RE: Final approval of the: Septic System Installation, OWTS-016571-2019 Property location:
28525 Brush Creek Road, Basalt Area.
Camp Grandma Lukey, LLC:
This letter is to inform you that the above-referenced, OWTS-016571-2019 permit, has been
inspected and finalized. This OWTS permit is design to serve the existing showers and
handwashing sinks for a Summer overnight camp with a maximum capacity of 12 camp sites
(tipis) and 48 total campers and staff.
Additional information about the maintenance your septic system needs can be accessed
through our website links, provided on the 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
tap roots, irrigation systems and parking areas above the soil treatment area can cause
premature system failure. It is equally important that you notice and immediately repair
dripping faucets and hissing toilets as this will certainly cause the system to fail.
If you have any questions regarding this information, please contact us at (970) 328-8755 and
reference the OWTS septic permit number.
Best Regards,
Giovanna Harkay.

Onsite Wastewater Treatment System (OWTS) Installation Observations
28525 Brush Creek Road
Eagle County, Colorado
Permit Number OWTS-016571-2019
Danny,
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on June 11, 2019 for the subject property. You installed the system, with the assistance of Manny Landa
and Skyline Excavation.
The well is located approximately 195-feet from the soil treatment area (STA). The existing STA serving
the 3-bedroom residence is approximately 225+’ from the new STA.
The OWTS design is based on 1000 gallons per day (GPD). There is no correlation with the proposed
use to Table 6-2 of the OWTS Regulation. Flow into the STA must be tracked. This can be done by
reading the pump counter in the Orenco® control panel. The calculated volume of 88 gallons per
pump cycle must be cross-referenced with the number of campers per session. Calculations will
be utilized to determine actual flow to the STA and create a baseline of actual water usage. If flow
exceeds 1000 GPD, this office must be contacted. We have also provided specifications on an additional
meter with a data-logger, as an option.
The system installation included one 1000-gallon, single-compartment Infiltrator® poly septic tank,
followed by a 1000 gallon two-compartment Infiltrator® poly septic tank with an Orenco® Effluent Filter
on the outlet tee, followed by a 500-gallon, single-compartment Infiltrator® poly septic tank with an
Orenco® ProPak and PF5005 pump. Where the 4-inch sewer line crosses the driveway, Schedule 40-pipe
was utilized. Filters must be cleaned annually, or as needed. The floats were set dose approximately 90
gallons each pump cycle, allowing approximately 2 gallons for drain back. The control panel for the pump is
located on the chicken coop, within line of sight of the septic tank. Valley Precast out of Buena Vista
performed start-up of the pumping system.
A 1.5-inch diameter Schedule 40 pump line was installed from the pump to an Orenco® automatic
distributing valve (ADV), model 6402. The ADV was placed at the high point in the system in an insulated
riser with access from grade.
Effluent is pressure dosed through 1.5-inch diameter pump lines to two beds, each 10’ x 62.5’. A minimum
of 3-feet of sand filter material was installed in the over-excavated footprint. A gradation for the sand filter
material is enclosed.
Laterals were 1.5-inches in diameter with 5/32-inch diameter orifices facing down, spaced 3-feet on center,
installed on the GeoMat™ with the filter fabric over the laterals. Each 1.5-inch diameter lateral ends in a
sweeping ell facing up with a ball valve for flushing. Topsoil was imported for cover over the GeoMat™.
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 OW TS 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.

