23 After the discharge head is installed
on the pump column, always use the
lifting ears on the discharge head for
hoisting the pump. If the discharge head
does not have lifting ears, pass the slings
through the hand holes, taking care that
the slings do not interfere with the shaft.
Never attempt to lift the pump by
means of eyebolts screwed into the
driver mounting holes because the
bolts are not strong enough to carry
the weight of the entire pump.
LEVELING THE PUMP
Remove the supporting timbers,
rope and any other equipment from the
top of the foundation. Cover the
discharge head to protect it from dust,
and sweep the foundation clean.
If the sole plate is not already
grouted in place, be certain that the
grouting dam around the foundation
opening is in place before lowering the
pump assembly onto the foundation.
Lower the pump until the base of
the discharge head or sole plate is just
above the foundation bolts; then orient
the pump so that the discharge outlet is
in the desired direction and the holes in
the base align with the foundation bolts.
Continue to lower the pump until the
bolts just enter the holes in the base.
If the foundation is concrete, place
the wedges (furnished with the pump)
under the discharge head or sole plate,
adjacent to the bolt holes, one under
each of the four sides. For structural
foundations (made up of I-beams or Hbeams), use flat shims under the corners.
Continue to slowly lower the pump
until the base of the discharge head or
sole plate rests on the shims or anchor
bolts with washers and nuts.
Accurate alignment of the discharge
head in relation to the pump shaft is
absolutely essential for a smoothlyoperating and trouble free pumping system.
By using the wedges or washers and
nuts on the anchor bolts, adjust the
discharge head flange centerline to the
correct elevation.
While maintaining the correct
elevation, adjust the nuts and washers or
shims to achieve the specified levelness
(0.0005" per foot) in both directions, as
shown in Figure 16. The levelness
should be measured by placing a
precision level on the machined face of
the discharge head motor register.
Figure 16. Check for levelness in two
directions.
14.D
24 Never attempt to align the
discharge head using a spirit
(carpenter’s) level. If the pump
column does not hang freely in the
well, as might be the case when the
well is drilled at a slight slant, leveling
the discharge head will not insure the
necessary shaft alignment and
clearance in the driver spindle. The
discharge head base must be square
with the pump shaft regardless of the
result indicated by a spirit level. A
bent shaft could occur, causing early
pump failure and expensive repair.
Place a machinist's level on the
driver mounting surface of the discharge
head, orienting it parallel with one of the
edges of the base. Move the wedges or
add more shims as necessary until the
level reading reaches 0.0005" per foot.
Reorient the level on the same
surface, 90º from the original position.
Again adjust the wedges or shims until a
0.0005" level reading is reached, taking
care not to upset the levelness is the first
direction. After each adjustment, check
for levelness in both directions. Push in
or add to any loose shims to distribute
the weight evenly. The discharge head
must be level within 0.0005" with all
wedges or shims bearing tightly against
the base or sole plate.
Install nuts on the foundation bolts
and tighten them gradually and
uniformly. Re-check the level readings
in both directions. If necessary, loosen
the foundation bolts and re-adjust the
wedges or shims, tighten the bolts again
and re-check the level readings.
GROUTING THE DISCHARGE HEAD/SOLE PLATE
After the discharge head is at the
correct location and leveled with a
precision level, the discharge head
and/or sole plate need to be grouted to
the foundation.
Use only non-shrinking grouting
material for grouting the discharge head/
sole plate to the foundation.
Build a dam on the foundation,
enclosing an area around the discharge
head that includes all of the alignment
wedges. The top of the dam should be
approximately ½ inch above the bottom
of the discharge head base (see Figs. 1a
and 1b on page 6).
Pour the grouting material into the
dammed-in area, and force it between
the discharge head and the foundation all
around. Level off the grout flush with
the top of the dam. Allow the grout to
cure at least 48 hours before tightening
the foundation bolts or starting the
pump.
14.D
25 TENSIONING THE TUBE NUT
The enclosing tube sags slightly
from its own weight as it is installed, and
must be pulled tight (tensioned) to make
it straight. The tube nut (see Fig. 15)
holds the tube in its straightened
position. This section describes two
methods of tensioning the tube. The
second method (the “wrenching
method”) is given as an alternative for
use with pumps having settings less than
500 feet.
Note: The correct tension is the
weight of the enclosing tube plus 10%.
Weights-per-foot for each tube size
are given in Table 2. Multiply by the
total length of tube to determine the total
weight.
Table 2. Weight per Foot of
Enclosing Tube
Tube size (in.) Weight per foot
(lb.)
1 ¼ 2.99
1 ½ 3.63
2 5.02
2 ½ 7.66
3 10.25
3 ½ 12.50
4 14.98
5 20.78
6 28.57
Apply a generous coating of grease
to both sides of the gasket and place the
gasket on the discharge head. Install the
tube nut, screwing it down manually
until its shoulder rests firmly on the
gasket.
The upper end of the tube may be
pulled by the hoist to obtain the
predetermined tension value. This
requires the use of a dynamometer scale
and a specially-made fitting to grip the
tube. The fitting may be a short tube
with welded-on lugs for gripping with a
sling and an internal thread to mate with
the tube thread.
Figure 17. Typical tube nut assembly.
14.D
26 With the tube nut installed manually
but not tightened, screw the special
fitting onto the top of the tube to its full
engagement. Attach the dynamometer
scale to the lugs, and connect the upper
end of the scale to the hoist hook (see
Fig. 18). Operate the hoist to apply the
required tension. This will pull the tube
nut up off the gasket. Manually screw
down the tube nut to reseat it. Reduce
the tension to zero. Remove the
dynamometer scale and the special
fitting.
If a dynamometer scale is not
available, the tube can be tensioned by
wrenching the tube nut. This is
permissible only for pumps with
settings under 500 feet. A special
wrench for tightening the tube nut may
be obtained from the dealer. Apply the
special wrench to the tube nut so that the
slots in the wrench engage the lugs at the
top of the tube nut. Using chain tongs
strapped around the special wrench, turn
the tube nut to take all of the slack out of
the tube and induce a reasonable amount
of tension in it. The tube nut is properly
torqued if it forms an effective seal with
the gasket. This can only be determined
when the pump is started (see Starting
the Pump on page 40).
Insert the two packings (see Fig. 17)
into the recess in the tube nut. Screw the
packing follower on the tube threads,
tightening it firmly against the packings.
Use the small end of the special tube nut
wrench and a pipe wrench to turn the
follower.
Place the tube nut cap in position
over the tube nut and fasten it to the
discharge head with the cap screws
provided.
Figure18. Tensioning the tube nut.
14.D
27 INSTALLING THE VERTICAL HOLLOW SHAFT (VHS) MOTOR
On pumps with twopiece top shafts, the top shaft
should not be installed yet.
The head shaft threads and
face should be checked for
any nicks or burrs. If any are
found, correct them with the
use of a mill file. Fig. 19
shows a typical motor; refer
to manufacturer instructions
for proper dimensions and
installation. These instructtions are offered as guidelines only.
Clean the coupling
threads with a wire brush and
solvent. Coat the threads and
face of the coupling with
anti-seize compound.
Screw the coupling on
until its center hole is in line
with the face of the head
shaft. Cover the coupling top
opening with plastic or a
clean rag to prevent the entry
of any foreign material into
the coupling while the motor
is being lowered into
position.
If the pump is
constructed with a one-piece top
shaft, care must be taken when
lowering the motor onto the
discharge head, to prevent it from
bumping against the top shaft
protruding above the discharge head.
Any contact of the motor with the onepiece top shaft could result in bending of the shaft.
Figure 19. Typical motor construction; refer to assembly drawing and information provided by the motor
manufacturer for details on your particular motor.
14.D
28 Prior to removing the top drive
coupling hub from the motor rotor, be
sure to scribe a line with a marking pen
(match mark) on the drive hub location
and the rotor.
Remove the bolts holding the top
drive coupling and lift it off. On larger
motors, the top drive coupling may be of
such size and weight that an overhead
crane and eyebolts (screwed into the
coupling for lifting) will be required to
move the coupling.
On one-piece top shaft construction,
lower the motor slowly, aligning the
axial hole of the hollow shaft with the
top shaft so that there will be no
bumping as the shaft enters and passes
through the motor hollow shaft.
Place the motor mounting bolts into
the holes of the motor end bell. Lower
the motor until it is approximately ¼" to
⅜" away from the discharge flange face.
Orient the motor with the conduit box in
the desired position and the mounting
holes aligned with the mating tapped
holes in the discharge head.
Do not work under a heavy
suspended object unless there is a
positive support
under it to stop its
fall in even of sling
or hoist failure.
Disregard of this
warning could result
in grave personal
injury.
At this time, engage the motor
mounting bolts in the tapped holes of the
discharge head. This will help align the
motor register to the discharge register.
Prior to lowering the motor onto the
register, check to make sure no foreign
material has gotten between the motor
and discharge head faces.
When lowering the motor to the
pump, take care not to bump or
scrape against the top shaft
protruding above the discharge head.
This could result in bending of the
shaft.
Lower the motor until the registers
engage and the motor rests firmly on the
discharge head. Tighten the motor
mounting bolts that have already been
engaged.
If the pump has a head shaft just
below the top shaft, only the head shaft
will be installed at this time. The top
shaft will be inserted through the motor
later, after the motor has been tested for
direction of rotation.
Match mark the top drive coupling
relative to the motor rotor. Remove the
bolts holding the top
drive coupling, and
lift it off. On larger
motors, the top drive
coupling may be of
such size and weight
that an overhead
crane and eyebolts (to
screw into the top
drive coupling) will
be required to move
the coupling.
14.D
29 Check the threads and faces of the
bottom of the top shaft for any nicks or
burrs, and correct as required. Wire
brush and clean the threads with solvent.
Coat the threads and face with anti-seize
compound.
Lift the top shaft up and center it in
the hollow shaft of the motor prior to
lowering it. Lower it slowly through the
motor hollow shaft.
As the lower end of the shaft comes
out the bottom of the motor hollow shaft,
check for any foreign material on the
face and threads of the shaft that may
have been picked up while the shaft was
being lowered.
Prior to lowering the shaft into the
coupling, remove the protective plastic
or cloth. Check to be sure the coupling
center hole is still at the face of the head
shaft.
While holding the coupling in place,
screw the top shaft into the coupling
until the faces mate. Approximately the
same number of threads should be
exposed outside the coupling on both
ends, if the coupling is properly
centered.
With the top shaft tightened to the
head shaft, go to the top of the motor and
check to see if the top shaft is concentric
with the motor hollow shaft, and that the
motor shaft rotates freely when turned
by hand.
If the top shaft is not concentric
with the hollow shaft of the motor,
determine the cause of the eccentricity.
Eccentricity may be due to a bent shaft
section or to misalignment caused by
foreign particles between butting ends of
shaft sections or between the discharge
head and column flange.
Mark where the shaft is leaning
toward the motor hollow shaft, lift up on
the pump shaft, and rotate it 180°. If the
lean follows the rotation of the shaft, it is
due either to a defective coupling or a
bent shaft. If the lean remains at the
same location, it would be due to
eccentricity or “out-of-squareness” of
the mating surfaces of the discharge
head and column. If either condition
exists, it must be investigated and
corrected prior to proceeding with the
installation.
Prior to energizing the motor for
rotation check, be sure the motor has
been properly lubricated as per the
manufacturer’s instructions.
If the motor is oil lubricated, the
drain plug should be removed and a
sample of the oil inspected for
condensation or foreign material. If any
contaminants or condensation is found in
the oil sample, the oil reservoir needs to
be flushed with clean oil until all
evidence of contamination is removed.
Replace the drain plug and fill the oil
reservoir in accordance with
manufacturer’s specifications for type
and quantity of oil.
Make temporary wiring connections
to the motor. The motor voltage rating is
given on the nameplate. DO NOT USE
ANY OTHER VOLTAGE.
The motor can now be checked for
proper rotation (counter-clockwise,
when viewed from above). When
checking direction of rotation, simply
“bump” the power; do not hold the
switch closed.
14.D
30 Motors having spring-loaded
spherical roller bearings must not be
allowed to run at normal speed
without a load. When checking
direction of rotating, do not hold the
switch closed—just “tap” it.
If the direction of rotation is not
correct, reverse it by changing the wiring
connections to the motor. For a threephase motor, interchange any two of the three leads. If the motor is single-phase,
directions for reversing rotation are
given on the nameplate. MARK THE
LEADS TO INDICATE THE
CORRECT CONNECTIONS.
The motor must not be tested for
direction of rotation when coupled to
the pump. If the pump should rotate
in the wrong direction, serious
damage to the pump and motor and
grave injury to nearby personnel
could result.
Once the motor rotation is
confirmed to be correct, make the final
electrical connections to the motor. All
connections must be insulated in
accordance with local electrical codes.
At this time the top drive coupling
can be reinstalled in its original location,
using anti-seize compound on the
registers between the top drive coupling
and the motor rotor.
14.D
31 INSTALLATION OF LUBRICATION SYSTEM
The oil reservoir may be integral
with the discharge head or it may be a
separate tank. Inspect the inside of the
reservoir for cleanliness. If necessary,
flush it out with petroleum-base solvent
(if permissible by local EPA codes).
If a separate tank is supplied with
the pump, attach it to the side of the
discharge head, using the brackets and
cap screws provided.
The oil system from the reservoir to
the pump is depicted in Fig. 20. Connect
the solenoid valve (if used) and the sight
feed oil valve (either plain or
temperature-compensated) to the
reservoir as shown in the appropriate
figure. Connect a short length of tubing
from the bottom of the sight feed oil
valve to the ¼ NPT hole in the side of
the tube nut cap.
The solenoid valve is designed to
open, permitting oil to flow, whenever
the pump driver is started. The voltage
rating of the solenoid valve is shown on
the nameplate. Do not use any other
voltage.
If the pump is to be motor-driven
and the correct voltage for the solenoid
is available at the motor, connect the two
solenoid leads to any two motor leads
having the correct voltage. If the motor
voltage is too high, the solenoid may be
wired to suitable low voltage taps at the
control panel, or a separate transformer
may be used.
Use only high quality turbine oil. A
list of acceptable oils is given in Table
3b. Fill the reservoir with oil. Adjust the
sight feed oil valve for a flow of 5 to 6
drops per minute for each hundred feet
of pump depth. After two weeks of
operation, reduce the flow to
approximately 3 drops per minute for
each hundred feet.
Keep the reservoir cover tightly in
place at all times to prevent entry of dirt
into the oil system. Maintain the oil level
in the reservoir at least one-quarter full.

