. The control panel for the pump is located within line of sight of the septic tank. We
recommended Valley Precast out of Buena Vista be contracted for start-up of the pumping system.
Effluent is pressure dosed through a 1.5-inch diameter pump line to an Orenco® automatic distributing valve
(ADV), model 6402. This pump line has a minimum 1% grade for proper drain back into the tank after each
pump cycle. The ADV has been placed a high point in the system and was placed in an insulated riser with
access from grade.
Effluent is dosed to two over-excavated, 6’ x 32’ unlined sand filters with a minimum of 3-feet of sand filter
material (Secondary Sand). Laterals used to disperse the effluent are surrounded by washed coarse
screened gravel. The manifolds are 1.5-inches in diameter. Laterals are 1.5-inches in diameter with 5/32-
inch diameter orifice holes facing down, spaced 2-feet on center. Each 1.5-inch diameter lateral end in a
sweeping ell facing up with a ball valve for flushing. A soil separation fabric has been placed over the
gravel layer followed by approximately 1-foot of topsoil or other suitable soil able to support vegetative
growth.
The OWTS was generally installed according to specifications. This observation is not a guarantee of
workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are
made to the OWTS in the future. Any additional OWTS construction must be according to the county
regulations.
LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must
have documented and demonstrated knowledge of the requirements and regulations of the county in
which they are working. The quality of the installation is dependent of the expertise of the installer, soil
type, and weather conditions.
Please call with questions.

Subsurface Investigation and Onsite Wastewater Treatment System Design
2-Bedroom Residence
760 Forest Drive
Eagle County, Colorado
Shawn,
ALL SERVICE septic, LLC performed a subsurface investigation and completed an onsite wastewater
treatment system (OWTS) design for the subject residence. The 35.03-acre property is located outside of
Carbondale, in an area where OWTSs and wells are necessary. Original design documents dated
January 18, 2019 should be discarded and replaced with these dated May 11, 2020. The proposed
development has changed from 4-bedrooms to 2-bedrooms.
Legal Description: COULTER CREEK RANCHES Lot: 2
BK-0659 PG-0148 MAP 01-11-95
BK-0704 PG-0363 MAP 09-04-96
Parcel ID: 2189-271-01-003
SITE CONDITIONS The property is currently undeveloped with the exception of the driveway and well. A 2-bedroom
residence is proposed.
The property is slopes to the east toward East Coulter Creek. The area of the proposed STA has a slope
of approximately 5% to the east and is covered with native vegetation including sage.
The residence is served by a private well, located to the south of the residence. This well is located
greater than 50-feet from the proposed septic tank and greater than 100-feet from the proposed STA.
Table 1 describes the minimum required setback of OWTS components to physical features on the
property compared to approximate, proposed setback distances.

SUBSURFACE The subsurface was investigated on September 6, 2018 by digging two soil profile test pit excavations (Test
Pits). A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1
The materials encountered in the Test Pit #1 consisted of dark brown topsoil to 2.5-feet, underlain by
fracture rock to a maximum depth explored of 5.0-feet. The fractured rock is able to be over-excavated.
No groundwater was encountered.
The materials encountered in Test Pit #2 were consistent with those encountered in Test Pit #1 with
difficult digging conditions below 2-feet. The test pit was excavated to a maximum depth of 4.0-feet. No
groundwater was encountered.
The base soils and topsoil were examined, and the sample formed a ball and a ribbon approximately 1-
inch in length before breaking. Soil structure shape was granular, soil structure grade was moderate,
and consistence was loose to friable. Soil texture was more smooth than gritty.
STA sizing is based on Soil Type 2, Silt Loam with moderate structure. Content of fractured rock below
2-feet is greater than 65% and requires an over-excavated sand filter with a minimum of 3-feet of sand
filter material. A larger machine will be utilized to excavate the STA than was used to excavate the
test pits.
Soil Type is classified as R-0 (Soil Type 2 with greater than 65%, design including 3-feet
secondary sand filter material). A long term acceptance rate (LTAR) of 0.8 gallons per square foot
will be used to design the OWTS.
Backfill from Test Pit #1 rock below 2-feet