Data Logging
MAG-UM-01412-EN-03 (February 2016)User Manual
FIRMWARE COMPATIBILITY
The Data Logging feature requires firmware version 1.10 or later.
Reference Badger Meter P/N 67354-003 to obtain a firmware
upgrade kit.
DESCRIPTION
The Data Logging kit (P/N 67354-007) includes:
•Data logging token
•Software CD
•RS232 cable
•USB-to-serial cable
The Data Logging feature records three types of events to a
memory token:
•Totalizer/error events
•Configuration change events
•Startup events (power up, power down or reset events)
Each type of event is recorded into three separate files stored on
the memory token. These files are extracted using the provided
Flow Meter Tool software over the RS232 communication link.
Totalizer/Error events have a programmable interval to which
these events are periodically recorded to the memory token. On
each interval the totalizers are recorded in addition to any errors
that have occurred from the last interval.
The table below defines the capacity of the memory token
configured for data logging.
Interval Totalizer / Error Events
15 min 104 days
1 hr 1 yr, 51 days
12 hr 13 yr
24 hr 27 yr
Each configuration event identifies the parameter that was
modified and to what value the parameter was changed. Up to 768
configuration events can be recorded.
Each startup event identifies the time and reason of the event.
Logging the startup events can help detail how long the meter has
been without power. Up to 768 startup events can be recorded.
Over time the Data Logging will reach capacity of the memory
token. Any new events to be recorded will overwrite the oldest
event on record.
CONFIGURING DATA LOGGING
Data Logging configuration is accomplished within the Advanced >
Data Logger menu. This includes configuring the real time system
clock and the Data Logging interval.
In addition, the configurable parameter, NUMBER OF RECORDS
TO EXTRACT, can be set within the flow meter tool software under
Advanced Flow Meter Settings. This parameter indicates the number
of most recent events for each file to be extracted from the meter
and is limited to 10,000 events.
Prior to enabling data logging, it is important to set up the system
clock using 24-hour mode (2:28 p.m. is entered as 14:28:00). The
system clock configuration is in the Advanced > Data Logger >
Set System Clock menu. The time is officially set when exiting the
Set System Clock menu. We recommend setting the system clock
minutes one minute ahead of actual time because the seconds are
non-configurable. Wait for the actual seconds to roll over to zero
then select Enter to exit the system clock configuration menu.
After the system clock is configured, it can be viewed at any time
from within the Advanced > Data Logger > View System Clock menu.
Once the system clock is configured, make sure the supplied
memory token is inserted into the meter before configuring the
Data Logging interval time. Configuring the interval time will
format the memory token (when necessary) and assign it to the
meter. This formatting process can take approximately 30 seconds.
A flash screen indicates if the token is being formatted.
OTEE:N Placing this token after it has been formatted into an
alternate meter will reformat the token and all previously
logged data will be lost.
The Data Logging interval time can be configured within
the Advanced > Data Logger > Logging Interval menu.
Data Logging is enabled once the data logging interval is
set to a value other than disabled and the Data Logging
token is installed in the meter.

Subsurface Investigation and Onsite Wastewater Treatment System Design
Ajax Adventure Camp
28525 Brush Creek Road
Eagle County, Colorado
Danny,
ALL SERVICE septic, LLC performed a subsurface investigation and completed an onsite wastewater
treatment system (OWTS) design for the subject residence. The 40-acre property is located outside of
Basalt, in an area where OW TSs and wells are necessary.

Parcel ID: 2473-054-00-004
SITE CONDITIONS
The property is being utilized as a summer educational camp and recreation facility. The camp has been
approved to be developed in two (2) phases, per Eagle County Board of County Commissioners
Resolution No. 2018-066. Allowed development includes sites for up to twelve (12) tipi platforms with no
more than 48 beds, a barn structure with commercial kitchen, pit toilets and/or a future OWTS, and a
ropes course.
A 2-bedroom residence presently exists on the property and is utilizing an existing OWTS. Proposed
total build-out of the camp will likely exceed 1999 gallons/day; therefore, Water Quality Site Application1
will apply. Zones of influence for both the existing soil treatment area (STA) and proposed STA have
been calculated at 100-feet.
The proposed STA has an approximate 5-10% slope to the south and southwest. The area is covered
with native grasses.
There is an existing well on the property. The well is located greater than 50-feet from the proposed
septic tanks and greater than 100-feet from the proposed STA. If an additional well will be drilled,
minimum setback distances to OWTS components must be maintained.

SUBSURFACE
The subsurface was investigated on April 24, 2019 by digging three soil profile test pit excavations (Test
Pits). Visual and tactile soil analysis was completed by Carla Ostberg.2
The materials encountered in the Test Pit #1 consisted of dark brown, moist, clayey topsoil to 2.0-feet,
underlain by greenish gray limestone with a tan to medium brown matrix to a maximum depth explored of
8.0-feet. The soils have a blocky structure shape, a moderate structure grade, and friable consistence.
No evidence of groundwater was encountered during excavation.
The materials encountered in the Test Pit #2 consisted of dark brown, moist, clayey topsoil to 2.0-feet,
underlain by greenish gray limestone with a tan to medium brown matrix to a maximum depth explored of
8.0-feet. No evidence of groundwater was encountered during excavation.
The materials encountered in Test Pit #3 consisted of dark brown, moist, clayey topsoil to 3.0-feet, underlain
by reddish, unknown material (possible bury pit) to 4.0-feet, underlain by greenish gray limestone with a tan
to medium brown matrix to a maximum depth explored of 6.0-feet. No evidence of groundwater was
encountered during excavation.
Limestone is classified as Soil Type R-0. Matrix soils are classified as Soil Type 2, Silty Loam with
moderate structure grade. An over-excavated, unlined sand filter with 3-feet of sand filter material
(Secondary Sand) is proposed. A long term acceptance rate (LTAR) of 0.8 gallons per square foot,
will be used to design the OWTS.

