Site Location: Bright's Creek Subdivision is located in Polk County. The subdivision is
accessed from the end of Palmer Road (S.R. 1155). More Specifically, this section of the
project is located off Glen Court just south of the intersection with Deep Gap Farm Road
West.
Project Description: This project involves the extension of a low pressure sewer system
to serve 10 new single family cottages. The proposed system is an extension of the
Bright's Creek Phase 2A low pressure sewer system designed by Land Design, Inc. for
Heater Utilities, Inc. Currently this system is owned and operated by Aqua North
Carolina. The wastewater disposal system is a non -conjunctive reclaimed water
utilization system with a permit number of WQ0024694 called the Brights Creek Golf
Club WWTP. A Certificate of Public Necessity was issued by North Carolina Utilities
Commission approved under Docket No. W-2018, Sub 341.
Sewer Extension Description: This project extension of the Bright's Creek Phase 2A
section is a connection at the intersection of Zone 41 and 42 as shown on the Sewer As -
built drawings provided by Aqua. The proposed sewer extension is modeled as Zone 43.
The proposed sewer is sized for 10 residential lots at 360 gpd each. The proposed sewer
shall collect the wastewater and transport it from the pump through the new zone 43 into
the existing low-pressure system at the intersection of zones 41 and 42. The wastewater
will then be transported through zone 41 into zone 35, 36 and 64 into an existing regional
pump station that will convey it to the existing WWTP.

2.01 PUMP: The pump shall be a custom designed, integral, vertical rotor, motor driven, solids handling
pump of the progressing cavity type with a single mechanical seal. Double radial O-ring seals are
required at all casting joints to minimize corrosion and create a protective barrier. All pump castings
DocuSign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
shall be cast iron, fully epoxy coated to 8-10 mil Nominal dry thickness, wet applied. The rotor shall be
through -hardened, highly polished, precipitation hardened stainless steel. The stator shall be of a
specifically compounded ethylene propylene synthetic elastomer. This material shall be suitable for
domestic wastewater service. Its physical properties shall include high tear and abrasion resistance,
grease resistance, water and detergent resistance, temperature stability, excellent aging properties,
and outstanding wear resistance. Buna-N is not acceptable as a stator material because it does not
exhibit the properties as outlined above and required for wastewater service.
2.02 GRINDER: The grinder shall be placed immediately below the pumping elements and shall be direct -
driven by a single, one-piece motor shaft. The grinder impeller (cutter wheel) assembly shall be
securely fastened to the pump motor shaft by means of a threaded connection attaching the grinder
impeller to the motor shaft. Attachment by means of pins or keys will not be acceptable. The grinder
impeller shall be a one-piece, 4140 cutter wheel of the rotating type with inductively hardened cutter
teeth. The cutter teeth shall be inductively hardened to Rockwell 50 — 60c for abrasion resistance. The
shredder ring shall be of the stationary type and the material shall be white cast iron. The teeth shall be
ground into the material to achieve effective grinding. The shredder ring shall have a staggered tooth
pattern with only one edge engaged at a time, maximizing the cutting torque. These materials have
been chosen for their capacity to perform in the intended environment as they are materials with wear
and corrosive resistant properties.
This assembly shall be dynamically balanced and operate without objectionable noise or vibration over
the entire range of recommended operating pressures. The grinder shall be constructed so as to
minimize clogging and jamming under all normal operating conditions including starting. Sufficient
vortex action shall be created to scour the tank free of deposits or sludge banks which would impair the
operation of the pump. These requirements shall be accomplished by the following, in conjunction with
the pump:
1. The grinder shall be positioned in such a way that solids are fed in an upward flow direction.
2. The maximum flow rate through the cutting mechanism must not exceed 4 feet per second. This is
a critical design element to minimize jamming and as such must be adhered to.
3. The inlet shroud shall have a diameter of no less than 5 inches. Inlet shrouds that are less than 5
inches in diameter will not be accepted due to their inability to maintain the specified 4 feet per
second maximum inlet velocity which by design prevents unnecessary jamming of the cutter
mechanism and minimizes blinding of the pump by large objects that block the inlet shroud.
4. The impeller mechanism must rotate at a nominal speed of no greater than 1800 rpm.
The grinder shall be capable of reducing all components in normal domestic sewage, including a
reasonable amount of "foreign objects," such as paper, wood, plastic, glass, wipes, rubber and the like,
to finely -divided particles which will pass freely through the passages of the pump and the 1-1/4"
diameter stainless steel discharge piping.