DESIGN SPECIFICATIONS
Design Calculations:
Average Design Flow = 75 GPD x 2 people/bedroom x 2 Bedrooms = 300 GPD
LTAR = 0.8 GPD/SF (Soil Type 2, TL3), Secondary Sand
300 GPD / 0.8 GPD/SF x 1.0 (pressure dosed over-excavated sand filter) x 1.0 (pipe and gravel) = 375 SF
The new OWTS design is based on 2-bedrooms. An average daily wastewater flow of 300 GPD will be
used.
For the purposes of this OWTS design, Benchmark Elevation has been established as 100’, the elevation
of the sewer line exiting the residence. ALL SERVICE septic, LLC should be notified of any
discrepancies or problems with grade elevations of proposed components during installation of the
OWTS.
OWTS Component Minimum Elevation
Primary Tank Inlet Invert Min. 99’
Automatic Distributing Valve Min. 101’ (High point of system)
Infiltrative Surface Min. 100’
A double-sweep clean out should be installed on the 4-inch diameter SDR 35 sewer line between the
house and the new septic tank. This sewer line must have a minimum 2% grade to the septic tank. A
new, 1000-gallon, two-compartment Valley Precast concrete septic tank with an Orenco® Biotube Pump
Vault and an Orenco® PF3005 pump must be installed in the second compartment of the septic tank. The
floats should be set to dose approximately 70 gallons each pump cycle, allowing approximately 7 gallons for
drain back after each pump cycle. The control panel for the pump must be located within line of sight of the
septic tank. We recommend Valley Precast out of Buena Vista be contracted for start-up of the pumping
system.
Effluent will be pressure dosed through a 1.5-inch diameter pump line to an Orenco® automatic distributing
valve (ADV), model 6402. This pump line must have a minimum 1% grade for proper drain back into the
tank after each pump cycle. The ADV must be placed a high point in the system and be placed in an
insulated riser with access from grade. Screened rock must be placed below the ADV to support the ADV
and to assure the clear pipes existing the ADV remain visible for future inspection and maintenance.
Topography was not available on the site plan, so location of the ADV must be verified at the high
point of the system.
Page 5
Effluent will be dosed to two over-excavated, 6’ x 32’ unlined sand filters with a minimum of 3-feet of sand
filter material (Secondary Sand). Sand filter material must be clean, coarse sand, all passing a screen
having four meshes to the inch. The sand must have an effective size between 0.15 and 0.60 mm. The
uniformity coefficient must be 7.0 or less. Material meeting ASTM 33, for concrete sand, with three percent
or less fines passing 200 mesh sieve may be used. A gradation of the sand media must be provided.
There must be at least 6-feet of undisturbed soil between the beds.
Laterals used to disperse the effluent must be surrounded by washed coarse screened gravel or crushed
stone. All of the gravel or stone must pass a 2 ½-inch screen and must be retained on a ¾-inch screen. The
manifold must be 1.5-inches in diameter. Laterals must be 1.5-inches in diameter with 5/32-inch diameter
orifice holes facing down, spaced 2-feet on center. Laterals must start 2-feet from the sidewall of the sand
filter creating a 2-foot separation between the laterals. Each 1.5-inch diameter lateral must end in a
sweeping ell facing up with a ball valve for flushing. A soil separation fabric should be placed over the
gravel layer followed by approximately 1-foot of topsoil or other suitable soil able to support vegetative
growth.
The component manufacturers are typical of applications used by contractors and engineers in this area.
Alternatives may be considered or recommended by contacting our office. Construction must be
according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided
by Eagle County Environmental Health Department, and this design.
REVEGETATION REQUIREMENTS
An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire
disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing
characteristics (but without taproots), provides a maximum transpiration rate, and competes well with
successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be placed over
the area. Until vegetation is reestablished, erosion and sediment control measures shall be implemented
and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation
cover.
OPERATION INFORMATION AND MAINTENANCE
The property owner shall be responsible for the operation and maintenance of each OWTS servicing the
property. The property owner is responsible for maintaining service contracts for manufactured units,
alternating STAs, and any other components needing maintenance.
Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials
should be placed on the backfilled STA. Livestock should not graze on the STA. Plumbing fixtures should be
checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or
leaky faucet can discharge hundreds of gallons of water a day and harm a STA.
If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned
annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be
flushed annually, or as needed.
The homeowner should pump the septic tank every two years, or as needed gauged by measurement of
solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not
be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener
should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS.
Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste
only.
Page 6
ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of
freezing. The pump shall have an audible and visual alarm notification in the event of excessively high
water conditions and shall be connected to a control breaker separate from the high water alarm breaker
and from any other control system circuits. The pump system shall have a switch so the pump can be
manually operated.
Excavation equipment must not drive in excavation of the STA due to the potential to compact soil.
Extensions should be placed on all septic tank components to allow access to them from existing grade.
Backfill over the STA must be uniform and granular with no material greater than minus 3-inch.
INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be
performed before backfill, after placement of OWTS components. Septic tanks, distribution devices,
pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic,
LLC should be notified 48 hours in advance to observe the installation.
LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions
described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be
according to the county regulations. Requirements not specified in this report must follow applicable
county regulations. The contractor should have documented and demonstrated knowledge of the
requirements and regulations of the county in which they are working. Licensing of Systems Contractors
may be required by county regulation.
Please call with questions.