DESIGN SPECIFICATIONS
Design Calculations:
Average Design Flow = 1000 gallons per day (GPD)
Showers to accommodate up to 48 campers (estimated approx. 20 gallons/camper)
Min. Tank Capacity = 2000 gallons
LTAR = 0.8 GPD/SF
1000 GPD / 0.8 GPD/SF = 1250 SF
The OWTS design is based on 1000 GPD. There is no correlation with the proposed use to Table 6-2 of
the OWTS Regulation. A shower fixture is noted as 14.7 gallons per day and lavatories at 8.4 gallons
per day; however, this flow is estimated under residential use. For the purpose of this design, we are
estimating a design flow at 20 gallons/camper for use of showers and lavatories only. Flow into the STA
must be tracked. This can be done by reading the pump counter in the Orenco® control panel. The
calculated volume must be cross-referenced with the number of campers per session.
Calculations will be utilized to determine actual flow to the STA and create a baseline of actual water
usage. If flow exceeds 1000 GPD, this office must be contacted. We will also provide specifications on
an additional meter with a data-logger, as an option.
For the purposes of this OWTS design, Benchmark Elevation has been established as 100’ (sewer line
existing shower room. 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 98’
Pump Tank Invert Min. 97’
Automatic Distributing Valve Min. 98’
Infiltrative Surface Min. 97’
A 4-inch diameter SDR-35 sewer line with a double sweep clean out and minimum 2% fall to the septic
tank will exit the shower room. A clean out should be placed a minimum of every 100-feet.
The system installation will include one 1000-gallon, single-compartment3 Infiltrator® poly septic tank,
followed by a two-compartment Infiltrator® poly septic tank with an Orenco® Effluent Filter on the outlet
tee, followed by a 500-gallon, single-compartment Infiltrator® poly septic tank with an Orenco® ProPak
and PF5005 pump. The floats should be set to dose approximately 90 gallons each pump cycle, allowing
approximately 7 gallons for drain back. 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.
Calculations of actual dose volume must be made prior to system start up for proper volume
tracking. This office will provide calculations for actual dose volume once final piping is installed.
A 1.5-inch diameter Schedule 40 pump line must be installed from the pump 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 through a 1.5-inch diameter pump lines to two beds, each 10’ x 62.5’. A
minimum of 3-feet of sand filter material will be installed in the over-excavated footprint. Sand filter material
3 Only two-compartment poly septic tanks are distributed locally. The baffle can be removed to create a single-
compartment septic tank.
Page 6
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 submitted to this office prior to obtaining the sand.
Laterals must be 1.5-inches in diameter with 5/32-inch diameter orifices facing down, spaced 3-feet on
center, installed on the GeoMat™ with the filter fabric over the laterals. Laterals should be placed 2-feet
from the edges of the bed, with the center lateral 4-feet from the outer laterals. Note that the GeoMat™ is
39-inches wide, so three GeoMat™ must be placed on the 10-foot wide bed. GeoMats™ will over-lap
slightly. All material associated with the GeoMat™ installation must be proprietary products associated with
the GeoMat™, including orifice shields and geotextile fabric. Manufacturer instructions must be followed
regarding installation of the GeoMat™.
Each 1.5-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. Laterals
must be covered by a soil separation fabric and at least 1-foot of topsoil or other suitable soil able to support
vegetative growth. There shall be no cobble-sized (<2.5”) or greater rock in final cover over the GeoMat™
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.
INSTALLATION CONTRACTOR
ALL SERVICE septic, LLC 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
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.
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.
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.
Page 7
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.
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.
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.

Residential Biotube® Effluent Filters
Applications
Our patented* 4-in. (100-mm) Biotube Effluent Filters, Biotube Jr., Biotube
Insert Filters, and Biotube Base Inlet Filters are ideal for residential septic
tanks and have a lifetime warranty. They prevent large solids from leaving
the tank, dramatically improving wastewater quality and extending the life
of residential drainfields.
Standard Features & Benefits
• Alarm available, to
signal the need for
cleaning
• Flow modulating
discharge orifices
available to limit
flow rate leaving
tank, mitigat-
ing surges and
increasing
retention time
• Custom and
commercial sizes
available
Effluent from the
relatively clear zone
of the septic tank,
between the scum
and sludge layers,
horizontally enters
the Biotube Effluent
Filter. Effluent then
enters the annular
space between the
housing and the
Biotubes, utilizing
the Biotubes’ entire
surface for filtering.
Particles larger than
the Biotube’s mesh
are prevented from
leaving the tank.

Orenco’s superior effluent filters resist clogging better than all other brands. Our stan-
dard, full-sized 4-in. (100-mm) Biotube Effluent Filter provides maximum long-term
protection in a complete package, with housing. Our 4-in. (100-mm) Biotube Jr., at
half the size of our standard model, has more filtering capacity than the full-sized filters
sold by other manufacturers. For tanks with existing outlet tees, the Biotube Insert Filter
is ideal. And for low-profile tanks, there’s the Base Inlet Filter.