35 IMPELLER CLEARANCE ADJUSTMENT
Lock out the electrical power
source before working on the pump.
With the top drive coupling securely
fastened to the motor rotor, check the gib
key fit to the top shaft keyway. The key
fit should be such that one can slide the
key inside the shaft keyway by hand.
Rotate the top drive coupling until
its keyway is aligned with the top shaft
keyway. The key must fit snugly against
the sides of the keyways, but must have
a slight clearance with the bottom of
each keyway. File the key, if necessary,
with a smooth mill file to obtain the
proper fit. Coat the gib key with antiseize compound and install in keyway (see Fig. 21).
Prior to installing the brass adjusting
nut, take a marking pen and scribe radial
marks from of all the drilled and tapped
holes to the outside circumference.
These marks will allow you to more
easily locate the holes after the top
adjusting nut is installed.
At this time, attempt to manually
rotate the pump and motor counterclockwise. No rotation should be possible if all the threaded line shaft is
mated and the impeller is resting on the
suction manifold. If any free rotation of
the pump and motor can be made, it is an
indication that the line shaft has come
unscrewed. If possible, try to determine
the location of the loose line shaft. If this
is not possible, continue to rotate the
pump and motor counter-clockwise until
it stops.
On small pumps at short settings
where the rotating element of the pump
is relatively light, rotation of the shaft
may be felt but some resistance would
be encountered (shaft would not freely
spin).
Install the brass adjusting nut on the
top shaft and screw down until it makes
light contact with the face of the top
drive coupling. Do not tighten yet.
Measure the distance from the face
of the motor top drive coupling to the
top of the top shaft. Record this
measurement.
Turn the adjusting nut in a righthand rotation until the dimension that was recorded is increased by 3/16", or
by the recommended impeller clearance
as shown in Table 4 on pps. 37-39 (see
Fig. 21). After the pump has operated for
a minimum of one hour, or when the
water is clear of foreign material, the
impeller clearance can be reset if so
desired, but this is not required for
normal pump operation.
Figure 21. Gib key inserted into top shaft and
top drive coupling.
14.D
36 A pump operating in a new well or
sump should be run with its impellers in
the mid-position, which is approximately
3/16 inch above the lateral bowl wear
rings. This is to minimize the possibility
of damage due to sand in the water.
When the water is clear of sand, the
impellers should be reset to the most
efficient pumping position.
Verify free rotation of pump-motor
shaft. It should rotate by hand freely.
Align the holes in the adjusting nut with
the radial marks indicating the location
of the tapped holes in the top drive
coupling.
Turn the nut slightly in either
direction, if necessary, to align two of
the holes 180° apart in the adjusting nut
with the tapped holes in the top drive
coupling.
Install the adjusting nut retaining
bolts and tighten.
Replace the motor canopy prior to
putting the pump in operation.
Note: The impellers must be
adjusted before any attempt is made
to start the pump.
After freedom of rotation is verified,
the lock out on the electrical power
should be removed and the pump is now
ready for start-up.
The driver cover must be in place
when the pump is in operation.
Rotating parts below this cover could
cause grave personal injury if
exposed.

40 STARTING THE PUMP
Before attempting to start the pump,
check the water level in the well or sump
to be sure that the first impeller of the
pump is submerged. Do not operate the
pump if the first impeller is above the
standing water level. In this condition,
the pump cannot be expected to pump
water, and severe damage to the pump
may result.
Before attempting to start the pump,
check the readiness of the following
items:
Level of oil in the reservoir
Lubrication of
the driver
Oil-cooling
connections for
the driver (if
applicable)
Wiring of
electric motor
(if applicable)
Impeller
adjustment
Discharge
piping
connection
Shut-off valve in discharge pipe –
should be ¼ open
Allow the sight valve to operate for
approximately ½ hour before starting the
pump. This is especially important if the
pump has been sitting idle for some time
after installation.
If the pump does not discharge air
or fluid immediately after start-up, shut
it down.
For pumps in which the enclosing
tube was tensioned by wrenching the
tube nut, check for leakage at the tube
nut gasket. If the gasket does not seal
properly, the tube nut must be tightened.
With the pump shut down, work through
the hand holes to tighten the tube nut to
ensure adequate seal at the gasket.
After the pump is started, check for
any unusual noises and excessive
vibration. If either is present, shut the
pump down and investigate the cause of
the problem.
If the pump is
started with the
check valve open
and the pump is
operating against
the system head,
slowly open the
discharge valve
until the pump is
operating at its
designed discharge pressure. If
the system head
was correctly
calculated, the pump should operate at
its design condition with the discharge
valve completely open.
Operation of the pump away from
its intended design conditions could
have adverse effects on its efficiency and
service life.

SAFETY FIRST!
High voltage and rotating parts can cause serious injury or loss of life. Installation, operation and maintenance must be performed by qualified personnel. Familiarization with and adherence to NEMA† MG2, the National Electric Code, and local codes is recommended. It is important to observe safety precautions to protect personnel from possible injury. Personnel should be instructed to:
1. Disconnect all power to motor and accessories prior to initiating any installation, maintenance or repairs. Also ensure that driven equipment connected to the motor shaft will not cause the motor to rotate (windmilling of fans, water flowing back through pump, etc.).
2. Avoid contact with rotating parts.
3. Act with care in accordance with this manual’s prescribed procedures in handling and installing this equipment.
4. Be sure unit and accessories are electrically grounded and proper electrical installation wiring and controls are used in accordance with local and national electrical codes. Refer to “National Electrical Code Handbook” – NFPA No. 70. Employ qualified electricians.
5. Be sure equipment is properly enclosed to prevent access by children or other unauthorized personnel in order to prevent possible accidents.
6. Be sure shaft key is fully captive before unit is energized.
7. Provide proper safeguards for personnel against rotating parts and applications involving high inertia loads, which cause overspeed.
8. Avoid extended exposure to equipment with high noise levels.
9. Observe good safety habits at all times and use care to avoid injury to yourself or damage to equipment.
10. Be familiar with the equipment and read all instructions thoroughly before installing or working on equipment.
11. Observe all special instructions attached to the equipment. Remove shipping fixtures, if so equipped, before energizing unit.
12. Check motor and driven equipment for proper rotation and phase sequence prior to coupling. Also check if a unidirectional motor is supplied and note proper rotation.
13. Electric motors can retain a lethal charge even after being shut off. Certain accessories (space heaters, etc.) are normally energized when the motor is turned off. Other accessories such as power factor correction capacitors, surge capacitors, etc. can retain an electrical charge after being shut off and disconnected.
14. Do not apply power correction capacitors to motors rated for operation with variable frequency drives.
Serious damage to the drive will result if capacitors are placed between the motor and drive. Consult drive supplier for further information.

1. SHIPMENT
Prior to shipment, all TITAN Line Motors undergo extensive electrical and mechanical testing, and are thoroughly inspected. Upon receipt of the motor, carefully inspect the unit for any signs of damage that may have occurred during shipment. Should such damage be evident, unpack the motor at once in the presence of a claims adjuster and immediately report all damage and breakage to the transportation company and Nidec Motor Corporation.
When contacting Nidec Motor Corporation concerning the motor, be sure to include the complete motor identification number, frame and type which appears on the nameplate (see installation record in this manual).
2. HANDLING
The equipment needed to handle the motor includes a hoist and spreader bar arrangement of sufficient strength to lift the motor safely. The spreader bar arrangement should be employed whenever multiple lifting lugs or eyebolts are provided (See Figure 1A & 1B.) The spreader bar should have the lifting hooks positioned to equal the span of the eyebolts or lifting lugs. The eyebolts or lifting lugs provided are intended to lift the motor weight only. See Table 7 for motor weights.