Pump Curves
Pump curves, such as those shown here, can help you determine
the best pump for your system. Pump curves show the relationship
between flow (gpm or L/sec) and pressure (TDH), providing a graphical
representation of a pump’s performance range. Pumps perform best
at their nominal flow rate, measured in gpm or L/sec.

Using a Pump Curve
A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow (gpm or L/sec) and pressure
(total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal
flow rate — the value, measured in gpm, expressed by the first two numerals in an Orenco pump nomenclature. The graphs in this section show
optimal pump operation ranges with a solid line. Flow flow rates outside of these ranges are shown with a dashed line. For the most accurate
pump specification, use Orenco’s PumpSelect™ software.

Introduction
Orenco’s automatic distributing valve assemblies, pressurized with small high-head effluent
pumps, are useful for distributing effluent to multiple zones. These zones can be segments
of sand filter manifolds, drainfields, or other effluent distribution systems. Distributing
valve assemblies can substantially simplify the design and installation of a distribution sys-
tem and reduce installation costs. This is particularly true where a distributing valve assem-
bly is used instead of multiple pumps and/or electrically operated valves. Additionally, a
reduction in long term operation and maintenance costs is realized due to a reduced size
and/or number of pumps. More even distribution can be achieved on sloping sites by zoning
laterals at equal elevations. This eliminates drainback to lower lines and the unequal distrib-
ution of effluent that occurs at the beginning of a cycle.
Valve Operation
The valve itself has only a few moving parts, requires no electricity, and alternates automati-
cally each cycle. Refer to Figure 1 for the following valve operation description. The flow
of the incoming effluent forces the rubber flap disk 1 to seat against the valve bottom 2.
The opening 3 in the rubber flap disk aligns with an opening in the valve bottom to allow
flow to only one valve outlet. The stem 4 houses a stainless steel spring which pushes the
rubber flap disk away from the valve bottom after the flow of effluent stops. The stem acts
as a cam follower and rotates the rubber flap disk as the stem is raised and lowered through
the cam 5. The force from the flow of effluent pushes the stem down through the cam and
the stainless steel spring pushes the stem back up through the cam when the flow of effluent
stops. Each linear motion of the stem allows the rubber flap disk to rotate half the distance
necessary to reach the next outlet. When there is no flow, the rubber flap disk is in the “up”
position and is not seated against the valve bottom.