Biotube® ProPak Pump Package™
Technical Data SheetOrenco®
60-Hz Series Pump Packages General
Orenco’s Biotube® ProPak™ is a complete, integrated pump package for
filtering and pumping effluent from septic tanks. And its patented pump
vault technology eliminates the need for separate dosing tanks.
This document provides detailed information on the ProPak pump vault
and filter, 4-in. (100-mm) 60-Hz turbine effluent pump, and control panel.
For more information on other ProPak components, see the following
Orenco technical documents:
• Float Switch Assemblies (NSU-MF-MF-1)
• Discharge Assemblies (NTD-HV-HV-1)
• Splice Boxes (NTD-SB-SB-1)
• External Splice Box (NTD-SB-SB-1)
Applications
The Biotube ProPak is designed to filter and pump effluent to either
gravity or pressurized discharge points. It is intended for use in a septic
tank (one- or two-compartment) and can also be used in a pump tank.
The Biotube ProPak is designed to allow the effluent filter to be removed
for cleaning without the need to remove the pump vault or pump, simpli-
fying servicing.
Complete packages are available for on-demand or timed dosing sys-
tems with flow rates of 20, 30, and 50-gpm (1.3, 1.9, and 3.2 L/sec),
as well as with 50 Hz and 60 Hz power supplies.

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.

1.0 ABOUT GEOMAT
The GeoMat™ Leaching System (GeoMat), is a low profile leaching system desig ned for maximum
treatment and infiltration of wastewater into soil. GeoMat is nominally 1” thick and available in
widths of 6, 12, and 39 inches. It is comprised of an entangled filament core covered by a
hydroscopic membrane with an incorporated low-pressure distribution pipe.
Due to the shallow burial depth and the high surface area to void space ratio in the GeoMat, gas
exchange has been shown to be significantly greater in GeoMat than in other leach field
technologies. This increased oxygen transfer rate results in increased removal of pathogens,
B.O.D., T.S.S., and nutrients such as nitrogen and phosphorus in a shallower soil profile.
The combination of the highly transmissive core and hygroscopic membrane draw the water
between the application points and uniformly apply the water to the surrounding soil. The soil
then draws the water away from the surrounding membrane through capillary action. This
results in a much more uniform application of water to the soil and minimizes the point loading
associated with other low profile systems.
In general, GeoMat can be utilized in many different configurations; please check with your
regulatory agency or contact Geomatrix for the configurations that may be available in your area.
GeoMat can be installed in trench and bed layouts and function with gravity, pump to gravity,
and pressure distribution (PD) system configurations. GeoMat with 6 inches of ASTM C -33 sand
beneath it can be configured to meet NSF Standard 40. GeoMat can also be used for subsurface
irrigation and nutrient reuse.
Geomatrix products are the result of intensive research and development, including in house and
third-party testing. Test reports are availab le by contacting Geomatrix.

Warning: Only Authorized service providers should install, inspect, maintain, or troubleshoot
the GeoMat Wastewater Treatment System.
5
2.0 GEOMAT TREATMENT CAPABILITIES
When the wastewater is nonresidential in strength, the BOD and TSS should be reduced utilizing
pretreatment or a SoilAir system to ensure that there is sufficient oxygen to reduce BOD;
alternatively the size of the GeoMat system should be increased proportionately to account for
the higher BOD.
Contact Geomatrix for assistance on projects other than single family homes.
3.0 COMPONENT HANDLING AND INSPECTION
Upon delivery inspect to ensure no damage has occurred to the components.
Keep the GeoMat and distribution piping clean and free of soil, dirt, oil, grease , PVC saw dust and
associated debris, and any other substance that m ay impede performance.
Although GeoMat is rugged, it should be handled with care. If components are not used
immediately after delivery or purchase, they should be stored away from sunlight and in a
fashion that will not damage their shape over time. Rolls can be stacked up to 3 high, circle side
down.

5.0 FLOW PATH IN A PROPERLY CONSTRUCTED GEOMAT SYSTEM IS:
5.1. Wastewater flows from a source to a properly sized septic tank or pretreatment unit.
5.2. The water then flows from the septic tank or pretreatment unit after filtration.
5.3. When the GeoMat is installed at a higher elevation than the septic tank or pretreatment
unit, wastewater is directed to a pump chamber for lifting wastewater up to the GeoMat;
unless the pretreatment unit has a pump incorporated.
5.4. Wastewater then flows through the distribution piping for discharge into the GeoMat.
When pressure distribution is utilized, a flow differential of less than 10% between first
and last orifice is recommended.
5.5. Wastewater flows out of the distribution piping through holes/orifices that are in
contact with the core.
5.6. The water then infiltrates through the underlying soil for final polishing and recharge to
the water table.