3. STORAGE
3.1 When to put a Motor in Storage.
If a motor is not put into immediate service (one month or less), or it is taken out of service for a prolonged period, special storage precautions should be taken to prevent damage. The following schedule is recommended as a guide to determine storage needs.
A. Out of service or in storage less than one month – no special precautions except that space heaters, if supplied, must be energized at any time the motor is not running.
B. Out of service or in storage for more than one month but less than six months – store per Section 3.2 A, B, C, D, E, F (2) and G, Section 3.3 A, B and C, and Section 3.4.
C. Out of service or in storage for six months or more – all recommendations.
3.2 Storage Preparation
A. Where possible, motors should be stored indoors in a clean, dry area.
B. When indoor storage is not possible, the motors must be covered with a tarpaulin. This cover should extend to the ground; however, it should not tightly wrap the motor. This will allow the captive air space to breathe, minimizing formation of condensation. Care must also be taken to protect the motor from flooding or from harmful chemical vapors.
C. Whether indoors or out, the area of storage should be free from excessive ambient vibration which can cause bearing damage.
D. Precautions should be taken to prevent rodents, snakes, birds or other small animals from nesting inside the motors. In areas where they are prevalent, precautions must be taken to prevent insects, such as dauber wasps, from gaining access to the interior of the motor.
E. Inspect the rust preventative coating on all external machined surfaces, including shaft extensions. If necessary, re-coat the surfaces with a rust preventative material, such as RUST VETO† No. 342 (manufactured by E.F. Houghton Co.) or an equivalent. The condition of the coating should be checked periodically and surface re-coated as necessary.
F. Bearings:
(1) When storage time is six months or more, grease lubricated cavities must be completely filled with lubricant. Remove the drain plug and fill cavity with grease until grease begins to purge from drain opening. Refer to Section 7.5 and/or review motor’s lubrication nameplate for correct lubricant.
Immediately remove any shrink wrap used during shipping. Never wrap any motor in plastic for storage. This can turn the motor into a moisture trap causing severe damage not cover by Nidec Motor Corporation warranty

14.D
5 INSTALLATION AND MAINTENANCE

(2) Oil lubricated motors are shipped without oil. When storage time exceeds one (1) month, the oil sumps must be filled to the maximum capacity as indicated on the oil chamber sight gauge window. Refer to motor lubrication nameplate or Table 5 for proper oil.
NOTE: Motor must not be moved with oil in reservoir. Drain oil before moving to prevent sloshing and possible damage. With a clean cloth, wipe any excess oil from the threads of the drain plug and the inside of the drain hole. Apply GASOILA† or equivalent thread sealant to the threads of the drain plug and replace the plug in the oil drain hole. Refill oil when motor has been moved to the new location.
G. To prevent moisture accumulation, some form of heating must be utilized. This heating should maintain the winding temperature at approximately 5°C above ambient. If space heaters are supplied, they should be energized. If none are available, single phase or ‘trickle’ heating may be utilized by energizing one phase of the motor’s winding with a low voltage.
Request the required voltage and transformer capacity from Nidec Motor Corporation. A third option is to use an auxiliary heat source and keep the winding warm by either convection or blowing filtered warm air into the motor.
3.3 Periodic Maintenance
A. Oil should be inspected monthly for evidence of moisture or oxidation. The oil must be replaced whenever contamination is noted or every twelve months; which ever occurs first. It is important to wipe excess oil from the threads of the drain plug and the drain hole and to coat the threads with GASOILA† or equivalent thread sealant before replacing the drain plug.
B. Grease lubricated bearings must be inspected once a month for moisture and oxidation by purging a small quantity of grease through the drain. If any contamination is present, the grease must be completely removed and replaced.
C. All motors must have the shaft rotated once a month to maintain a lubricant film on the bearing races and journals.
D. Insulation Testing:
Two tests are used to evaluate the condition of the winding insulation. The first of these is the one minute insulation resistance test (IR1) and the second is the polarization index test (PI), which can also be referred to as a dielectric absorption test. The results of either of these tests can be skewed by factors such as the winding temperature and its relation to the dew point temperature at the time the test was conducted. The PI test is less sensitive to these factors than the IR1 test, but its results can still be affected significantly. Due to these factors, the most reliable method for evaluating the condition of the winding insulation is to maintain a record of periodic measurements, accumulated over months or years of service, for one or both of these tests. It is important that these tests be conducted under similar conditions of winding temperature, dew point temperature, voltage magnitude and duration, and relative humidity. If a downward trend develops in the historical data for either test, or if the readings from both tests drop below a minimum acceptable value, have an authorized electrical apparatus service shop thoroughly clean and dry the winding, and retreat, if necessary.

14.D
6 INSTALLATION AND MAINTENANCE
www.usmotors.com Nidec Motor Corporation
The recommended procedure for the IR1 test is as follows:
(1) Disconnect all external accessories or equipment that have leads connected to the winding and connect them to a common ground. Connect all other accessories that are in contact with the winding to a common ground.
(2) Using a megohmmeter, apply DC voltage at the level noted below for 1 minute and take a reading of the insulation resistance between the motor leads and ground. (3) The reading should be corrected to a 40○C base temperature by utilizing the formula:
R40C = KTRT
Where:
R40C = insulation resistance (in megohms) corrected to 40○C KT = insulation resistance temperature coefficient at temperature T○C RT = measured insulation resistance (in megohms) at temperature T○C The value of KT can be approximated by using the formula:
KT = (0.5)(40 – T)/10
Where:

(2) With DC voltage still being applied by the megohmmeter, take an additional reading of insulation resistance between the motor leads and ground 10 minutes after the DC voltage was initially applied. To minimize measurement errors, the variation in winding temperature between the 1 minute and 10 minute readings should be kept to a minimum.
(3) Obtain the polarization index by taking the ratio of the 10 minute resistance reading to the 1 minute resistance reading.
If historical data from previous IR1 and / or PI tests is available, then a comparison of the present test result to previous tests can be used to evaluate the condition of the insulation. To minimize error, all readings that are compared should be taken at test voltages, winding temperatures, dew point temperatures, and relative humidities that are as similar as possible.
If a downward trend in the readings develops over time, have an authorized electrical apparatus service shop thoroughly clean and dry the winding and, if necessary, retreat the winding. Then, repeat the tests and re-check results before returning the motor to service.
If historical data from previous IR1 or PI tests is not available, then compare readings from the present test to the recommended minimum values listed below. If the readings from both tests fall below the minimum, have an authorized electrical apparatus service shop thoroughly clean and dry the winding and, if necessary, retreat the winding. Then, repeat the tests and re-check results before returning the motor to service.
The recommended minimum value for the 1 minute insulation resistance reading corrected to 40○C is:
The recommended minimum value for the polarization index is 2.0. If the 1 minute insulation resistance reading corrected to 40 ○C is above 5000 megohms, however, the polarization index may not be meaningful. In such cases, the polarization index may be disregarded as a measure of insulation condition.
Refer any questions to the Nidec Motor Corporation Product Service Department.

4. INSTALLATION LOCATION
When selecting a location for the motor and driven unit, keep the following items in mind.
The location should be clean, dry, well ventilated, properly drained and provide accessibility for inspection, lubrication and maintenance. Ambient vibration should be kept to a minimum. Outdoor installations on Open Dripproof motors require protection from the elements.
The location should also provide adequate space for motor removal without shifting the driven unit.
The temperature rise of a standard motor is based on operation at an altitude not higher than 3,300 feet above sea level and a maximum ambient temperature of 40°C. See NEMA MG-1 20.28 for usual service condition.
To avoid condensation inside of motor, motors should not be stored or operated in areas subject to rapid temperature changes unless they are energized or protected by space heaters.
The motor should not be installed in close proximity to any combustible material or where flammable gases and/or dust may be present, unless motor is specifically built for that environment and is labeled accordingly.
Recommended Minimum Installation Clearances
This is a general guide and cannot cover all circumstances. Unusual arrangements should have inquiries to Nidec Motor Corporation Product Service Department. Unusual arrangements might include high ambient, limited ventilation, or a large number of motors in a confined space. The distance to the wall is at the side or end of the motor. The distance to another motor is considered as surface to surface and for side-by-side arrangements. This recommendation considers all motors to be mounted in the same orientation (e.g. all main conduit boxes facing east).

5. FOUNDATION
Concrete (reinforced as required) makes the best foundation, particularly for large motors and driven units. A sufficient mass provides rigid support that minimizes deflection and vibration. It may be located on soil, structural steel or building floors, provided that the total weight (motor, driven unit and foundation) does not exceed the allowable bearing support. (Allowable bearing loads of structural steel and floors can be obtained from engineering handbooks. Building codes of local communities give the recommended allowable bearing loads of different types of soil.) It is recommended that a fabricated steel base (sole plate) be used between the motor and the foundation. See Figure 2. Base foot pads should be level and in the same plane.

5.1 Grouting
Grouting is the process of firmly securing equipment to a concrete base. This base is a continuation of the main foundation, designed to dampen any machine vibration present and prevent the equipment from shaking loose during operation. A serviceable and solid foundation can be laid only by careful attention to proper grouting procedure.
In practical terms ‘grout’ is a plastic filler that is poured between the motor sole plate and the foundation upon which it is to operate. Being plastic, it is expected to fill all spaces and cavities before it sets or solidifies and becomes an integral part of the principal foundation. In order to function properly, the principal foundation should be allowed to fully set through chemical reaction and dehydration as recommended by the grout manufacturer, prior to motor installation.
6. INITIAL INSTALLATION
6.1. Coupling or Pulley Installation
Remove the shaft clamping device shipped on the motor (as applicable). Do not discard the clamping device as it will be needed should the motor require transport in the future. Wash protective coating from the motor shaft extension(s) with solvent. Install couplings or pulleys on motor shaft per manufacturers’ recommended fit and mounting practices.

In belted applications, the driver pulley should be positioned as close to the shaft shoulder as possible to assure longest bearing life and keep shaft bending moment to a minimum. Take care to ensure that the inboard edge of the pulley hub does not ride-up on the shaft shoulder blend radius.
6.2 Rough Alignment
Inspect sole plate mounting pads and bottom of motor feet for dirt or irregularities that would prevent proper seating.
Position and shim the motor such that the coupling hubs are aligned within 1/32 inch and the motor shaft is level. The motor shaft must be slightly lower than the driven shaft to allow for final adjustment shims. Shims and support mounting should provide support under the entire foot area.
6.3 Final Alignment
Accurate shaft alignment between motor and driven equipment is essential for trouble-free operation. Improper alignment can result in vibration, bearing overload and excessive shaft stresses. Flexible couplings may not adequately compensate for excessive misalignment.
Whenever aligning a motor to driven equipment, keep the following rules in mind:
- Do not place more than five shims in a shim pack under any one machine foot, as flexibility of the shim pack will contribute to a soft foot condition. - After any corrective adjustment, tighten foot bolts securely and recheck alignment. - When making shim adjustments, change only one foot at a time.
For units with Sleeve Bearings:
Sleeve bearing motors should be direct-coupled to the driven equipment. See coupling recommendations for recommended coupling type. Never use a pulley or sprocket as they transmit unacceptable radial loads to the motor bearings. ! CAUTION
For units with Antifriction Bearings:
Belt tension should not exceed the transmission drive manufacturers' recommendations.
Excessive belt tension reduces belt life. Overload due to over tensioning of belts reduces bearing life and can induce shaft fatigue failure.
Excessive bending movement due to placing of pulley far out on shaft extension will reduce bearing life and may lead to shaft fatigue failure.
Placing the pulley hub onto the shaft against the shaft shoulder blend radius may cause a large stress riser in the shaft, resulting in shaft fatigue failure. Prevent this from occurring by using a chamfered spacer ring or by chamfering the end of the hub bore. ! CAUTION

- Recheck alignment after the motor has been in service for approximately one week and readjust as necessary.
A. Angular Alignment (See Figure 3A)
Check for angular misalignment of motor to driven unit shaft. (See Figure 3A). Measure distance between coupling hub faces (with feeler gauges) at four places equally spaced around the outside diameters. Position motor as necessary to be within the maximum allowable misalignment of .001 inch per foot of coupling radius.
B. Parallel Alignment (See Figure 3B)
Fasten a dial indicator onto one coupling hub with the indicator button on the cylindrical surface of the opposite coupling hub. Rotate shafts together and take readings at four points, 90° apart.
Relocate motor until total indicator movement in full rotation does not exceed .002 inch. Transfer indicator to opposite hub and repeat the parallel alignment procedure. Recheck angular alignment as described in Step A.
FIGURE 3
FLEXIBLE COUPLINGS
C. Soft Foot Check
Check and correct any ‘soft foot’ condition to assure that equal pressure is exerted on each motor foot by the following shimming procedure. Bolt all motor feet down solidly to the motor bedplate or foundation. Mount the base of the dial indicator on the motor’s foundation, and place and zero out the indicator on the motor shaft or coupling. Back off one of the drive end mounting bolts and check indicator for change in reading. Change should not exceed .001 inch. Shim at foot if required and go to other take-off end bolt. This procedure should be repeated on the opposite end until no reading is greater than .001 inch.
D. Hot Alignment
It is possible for the motor shaft height to change relative to the driven equipment and this should be compensated for during the alignment procedure. Recheck parallel alignment (vertical) of Initial

coupled drive by repeating after normal operating temperature is reached. If shimming is changed, repeat alignment procedure to the extent necessary to assure proper alignment.
6.4 Coupling Requirements
Standard sleeve bearing motors are not designed to withstand axial thrust loads. Machines that are to be driven by motors with sleeve bearings should be designed to take all the thrust load.
The driven equipment shaft should have its axial end play limited as necessary to prevent applying any axial load to the motor sleeve bearings.
Operating experience on horizontal sleeve bearing motors has shown that sufficient thrust to damage bearings may be transmitted to the motor through some flexible couplings. This requires that a limited end float coupling, in accordance with the following is used.
A. Gear Type D. Roller Chain Type
B. Tapered Grid Type E. Rubber Biscuit Type
C. Disk Type with Positive Stops