2.03 ELECTRIC MOTOR: As a maximum, the motor shall be a 1 HP, 1725 RPM, 240 Volt 60 Hertz, 1
Phase, capacitor start, ball bearing, air-cooled induction type with Class F insulation, low starting
current not to exceed 30 amperes and high starting torque of 8.4 foot pounds. The motor shall be
press -fit into the casting for better heat transfer and longer winding life. Inherent protection against
running overloads or locked rotor conditions for the pump motor shall be provided by the use of an
automatic -reset, integral thermal overload protector incorporated into the motor. The motor protector
shall be specifically investigated and listed by Underwriters Laboratories Inc. for the application. Non -
capacitor start motors or permanent split capacitor motors will not be accepted because of their
reduced starting torque and consequent diminished grinding capability. The wet portion of the motor
armature must be 300 Series stainless steel. To reduce the potential of environmental concerns, the
expense of handling and disposing of oil, and the associated maintenance costs, oil -filled motors will
not be accepted. Pump operation during instances of potentially damaging high current or low voltage
conditions shall be inhibited by an in -pump electrical monitoring system that has been investigated and
listed by Underwriters Laboratories Inc. for the application. Motor start shall be controlled by a DC
4
DocuSign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
driven electromechanical relay integrated within the control compartment of the pump. Electrical
monitoring shall ensure the relay operates reliably. AC Mechanical contactors for motor start are
susceptible to damage from short cycling and will not be accepted.
2.04 MECHANICAL SEAL: The pump/core shall be provided with a mechanical shaft seal to prevent
leakage between the motor and pump. The seal shall have a stationary ceramic seat and carbon
rotating surface with faces precision lapped and held in position by a stainless steel spring.

The overall basin capacity shall be 237 gallons. The basin shall incorporate a tapered bottom with an
inside diameter of no greater than 28 inches to minimize the retained volume and shall be designed to
fit into most septic tanks after removal of the septic tank cover. The largest diameter must be no less
than 50 inches and no greater than 52 inches.
A station that is 55 inches tall shall have no greater than a 36 inch outside diameter flat fiberglass
cover. The 55 inch tall station can be extended in 6 inch increments with normal cylindrical fiberglass
extensions.
Taller stations shall have an accessway with a shroud and domed cover. The accessway shall be an
integral extension of the wetwell assembly and shall include a lockable cover assembly with integral
vent providing low profile mounting and watertight capability. The cover shall be high density
polyethylene, green in color, with a load rating of 150 Ibs per square foot. The domed cover shall have
an outside diameter of no greater than 30 inches. Accessway design and construction shall enable field
adjustment of station height in 3" increments without the use of any adhesives or sealants requiring
cure time before installation can be completed. Corrugated sections are to be made of a double -wall
HDPE construction with the internal wall being generally smooth. Corrugations of the outside wall are to
be of a minimum amplitude of 1-1/2 inch to provide necessary transverse stiffness. Any incidental
sections of a single -wall construction are to be a minimum .250 inch thick. All seams created during
tank construction are to be thermally welded and factory tested for leak tightness. The accessway wall

6P electrical quick disconnect (EQD) for all power and control functions. The EQD will be supplied with
32' total, 25' of useable, electrical supply cable (ESC) to connect to the alarm panel. The EQD shall
require no tools for assembly, seal against water before the electrical connection is made, and include
radial seals to assure a watertight seal regardless of tightening torque. Plug -type connections of the
power cable onto the pump housing will not be acceptable due to the potential for leaks and electrical
shorts. Junction boxes are not acceptable due to the large number of potential leak points. The EQD
shall be so designed to be conducive to field wiring as required.
2.08 CHECK VALVE: The pump discharge shall be equipped with a factory installed, gravity operated,
flapper -type integral check valve built into the discharge piping. The check valve will provide a full-
DocuSign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
ported passageway when open, and shall introduce a friction loss of less than 6 inches of water at
maximum rated flow. Moving parts will be made of a 300 Series stainless steel and fabric reinforced
synthetic elastomer to ensure corrosion resistance, dimensional stability, and fatigue strength. A
nonmetallic hinge shall be an integral part of the flapper assembly providing a maximum degree of
freedom to assure seating even at a very low back -pressure. The valve body shall be an injection
molded part made of an engineered thermoplastic resin. The valve shall be rated for continuous
operating pressure of 235 psi. Ball -type check valves are unacceptable due to their limited sealing
capacity in slurry applications.
2.09 ANTI -SIPHON VALVE: The pump discharge shall be equipped with a factory -installed, gravity -
operated, flapper -type integral anti -siphon valve built into the discharge piping. Moving parts will be
made of 300 Series stainless steel and fabric -reinforced synthetic elastomer to ensure corrosion
resistance, dimensional stability, and fatigue strength. A nonmetallic hinge shall be an integral part of
the flapper assembly, providing a maximum degree of freedom to ensure proper operation even at a
very low pressure. The valve body shall be injection -molded from an engineered thermoplastic resin.