CRITERIA, call Orenco Systems, Inc. at 1-800-348-9843.
The Distributing Valve Assembly
The Orenco Automatic Distributing Valve Assembly combines the distributing valve itself and sever-
al other components to give a complete preassembled unit that is easy to install, monitor, and main-
tain. Figure 2 shows a complete assembly. Because distributing valves with several outlets can be
difficult to line up and glue together in the field, the discharge lines in the assemblies are glued in
place at Orenco. The unions (1) allow removal and maintenance of the valve. The clear PVC pipe
sections (2) give a visual check of which discharge line is being pressurized. The inlet ball valve (3)
allows a quick, simple method to test for proper valve cycling. The ball valve also stops the flow of
effluent in case the pump is activated unexpectedly during maintenance or inspection. Check valves
may be necessary on the discharge lines. Use of check valves is discussed in the valve positioning
section.
Valve Assembly Hydraulics
Liquid flowing through the valve assembly must pass through fairly small openings and make several
changes in direction. Because of this, headlosses through the valve assembly are fairly high. Table 1
gives the headloss equations for several different assemblies and Figure 3 shows the graphical repre-
sentations of these equations. Orenco recommends that high-head turbine pumps be used to pressur-
ize the valve assemblies to ensure enough head is available for proper system operation. High-head
turbine pumps are also recommended because the use of a distributing valve usually requires more
frequent pump cycling. The high-head turbine pumps are designed for high cycling systems and will
outlast conventional effluent pumps by a factor of 10 or more in a high cycling mode. Furthermore,
the high-head turbine pump intake is 12 inches or more above the bottom of the pump and tends to
prevent any settled solids from being pumped into the distribution valve and obstructing its opera-
tion. A minimum flow rate through the distributing valve is required to ensure proper seating of the
rubber flap disk. Minimum flow rates for the various models are given in Table 1.

The Pumping System
Although the distributing valve was designed for the irrigation industry, it has started to gain fairly
wide acceptance in the effluent pumping industry. However, because of the mechanical movements
of the valve, it is necessary to take steps to prevent solids from reaching the distributing valve that
may impede the operation of the valve. Orenco Biotube®Pump Vaults — when properly sized and
installed — provide the necessary protection to prevent valve malfunction. The Biotube®pump vault
accepts effluent only from the clear zone between a tank’s scum and sludge layers and then filters
this effluent through a very large surface area screen cartridge. Without this protection in effluent
systems, the valve has very little chance of reliable long-term operation.
Figure 3:
Automatic distributing valve assembly headloss curves
Valve Positioning
The physical position of the valve in relation to the pump and the discharge point is very important
for proper valve operation. The most reliable operation occurs when the valve is placed at the high
point in the system and as close to the pump as possible. The transport line between the pump and
valve should be kept full if possible. If the line is empty at the beginning of each cycle, pockets of
air during filling can cause random rotation of the valve. The valve is particularly vulnerable to this
erratic rotation with empty lines that are long and not laid at a constant grade. An ideal valve loca-
tion is shown in Figure 4.
If the final discharge point is more than about 2 feet above the valve and the system does not drain
back into the dosing tank, check valves should be installed on the lines immediately following the
valve and a pressure release hole or line should be installed just prior to the valve. This pressure
release hole or line can go into a return line to the dosing tank or to a “minidrainfield” near the valve.
In order for the valve to rotate reliably, no more than about 2 feet of head should remain against the
valve to allow the rubber flap disk to return to its up position. In many cases, it may take from one
minute to several minutes for the pressure in the valve to be lowered enough for proper rotation to
occur. Special care should be taken when installing systems controlled by programmable timers to
ensure cycling does not occur too rapidly. Figure 5 illustrates a valve assembly using check valves.
Pumping downhill to the valve should be avoided unless the transport line is very short and the ele-
vation between the discharge line out of the tank and the valve is less than about 2 feet. If the valve
is located many feet below the dosing tank, random cycling may occur while the transport line drains
through the valve at the end of the cycle. A pressure sustaining valve located just before the distrib-
uting valve may overcome this problem in some instances.