6.5 Electrical Connection
Refer to the motor nameplate for power supply requirements and to the connection diagram for connection parameters. Be sure connections are tight. Recheck carefully and assure that they agree with the connection diagram. Insulate all connections to insure that they will not short against each other or to ground. Be sure the motor is grounded to guard against electrical shock.
Refer to the National Electrical Code Handbook (NFPA No. 70) and to local electrical codes for proper wiring, protection and wire sizing. Be sure proper starting equipment and protective devices are used for every motor. For assistance, contact the motor starter manufacturer. Apply the above precautions to all accessories as well.
6.6 Reversing Rotation
The direction of rotation may be reversed by interchanging any two of the three power phases to the motor leads. Be sure that the power is off and steps are taken to prevent accidental starting of the motor before attempting to change any electrical connections.
6.7 Initial Start
After installation is completed, but before motor is put in regular service, make an initial start as follows:
A. Insure that motor and control device connections agree with wiring diagrams.
B. Insure that voltage, phase and frequency of line circuit (power supply) agree with motor nameplate.
C. Check insulation resistance according to Section 3 ‘Storage’, Part 3.3.
Some motors have unidirectional ventilating fans. Running such a unit in reverse for any extended length of time will result in motor damage. On motors that are unidirectional, the direction of rotation is noted by an arrow mounted on the motor and by a warning plate mounted near the main nameplate. To determine direction of rotation for which leads are connected, apply power momentarily and observe rotation. Motor should be uncoupled from driven equipment to insure driven equipment is not damaged by reverse rotation. Motor coupling may require removal or support if motor is operated uncoupled from driven equipment.

E. If motor has been in storage, either before or after installation, refer to Section 3 ‘Storage’, Part 3.4.
F. Check for proper or desired rotation. See Part 6.6 of this section.
G. Insure that all protective devices are connected and are operating properly.
H. Check sleeve bearing housings to be certain that they have been filled to the ‘MAX’ level with the correct lubricant recommended in the instruction manual and lubrication plate.
I. Run motor at minimum possible load long enough to be certain that no unusual condition develops. Listen and feel for excessive noise, vibration, clicking or pounding. If any are present, stop motor immediately. Investigate the cause and correct before putting motor into service. In the case of vibration, see Part 6.8 of this section.
J. When checks are satisfactory to this point, increase the load slowly up to rated load and check unit for satisfactory operation.
6.8 Vibration
Motors are supplied as standard in accordance with NEMA MG-1, Section 7, which dictates that the motor no-load vibration when mounted on a resilient base shall not exceed the limits as outlined in the following table:
TABLE 2
NO-LOAD VIBRATION LIMITS
Speed, RPM Rotational Frequency, Hz

6.9 Doweling
Doweling the motor (and driven unit) accomplishes the following:
- Restricts movement of the motor and driven unit.
- Eases realignment if motor is removed from base.
- Temporarily restrains the motor, should mounting bolts loosen.
The following procedure for inserting dowel pins is recommended.
A. Check the alignment after the unit has been operational approximately one week. Correct if necessary.
B. Drill through motor feet on drive end and into base. Use holes in motor feet (if provided) as a pilot. Drill diameter must be slightly smaller than the intended dowel size to allow for reaming operation.
C. Ream holes in the feet and base to the proper diameter for the pins (light press fit).
D. Insert dowel pins.
7. ROUTINE MAINTENANCE
Start the motor in accordance with the standard instructions for the starting equipment used. Connected load should be reduced to the minimum, particularly for reduced voltage starting and/or high inertia connected loads, until the unit has reached full speed.
7.1 General Maintenance
Routine maintenance prevents costly shutdown and repairs. Major elements of a controlled maintenance program include:
A. Trained personnel who KNOW the work.
B. Systematic records, which contain at least the following:
(1) Complete nameplate data.
(2) Prints (wiring diagrams, certified outline dimensions). (3) Alignment data (departures from perfect alignment, allowance for temperature). (4) Winding resistance and temperature.
(5) Results of regular inspection, including vibration and bearing temperature data as applicable.
(6) Documentation of any repairs.
(7) Lubrication data (method of application, type of lubricant used, maintenance cycle by location).

7.2 Inspection & Cleaning
Stop the motor before cleaning. Clean the motor, inside and outside, regularly. The frequency depends upon actual conditions existing around the motor. Use the following procedures, as they apply:
A. Wipe any contaminants from external surfaces of the motor.
B. Remove dirt, dust or debris from ventilating air inlets. Use compressed air as necessary.
Never allow dirt to accumulate near air inlets. Never operate motor with the air passages blocked or restricted.
C. Clean motors internally by vacuuming or blowing with clean, dry compressed air. Generally a pressure not exceeding 30 PSI is recommended. When dirt and dust are solidly packed, or windings are coated with oil or greasy grime, disassemble the motor and clean with solvent.
Use only high-flash naphtha, mineral spirits, or Stoddard solvent. Wipe with solventdampened cloth, or use suitable soft bristle brush. DO NOT SOAK. Oven dry (150 - 175° F) solvent-cleaned windings thoroughly before assembly.
D. After cleaning and drying the windings, check the insulation resistance. Refer to Section 3.3.
7.3 Bearings
Proper care will help prolong the life of the motor bearings. Ensure the alignment, belt tension and lubrication is properly maintained.
Motors are supplied with different types of bearings based on application and rating. Bearings supplied are either anti-friction or sleeve type bearings. Bracket construction varies with the type of bearing. Brackets for anti-friction bearings are one piece while those of sleeve bearing have split hubs.
7.4 Bearing Insulation
To prevent bearing damage from circulating current, one or both bearings may be insulated.
Either the shaft or the bearing may be insulated. Note that not all motors are equipped with insulated bearings.
During overhauls, an insulation resistance check may be performed to assure that the insulation has not been weakened or damaged. Resistance can be checked by the use of an ohmmeter.
On sleeve bearing units with both bearings insulated, the bearing grounding strap must be disconnected before testing.
Assure against accidental starting of motor. Disconnect and lock out power before working on equipment. See ‘Safety’ section.

7.5 Bearing Lubrication
A. Relubrication
If motor is being taken out of storage, refer to ‘Storage’ - Section 3.4 for preparation instructions.
For units with Sleeve Bearings:
Select a premium-quality turbine oil which is fully inhibited against rust and oxidation. Refer to Table 5 for recommendations. Oil Pour Point must be below the minimum starting temperature unless sump heaters are used. Oil Viscosity Index must be at least 90.
Add oil to the bearing at the oil fill hole located at the top of each bearing housing. Oil level should be between the ‘Maximum’ and ‘Minimum’ lines located on the housing sight gauge windows. Also fill constant level oilers, if supplied. Refer to motor nameplate for approximate quantity of oil required.
For units with Antifriction Bearings:
Units with grease lubricated bearings are pre-lubricated at the factory and normally do not require initial lubrication. Relubrication interval depends upon speed, type of bearing and service. Refer to Table 3 for suggested relubrication intervals. Note that operating environment and application may dictate more frequent lubrication.
To relubricate bearings, remove grease drain plug. Inspect grease drain and remove any blockage. Add new grease at the grease inlet. New grease must be compatible with grease already in the motor (refer to Tables 3 and 4 for compatible greases and replenishment quantities).
Run motor for 15 to 30 minutes with the grease drain plug removed to allow purging of any excess grease. Shut off unit and replace drain plug. Put motor back into operation.
Greases of different bases (lithium, polyurea, clay, etc.) may not be compatible when mixed.
Mixing such greases can result in reduced lubricant life and premature bearing failure.
Prevent such intermixing by disassembling motor, remove all old grease and repacking with new grease. (Refer to Table 4 for recommended grease).
! CAUTION
Assure against accidental starting of motor. Disconnect and lock out power before working on equipment. See ‘Safety’ section.
! DANGER
Oil ‘Pour Point’ temperature must be below the minimum starting air temperature to ensure adequate bearing lubrication at startup. If this cannot be achieved by oil selection alone then sump heaters should be specified and used to preheat the oil. ! CAUTION

(17) Install drive end bearing ground wire (if applicable) to bearing shell. Make sure the wire does not interfere with the oil ring.
(18) Coat the following part/surfaces with a thin layer of Curil-T:
a. Split surfaces of upper housing (1.1)
b. Back surface of upper housing (1.1) where the machine seal top half (30.1) will mate
c. Split surfaces of lower housing (1.2)
d. Split surfaces of machine seal (30.2)
(19) Very slowly lower the upper part of the housing (1.1) onto the lower half. Ensure that during lowering the already assembled machine-side seal (21.1) locates into the groove provided. Avoid jamming. The upper part must be correctly aligned. Tighten the cover screws (1.3) in a crossways pattern to 30 ft-lbs (41 Nm). (20) Install upper half of machine seal (30.1) onto lower half (30.2). First tighten the splitline screws (30.4) and then the face screws (30.3) to 7 ft-lbs (10 Nm). Re-check clearance between seal and shaft. Clearance must be at least .001 inch at bottom and .003 inch at sides and top.
(21) Coat split lines and flange faces of seal carrier (15.1) with a thin coat of Curil-T.
Prepare the external floating labyrinth seals (20.1) same as was done for the internal ones previously. Place seal carrier halves (15.1) around the assembled floating labyrinth seal (20.1, 20.2) and push the assembly over the shaft and onto the housing.
Tighten seal carrier screws (15.2) to 8 ft-lbs (10.5 Nm). (22) Coat split lines and flange face of bolt-on baffle (25.1) with Curil-T. Position the lower half of the baffle (with drain hole in bottom) such that there is at least .001 inch of clearance to shaft at bottom and .003 inch on each side. Use feeler gauges to install and check clearance. Tighten screws (25.2) to secure lower half. Install upper half on lower half and tighten screws (25.2). Clearance at top of seal to shaft should be .003 inch minimum. Re-check clearance all the way around after all screws are tightened. (23) Install Access Cover to upper half of bearing and to adapter bracket with screws (40.1). (24) Install constant level oilers with sight gauges. The oiler height should be adjusted so that the MAX line on the sight gauge window is above the bottom of motor feet within .06 inch (1.5 mm) of the following values:
Frame Size Height to Max Level Line
5000 9.87 inches (251 mm)
5800 11.25 inches (286 mm)
Note that the opposite drive end oiler should be installed with fan cover sealing plate properly oriented relative to the oiler hose and oiler support bracket. (25) Install bearing temperature probes (if provided) and oil fill and drain pipes. (26) Install fan, fan cover, intake grill, air scoop, conduit box(es) and any other accessory supplied with the motor.

Task 3. Flow Testing
For model calibration and verification purposes, Watearth completed flow tests consistent with the National Fire Protection Association (NFPA) Standard 291, Recommended Practice for Fire Flow Testing and Making of Hydrants. Field testing was required to calibrate the hydraulic system when operational calibration using SCADA is not performed. The field calibration ensured that the model accurately represents an actual system comparing the model results with physical measurements over a range of conditions. With the field calibration data, the model can be used with confidence.