Holes or ports in the discharge piping are not acceptable anti -siphon devices due to their tendency to
clog from the solids in the slurry being pumped. The anti -siphon port diameter shall be no less than
60% of the inside diameter of the pump discharge piping.
2.10 CORE UNIT: The grinder pump station shall have an easily removable core assembly containing pump,
motor, grinder, all motor controls, check valve, anti -siphon valve, electrical quick disconnect and wiring.
The watertight integrity of the core unit shall be established by a 100% factory test at a minimum of 5
PSIG.
2.11 CONTROLS: All necessary motor starting controls shall be located in the cast iron enclosure of the
core unit secured by stainless steel fasteners. Locating motor starting controls in a plastic enclosure is
not acceptable. Wastewater level sensing controls shall be housed in a separate enclosure from motor
starting controls. Level sensor housing must be sealed via a radial type seal; solvents or glues are not
acceptable. Level sensing control housing must be integrally attached to pump assembly so that it may
be removed from the station with the pump and in such a way as to minimize the potential for the
accumulation of grease and debris accumulation, etc. Level sensing housing must be a high -impact
thermoplastic copolymer over -molded with a thermo plastic elastomer. The use of PVC for the level
sensing housing is not acceptable.
Non -fouling wastewater level controls for controlling pump operation shall be accomplished by
monitoring the pressure changes in an integral air column connected to a pressure switch. The air
column shall be integrally molded from a thermoplastic elastomer suitable for use in wastewater and
with excellent impact resistance. The air column shall have only a single connection between the water
level being monitored and the pressure switch. Any connections are to be sealed radially with
redundant 0-rings. The level detection device shall have no moving parts in direct contact with the
wastewater and shall be integral to the pump core assembly in a single, readily -exchanged unit.
Depressing the push to run button must operate the pump even with the level sensor housing removed
from the pump.
All fasteners throughout the assembly shall be 300 Series stainless steel. High-level sensing will be
accomplished in the manner detailed above by a separate air column sensor and pressure switch of the
same type. Closure of the high-level sensing device will energize an alarm circuit as well as a
redundant pump -on circuit. For increased reliability, pump ON/OFF and high-level alarm functions shall
not be controlled by the same switch. Float switches of any kind, including float trees, will not be
accepted due to the periodic need to maintain (rinsing, cleaning) such devices and their tendency to
malfunction because of incorrect wiring, tangling, grease buildup, and mechanical cord fatigue. To
assure reliable operation of the pressure switches, each core shall be equipped with a factory installed
equalizer diaphragm that compensates for any atmospheric pressure or temperature changes. Tube or
piping runs outside of the station tank or into tank -mounted junction boxes providing pressure switch
equalization will not be permitted due to their susceptibility to condensation, kinking, pinching, and
insect infestation. The grinder pump will be furnished with a 6 conductor 14 gauge, type SJOW cable,
pre -wired and watertight to meet UL requirements with a FACTORY INSTALLED NEMA 6P EQD half
attached to it.

resetting fuse.
The alarm panel shall include the following features: external audible and visual alarm; push -to -run
switch; push -to -silence switch; redundant pump start; and high level alarm capability. The alarm
sequence is to be as follows when the pump and alarm breakers are on:
1. When liquid level in the sewage wet -well rises above the alarm level, the contacts on the alarm
pressure switch activate, audible and visual alarms are activated, and the redundant pump starting
system is energized.
2. The audible alarm may be silenced by means of the externally mounted, push -to -silence button.
3. Visual alarm remains illuminated until the sewage level in the wet -well drops below the "off' setting
of the alarm pressure switch.
The visual alarm lamp shall be inside a red, oblong lens at least 3.75" L x 2.38" W x 1.5" H. Visual
alarm shall be mounted to the top of the enclosure in such a manner as to maintain NEMA 4X rating.
The audible alarm shall be externally mounted on the bottom of the enclosure, capable of 93 dB @ 2
feet. The audible alarm shall be capable of being deactivated by depressing a push -type switch that is
encapsulated in a weatherproof silicone boot and mounted on the bottom of the enclosure (push -to -
silence button).

Docu$ign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
present at the receptacle, allowing the audible and visual alarms to function normally in generator
mode. When power is no longer applied to the generator receptacle, the panel is automatically switched
back to the AC Mains power. (No manual switching within the panel enclosure is necessary to switch
from generator power back to AC Mains, so the mode cannot be inadvertently left in the generator
position after pumping down the station in generator mode as is the case with a manual transfer
switch).
(OPTIONAL) Service Equipment/Main Service Disconnect Breaker —A separate, internal breaker
rated and approved for use as "service equipment' and acts as a main service disconnect of the grinder
pump station shall be provided.

the pump core shall be provided.