7.2 GeoMat Piping
In gravity applications, the minimum perforated pipe diameter is 2 inches. In pressure
applications, the minimum pipe diameter is 1 inch.
8.0 SITE LAYOUT
GeoMat must be installed according to applicable state and/or local regulations. If unsure
of the installation requirements for a particular site, contact Geomatrix, your designer,
engineer, and/or regulatory agent.
8.1 System Sizing
See Geomatrix Vermont GeoMat Design Manual for specific guidance in designing
GeoMat Systems.
8.2 Excavation considerations:
GeoMat in a Sand Bed
A minimum of 6 inches of approved sand must be utilized beneath the GeoMat
and 2 inches of sand should be placed over the GeoMat fabric membrane.
GeoMat Flat should be installed utilizing the following parameters:
GeoMat laterals can be butted together, sidewall to sidewall, when laid flat and
in a bed configuration; however, it is best to pull them apart by a minimum of 4
inches edge of core to edge of core.
A minimum of 12 inches of sand should surround the perimeter of the
GeoMat in a bed configuration.
GeoMat Edge should be installed with a minimum spacing of 6 inches center to
center.
GeoMat in Native Soil
GeoMat can be installed directly in native soils.
GeoMat Flat when installed in native soils should be installed utilizing the
following parameters:
GeoMat shall be separated, sidewall to sidewall, from adjacent
rows of GeoMat by the 2 times the width of the GeoMat utilized.
o GeoMat 600 = 12 inches
o GeoMat 1200 = 24 inches
o GeoMat 3900 = 78 inches
When specifically configured for gravity flow, and generally, on all
configurations, the use of SoilAir should be considered. If SoilAir is
not going to be installed, it is advisable to install a conduit from the
outlet baffle of the septic tank to the future SoilAir enclosure
location. The SoilAir enclosure should be located where a power
10
supply can be readily configured. It is also recommended, that an
airline be run from the SoilAir enclosure location and connected to
the wastewater supply pipe serving the GeoMat. This air line
should be a minimum of 2 inch ID SCH40 PVC for a 5 bedroom or
smaller single family home. Please contact Geomatrix for airline
sizing on other projects. The air line should be pitched downwardly
from the SoilAir enclosure location to the wastewater supply pipe
and capped. These components are inexpensive and will facilitate
simple remediation of the system, if necessary in the future.
Contact Geomatrix for SoilAir™ information and design assistance
with SoilAir Systems.
When installed in other than Class I native soils a minimum of 2 inches of
approved sand is required beneath, to the sides, and above the GeoMat.
8.3 Maximum Lengths
In gravity applications, GeoMat piping runs should not exceed 50 feet without a wastewater
feed point.
With pressure distribution, there is no maximum length for GeoMat piping runs; however,
designs should result in a less than 10% flow differential between the first and last orifice.
11
9.0 SITE PREPARATION
The area directly above and adjacent to any septic system should be protected from
heavy vehicle traffic and excess weight loads before,
during and post construction.
Prior to construction, it is recommended that the
proposed septic system location be staked and
flagged/fenced to prevent encroachment during home
construction. If vehicle encroachment is expected to be
a problem, after construction, barriers such as garden
timbers, railroad ties, fences, walls, etc. should be used
to protect the septic system area.
Do not install the system in wet conditions or in
overly moist soil; this can cause smearing and
compaction of the native soil horizons.
The soil between the dispersal trenches shall
remain undisturbed when practical and not in a bed
configuration. If the presence of boulders and/or other
obstacles makes trench construction impractical, the
entire leach field area may be excavated as necessary and backfilled with a minimum 6 inch layer
of approved sand to the design elevation.
9.1. Use the design plan and an engineer scale to measure the location of the system
components on the plan from an existing physical or natural feature. Use a tape measure
and swing ties from the same existing physical or natural features on the plan for location
in the field and transfer the bench mark elevations if too far to work with. If unsure how
to locate these on the plan, please contact Geomatrix, your designer, engineer and/or
regulatory agent. Set stakes for location and elevation reference points. Ensure trees and
shrubs are removed within 10 feet of the GeoMat to prevent root intrusion. No Weeping
Willow or Black Locust trees shall be within 30 feet of the GeoMat. These separation
distances can be minimized through the use of root barriers. Please contact Geomatrix for
assistance.
9.2. Excavate system area to design elevation. Ex cavation depth should allow for approved
sand below the GeoMat if required.
9.3. The bottom of excavation must be level. Excavation should be sufficiently large enough
to accommodate GeoMat system design width and length. Rake the bottom and sides of
the excavation to provide proper scarification and remove stones larger than 1 ½ inches
and any other debris. In fine textured soils prone to compaction, minimize walking in the
excavation to prevent compaction and loss of soil structure.
12
