Project No. 20-7-129
Subject: Subsoil Study for Foundation Design, Proposed Residence, Lot 5, Spring Park
Ranches, Spring Park Ranch Road, Missouri Heights, Eagle County, Colorado
Dear Greg & Terry:
As requested, Kumar & Associates, Inc. performed a subsoil study for design of foundations at
the subject site. The study was conducted in accordance with our agreement for geotechnical
engineering services to you dated February 4, 2020. The data obtained and our
recommendations based on the proposed construction and subsurface conditions encountered are
presented in this report.
Proposed Construction: The proposed residence will be a one and two story structure over a
crawlspace with an attached garage, located on the site as shown on Figure 1. Ground floor will
be structural over crawlspace and slab -on -grade in the garage. Cut depths are expected to range
between about 3 to 5 feet. Foundation loadings for this type of construction are assumed to be
relatively light and typical of the proposed type of construction.
If building conditions or foundation loadings are significantly different from those described
above, we should be notified to re-evaluate the recommendations presented in this report.
Site Conditions: The building area was vacant and vegetated with oak and sage brush. There is
an existing two-story barn/residence to the southwest. The building area slopes moderately
down to the southeast. There was about 18 inches of snow on the site at the time of our field
exploration.
Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating
three exploratory pits at the approximate locations shown on Figure 1. The logs of the pits are
presented on Figure 2. The subsoils encountered, below about 1 to 2 feet of topsoil, consist of
mostly dense, clayey sand and gravel with cobbles and small boulders. There was two feet of

cobbles and boulders. Results of a gradation analyses performed on samples of the
gravels (minus 5 inch fraction) obtained from the site are presented on Fig. 3. No free
water was observed in the pits at the time of excavation and the soils were slightly moist
to moist.
Foundation Recommendations: Considering the subsoil conditions encountered in the
exploratory pits and the nature of the proposed construction, we recommend spread
footings placed on the undisturbed natural gravels designed for an allowable soil bearing
-pressure of 3,000 psf for support of the proposed residence. Footings should be a
minimum width of 16 inches for continuous walls and 2 feet for columns. Loose and
disturbed soils encountered at the foundation bearing level within the excavation should
be removed and the footing bearing level extended down to the undisturbed natural
gravels. Exterior footings should be provided with adequate cover above their bearing
elevations for frost protection. Placement of footings at least 42 inches below the
exterior grade is typically used in this area. Continuous foundation walls should be
reinforced top and bottom to span local anomalies such as by assuming an unsupported
length of at least 10 feet. Foundation walls acting as retaining structures should be
designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at
least 45 pcf for the on -site gravels, exclusive of oversized rock, as backfill.
Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support
lightly loaded slab -on -grade construction. To reduce the effects of some differential
movement, floor slabs should be separated from all bearing walls and columns with
expansion joints which allow unrestrained vertical movement. Floor slab control joints
should be used to reduce damage due to shrinkage cracking. The requirements for joint
spacing and slab reinforcement should be established by the designer based on
experience and the intended slab use. A minimum 4 inch layer of free -draining gravel
should be placed beneath slabs -on -grade to facilitate drainage and act as a leveling
course. This material should consist of minus 2 inch aggregate with less than 50%
passing the No. 4 sieve and less than 2% passing the No. 200 sieve.
All fill materials for support of floor slabs should be compacted to at least 95 % of
maximum standard Proctor density at a moisture content near optimum. Required fill
can consist of the on -site soils devoid of vegetation, topsoil and oversized rock.
Surface Drainage: The following drainage precautions should be observed during
construction and maintained at all times after the residence has been completed:
1) Inundation of the foundation excavations and underslab areas should be
avoided during construction.
2) Exterior backfill should be adjusted to near optimum moisture and
compacted to at least 95 % of the maximum standard Proctor density in