(OPTIONAL) SENTRY SIMPLEX PROTECT:
Provides protection from the following operating conditions:
Low Voltage (Brownout) Protection — A lockout cycle will prevent the motor from operating
and will illuminate an LED if:
o the incoming AC Mains voltage drops below a predetermined minimum, typically 12% of
nameplate (211 volts for a 240 volt system) for 2 to 3 seconds, regardless of whether the
motor is running or not
o the lockout cycle will end if the incoming AC Mains voltage returns to a predetermined
value, typically 10% of nameplate (216 volts for a 240 volt system)
The system continues to retest the voltage every second indefinitely. If the lockout cycle has
been initiated and the voltage comes back above the predetermined starting voltage, the
system will function normally. The LED remains illuminated during a Brownout condition and
remains latched until the pump breaker is turned off and then on again (reset). The audible and
visual alarm will not be activated unless there is a high wastewater level in the tank.
Run Dry Protection — A 20-minute lockout cycle will prevent the motor from operating and will
illuminate an LED when the wastewater level in the tank is below the pump inlet level. The
condition is rechecked every 20 minutes. If the lockout cycle has been initiated and the
condition is satisfied, the pump is not allowed to cycle normally but the LED remains latched.
The LED will remain latched until the pump breaker is turned off and then on again (reset). If
the condition is not satisfied after 3 consecutive attempts, the visual alarm will be activated until
the pump breaker is turned off and on (reset) or until there is one cycle of normal operation. If a
high level condition is presented at any time, a pump run cycle will be activated.
High System Pressure Protection — A 20-minute lockout cycle will prevent the motor from
operating and will illuminate an LED when the pressure in the discharge line is atypically high
(closed valve or abnormal line plug). The condition is rechecked every 20 minutes. If the
condition is satisfied, the pump is allowed to cycle normally but the LED remains latched. If the
condition is not satisfied after 3 consecutive attempts, the pump is locked out indefinitely until
the condition is removed and power is reset. The LED will remain latched until the pump
breaker is turned off and then on again (reset). The audible and visual alarm will be activated.
In all of the above cases, if more than one error condition is presented, the LED depicting the most
recent error condition will be displayed.

done as a part of the work under this section, including any necessary sheeting and bracing.
The CONTRACTOR shall be responsible for handling ground water to provide a firm, dry subgrade for
the structure, and shall guard against flotation or other damage resulting from general water or flooding
The grinder pump stations shall not be set into the excavation until the installation procedures and
excavation have been approved by the ENGINEER.
Remove packing material. User instructions MUST be given to the OWNER. Hardware supplied with
the unit, if required, will be used at installation. The basin will be supplied with a standard 4" inlet
grommet (4.50" OD) for connecting the incoming sewer line. Appropriate inlet piping must be used. The
basin may not be dropped, rolled or laid on its side for any reason.
Installation shall be accomplished so that 1 inch to 4 inches of accessway, below the bottom of the lid,
extends above the finished grade line. The finished grade shall slope away from the unit. The diameter
of the excavated hole must be large enough to allow for the concrete anchor.
A 6" inch (minimum) layer of naturally rounded aggregate, clean and free flowing, with particle size of
not less than 1/8" or more than 3/4" shall be used as bedding material under each unit.
A concrete anti -flotation collar, as detailed on the drawings, and sized according to the manufacturer's
instructions, shall be required and shall be pre -cast to the grinder pump or poured in place. Each
grinder pump station with its pre -cast anti -flotation collar shall have a minimum of three lifting eyes for
loading and unloading purposes.
If the concrete is poured in place, the unit shall be leveled, and filled with water, to the bottom of the
inlet, to help prevent the unit from shifting while the concrete is being poured. The concrete must be
manually vibrated to ensure there are no voids. If it is necessary to pour the concrete to a level higher
than the inlet piping, an 8" sleeve is required over the inlet prior to the concrete being poured.
The CONTRACTOR will provide and install a 4-foot piece of 4-inch SCH 40 PVC pipe with water tight
cap, to stub -out the inlet for the property owners' installation contractor, as depicted on the contract
drawings.

E/One requires that an E/One Uni-Lateral assembly (E/One part number NB0184PXX or NCO193GXX)
or E/One Redundant Check Valve (E/One part number PC0051GXX) be installed in the pipe lateral
outside the home between the pump discharge and the street main on all installations.
The electrical enclosure shall be furnished, installed and wired to the grinder pump station by the
CONTRACTOR. An alarm device is required on every installation, there shall be NO EXCEPTIONS. It
will be the responsibility of the CONTRACTOR and the ENGINEER to coordinate with the individual
property owner(s) to determine the optimum location for the alarm panel.