Heavy equipment should be kept off
the sand base. If unavoidable, a
tracked machine with a ground
pressure not exceeding 2.5 psi may be
utilized, with the use of ¾ inch
plywood over the sand as support, to
cross the sand base. You must avoid
multiple trips over the same area,
abrupt starting and stopping and
excessive time spent working in one
location on the sand base. All turns
should be made beyond the sand
footprint and only track in a straight
line across the sand bed. Operating a
machine on the bed should only be
done if absolutely necessary. In
summary, uniform sand density is critical to system performance and can be negativel y
impacted by machinery and other static and dynamic loads on the sand base.
10.0 GEOMAT INSTALLATION
10.1. GeoMat Flat (Horizontal) Installation
10.1.1. Roll out GeoMat. Cut the GeoMat to desired length plus 4 inches.
10.1.2. Separate the core from the fabric. Cut out 2 inches of core from GeoMat ends,
leaving the fabric intact to facilitate future stapling of the ends once the piping is installed.
Piping should be free of saw dust and associated debris before joining. It is best to use a
ratcheting PVC pipe cutter. PVC saw dust and associated debris can clog orifices in the
laterals, keep pipe ends temporarily sealed to avoid soil or other materials from entering
the pipe during installation.
10.1.3. Install laterals into the GeoMat by
feeding it in from one end. Ensure that the
orifices or perforations are aligned and
oriented as desired. Glue distribution pipe
together using two-part solvent weld glue,
and SDR 35 or SCH40 PVC fittings according
to manufacturer’s specifications.
Piping entering the GeoMat should pitch to
the GeoMat or back to the septic or pump
tank in a free-draining manner to prevent
freezing.
10.1.4. When pressure distribution is utilized, install a distal head port/cleanout at the
13
terminal end of each lateral. Extend this to a convenient location a minimum of 6 inches
from the end of the GeoMat. A length of non -perforated pipe of the same size and
construction as the distribution pipe in the GeoMat and coupler may be required.
Connect a sweep 90⁰ elbow or two 45⁰ elbows to this extension pipe. The sweep elbow can
be terminated with a ball valve, expandable gripper plug or threaded end cap.
Glue piping components together as described above.
The distribution piping should not have any holes / orifices outside of the GeoMa t.
This distribution line extension pipe and associated fittings should pitch back to the GeoMat
to prevent freezing.
10.1.5. Make certain that distribution pipe is
centered in the GeoMat on top of core. Make certain
that the perforation / orifices are equidistant from the
ends of the GeoMat. Using an Arrow P22 stapler (or
equivalent), seal ends by stapling the top fabric to the
bottom fabric, being careful to seal the fabric tightly
around where the pipe enters and exits the GeoMat.
Use sufficient staples to ensure that sand cannot
enter the core. Carefully move mat along ground, if it
is not already in desired location and keep inside of
pipe clean.
10.1.6. Again, ensure that the orifices or perforations
are located, aligned, and oriented as desired.
Connect the GeoMat distribution pipe to the septic
tank or pretreatment unit, pressure manifold,
distribution box, pump chamber, etc., per system
design.
10.1.7. Before backfilling, ensure that distribution
lines are centered on the GeoMat core. Confirm that
all piping and the GeoMat are secure, properly glued
and in the correct position and elevation. Take pictures, record all measurements and
notify the applicable regulatory agency for inspection if necessary.
10.2. GeoMat Edge (Vertical) Installation
10.2.1. Roll out GeoMat. Cut the GeoMat to desired length plus 4 inches.
10.2.2. Separate the core from the fabric and cut out 2 inches of core from each end of the
GeoMat. Leave the fabric intact to facilitate stapling and sealing after installing the piping.
The interior and exterior of the p iping should be free of saw dust and associated debris
before joining. Best results are achieved by utilizing a PVC pipe shear. PVC saw dust and
associated debris can clog orifices in the laterals. Keep pipe ends temporarily sealed to
14
avoid soil or other materials from entering the pipe during installation
10.2.3. Install laterals into the GeoMat by feeding it in from one end. Ensure that the flat
section of the orifice shield is aiming down and contacting the core. Glue distribution pipe
together using two-part solvent weld glue and Sch. 40 PVC fittings, according to
manufacturer’s specifications.
Piping on the proximal or distal ends of the GeoMat should pitch to the GeoMat or back to
the septic or pump tank to facilitate draining and prevent freezing.
10.2.4. Install a distal head port/cleanout at the distal end of
each lateral. Extend the interior distribution pipe a
minimum of 6 inches past the end of the GeoMat. A length
of non-perforated pipe, the same size and specification as
the interior distribution pipe and coupler, may be required.
Connect a sweep 90⁰ elbow or two 45⁰ elbows to this distal
end. The sweep elbow(s) can be terminated with a ball valve,
expandable gripper plug or threaded end cap.
Glue piping components together as described above.
The distribution piping should not have any holes / orif ices
beyond the GeoMat core.