Subject: Subsoil Study for Foundation Design and Percolation Test, Proposed
Garage/Barn, Lot 5, Spring Park Ranches, Eagle County, Colorado
Dear Mr. Janckila:
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study and
percolation test for foundation and septic disposal designs at the subject site. The study
was conducted in accordance with our agreement for geotechnical engineering services
to Jensen Homes dated March 25, 1999. The data obtained and our recommendations
based on the proposed construction and subsurface conditions encountered are presented
in this report.
Proposed Construction: The proposed garage/barn will be a two story wood frame
structure located on the site as shown on Fig. 1. Ground floor is proposed to be a dirt
barn on the lower level. A portion will have slab -on -grade for office. Cut depths are
expected to range between about 3 to 5 feet. Foundation loadings for this type of
construction are assumed to be relatively light and typical of the proposed type of
construction. The septic disposal system is proposed to be located about 175 feet to the
southwest of the proposed residence.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to re-evaluate the recommendations presented in
this report.
Site Conditions: The site was vacant at the time of our field work. The ground
surface in the building area is relatively flat with a moderate slope down to the
southwest at grades up to about 10%. There is about 4 to 6 feet elevation difference
across the building area. The Monarch Ditch is located about 60 feet downhill to the
southeast of the proposed building. The lot is vegetated with scruboak, sagebrush,
grass and weeds.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating one exploratory pit in the building area and one profile pit in the septic
disposal area at the approximate locations shown on Fig. 1. The logs of the pits are
presented on Fig. 2. The subsoils encountered, below about 2'/2 feet of topsoil and 1 to
11/2 feet of clay and gravel consist of relatively dense slightly silty sandy gravel with

minimum width of 16 inches for continuous walls and 2 feet for columns. Loose and
disturbed soils encountered at the foundation bearing level within the excavation should
be removed and the footing bearing level extended down to the undisturbed natural
gravels. Exterior footings should be provided with adequate cover above their bearing
elevations for frost protection. Placement of footings at least 42 inches below the

maximum standard Proctor density at a moisture content near optimum. Required fill
can consist of the on -site soils devoid of vegetation, topsoil and oversized rock.

construction and maintained at all times after the residence has been completed:
1) Inundation of the foundation excavations and underslab areas should be
avoided during construction.
2) Exterior backfill should be adjusted to near optimum moisture and
compacted to at least 95 % of the maximum standard Proctor density in

pavement and slab areas and to at least 90 % of the maximum standard
Proctor density in landscape areas. Free -draining wall backfill should be
capped with about 2 feet of the on -site, finer graded soils to reduce
surface water infiltration.
3) The ground surface surrounding the exterior of the building should be
sloped to drain away from the foundation in all directions. We
recommend a minimum slope of 12 inches in the first 10 feet in unpaved
areas and a minimum slope of 3 inches in the first 10 feet in pavement
and walkway areas.
4) Roof downspouts and drains should discharge well beyond the limits of
all backfill.
Percolation Testing: Percolation tests were conducted on March 26, 1999 to evaluate
the feasibility of an infiltration septic disposal system at the site. One profile pit and
three percolation holes were dug at the locations shown on Fig. 1. The test ?toles
(nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow
backhoe pits and were soaked with water one day prior to testing. The soils exposed in
the percolation holes are similar to those exposed in the Profile Pit shown on Fig. 2 and
consist of about 21/2 feet of topsoil and 11/2 feet of clay and gravel overlying dense
sandy gravel with cobbles and boulders. The percolation test results are presented in
Table I. The percolation test results indicated an infiltration rate between 60 and 180
minutes per inch with an average of 110 minutes per inch. The tests were conducted in
the clay and gravel soils. Due to the relatively slow percolation rate, the percolation
holes were deepened and additional percolation tests were conducted in the underlying
sandy gravels on April 6, 1999. The additional tests did not percolate. Eagle County
may require that a civil engineer design the infiltration septic disposal system.
Limitations: This study has been conducted in accordance with generally accepted
geotechnical 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 data obtained from the exploratory pits excavated at the
locations indicated on Fig. 1, the proposed type of construction and our experience in
the area. Our findings include interpolation and extrapolation of the subsurface
conditions identified at the exploratory pits 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.
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. We recommend on -site observation of excavations and foundation
bearing strata and testing of structural fill by a representative of the geotechnical
engineer.
If you have any questions or if we may be of further assistance, please let us know.