The CONTRACTOR shall mount the alarm device in a conspicuous location, as per national and local
codes. The alarm panel will be connected to the grinder pump station by a length of 6-conductor type
TC cable as shown on the contract drawings. The power and alarm circuits must be on separate power
circuits. The grinder pump stations will be provided with 32 feet total, 25 feet of useable, electrical
supply cable to connect the station to the alarm panel. This cable shall be supplied with a FACTORY
INSTALLED EQD half to connect to the mating EQD half on the core.
3.05 BACKFILL REQUIREMENTS: Proper backfill is essential to the long-term reliability of any
underground structure. Several methods of backfill are available to produce favorable results with
different native soil conditions. The most highly recommended method of backfilling is to surround the
unit to grade using Class I or Class II backfill material as defined in ASTM 2321. Class 1A and Class 1 B
are recommended where frost heave is a concern; Class 1 B is a better choice when the native soil is
sand or if a high, fluctuating water table is expected. Class 1, angular crushed stone, offers an added
benefit in that it doesn't need to be compacted.
Class II, naturally rounded stone, may require more compactive effort, or tamping, to achieve the proper
density. If the native soil condition consists of clean compactable soil, with less than 12% fines, free of
ice, rocks, roots and organic material, it may be an acceptable backfill. Soil must be compacted in lifts
not to exceed one foot to reach a final Proctor Density of between 85% and 90%. Heavy, non-
compactable clays and silts are not suitable backfill for this or any underground structure such as inlet
or discharge lines.
If you are unsure of the consistency of the native soil, it is recommended that a geotechnical evaluation
of the material is obtained before specifying backfill.
Another option is the use of a flowable fill (i.e., low slump concrete). This is particularly attractive when
installing grinder pump stations in augured holes where tight clearances make it difficult to assure
proper backfilling and compaction with dry materials. Flowable fills should not be dropped more than
four feet from the discharge to the bottom of the hole to avoid separation of the constituent materials.
Backfill of clean, native earth, free of rocks, roots, and foreign objects, shall be thoroughly compacted in
lifts not exceeding 12" to a final Proctor Density of not less than 85%. Improper backfilling may result in
damaged accessways. The grinder pump station shall be installed at a minimum depth from grade to
the top of the 1 1/4" discharge line, to assure maximum frost protection. The finish grade line shall be 1"
to 4" below the bottom of the lid, and final grade shall slope away from the grinder pump station.
All restoration will be the responsibility of the CONTRACTOR. Per unit costs for this item shall be
included in the CONTRACTOR'S bid price for the individual grinder pump station. The properties shall
be restored to their original condition in all respects, including, but not limited to, curb and sidewalk
replacement, landscaping, loaming and seeding, and restoration of the traveled ways, as directed by
the ENGINEER.
3.06 START-UP AND FIELD TESTING: The MANUFACTURER shall provide the services of qualified
factory trained technician(s) who shall inspect the placement and wiring of each station, perform field
tests as specified herein, and instruct the OWNER'S personnel in the operation and maintenance of the
equipment before the stations are accepted by the OWNER.
All equipment and materials necessary to perform testing shall be the responsibility of the INSTALLING
CONTRACTOR. This includes, as a minimum, a portable generator and power cable (if temporary
13
DocuSign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
power is required), water in each basin (filled to a depth sufficient to verify the high level alarm is
operating), and opening of all valves in the system. These steps shall be completed prior to the
qualified factory trained technician(s) arrival on site.
The services of a trained, factory -authorized technician shall be provided at a rate of 40 hours for every
100 grinder pump stations supplied.
Upon completion of the installation, the authorized factory technician(s) will perform the following test
on each station:
1. Make certain the discharge shut-off valve in the station is fully open.
2. Turn ON the alarm power circuit and verify the alarm is functioning properly.
3. Turn ON the pump power circuit. Initiate the pump operation to verify automatic "on/off' controls are
operative. The pump should immediately turn ON.
4. Consult the Manufacturer's Service Manual for detailed start-up procedures.
Upon completion of the start-up and testing, the MANUFACTURER shall submit to the ENGINEER the
start-up authorization form describing the results of the tests performed for each grinder pump station.
Final acceptance of the system will not occur until authorization forms have been received for each
pump station installed and any installation deficiencies corrected.

FAILURE TO COMPLY
WITH INSTALLATION
INSTRUCTIONS WILL
VOID WARRANTY
DocuSign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
The following instructions
define the recommended
procedure for installing the
Model WH/WR231 grinder
pump station.
This is a sewage handling
pump and must be vented in
accordance with local plumbing
codes. This pump is not to be
installed in locations classified
as hazardous in accordance
with National Electric Code,
ANSI / NFPA 70. All piping and
electrical systems must be in
compliance with applicable
local and state codes.
1. REMOVE PACKING
MATERIAL: The User
Instructions must be given to
the homeowner. Hardware
supplied with the unit, if any,
will be used at installation.