Introduction
The purpose of this document is to provide a flow test plan for the Hemet Water Distribution System Modeling Project which will be applied in Task 4, Model calibration and verification.
Watearth developed a plan for flow testing at various locations within the distribution system.
Watearth suggests six flow test locations, out of a possible ten locations. This plan is consistent with the National Fire Protection Association (NFPA) Standard 291, Recommended Practice for Fire Flow Testing and Making of Hydrants.
Following the flow testing field work, Watearth will perform field-data QA/QC to ensure that the model accurately represents the water system comparing the model results with physical measurements. A summary of the flow testing procedures and location for each flow test are provided in this memo.
Flow Test Setup and Procedure
The information derived from this test will be used to perform the calibration analysis.
Setup at the Pressure Hydrant:
1. Ensure that the two outlets of the hydrant (2.5” and 4.5”) are tight and then remove the
2.5” cap.
2. Slowly open (two-turns) the pressure hydrant to flush until the water is clear. Close the pressure hydrant. Two members of the flow testing team will attach the gauge cap and a 2.5” pressure gauge to the hydrant. Then, the pressure hydrant will be slowly opened to bleed the air from the hydrant body through the valve on the gauge cap. A static pressure reading will be taken when the gauge needle comes to rest.
Setup at the Flowing Hydrant:
1. Ensure that the two outlets of the hydrant (2.5” and 4.5”) are tight and then remove the
2.5” cap.
2. Open the flowing hydrant (two-turns) to clean the hydrant of debris. Close the hydrant to attach the diffuser to the 2.5” outlet.
3. Two members of the flow testing team will communicate that they are opening the flowing hydrant to ensure that the other members of the team at the pressure hydrant are ready to read the pressure gauge.

Hemet Water Distribution System Modeling
Project
2 4. Open flowing hydrant fully (need to have enough discharge at the flowing hydrant) to achieve a drop in pressure at the pressure hydrant of at least 25 percent.
5. Bleed the air from the diffuser gauge and record the pressure at the pitot reading.
6. Personnel at the pressure hydrant will check the pressure gauge and record the residual reading.
7. Close both hydrants slowly, one at a time, and replace the flowing hydrant cap.
Setup the data logger
1. At the pressure hydrant, personnel will attach a data logger at the 2.5” outlet.
2. The data logger will be left for a week recording the pressure.
The Watearth team will document the water flow test results similar to what is shown In Figure 1.

3 Equipment for Flow Test
The equipment needed for field flow testing includes the following:
1. A special hydrant cap tapped with a hole into which is fitted to a 0.25” (6 mm) nipple provided with a “T” connection for a pressure gauge and a petcock at the end for relieving air pressure.
2. A single 100 psi (6.9 bar) or 200 psi (13.8 bar) bourdon pressure gauge with 1 psi (0.07 bar) graduations fixed onto the hydrant cap [if static pressure on the system is greater than 100 psi (6.9 bar), the 200 psi (13.8 bar) gauge will be required].
3. A pitot tube and a 100 psi (6.0 bar) bourdon pressure gauge with 1 psi (0.07 bar) graduations.
4. A diffuser to be attached to the flowing hydrant.
5. Hydrant wrenches to operate the hydrants simultaneously.
6. Playpipes, stream straighteners, or other specially designed flow test outlets with known coefficients of discharge.
Personal Protective Equipment (PPE) needed:
1. Safety glasses,
2. Gloves,
3. Hard hat,
4. Work boots/steel toed boots, and
5. Reflective vest.
Locations for Flow Testing
Watearth has identified ten locations for flow testing; however, due to the small size of the water distribution system, six testing locations will provide enough information on the system pressure. If time permits, all ten locations can be tested for more information. The flow tests will be completed in 6” and 8” water mainlines where the location is far enough from larger water mainline sizes, so a 25 percent pressure drop can be achieved. Since only six will provide sufficient water pressure data, four of the locations will serve as backup if issues arise, such as the following:
1. Potential damage to private property.
2. Private vehicles are close to the test location.
3. High vehicle traffic at the testing time.
4. Damaged or defective hydrants.
5. Not able to reach 20 psi as residual pressure.
The geographic location of each set of hydrants are shown in Table 1 and in Exhibits 1-11

Introduction
This technical memorandum provides a summary of the results of a computerized hydraulic model for the City of Hemet (City) which was calibrated and simulated for Steady States (SS) and Extended Period Simulation (EPS). This document contains the description of the main components such as wells, pumps, storage tanks, transmission and distribution mains, and connections within the city. The base demand in the model was estimated from customer billing data and water production records and was entered in the model as water demand. The model was calibrated and the pressure results between the field-measured and the modelpredicted results are within 5%. The simulated results were reviewed in detail to identify system deficiencies for pressure, velocity, and head loss.
Model Development
Watearth developed and calibrated the hydraulic model to reflect the current water system with existing infrastructure as defined in the City of Hemet Water System Boundaries’ Assessor of Riverside California MapBook, and to reflect current operational control and settings. Some of the key actions that were performed to develop the model include:
1. Check and update model facility attributes.
a) Junctions – ground elevations consistent with existing contour data, demand allocation, diurnal curves with recent billing, and SCADA data. b) Pipelines – Hazen Williams Roughness Coefficient (C-values), diameters, lengths, and current Geographic Information System (GIS).
c) Tanks – base elevations, dimensions, inlet and outlet configuration, and operation.
d) Pumps – pump curves and control settings.
2. Review EPS control settings and tank-level operations based on available SCADA data.
3. Compare model operations against flow field test recordings to determine the operational accuracy of the model and to provide data for model calibration.
4. Perform the model calibration, normal condition scenario, and emergency condition scenario.

2 Water System Distribution and Model
Facility Attributes
This section describes the City’s water distribution system and model facility attributes including model junctions, pipelines, tanks, pumps, wells, and connections.
Water Supply
The water supply for the existing water distribution system is provided by three wells and five connections with the Eastern Municipal Water District (EMWD) as shown in Table 1, and Table 2.
The water distribution system does not contain pressure zones, so one pressure zone was modeled without valves. Water supply capacity is usually given in units of gallons per minute (gpm). Note that wells and connections are connected to the system directly. No one well or connection has a separate water main to a tank site. Furthermore, all wells and connections fill the tanks simultaneously.

Junctions
Elevations were assigned to the nodes from the U.S. Geological Survey (USGS), EROS Data Center as GeoTiff format with a resolution of 1.0 meter (3.28 feet). NAD 1983 State Plane California VI FIPS 0406 feet (ft) was used in the development of the model. The elevation differences range from 1,523.8 ft to 1,740.7 ft where the lowest elevations are in the western portion of the water system and the highest elevations are in the eastern portion of the water system as shown in Exhibit 1.
Pipes
Watearth downloaded the most current GIS file from the City of Hemet Data System in digital form which was reviewed against the Assessor of Riverside California MapBooks in print form.
Before uploading the City GIS pipelines into the model, the pipelines were checked using the GIS Topology tool to capture gaps, duplicate lines, and crossing lines. Then, a check of the connectivity of the model pipelines was performed using InfoWater’s connectivity tools. This includes locating nodes in proximity to pipelines, locating pipe-split candidates, and locating crossing pipes.
The model pipe length corresponds to the actual GIS length calculated using the Calculate Geometry GIS tool which eliminates any erroneous pipe lengths. It is understood that there is no manually entered lengths. There are no pressure reduction valves (PRVs) installed in the water system, according to the City of Hemet Staff.

Task 4 Distribution Model Development
4 The Hazen Williams Roughness Coefficient (C - values) was not included in the City GIS files, so Watearth reviewed the Final Water and Sewer Master Plan, the Final 2020 Urban Water Management Plan, parcel data, and property characteristics to determine the approximate age of the water distribution system. This was done by combining year-built data from Riverside County GIS parcel data and water main shapefile data. To determine the C-values, Watearth used the C- values for discrete pipe diameters (Table 2-1) from Computer Modeling of Water Distribution System, M32, and complement with Evaluation of “C” values to Head Loss and Water Pressure Due to Pipe Aging: Case Study of Uni-Central Sarawak, Asbestos Cement “C” values with Different Ages, Table 4. The most predominant C-values for Asbestos Cement (AC) range from 85-125, 115-130 for PVC, and 130-140 for Steel (SP), as shown in Table 3. The C-value for Steel material does not change too much over the time. As for AC or PVC, it is found in a few locations throughout the system. For example, they may be located after a pump.

For modeling purposes, a diameter greater than 4 inches (in) was used in the model to avoid unexpected results. As shown in Table 4, the diameters in the water system range from 4-in to 24- in where conduits with diameters of 6 in and 8.0 in are most predominant. Furthermore, the most common material in the distribution system is Asbestos Cement (AC). Pipe diameters and materials were identified in the water system as shown in Exhibit 2 and Exhibit 3.

Storages Tanks
There are four tanks in the water distribution system which include two tanks at Park Hill and two tanks at Echo Hills. An altitude valve at Park Hills controls the water level at the tank where the maximum level is set to 35 ft; inflow stops once this level is hit. When the tank is under this level, the altitude valve allows the tank to be filled. The overflow at the tanks is 35.75 ft.

Storages Tanks for Modeling
According to the City of Hemet operations staff, all tanks are being filled simultaneously, and all tanks are being drained simultaneously. Both Park Hills tanks #1 and #2 drain and fill through the same main line to the tank site. Additionally, both Echo Hills tanks #3 and #4 drain and fill through the same main line to the tank site. The water levels at Park Hills tanks are controlled by an altitude valve that operates according to the water demand. The water levels at Echo Hills Tanks control the pump operations (ON and OFF) at the connections and wells through SCADA.
When modeling two tanks at the same site location, which are operated in the same way, it is preferable to model and set one tank instead of two tanks to avoid modeling incongruences.

Task 4 Distribution Model Development
6 Meaning, if Watearth were to model two tanks as it was described, Watearth would expect one tank filling another tank and vice versa. For simplicity, the existing model considers this adjustment as one equivalent capacity tank keeping the water volume constant as if there were two tanks.
1. Park Hills: equivalent diameter, 107.62 ft
2. Echo Hills: equivalent diameter, 113.13 ft
Pumps
A pump is located at each water supply in the system which contains a pump curve, except at Searl and Fruitvale connections which were modeled using design head and design flow. The model pump curve is based on the certified or manufacturer pump curves provided by the City of Hemet as shown in Appendix A. When a pump curve is not available, a design point curve is used. The flow and pressure design values indicated in the Table 6 are the average setting found in the water system according to City of Hemet staff.

Model Demand Development
Water demand assessment was determined from data provided by the City and entered in the model.
Water Demand Calculation
The City provided monthly water billing data and monthly water consumption in cubic feet for the years 2022 and 2023 for about 9,188 customers where the residential customers are the highest water consumer. For 2022 and 2023, it was estimated that the average day demand (ADD) was 2,290 gpm and 2,128 gpm respectively as shown in Table 7.
Additionally, the assessment of daily water production records (2016-2023) from wells and connections- which were provided by the City- indicated that August 16, 2023, was the day of large water production or maximum day demand.
Finally, SCADA records from the City were used to determine the water production for August 16, 2023, which was 3,453 gpm. Additionally, for that day, the maximum day demand (MDD) was 3,082 gpm, and the peak hour demand (PHD) was 4,871 gpm.
14.D
Technical Memorandum
Task 4 Distribution Model Development
8 The industry standards use multipliers to know the variability of the demand. The most common peaking factors are maximum day to average day, which reflects seasonal demands, and peak hour demand to average day demand, which reflects diurnal variations. However, these values are system-specific and depend on the type of water use. Table 8 shows a relationship between the day demands. Water demand for August 16, 2023, is shown in Exhibit 4 where we set a range of consumption to classify the demands in the network.