construction are assumed to be relatively light and typical of the proposed type of
construction. The septic disposal system is proposed to be located about 175 feet to the
southwest of the proposed residence.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to re-evaluate the recommendations presented in
this report.
Site Conditions: The site was vacant at the time of our field work. The ground
surface in the building area is relatively flat with a moderate slope down to the
southwest at grades up to about 10%. There is about 4 to 6 feet elevation difference
across the building area. The Monarch Ditch is located about 60 feet downhill to the
southeast of the proposed building. The lot is vegetated with scruboak, sagebrush,
grass and weeds.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating one exploratory pit in the building area and one profile pit in the septic
disposal area at the approximate locations shown on Fig. 1. The logs of the pits are
presented on Fig. 2. The subsoils encountered, below about 21/2 feet of topsoil and 1 to
1'/2 feet of clay and gravel consist of relatively dense slightly silty sandy gravel with

Effluent will be pumped through a 1.5-inch diameter pump line from the pump chamber 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 exiting the ADV remain visible for future inspection and
maintenance.
Effluent will be pressure dosed to a 12' x 58' partially mounded unlined sand filter. The excavation for the
sand filter will begin 2.0-foot below native grade. A minimum of 3-feet of sand filter material will be installed
in the over -excavated footprint, resulting in 1-foot of sand filter material extending above native grade. 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.
Two laterals will be connected with a level manifold, creating two zones served by the Model 6402 ADV.
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'/z-inch screen and must be retained on a 3/-inch screen. The
manifold must be 1.5-inches in diameter. Laterals must be 1.5-inches in diameter with 5/32-inch diameter
orifices facing down, spaced 3-feet on center (OC). We recommend Orenco® Orifice Shields be installed on
the laterals at each orifice. Laterals will begin 2-feet from the edges of the filter, with 2-feet between each
zone. 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 mound must have a minimum 3:1 slope (horizontal:vertical); therefore, the basal area will extend
approximately 9-feet beyond the sand filter on all sides (with a mound height of 3-feet above native grade).
Soils in the sloped perimeter areas of the mound must be well draining and able to support vegetative
growth. The mound must be crowned in a manner to promote drainage off the STA.

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.
INSTALLATION CONTRACTOR
CBO Inc. expects that the installer be experienced and qualified to perform the scope of work outlined in this
design. The installer must review this design thoroughly and coordinate with our office in advance of
installation. Any additional conditions in this design or county permit must be completed and documented
prior to final approval of the OWTS installation. Communication between the installer and this office is
expected throughout the installation.
INSTALLATION OBSERVATIONS
CBO Inc. 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. CBO Inc. should be notified 48 hours
in advance to observe the installation.
In an effort to improve the accuracy of the record drawing, we request that the installer provide a
sketch of the installation, including path of the sewer lines, water line installation (if applicable),
septic tank location, STA location, and measurements from building corners or another fixed
objects on the property. This sketch is most easily provided on Sheet W2.0 of the OWTS Design
Packet. Photographs of the installation and final cover are also requested to supplement our installation
documentation.
Page 9
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 irrigation 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. Machines with tracks (not wheels) should be used during
construction of the STA for better weight distribution. 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.
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.
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.
LIMITS:
The design is based on information submitted. If soil conditions encountered are different from conditions
described in report, CBO Inc. 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.
Sincerely,
CBO Inc.

Defensible Space Requirements: A pre -construction meeting may be required, contact EC Wildfire
Mitigation upon issuance of building permit (970-328-8742)
Zone 1: Is the area of maximum modification and treatment. The intent of Zone 1 is to reduce fuels that are
immediately adjacent to flammable elements of the structure, and to provide a clear access for firefighting
operations. Zone 1 is an area measured 30 feet from the edges of the structure. Ideally, all trees within Zone 1
should be removed to reduce the fire hazard. If a tree or cluster of trees must remain, it will be considered as an
integral part of the structure and Defensible Space will be measured from the drip line of the tree or tree cluster.
Decorative rock or irrigated, mowed grass creates an attractive, easily maintained nonflammable ground cover. All
branches that interfere with the structure's roof or chimney must be removed. All ladder fuels (small shrubs, trees,
tree limbs and other materials that allow fire to climb into the tree crown) must be removed from beneath the tree or
tree cluster.
Zone 2: Within this zone, the continuity and arrangement of vegetation is modified to reduce the intensity of any fire
approaching the structure. Zone 2 is an area measured 30-100 feet from the edges of the structure (or to
property boundaries on smaller lots). Trees and shrubs must be thinned so that there is a minimum of 10 feet
between crowns. Crown separation is measured from the furthest branch of one tree to the nearest branch on the
next tree. All ladder fuels from under these trees must be removed. All trees must be pruned to at least: 10 feet
above the ground, but no more than 1/3 the overall height of the tree (Aspen trees, individual spruce, fir and pine
specimens are exempt). The inner portions of Zone 2 must be more heavily thinned than the outer portions. Isolated
shrubs may remain provided they are not under tree crowns. These shrubs must be pruned and maintained for
vigorous growth. Dead stems and shrubs must be removed. Dead trees, which can fall onto a structure or block an
access, must be removed.