2. TANK INSTALLATION:
The tank is typically supplied
with a standard grommet for
connecting the 4" DWV (4.50"
outside dia.) incoming sewer
drain. Other inlet types and
sizes are optional. CAUTION:
4" DR-35 pipe has a smaller
diameter and won't create
a watertight joint with the
standard grommet. Confirm
that you have the correct
inlet before continuing. If a
concrete ballast is attached to
the tank, lift only by the lifting
eyes (rebar) embedded in the
concrete. Do not drop, roll, or
lay tank on its side. This will
damage the unit and void the
warranty.
Excavate a hole to a depth so
that the station cover extends
1" to 2" above the finished
grade line. The finished
grade must slope away from
the station cover to prevent
surface water from entering
the station. The diameter of the
hole shall be large enough to
allow for the concrete ballast
anchor. The size, shape and
shoring requirements of the
excavation will be based on
the soil conditions and must
be in accordance with the site
engineer's recommendation
and safety requirements. Care
must be taken during lifting and
placement to prevent impacting
or otherwise damaging the tank
(see Lifting Instructions). Only
a non -marring sling, rated for
the load being lifted, should
be used in contact with the
tank surfaces. Lifting chains or
cables should not be placed
in direct contact with the tank
surfaces.
Place the station on a bed
of gravel, naturally rounded
aggregate, clean and free
Figure 2a
flowing, with particles not less
than 1/8" or more than 3/4" in
size.
A concrete ballast anchor is
required to prevent flotation of
the tank when groundwater is
present. The concrete anchor
is not optional. The MINIMUM
concrete anchor requirements
for the WHIWR231 station are
shown in Chart 1 of the Ballast
Calculation section. Ensure the
tank is properly positioned in
the excavation to support inlet
pipe (Section 3) and discharge
pipe (Section 5) connections
before pouring the concrete
ballast. The unit should be
leveled and filled with water to
approximately the bottom of
the inlet pipe to prevent shifting

while the ballast is being
poured. The concrete should
be vibrated, as necessary,
to eliminate voids. If it is
necessary to pour the concrete
above the inlet level (Section
3), the inlet must be sleeved
with an 8" tube before pouring.
Concrete ballast should be
cast in -place around the tank
in the excavation (Figure 3).
Alternatively, pre -cast ballast
around the base of the tank
may be used. If the concrete
is pre -cast, lifting hooks must
be anchored in the ballast to
support subsequent handling
of the tank (see Lifting
Instructions). The lifting hooks
used must be adequate to
support the combined weight of
Figure 2b
the tank and concrete ballast
and shall be sized and installed
in accordance with the site
engineer's recommendation.
Place the ballasted tank on
the gravel bedding in the
excavated hole using the
lifting hooks. Do not lift by
any of the tank surfaces if
pre -cast ballast is utilized.
3. INLET LOCATIONS:
A 4" (standard) DWV inlet
grommet was provided with
the station for sealing the
inlet pipe at the tank wall. If
the inlet grommet penetration
was not factory installed, the
location of the tank inlet must
be determined to support final
positioning of the tank prior to
ballast installation (see Section

2). The inlet pipe location
corresponds with the actual or
projected point where the 4"
building sewer line intersects
the tank wall. The grade of
the inlet pipe and required
burial depth (per national
and local code requirements)
must be accounted for when
determining the inlet location.
The supply cable path
should be considered when
selecting the inlet location (see
Section 8). A 5" diameter field
penetration of the tank wall is
required to support installation
of the (standard) inlet grommet.
This penetration must not
remove or interfere with any
of the structural ribbing on the
polyethylene tank. The inlet
grommet may be installed in
any of the allowable locations
shown in Figure 6. The inlet
penetration must be centered
in the location selected to
prevent interference with
the tank ribbing. Typical inlet
installation will be on one of
the three, 6.5" wide, raised
panels on the tank body. The
panels have been marked
with a series of locating lines
to support centering of the 5"
(standard) drilled penetration.
The center of the 4" inlet
location must not be located
below the recommended
minimum inlet center line on
the raised panels (Figure
6). Any inlet installed in the
depressed panels between the
horizontal and vertical ribbing
must be centered within the
panel to provide adequate
clearance for the 6" diameter
flange on the standard 4" inlet
grommet (Figure 6). Once the
location of the inlet penetration
is selected, mark the inlet
center location on the tank
and position the tank. Using
DocuSign Envelope ID: A9FEA7B3-D44D-432C-8A93-AA35F6F1529A
a 5" diameter hole saw for
the standard 4" grommet, drill
through the tank wall at the
marked location. Remove any
chips or burrs from the drilled
hole. Install the provided inlet
grommet into the drilled hole.
The grommet is self-sealing
and does not require the use of
additional sealant or adhesive.