Customer Demand Allocation
Demand allocation involves calculating the customer demands and then assigning the customer demands to the appropriate junction in the model. The demand for each customer was calculated and allocated using the following process:
1. Billing data records from the city for 2023 were provided to calculate the ADD for each customer which was then scaled up to match the water production for August 16; details are provided in the Water Demand Calculation section under Model Demand Development.
2. Customer address information from the billing data was used to compute the XY coordinate system using a geocode, and then the coordinates were input in GIS as a feature class (shapefile).
3. Pipes, which would not be assigned a demand were flagged. All junctions in the flagged pipe were not assigned a demand. Non-demand junctions include junctions on transmission pipelines, at tanks, at pump stations, and water treatment plants. A demand pipe can have demands assigned, and a non-demand pipe does not have demands assigned.
14.D
Technical Memorandum
Task 4 Distribution Model Development
10 4. Assign each parcel (customer) to a demand pipe by locating the closest model pipe to each parcel and then the closest junction on that pipe as shown in Figure 5. Calculated the total demand at each demand junction as the sum of the demands for the customers assigned to the junction. For instance, in Figure 2 (left side of the network), the red dot (1) corresponds to a residential demand which is assigned to the closest pipe with the shortest distance (d) equal to 2 (P-6). Then, once the pipe was selected, the demand was assigned to the closest junctions (J-1).
5. Verified the allocation for large demands to ensure they were allocated to the more accurate junctions. Large demands are expected in areas with industries or landscape irrigation (parks). This assists in developing a more realistic model.: Customer Demand Allocation in the Model
Source: Closest Junction - Infowater - Innovyze
Diurnal Curve Pattern
In an EPS, a diurnal (daily) pattern is applied to the demands in the model to vary the demands throughout the day. During each timestep of the model run, the demand at each junction is multiplied by the diurnal peaking factor for that timestep.
Water demands for residential areas typically follow a diurnal pattern with demand peaking first in the morning as customers are awake and preparing for work, and again in the evening as customers return home.
2023 SCADA data was provided by City of Hemet staff for many of the facilities: tanks levels, wells, and connections. From Desktop analysis, SCADA data was evaluated to determine the outflow and inflows in the system (water balance). Due to the small size of the system, one diurnal curve is calculated for the entire network.
The diurnal curve for August 16, 2023, was selected because it is when the maximum water production occurred. The diurnal curve represents the hourly water demand within the entire system; it peaks in the morning around 7 a.m., and at night around 7 p.m. Since the water consumption varies during the day, peak factors were developed to represent hourly variation of the average water consumption. Table 9 presents peak values for the maximum water production day for each timestep in the model (1-hour) also shown in Figure 3.

Fire Flow Field Test
Watearth performed a flow test measuring the static pressure and residual pressure at the fire hydrant locations (10). Data loggers were also attached to the 2.5-in hydrant outlets and recorded the pressure for seven consecutive days. The flowing test was performed on November 16, 2023, with representatives from Watearth and the City of Hemet following the flow test plan prepared by Watearth set in Task 2. The pressure data collected in the data loggers were used to calibrate the model by adjusting the pump settings or the Hazen-William Roughness Coefficient. Appendix B contains the Fire Flow plan and Methodology applied.
Design Standards
The following narrative was extracted from the City of Hemet, Standard Specifications for Public Works Construction, Rev. March 2011. The design criteria for the water system establishes the following for demands and mains, pages 28-29. These standards are used to evaluate the hydraulic parameters such as pressure, velocity, and fire flow needs in existing conditions using the EPS model and to determine the deficiencies of the water system.
DEMANDS
Domestic Demands: In residential areas, assume 200 gallons per capita per day and 2.5 persons per unit for an average day.
Maximum day = average day x 2.25.
Peak hour = maximum day x 2.50 – 24
Industrial and commercial demands require a special design.
Fire demands (To be determined by Fire Marshall in accordance with the adopted fire code.) System Demand Criteria: The water Division reserves the right to determine criteria for each water system or sub-system based upon conditions that may exist for that particular location, anticipated level of development, planned use of other criteria.
Specific fire flow requirements will be determined by the Water Division using the recommendation of the Fire Department. Fire Flow for most areas will generally fall within the following limits.
1. Single Family Residence w/sprinklers 500 gpm @ a minimum 20 psi
2. Single Family Residence wo/sprinkler 1,000 gpm @ a minimum 20 psi
3. Multiple Residential & Condominiums 1,500 gpm @ a minimum 20 psi
4. Commercial 1,750-8,000 gpm @ a minimum 20 psi
5. Industrial 1,750-8,000 gpm @ a minimum 20 psi
14.D
Technical Memorandum
Task 4 Distribution Model Development
13 Commercial and industrial development requirements will be analyzed separately based on the specific proposed project.
Pressure:
Minimum residual pressure will be 20 psi at design fire flow plus maximum daily domestic demand.
Minimum residual pressure will be 40 psi at peak hour domestic demand.
Maximum design static pressure will be 100 psi.
When static pressure exceeds 100 psi, reducing valves will be required.
When the area requiring pressure reduction is 25 or more residential lots, a pressure-reducing valve and bypass will be installed in the main.
When the area requiring reduction is less than 25 or more residential lots, individual pressurereducing valves will be installed and maintained by property owners.
MAINS
The minimum size will be 8.0 in, inside diameter.
Locations will be in accordance with the appropriate Standard Drawing.
All lines will be looped; there are to be no dead-end lines.
If approved by the Water Department, temporary dead ends are to be capped and extended beyond the pavement.
Depth of cover (measured from top of finish grade to top of pipe):
Pipes 12 in and smaller require 36 in of cover.
Pipes larger than 12 in require 42 in of cover.
The design will be based on maximum day requirements plus fire flow or peak hour, whichever is greater. For trunk water mains 12 in or larger, design head loss will not exceed 5 feet per 1,000 feet. For distribution mains 8.0 in or smaller, design velocity will not exceed five feet per second (fps)
Thrust blocks will be installed in accordance with appropriate Standard Drawing. If not applicable, a special design is required.
All mains 12 in and larger will have profiles shown on improvement plans accompanied by soil tests and engineering calculations. Smaller mains will be shown where crossing other lines.
Pipe deflections for short radius curves and angle points will normally be accompanied by means of standard fittings, the locations of which will be detailed on the plans.

Calibration
The water supply model uses the operational SCADA data from tanks and pumps located at wells and connections. This data was provided by the City of Hemet for the days November 16 through November 27. After evaluation, the November 18 and 19 were used for calibration analysis since the operational controls are consistent; however, for an EPS analysis only one day is adequate since the controls changed daily. The length of the records and type of data is shown in Figure 4.

Model Controls
As noted in Figure 5, Searl connection’s inflow is represented in the model as a flow of 726 gpm for the entire day. The connection is simulated with a reservoir and a flow control valve (FCV) to secure a constant inflow value. Well 2A was represented in the model by a reservoir, and in contrast to Searl, whose inflows have a constant value, the inflows from Well 2A follow a distribution pattern. From the records, Watearth identified flows of 926 gpm and 1,200 gpm within the duration of a day. This well is controlled by a variable frequency drive (VFD) pump.
Seven Hills connection operates using a VFD pump with inflow of 570 gpm where the pump goes ON and OFF depending on water levels at Echo Hills tank. Similarly, the ON and OFF operations of Well 10A are governed by the water levels at Echo Hills Tank. At certain times during the day, the demand is supplied by inflows from the Echo and Park Tanks which complement the inflows from Searl and Well 2A. The model uses Echo Tank to control Seven Hills connection and Well 10A.
Figure 5: Record of Inflows
Diurnal Curve
The diurnal curve was derived from SCADA on an hourly analysis to compute the water demand and water production based on inflows from wells, connections, and tank level fluctuations. As shown in Figure 6, the water levels in the tanks vary throughout the day indicating that the water consumption follows a diurnal curve shown in Figure 7 which was developed using the inflow information. The diurnal curve shape is similar for both days, starting with an ascending curve during the first nine hours of the day, reaching a maximum and consistent demand around 12:00 p.m. and 8:00 p.m., and experiencing a decrease until 12:00 a.m. The estimated water demand is about 2,102 gpm for the two days being analyzed, November 18, 2023, and November 19, 2023.

Figure 7: Diurnal Curve
The water production calculated was about 2,052 gpm, which is used in the model to mimic the water level in the tanks; and to reproduce the static and residual pressure.
Simulation Assessment
The model was set for SS simulation to validate the assumed pipeline Hazen Williams Roughness Coefficients in the hydraulic model. Ten locations were selected for comparison where static and residual pressure were measured during the fire flow field test, as shown in Exhibit 5 and Appendix B. Thus, the flow calculated at the flow hydrant was entered in the model to determine the residual pressure.
As shown in Table 11, nearly all of the model results are within 10 ft of the head (4.5 psi) of the observed field data as outlined in the criteria contained in the American Water Works Association (AWWA)- Computer Modeling Manual M32. Only the residual test for Location 3 is outside the standard limits. The modeled residual pressure was 28% lower at Location 3 when compared to the observed residual pressure. After a close inspection, this result could be related to one or a combination of the following:

17 1. It is possible that there is a missing existing pipeline connection between the water main in this street and its vicinity, which is not captured in the MapBook.
2. It is possible that there could be a closed valve on one side of the loop. Since the test was done in a main loop, further evaluation could be done in the left and right sections of the loop by closing one valve on one of the sides and taking the static and residual pressure reading in the other side of the loop. This method will help to determine if there is a flow restriction.

The above analysis also agreed with an EPS which involves time steps where the performance of a water distribution system can be assessed. As indicated before, only one day is adequate to assess the model; however, the analysis was extended to two days to determine if the model reflects the actual system’s operating conditions.
Similarly, according to the AWWA, the tank water level fluctuations predicted by the model should be within three to six feet of those recorded in the field. As observed in Figure 8 and Figure 9, the deviations between observed versus predicted levels were not greater than 1.5 ft for each tank. It was not necessary to adjust the diurnal demand pattern as EPS and SS results met the standards described in AWWA – Computer Modeling Manual M32.

Technical Memorandum
Task 4 Distribution Model Development
19 Maximum Day Demand Including Peak Hour (Normal
Operations)
The maximum daily demand for the existing City service area was calculated to be 3,082 gpm.
This maximum day demand represents a peaking factor of 1.45 times the average day demand, 2,128 gpm. During a maximum day demand scenario, the City’s design standards require a minimum pressure of 40 psi to be maintained throughout the water system, and a maximum of 100 psi.
The peak hour demand for the existing City service area was calculated to be 4,871 gpm. This peak hour demand represents a peaking factor of 2.39 times the average day demand. During a peak hour demand scenario, the City’s design standards require a minimum pressure of 40 psi to be maintained throughout the water system.
Furthermore, during normal operations, maximum velocities at the distribution mains should not exceed 5 ft/s.
During a maximum day demand scenario including a peak hour demand, results show that the existing water system could adequately deliver peak hour demands to meet the City’s minimum pressure criterion of 40 psi; however, the maximum pressure exceeds 100 psi in the far west side as illustrated on Exhibit 7 and Exhibit 8.
Maximum Day Demand plus Fire Flow (Emergency
Operations)
InfoWater's "Available Fire Flow Analysis" tool was used to determine the available fire flow at each of the simulated fire flow locations with a minimum residual system pressure of 20 psi within the pressure zone to assess the existing water system under the maximum day demand plus fire flow scenario.
The potable water distribution system of the city includes fire hydrants located around the city to provide water delivery during a fire flow condition. To simulate fire flows in the hydraulic model, fire flow needs were allocated to selected junctions near actual hydrants based on neighboring land use. When there are several land uses at a simulated fire flow junction, the highest fire flow need is assigned. Because the hydraulic model simulates a steady-state scenario, the time component of the fire flow need is not simulated. The hydraulic model only considers the City's existing water system's hydraulic capacity to supply the required fire flow during peak day demand.
The following constraints were considered for evaluation from the Design Standards for maximum Day Demand plus Fire Flow:
1. Single Family Residence without sprinklers, 1,000 gpm @ a minimum 20psi.
2. Commercial and Industrial, 1,750 gpm @ a minimum 20 psi.
As shown in Exhibit 6, the land use data from the City of Hemet was used to assign the fire-flow values to the nodes. For the analysis Watearth assumed that there are not multiple fires, only one hydrant is open at the time, and the duration time is not used for SS simulation.
There were a few areas among residential, commercial, and industrial locations, mostly in the Southeast part of the water system, which did not comply with maintaining a minimum of 20 psi as shown in Exhibit 9 and Appendix C.