This distribution pipe, with or without the extension pipe,
should pitch back to the GeoMat to prevent freezing.
10.2.5. Fasten pipe into place inside the GeoMat with
Geomatrix stake clips on approximately 24 inch centers.
10.2.6. When sealing the ends of the GeoMat, be careful to
seal/staple the surrounding fabric membrane tightly
around the pipe entering and exiting the GeoMat
15
10.2.7.A GeoMat Edge in a Sand Bed
Layout area where GeoMat will be located.
Place the GeoMat with the interior piping and stake clips (previously installed), into the
rough location where it will be backfilled. Turn the GeoMat assembly on edge, pipe and clip
on top, and slide the GeoMat spacing templates over the GeoMat assemblies to maintain
the required 6 inch spacing between GeoMat. Move the GeoMat, installed in the spacing
templates, into the desired position. Using leveling equipment, push stakes into the sand
base until GeoMat is set at desired elevation. Connect Interior GeoMat piping to the supply
manifold.
10.2.7.B GeoMat Edge in Native Soils
Measure out where the GeoMat and associated piping will
be located. Utilizing mason’s line, paint, laser level, etc.
mark out the location where the GeoMat laterals and
associated piping will be located. Excavate to the desired
elevation with excavating or trenching equipment. Place
sand fill in trench bottom if required. Place GeoMat and
previously installed interior distribution piping and stake
clips into trenches. Push stakes into trench bottom to
desired elevation, as determined by leveling equipment.
Connect interior GeoMat piping to the supply manifold.
10.2.8. Confirm that the orifices and shields are aligned and
oriented with the flat side facing the GeoMat core
Complete piping the system per design.
10.2.9. Before backfilling, ensure that all piping and the
GeoMat are secure, properly glued and in the correct position
and elevation. Take pictures, record all measurements and
notify the applicable regulatory agency for inspection if
necessary.
11.0 OPTIONAL AIR SUPPLY LINE
11.1 It is recommended that a n air supply line and a float switch conduit be installed in case
system remediation is necessary, at some point in time, due to time, hydraulic or organic
overloading. For typical installations on a 5 bedroom or smaller single family home with runs
of 50 feet or less, the air supply line should be a minimum of 2 inch SCH40 PVC. Runs from 50
- 200 feet should be a minimum of 3 inch SCH40 PVC. Contact Geomatrix for runs longer
than 200 feet.
The air supply line should pitch towards the GeoMat and is installed by teeing into the
distribution piping anywhere downstream of the septic tank or pump tank at an elevation
equal to or higher than the bottom elevation of the GeoMat. The air supply line is then
16
extended with appropriate fittings to a location that would be convenient for future
connection to a SoilAir Blower. Glue piping components together as described above.
It is also advisable to install a conduit f rom the outlet baffle of the septic tank or from the
pump chamber to the future SoilAir enclosure location. This conduit will be potentially
utilized for a float connection to control the SoilAir blower at some time in the future..
12.0 BACKFILLING
12.1. Carefully place approved sand or suitable soil on the
GeoMat to hold it in place for backfilling. Gently cover the
GeoMat with a layer of approved sand or suitable fill to the
top of the distribution pipe, being careful not to drop backfill
material from an elevation higher than 18 inches.
Install valve boxes over the distal ports if present.
Final cover material for placement over the sand should
be clean and free of stones larger than 1½ inches and debris.
This cover material should be suitable for growing grass.
Acceptable cover depth over the GeoMat distribution
laterals should be from 6 – 24 inches; 12 inches is typical.
Whatever depth is selected, it is recommended that the
depth of cover should ideally not vary by more than 15%
across the entire system and should extend a minimum of 18
inches beyond the sand bed footprint, if present. Final backfill
should be such that surface water drains away from the
GeoMat system and associated tanks.
Heavy equipment should be kept off the system. If unavoidable,
a tracked machine with a ground pressure not exceeding 2.5 psi
may be utilized, with the use of ¾ inch plywood over the
system as support to cross the system if a minimum of 12
inches of specified material is over the internal GeoMat
distribution piping. You must avoid multiple trips over the
same area, abrupt starting and stopping , and excessive time
spent working in one location. All turns should be made
beyond the sand footprint and only track/run in a straight line
across the system. Operating a machine on the bed should only
be done as absolutely necessary. In summary, material
densities are critical to system performance and can be
negatively impacted by machinery and other static and
dynamic loads on and around the system.
17
Uniform cover depth, material consistency, permeability, and compaction across the entire
GeoMat system results in consistent oxygen transfer to the entire system; this results in
uniform performance.
12.2. Cover material should be graded to direct storm and surface water away from the
system. Seed and mulch disturbed area immediately after installation to stabilize soil.