4. INLET PIPE
INSTALLATION: Mark the inlet
pipe 3 1/2" from the end to
be inserted. Inlet pipe should
be chamfered and lubricated
with a soap solution. Lubricate
the inlet grommet with soap
solution as well. Insert the pipe
into the grommet up to the 3.5"
mark. Inspect to ensure the
grommet has remained intact
and in place (Figure 6).
5. DISCHARGE: The use
of 1.25" PVC pressure pipe
SCH 40 and polyethylene
pipe SDR 11 or SIDR 7 are
recommended. If polyethylene
is chosen, use compression -
type fittings to provide a
smooth inner passage.
E/One requires that an
E/One Uni-Lateral assembly
(E/One part number
NBO184PXX or NC0193GXX)
or E/One Redundant Check
Valve (E/One part number
PC0051 GXX) be installed in
the pipe lateral outside the
home between the pump
discharge and the street main
on all installations. Never use
a ball -type valve as a check
valve. E/One recommends
the valve be installed as close
to the public right-of-way as
possible. Check local codes for
applicable requirements.
CAUTION: Redundant check
valves on station laterals
and anti-siphon/check valve
assemblies on grinder pump
cores should not be used as
system isolation valves during
line tests.
There is a slide face valve
and a quick disconnect
pre -installed in the tank for
pump connection. There is a
1.25" NPT female discharge
connection on the outside of
the tank to support discharge
pipe connection.
6. BACKFILL
REQUIREMENTS: Proper
backfill is essential to the
long term reliability of any
underground structure.
Several methods of backfill are
available to produce favorable
results with different native soil
conditions.
The recommended method
of backfilling is to surround
the unit to grade using Class
I or Class II backfill material
as defined in ASTM 2321.
Class 1A and Class 1 B are
recommended where frost
heave is a concern; Class
1 B is a better choice when
the native soil is sand or if a
high, fluctuating water table
is expected. Class I, angular
crushed stone, offers an added
benefit in that it needs minimal
Figure 3
compaction. Class II, naturally
rounded stone, may require
more compactive effort, or
tamping, to achieve the proper
density.
If the native soil condition
consists of clean, compactible
soil with less than 12% fines,
free of ice, rocks, roots, and
organic material, it may be
an acceptable backfill. Such
soil must be compacted in
lifts not to exceed one foot to
reach a final Proctor Density
between 85% and 90%. Non -
compactible clays and silts are
not suitable backfill for this
or any underground structure
such as inlet or discharge
lines. If you are unsure of
the consistency of the native
soil, it is recommended that a
geotechnical evaluation of the
material be obtained before
specifying backfill.
Another option is the use of
a flowable fill (i.e., low slump
concrete). This is particularly
attractive when installing
grinder pump stations in
augured holes where tight
clearances make it difficult to
assure proper backfilling and

compaction with dry materials.
Flowable fills should not be
dropped with more than 4
feet between the discharge
nozzle and the bottom of the
hole because this can cause
separation of the constituent
materials.
7. VENTING: The unit must
be properly vented to assure
correct operation of the pump.
The units are supplied with
a 2" vent opening in the cover
assembly. Failure to properly
vent the tank will result in faulty
operation and will void the
warranty.
If the water level outside
of the station is expected to
rise above the surrounding
grade (flooding), a cover vent
system cannot be used. If
flood conditions are expected,
an underground (lateral) vent
system and solid cover must be
used. Consult the factory if
flood conditions are possible
where the station will be
installed.
8. ELECTRICAL
CONNECTION: (Supply panel
to E/One alarm panel)
Before proceeding, verify that
the service voltage is the same
as the motor voltage shown
on the name plate. An alarm
device is to be installed in a
conspicuous location where
it can be readily seen by the
homeowner. An alarm device is
required on every installation.
There shall be no exceptions.
Wiring of supply panel and
alarm panel shall be per
Figures 2a and 2b, alarm panel
wiring diagrams and local
codes. A dedicated 30 amp
breaker is required before all
simplex alarm panels.
9. ELECTRICAL
CONNECTION: (Pump to
Panel) (Fig. 4) The grinder
pump station is provided
with a cable for connection
between the station and the
alarm panel (supply cable).
The supply cable, a six
conductor tray cable, meets
NEC requirements for direct
burial as long as a minimum of
24" burial depth is maintained.
Those portions of the cable
which have less than 24" of
cover must be contained in
suitable conduit. This includes
the vertical portion dropping
SHROUD
_E
TOR
Power at the station must not drop below 10% of nameplate
voltage. Maximum Recommended Length:
120 Volt 60' (min. voltage at pump — 108V)
240 Volt 150' (min. voltage at pump — 216V)
Consult factory for longer lengths
TYPICAL SUPPLY CABLE CONFIGURATION
to a 24" depth at the station
and the length rising out of the
ground at the control panel.