20 Results and Conclusions
The existing hydraulic water system was calibrated for SS and EPS and to later be evaluated under Normal Conditions and Emergency Conditions to determine the deficiencies of the water distribution.
Calibration
1. Hazen Williams Roughness Coefficients (C-values): Existing C-values were updated manually using a SS model and mimicking the Static and Residual Pressure values from the fire flow test performed in November 2023. The model results meet AWWA’s standards. Initially, low values were assumed to start off with too much head loss in the water system, then gradually the lowest C-values were increased until the model showed a reasonable alignment with field measurements. The updated C-value locations are shown in Appendix D.
2. Steady State (SS) and Extended Period Simulation (EPS): The SS and EPS models were developed using operational SCADA data from November 2023 which was used to determine the flow settings at the wells (pumps) and connections (pumps), and the water demand diurnal curve. The SS model successfully replicates the static pressure measured in the field at the 10 locations, and the residual pressure modeled replicated nine out of the 10 locations. Finally, the EPS represented the water level fluctuations at Park Hills and Echo Hills tanks. Model results meet AWWA’s standards.
3. Pressure Readings: Regarding pressure readings, the EPS model mimics three representative locations as shown in Appendix E. These locations are in the southern, central, and northern portions of the water system. In communication with City staff, there were no operational changes during the week of the fire field test.
Normal Conditions – Maximum Demand Plus Peak Hour
1. Maximum Velocities: The maximum velocities in the water distribution mains do not exceed 5 fps as shown in Exhibit 7.
2. Maximum Pressure: The modeling results show that static pressures greater than 100 psi are heavily distributed on the west side of the water system, along Lyon Avenue, as shown in Exhibit 8. According to the City of Hemet, Standard Specifications for Public Works Construction, when this occurs, pressure-reducing valves will be required.
3. Minimum Pressure: The minimum static pressures are greater than 40 psi complying with the Design Standards, but it is also noted minimum pressures over 100 psi developed on the left side of Kirby Street where the residences are close to Mary Henley Park.
According to the City of Hemet, Standard Specifications for Public Works Construction, when this occurs, pressure-reducing valves will be required, as shown in Exhibit 9.
Emergency Conditions – Maximum Demand Plus Fire Flow
The analysis indicates that the water system does not comply with minimum flow and pressure (20 psi) requirements at the hydrants which are shown in Exhibit 10. These locations are grouped into four areas as shown below:
1. State Street as shown in Exhibit 11.
2. Rafferty Road as shown in Exhibit 12.
3. East Wesley Place, Olive Tree Lane, and South San Jacinto Street as shown in Exhibit 13.
4. Corner of South Gilbert Street and San Marcos Drive (private connection) as shown in Exhibit 14.
14.D
Technical Memorandum
Task 4 Distribution Model Development
21 As shown in the exhibits, some hydrants do not comply with the minimum flow and minimum pressures along the water mains. On the other hand, some of these areas are related to deadend mains, which are more of a concern than a deficiency because the repercussions are related to stagnation, fire flow reduction, water quality deterioration, and corrosion.
Furthermore, dead ends might have an impact on water pressure, cleansing operations, and water delivery while the main is being repaired or maintained.
Water Quality
Water quality is determined by water chemistry and the physical properties of the distribution system. Nevertheless, this process is time-dependent, making residence time a crucial element impacting water quality. Furthermore, the water age, or the cumulative residence time of water in the system, has come to be recognized as a good surrogate for water quality. According to the City of Hemet, Water and Sewer Master Plan Update, March 30, 2021, there are points where the current system could be affected:
1. Tanks would need to be recoated over four years.
2. The source of water supply is being affected by over-drafting due to a decrease in water table levels and historical agricultural practices.
3. The current system uses four-inch diameter water mains, which reduces flow and has a severe impact on water quality. The short pipelines are incapable of meeting maximum day flow or current fire flow criteria.

Introduction
The purpose of this document is to provide a flow test plan for the Hemet Water Distribution System Modeling Project which will be applied in Task 4, Model calibration and verification.
Watearth developed a plan for flow testing at various locations within the distribution system.
Watearth suggests six flow test locations, out of a possible ten locations. This plan is consistent with the National Fire Protection Association (NFPA) Standard 291, Recommended Practice for Fire Flow Testing and Making of Hydrants.
Following the flow testing field work, Watearth will perform field-data QA/QC to ensure that the model accurately represents the water system comparing the model results with physical measurements. A summary of the flow testing procedures and location for each flow test are provided in this memo.
Flow Test Setup and Procedure
The information derived from this test will be used to perform the calibration analysis.
Setup at the Pressure Hydrant:
1. Ensure that the two outlets of the hydrant (2.5” and 4.5”) are tight and then remove the
2.5” cap.
2. Slowly open (two-turns) the pressure hydrant to flush until the water is clear. Close the pressure hydrant. Two members of the flow testing team will attach the gauge cap and a 2.5” pressure gauge to the hydrant. Then, the pressure hydrant will be slowly opened to bleed the air from the hydrant body through the valve on the gauge cap. A static pressure reading will be taken when the gauge needle comes to rest.
Setup at the Flowing Hydrant:
1. Ensure that the two outlets of the hydrant (2.5” and 4.5”) are tight and then remove the
2.5” cap.
2. Open the flowing hydrant (two-turns) to clean the hydrant of debris. Close the hydrant to attach the diffuser to the 2.5” outlet.
3. Two members of the flow testing team will communicate that they are opening the flowing hydrant to ensure that the other members of the team at the pressure hydrant are ready to read the pressure gauge.

Hemet Water Distribution System Modeling
Project
2 4. Open flowing hydrant fully (need to have enough discharge at the flowing hydrant) to achieve a drop in pressure at the pressure hydrant of at least 25 percent.
5. Bleed the air from the diffuser gauge and record the pressure at the pitot reading.
6. Personnel at the pressure hydrant will check the pressure gauge and record the residual reading.
7. Close both hydrants slowly, one at a time, and replace the flowing hydrant cap.
Setup the data logger
1. At the pressure hydrant, personnel will attach a data logger at the 2.5” outlet.
2. The data logger will be left for a week recording the pressure.
The Watearth team will document the water flow test results similar to what is shown In Figure 1.

3 Equipment for Flow Test
The equipment needed for field flow testing includes the following:
1. A special hydrant cap tapped with a hole into which is fitted to a 0.25” (6 mm) nipple provided with a “T” connection for a pressure gauge and a petcock at the end for relieving air pressure.
2. A single 100 psi (6.9 bar) or 200 psi (13.8 bar) bourdon pressure gauge with 1 psi (0.07 bar) graduations fixed onto the hydrant cap [if static pressure on the system is greater than 100 psi (6.9 bar), the 200 psi (13.8 bar) gauge will be required].
3. A pitot tube and a 100 psi (6.0 bar) bourdon pressure gauge with 1 psi (0.07 bar) graduations.
4. A diffuser to be attached to the flowing hydrant.
5. Hydrant wrenches to operate the hydrants simultaneously.
6. Playpipes, stream straighteners, or other specially designed flow test outlets with known coefficients of discharge.
Personal Protective Equipment (PPE) needed:
1. Safety glasses,
2. Gloves,
3. Hard hat,
4. Work boots/steel toed boots, and
5. Reflective vest.
Locations for Flow Testing
Watearth has identified ten locations for flow testing; however, due to the small size of the water distribution system, six testing locations will provide enough information on the system pressure. If time permits, all ten locations can be tested for more information. The flow tests will be completed in 6” and 8” water mainlines where the location is far enough from larger water mainline sizes, so a 25 percent pressure drop can be achieved. Since only six will provide sufficient water pressure data, four of the locations will serve as backup if issues arise, such as the following:
1. Potential damage to private property.
2. Private vehicles are close to the test location.
3. High vehicle traffic at the testing time.
4. Damaged or defective hydrants.
5. Not able to reach 20 psi as residual pressure.
The geographic location of each set of hydrants are shown in Table 1 and in Exhibits 1-11

Task 5
Task 5. Deficiency Analysis and Correction (Second
Model Run)
Once Watearth identified system deficiencies, the existing distribution model was checked to confirm acceptable performance consistent with AWWA G200-21 Distribution Systems Operation and Management. Watearth explored several feasible alternative solutions for addressing the deficiencies and selected solutions that have minimal secondary effects. The alternative solutions recommended increase pipe diameters, add additional loops, and remove dead-ends within the distribution system as well as identify CIPs appropriate for improving the system.

Introduction
This technical memorandum incorporates several water systems improvements from the City of Hemet – Adopted Capital Improvement, Fiscal Years (FY) 2023-2024, 2027-2028 into the water system model which was previously calibrated based on the fire flow tests performed on October 26, 2023, and evaluated for Normal and Emergency conditions. As indicated in the Task 4 Distributions Model Development memorandum, the model shows that the existing system has deficiencies observed for the maximum and minimum pressure in Normal Operation conditions and Fire Flow conditions as well as residual pressures in Emergency conditions.
Watearth met with the City’s representative to discuss future solutions presented in the Adopted Capital Improvements (FY) 2023-2024, 2027-2028, Capital Improvement Program (CIP). These CIP projects are incorporated into the model as one CIP-Scenario and the results are provided in this memorandum. The simulated results were reviewed in detail to identify remaining system deficiencies for pressure, velocity, and head loss.
Near-Term CIP Project Details
Watearth reviewed the CIP report and included seven projects as indicated in Table 1, Exhibits 1 through 7, and Appendix A. The total cost to complete these projects is estimated to be $16,070,000, based on the CIP project details provided by the City. The projects are intended to improve the current system and are summarized as follows:
1. Upgrade old 4-inch (in) mainlines to 8-in mainlines.
2. Upgrade the Oakland transmission line.
3. Add a new tank to the system and transmission line at Echo Hills.
4. Add in the treated water from a treatment plant into the system.
In the model, the new mainlines are PVC material with a Hazen Williams Roughness Coefficient (C - values) of 150. The new tank is 96 feet (ft) in diameter with a pad elevation of 1,738 ft in the model. When modeling three tanks at the same site location, which are all operated in the same way, it is best practice to model and set as one tank instead of three tanks to avoid modeling inconsistencies. For simplicity, the existing model considers the adjustment as one equivalent tank capacity keeping the water volume constant as if there were three tanks.

CIP Water System Performance
Evaluation
In Task4: Distribution Model Development, hydraulic analyses were performed to identify areas of the existing water system that do not meet the recommended system performance criteria as presented in the Design Standards (Appendix B). In Task 5, Watearth evaluated the CIPs listed in Table 1 and made a distinction in terms of inflows into the system between the design and planning status projects since there could be different effects on the hydraulic results. The modeling analysis represents the day of maximum water production, August 16, 2023.
1. Design CIP Projects: The CIP projects are related to upgrading the size of the existing pipeline by replacing the old water mains and adding a new tank at Echo Hills. The larger size is expected to improve the hydraulic capacity and pressure conditions in the water system. The inflows into the system remained fixed before the Design CIP projects as shown in Table 2.