from moving around during insertion into GeoMat;
not for rough handling. When better adhesion is
necessary, for transportation, etc. use PVC primer
and solvent cement on all surfaces where the pipe
and shield touch and then snap on shield in correct
location.

Hi Ray,
Responses are in blue below. I will follow up with a phone call.
Hi Carla. I took a look at the design and have the following comments, concerns and/or questions. A couple of items were probably addressed during your conference call with Geomatrix. I
met Dave Potts when he was out a couple of years ago hunting and he's familiar with this area. He might want to have an excuse for coming out, but it won't be until the fall. I think the WQCD
Policy 6 calculations are correct.
Help us better understand the facility that this system serves. Does the building include just showers with no other sinks, toilets and presumably not the kitchen? Even though the flow will be
measured by the pump event counter and dose volume, please reference how the design flow was determined to be at 1,000 gpd with a reference to Table 6-2 or another similar camp and
facility size/use. We think the flow is reasonable but mentioning that there isn't a clear fit to Table 6-2 helps the reviewer understand the logic. You might want to have the flows tracked and
reported sooner than later (during peak use) to develop a comfort level with the soil treatment area. It will be imperative to monitor fixtures for tightness after the kids use the facilities.
I need to defer to Danny on the building plans. I have not seen these and understand there are only sinks and showers. The toilets to be utilized are the vault privies that were installed
last year. The kitchen is another phase of the project and given the constraints of WQSA-6, we will have to separate the systems to accommodate that future use.
There is no direct correlation between the proposed use as an overnight, back-country camp to Table 6-2. As with many commercial uses, the table does not apply and capturing actual
flow data will be more valuable than a made-up number in a chart. It is my expectation that Danny will be tracking flow immediately. Given this is a start up camp operation with only
showers, I'm not aware of any other camp having data on this partial use. Most camps I'm familiar with have full kitchens, toilets, and showers in use. Danny, are you familiar with any
similar operation that has only implemented showers? Or even similar operations with full build-out and what their daily water usage looks like?
We calculated the 48 hour retention time and came up with a minimum of 2,000 gallons needed before dosing. We can understand the logic of a smaller tank if there are no toilets or kitchen
in this facility but had a difficult time finding a provision in our regulations that takes this into consideration. Maybe you can point us to this section if we're missing something. If the retention
was greater and the flows were on target or lower, the shower facility might be able to accommodate toilets and sinks in the future.
The intent in the original design scope was to construct a max build-out of the field at this time and add tank capacity as the phases were completed. Since we were restricted by
WQSA-6, we scaled down to 1000 GPD, but I did not consider the showers to meet that entire capacity. The way it is presented in the design DOES capture the entire capacity of the
OWTS with the showers; however, my goal was to justify actual water use with tracking of the pump counter and actual flows, which we anticipate to be lower than the design flow.
There is no provision in the regulation that allows less capacity for the tank. "The definition of grey water system was removed as the Commission found that the OWTS application of
the separation of toilet wastes with the remaining wastewater being treated in a down-sized OWTS is inconsistent with other uses of the term grey water." The state has adopted
Graywater (spelled differently than in the former OWTS regulation) for beneficial use, but I understand this is an opt in program. I did not think that Eagle opted-in. You can correct me if
I'm wrong... All of that said, if we are speculating on the design flow to be max 1000 GPD from the showers alone, I guess we will have to add tank capacity now.
You provided the CDPHE Geomatrix, Geomat approval letter and be sure to call out the geotextile fabric around the perimeter must be their proprietary product. The same may be true of the
orifice shields shown in their cross section in that they may have a proprietary shield. Also, please call out the installation and revegetation details outlined in the CDPHE letter in the design
document, especially removing the >2.5" rock and using soil type 1 or 2 for final cover. The design mentions there may be overlap of the 3900 Geomat fabric which we don't think will be
necessary in a ten foot wide bed. They can abut according to the CDPHE letter but overlapping isn't addressed. You might consider taking a 30% reduction but we understand that you might
not want to due to the unknown flow volumes at this time.
I will add the proprietary language from the CDPHE approval letter. We have received the product directly from the manufacturer and have been in touch with them multiple times and
there is no chance of any substitution of product in this case. This design is not eligible for a 30% reduction because you cannot take a reduction for the distribution product in the case
of any sand filter design.
Your design specifies having an experienced installer and we're not familiar with Danny's experience with installing septic systems. I understand that nobody around here has experience with
installing a Geomat but maybe Danny can respond answering this question? He does, however, have a current license.

The language regarding experienced installers is template language intended mostly for Garfield County designs as they do not require installers be licensed or certified in any way.
Danny is the licensed installer in this case, as the owner, for the purpose of assuring he is able to over-see and take charge of the project. He will be participating in the installation and
has hired Manny Landa, former owner of Professional Excavating. I'm not sure what his current company name is, but I've worked with Manny for many years. We have already had
one conference call and will be regrouping after the permit is issued. I have confidence in the experience of those working on this project.
You mention to have a gradation performed. Please specify this needs to be done prior to obtaining the sand.
Sand will be obtained from WSA. See attached. We have all had the conversation about the frequency at which the sand pits test their sand piles. It's only when a new batch is made.
I will check in with them, but to my knowledge this one is current. The reality is the regulation is unreasonable and we cannot force the pits to test their product more frequently. We
know the sand that is available here does not meet the "Preferred" specification and therefore I have sized this sand filter (and all others) on "Secondary" sand. I have a call into Sean
Mello at WSA in case they have a more recent gradation.
Please call or email back with questions. We'll continue to do our best to turn a permit around quickly.
Thanks and have a great weekend.