Building Inspection Process - New Building Construction / Exterior Modification / Additions — for all
properties in unincorporated Eagle County
4 Initial Site Inspection (Wildfire 1) — In areas of moderate, high, and extreme wildfire hazard you will
need to have defensible space established around the new or existing structure. An initial site inspection by
the Eagle County wildfire mitigation specialist will determine the parameters for the creation of defensible
space on your property. This must be completed prior to footing or foundation inspections. You will need the
following prior to this site -visit:
• Approved field set of site plans available.
• Building corners marked with stakes outlining the approximate footprint of any new structures,
drive -way, septic, etc.
-i Second Site Inspection (Wildfire 2) — A second visit to your construction site by the wildfire mitigation
specialist may be required during the building process. This visit is to confirm that defensible space around
the structure is in place prior to adding combustible material to the site. All vegetation marked for removal
during the initial site visit must be gone in order to move on to the next step in the mitigation process.
4 Final wildfire inspection (Wildfire Final) — Prior to issuance of Temporary Certificate of Occupancy
(TCO) or Certificate of Occupancy (CO), you must be approved by the wildfire mitigation specialist during
your final wildfire inspection. The following will be examined to ensure:
• That any new landscaping complies with requirements for defensible space (must have approved
landscaping plans on site if not complete)
• That information about the building, location of water for fire suppression, access, and defensible
space boundaries are captured
• That no new factors contribute to the overall wildfire hazards on the site

1 GFP = glass -filled polypropylene; SS = stainless steel. The 1 N-in. NPT GFP discharge
is 2 718 in. octagonal across flats; the 1 N-in. NPT SS discharge is 2 118 in. octagonal across flats; and the
2-in. NPT SS discharge is 2 718 in. hexagonal across flats.
Discharge is female NPT threaded, U.S. nominal size, to accommodate OrencoO discharge hose and valve assemblies. Consult your Orenco
Distributor about fittings to connect hose and valve assemblies to metric -sized piping.
2 Minimum liquid level is for single pumps when installed
in an
Orenco BiotubO Pump Vault or Universal Flow Inducer.
In other applications, minimum liquid level should be top of pump. Consult
Orenco for more information.
3 Weight includes carton and 1 D-ft (3-m) cord.
4 High-pressure discharge assembly required.
5 Do not use cam -lock option (0) on discharge assembly.
6 Custom discharge assembly required for these pumps. Contact Orenco.
7 Capacitor pack (sold separately or installed in a custom
control panel) required for this
pump. Contact Orenco.
8 Torque locks are available for all pumps, and are supplied with 3-hp and 5-hp
pumps.

Motor Franklin motor exterior constructed of stainless steel. Motor filled with deionized water and propylene glycol for constant lubrication. Hermetically
sealed motor housing ensures moisture -free windings. All thrust absorbed by Kingsbury -type thrust bearing. Rated for continuous duty. Single-
phase motors and 200 and 230 V 3-phase motors equipped with surge arrestors for added security. Single-phase motors through 1.5 hp
(1.11 k" have built-in thermal overload protection, which trips at 203-221 ° F (95-105° C).
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 Usec) 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.

Orenco Automatic Distributing
Valve Assemblies
For Wastewater Effluent Systems
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 O to seat against the valve bottom ©.
The opening © in the rubber flap disk aligns with an opening in the valve bottom to allow
flow to only one valve outlet. The stem O 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 ©. 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.

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.

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.
NTP-VA-1
Rev.1.2, ©11/03
tlrenco Systems', Inc.
Page 5 of 6
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.

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.