System Startup
Refer to the Hydrotek Valve booklet that is provided with the distributing valve assembly for the
sequencing of the valve outlets. The transport line should always be flushed with clean water before
installing the valve. Any sand, gravel, or other foreign objects that may have been in the pipe during
installation can easily become lodged in the distributing valve, causing malfunction.
With the pump running, alternately close and open the ball valve on the distributing valve assembly
to check proper rotation of the valve. (Note: If check valves are used on the lines after the distribut-
ing valve, the pump may need to be turned on and off to allow the pressure to be released from the
valve.) If visual operation of which zone is operating is not possible, watch the clear pipe on each
line for indication of which zone is operating.
Maintenance
Annually check for proper operation by following procedures listed in the Hydrotek Valve booklet
and system startup procedures listed above.
Troubleshooting
1. PROBLEM: Valve does not change or cycle to next zone or outlet
CAUSE: The stem and disk assembly is not rotating when water flow is turned off and then
back on.
SOLUTION 1: Ensure that there is no debris inside the cam. Clean and carefully reinstall the cam.
SOLUTION 2: If fewer than the maximum number of outlets are being used, check the installation
of the cam. Ensure that the stem and disk assembly is not being held down by an
improperly installed cam. Refer to the cam replacement instructions.

SOLUTION 3: Remove the valve top and check for proper movement of stem and disk assembly.
Check for and remove any debris or foreign objects that may jam or retard the
movement of the disk.
SOLUTION 4: Check for freedom of movement of stem and disk assembly up and down over the
center pin in bottom of valve. Scale deposits may build up on the pin and hold stem
and disk assembly down. Clean pin and again check for freedom of movement.
SOLUTION 5: Be sure that all operating outlets are not capped and that the flow to operating zones
is not restricted in any manner. This would cause pressure to build up in the valve
and lock the stem and disk assembly in the down position.
SOLUTION 6: The backflow of water from uphill lines may be preventing the valve from cycling
properly. This can happen when the valve is placed too far below an elevated line.
If the valve cannot be placed close to the high point of the system, a check valve
should be installed near the valve in the outlet line that runs uphill from the valve
and a drain line installed just prior to the valve to relieve the pressure.
2. PROBLEM: Water comes out of all the valve outlets
CAUSE: Stem and disk assembly not seating properly on valve outlet.
SOLUTION 1: Check for sufficient water flow. A minimum flow rate is required to properly seat
the disk as shown in Table 1.
SOLUTION 2: Remove the valve top and check the inside walls to ensure that nothing is interfering
with the up and down movement of the stem and disk assembly inside the valve.
SOLUTION 3: Make sure that the operating outlets are not capped and that the flow to the operat-
ing zones are not restricted in any manner.
3. PROBLEM: Valve skips outlets or zones
CAUSE: Pumping into an empty transport line — especially downhill — may cause the valve
to skip outlets from pockets of air allowing the rubber flap disk to raise during a
cycle.
SOLUTION 1: Keep the transport line full.
SOLUTION 2: If the line must remain empty between cycles, use a larger diameter transport line
laid at a constant grade to prevent air pockets from forming.
CAUSE: The stem and disk assembly is being advanced past the desired outlet.
SOLUTION 1: Ensure that the correct cam for the desired number of zones is installed and that the
outlet lines are installed to the correct outlet ports of the valve as indicated by the
zone numbers on the top of the cam.

Distributing Valves
General
Orenco’s Automatic Distributing Valve Assemblies are
mechanically operated and sequentially redirect the
pump’s flow to multiple zones or cells in a distribution
field. Valve actuation is accomplished by a combination
of pressure and flow. Automatic Distributing Valve
Assemblies allow the use of smaller horsepower pumps
on large sand filters and drainfields. For example, a large
community drainfield requiring 300 gpm can use a six-line
Valve Assembly to reduce the pump flow rate requirement
to only 50 gpm.
Orenco only warrants Automatic Distributing Valves when
used in conjunction with High-Head Effluent Pumps with
Biotube®Pump Vaults to provide pressure and flow
requirements, and to prevent debris from fouling valve
operation. An inlet ball valve and a section of clear pipe
and union for each outlet are provided for a complete
assembly that is easy to maintain and monitor. Ideal
valve location is at the high point in the system. Refer to
Automatic Distributing Valve Assemblies (NTP-VA-1) for
more information.