NOTE: Wiring must be installed
per national and local codes.
Conduit must enter panel from
bottom and be sealed per NEC
section 300.5 & 300.7.
9a. Installing E/One supply
cable:
1) Open the lid of the station
and locate the cable and the
feed -through connector on the
wall of the shroud or on the
inside of the tank wall (Model
WH/WR231 x 55"). Loosen the
nut on the connector and pull
the supply cable out through
the connector until it hits the
crimped on stop feature on the
cable, approximately 36" from
the EQD. **IMPORTANT: All
but 36" of the cable must be
pulled out of the station, and
the EQD and Equalizer should
be hung as high in the station
as possible to ensure that the
pump functions properly. Do
not leave the excess cable in
the station.
2) Retighten the nut. This
connection must be tight or
ground water will enter the
station.
3) Feed the wire through the
length of conduit (contractor
provided), which will protect it
until it is below the 24" burial
depth.
4) On models WHIWR231
x 73" and taller, position the
conduit vertically below the
cable connector along side
of the station reaching down
into the burial depth. Attach
the small protective shroud
provided with the station to
protect the exposed cable
where it enters the station.
Four self -tapping screws are
provided.
5) Run the cable

E/One panel. Leave a 6" to 12"
loop of cable at each end to
allow for shifting and settling.
Connections made at the panel
are shown in the panel wiring
diagram (Figures 2a and 2b).
10. GRINDER PUMP STAND
ASSEMBLY: Temporarily
rest the grinder pump on its
side. Using a block of wood
or similar object, prop up
the lower pump end to allow
installation of the pump stand.
Align the two legs of each
pump stand half with two of
the holes in the pump lower
end (Figure 5). Push the stand
legs into the pump lower end.
Using a mallet, ensure that
the stand legs bottom into the
mounting holes. Repeat for the
other stand half. Turn the pump
upright on the installed stand.
11. DEBRIS REMOVAL:
The incoming sewer line
must be flushed to force all
miscellaneous debris into the
tank. Next, all liquid and debris
must be removed from the
tank. Once the tank is clean,
install the pump.
12. INSTALL THE PUMP:
25
Lower the pump into the
tank. Position the pump so
the pump's discharge is on
the opposite side of the pump
relative to the discharge in
the tank. Position the pump
in the center of the tank.
Rotate to coil the discharge
hose and slide the adapter
on the discharge hose into
the receiver in the tank wall.
Push the white slider down
to open the discharge valve.
See Figures 7 through 10
for slideface connection and
operation.
Hang power cable, Equalizer
and lifting rope to prevent
them from laying in sewage.
Hang the Equalizer as high as
possible in the tank.
13. TEST PROCEDURE:
When the system is complete
and ready for use, the following
steps should be taken to verify
proper pump and high level
alarm operation:
a) Make sure that the
discharge shutoff valve is fully
open. This valve must not
be closed when the pump is
operating. In some installations
there may be a valve, or
valves, at the street main that
must also be open.
(Ignore all Trouble
indications, LEDs and/or
messages until the panel
is reset at the end of this
procedure.)
For model WH231:
b) Turn on the alarm breaker.
c) Fill tank with water until the
high level alarm turns on. Shut
off water.
d) Turn on pump breaker;
the pump should turn on
immediately. Verify that the
high level alarm turns off
and then the pump turns off.
Proceed to Step E.
For model WR231:
b) Fill the tank with 80 gallons
of water. This is approximately
28 inches from the bottom (2 to
3 inches below the top of the
pump).
c) Turn on pump and alarm
breakers; the pump and high
level alarm should turn on
immediately.
d) Verify that the high level
alarm turns off and then the
pump turns off.
e) Clear/Reset the alarm
panel:
Sentry and T260 panels:
Reset is not required.
Protect Panel: Turn pump
and alarm breakers off and
back on simultaneously.
Protect Plus Panels: Perform
a "cold start" from the Initialize
System menu. Any user setting
that were previously chosen
will not be reset.
f) If any Trouble or alarm
conditions are indicated after
the panel is reset, contact your
local service provider.

Lifting Instructions
FAILURE TO FOLLOW THESE INSTRUCTIONS COMPLETELY WILL VOID WARRANTY.
1. Transporting unit to
installation site: Always lift a
unit from the bottom for the
purpose of transportation.
The station should be
received attached to a pallet
for this purpose. Never roll a
station or move it on its side.
2. No Ballast (to be poured in
place): If the concrete anchor is
to be poured while the station
is in place lift the unit using 2
nylon straps wrapped under
the tank flange to make a sling,
as shown below. Keep station
oriented vertically to avoid any
damage.
3. Precast Ballast: Never
lift a station that has a ballast
attached by any means except
the rebar. The weight of the
concrete will damage the
station if you attempt to lift it
from any part of the station.