The Design CIP projects versus Planning CIP projects models were assessed for the demand scenarios discussed in the proceeding section of this memorandum.
Maximum Day Demand Including Peak Hour (Normal
Operations)
The maximum daily demand for the existing City service area is calculated to be 3,082 gpm. This maximum day demand represents a peak factor of 1.45 times the average day demand of 2,128 gpm. During a maximum day demand scenario, the City’s design standards require a minimum pressure of 40 psi to be maintained throughout the water system, and a maximum of 100 psi.
The peak hour demand for the existing City service area was calculated to be 4,871 gpm. This peak hour demand represents a peak factor of 2.39 times the average day demand. During a peak-hour demand scenario, the City’s design standards require a minimum pressure of 40 psi to be maintained throughout the water system. Furthermore, during normal operations, maximum velocities at the distribution mains should not exceed 5 feet per second (fps).
Maximum Day Demand plus Fire Flow (Emergency
Operations)
InfoWater's "Available Fire Flow Analysis" tool was used to determine the available fire flow at each of the simulated fire flow locations with a minimum residual system pressure of 20 psi within the pressure zone to assess the existing water system under the maximum day demand plus fire flow scenario.
The potable water distribution system of the City includes fire hydrants located around the City to provide water delivery during fire flow conditions. To simulate fire flows in the hydraulic model, fire flow needs were allocated to selected junctions near actual hydrants based on neighboring land use. When there are several land uses near a simulated fire flow junction, the highest fire flow need is assigned. Because the hydraulic model simulates a steady-state (SS) scenario, the time component of the fire flow need is not simulated. The hydraulic model only considers the City's existing water system's hydraulic capacity to supply the required fire flow during peak day demand.
The following constraints were considered for evaluation from the Design Standards for maximum day demand plus fire flow:
1. Single Family Residence without sprinklers, 1,000 gpm at a minimum pressure of 20 psi.
2. Commercial and Industrial, 1,750 gpm at a minimum pressure of 20 psi.

Technical Memorandum
Task 5 Deficiency Analysis and Correction
6 Land use data from the City of Hemet was used to assign the fire-flow values to the node locations. For the analysis, Watearth assumed that there are not multiple fires, and therefore, only one hydrant is open at one time. The duration time is not used for steady-state simulation.
Results
Watearth developed the CIP-hydraulic water system to evaluate both the Desing CIP projects and Planning CIP projects under Normal Conditions and Emergency Conditions to determine the deficiencies of the water distribution system.
Design CIP Project Results
Normal Conditions – Maximum Demand Plus Peak Hour:
1. Maximum Velocities: The maximum velocities in the water distribution mains do not exceed 5 fps as shown in Exhibit 8.
2. Maximum Pressure: The modeling results show that static pressures greater than 100 psi are heavily distributed in the following areas: West-Southern side of the water distribution system along Lyon Avenue and Burlington Northern Santa Fe (BNSF) railroad, north of BNSF railroad and the west side of Kirby Street, and north of West Fruitvale Avenue as shown in Exhibit 9. However, Watearth identified this condition as an improvement in comparison to the existing conditions (prior to CIP implementation), where previously, many of the residences located east of Lyon Avenue had pressures over 100 psi.
3. Minimum Pressure: The minimum static pressures are greater than 40 psi, complying with the Design Standards; however, minimum pressures over 100 psi were identified in two locations:
a. On the west side of Kirby Street and BNSF railroad, and b. On the east side of Sanderson Avenue which extends for several blocks.
These locations are shown in Exhibit 10. In comparison with the existing conditions, there is an increase in pressure.
Overall, the water distribution system improved with the installation of CIP projects upgrading of watermain size by maintaining the maximum water pressure under 100 psi.
Compared to the Task 4 Existing Conditions, the areas that showed higher pressures were improved. Additionally, the tanks are storing a higher reserve volume of water which will be used during peak hour demand conditions as shown in Figure 1 below.
During a maximum day demand scenario including a peak hour demand, results show that the existing water distribution system adequately delivers peak hour demands to meet the City’s minimum pressure criterion of 40 psi.

7 Figure 1: Water Level in Tanks – Design CIP Projects
Emergency Conditions – Maximum Demand Plus Fire Flow:
The analysis indicates that the water distribution system does not comply with minimum flow and pressure (20 psi) requirements at the hydrants as shown in Exhibit 11. The locations are grouped into three areas as follows:
1. State Street as shown in Exhibit 12.
2. Julie Way and Rafferty Road as shown in Exhibit 13.
3. East Wesley Place, Olive Tree Lane, and South San Jacinto Street as shown in Exhibit 14.
As shown in the exhibits, hydrants do not comply with the minimum flow and pressure requirements along the water mains. In comparison with the results for the existing systememergency conditions, the increased number of hydrants was minimal and occurred near the same locations.
Planning CIP Project Results
Normal Conditions – Maximum Demand Plus Peak Hour:
1. Maximum Velocities: The maximum velocities in the water distribution mains do not exceed 5 fps in most of the system; however, high velocities of approximately 9.5 fps were identified along Begonia Court, and Zinnia Street as shown in Exhibit 15.
2. Maximum Pressure: The modeling results show that static pressure greater than 100 psi is present in the western portion of the water distribution system, and the pressure is higher in comparison to the CIP Design as shown in Exhibit 16. Watearth attributes this to the inflow from the treatment plant. The inflow is approximately 110 psi operating for the entire day.
3. Minimum Pressure: The minimum static pressures are greater than 40 psi which complies with the Design Standards; however, minimum pressures over 100 psi were identified in the following locations as shown in Exhibit 17:
a. The west side of South Lyon Avenue and south of BNSF railroad,
14.D
Technical Memorandum
Task 5 Deficiency Analysis and Correction
8 b. North Sanderson Avenue south of West Devonshire Avenue and the west side of Kirby Street, and
c. The small neighborhood around El Toro Circle north of Fruitvale Avenue, and the east side of Kirby Street.
Overall, with the implementation of the inflow from the treatment plant into the water distribution system, and operating for the first 4 hours of the day, the maximum pressure exceeded 100 psi in the southwest part of the water distribution system due to high pumping operations (110 psi). The inflows from the plant exceed the water demand and the excess is stored in the tanks, which are not used during the maximum water demand. Furthermore, as shown in Figure 2 below, the tanks reach their maximum level before 6:00 AM and stay at the maximum level for most of the day without flow entering the system.
Figure 2: Water Level in Tanks – Planning CIP Projects
Emergency Conditions – Maximum Demand Plus Fire Flow
The analysis indicates that the water distribution system does not comply with minimum flow and pressure (20 psi) requirements at the hydrants as shown in Exhibit 18. The results are similar to the Design CIP projects - Emergency conditions. These locations are grouped into three areas as shown below:
1. State Street as shown in Exhibit 19.
2. Two locations on Begonia Court as shown in Exhibit 20.
3. East Wesley Place, Olive Tree Lane, and South San Jacinto Street as shown in Exhibit 21.
4. West Westmont Avenue as shown in Exhibit 22.
As shown in the exhibits, hydrants do not comply with the minimum flow and minimum pressures along the water mains.

9 Conclusions and Recommendations
CIP Project Priority
Watearth reviewed the modeling results after implementing the CIP projects and provided a suggested order of priority based on positive impacts in the water distribution system as shown in the list below and Table 5.
1. Priority 1 – Transmission Line Upgrades: The implementation of the water transmission line upgrades will reduce the high-water pressure in the majority of the hydraulic systems.
Once the upgraded transmission lines are put in service downstream of tanks, the static pressure will be reduced within water lines due to the reduction in velocity. This is shown in Exhibit 8 where the velocity in the water mains is less than 5 fps. The water transmission line upgrades are straightforward and cost effective, and will result in systemwide improvements for pressure.
a. CIP 5661: The upgraded transmission line from 12-inch to 16-inch diameter and the 8-inch distribution line alongside a new 18-in water main is a large project that will reduce maximum pressures in the entire system.
b. CIP 5655: The replacement of the existing 12-inch water main with a 24-inch water main from the Echo Hills tank location will help reduce maximum pressures in the water distribution system.
c. CIP 5507: The replacement of the existing 12-inch water main with a 24-inch water main will also help reduce maximum pressures in the water distribution system. This project is smaller in scale and will have less benefit than the other CIP projects but is also less cost.
Priority 1 – Treated Water: The implementation of the treated raw water into the system will benefit the water system by increasing the storage capacity and improving water quality. A plan for more balanced inflow from both the tanks, wells, and connections needs to be further analyzed prior to design. This CIP project needs refinement prior to implementation as they are more costly to install.
d. CIP 5717: The use of treated raw water from the treatment plant is a major project that will improve water quality in the water distribution system. Due to the amount of water involved and the higher cost of this project, more operational analysis is needed for the project before design.
2. Priority 2 – Distribution Pipeline Upgrades: The implementation of distribution pipeline upgrades will help to improve the overall water pressure in the system. Increasing pipeline diameter will reduce resistance in the mainlines while also reducing overall pressure due to pipeline constraints. The distribution line upgrades at specific locations are straightforward and cost effective and will result in systemwide improvements for pressure. These projects will help the city meet water demands of the surrounding areas. a. CIP 5657: The project involves replacement of existing 4-inch water mains with 8- inch mains citywide. The number of upgrades associated with this project will result in systemwide improvements in maximum pressures. b. CIP 5656: The project also involves replacement of existing 4-inch water mains with 8-inch mains, but on a smaller scale with fewer upgrade locations. The upgrades will continue to help reduce maximum pressures within the system.
14.D
Technical Memorandum
Task 5 Deficiency Analysis and Correction
10 c. CIP 5598: Of the distribution line upgrades, this CIP project will have the least overall benefit but still involves replacement of existing 4-inch water mains with 8- inch mains. The maximum pressures will be reduced in the system.
3. Priority 3 – New Tank: The implementation of the new tank at Echo Hills will benefit the water system by increasing the storage capacity. With the addition of the new tank and treated water (CIP 5717), the model results show that there is more water stored than can be used in the water distribution system. A plan for more balanced inflow from both the tanks, wells, and connections needs to be further analyzed before design. This CIP project needs refinement before implementation as it is more costly to install. a. CIP 5655: The addition of the new tank at Echo Hills will ensure both the water for fire protection, and the recommended storage capacity by the Department of Water Resources. This is a higher cost project that requires additional operational analysis, and addressing pressure deficiencies in the system should be a higher priority.

11 CIP Project Environmental Compliance
The CIP projects discussed in this analysis will require environmental compliance which will need to take place prior to CIP project construction.
1. Environmental Determination: Determining how environmental compliance will be handled prior to construction will be necessary. It is possible that CIP projects in this analysis can be considered with a programmatic approach. With this approach, one Environmental Impact Report (EIR) may be sufficient to address the entire water distribution system upgrades. If projects are considered individually, different levels of environmental compliance will be required based on project specifics. The different levels of compliance include but are not limited to notice of exemption (NOE), California Environmental Quality Act (CEQA) Initial Study (IS), or an EIR.
2. Environmental Compliance Timing: Environmental determinations and compliance documents should start well in advance of project construction. If the City is considering a programmatic approach, environmental determination should start soon as CIP projects are scheduled to start as early as 2024. A staggered approach for compliance should be taken if considering each CIP project individually. This process should start soon for higher priority CIP projects. Environmental compliance can be completed concurrently with project design.
CIP 5717 System Optimization
Before incorporating CIP 5717 into the model-CIP Design, Watearth identified improvements with less areas with pressures above 100 psi on the west side of the water distribution system. The reduced pressure is a result of upgrading existing mainlines and adding a tank at Hills Park as discussed in Capital Improvements FY 2023-2024, FY 2027-2028, Capital Improvement Program.
Watearth identified that after incorporating CIP 5717 (inflow of treated water), the maximum water pressure increased in the western portion as well as a large amount of the eastern portion of the water distribution system. To avoid the pressure increase, Watearth recommends the following to be completed as part of Task 6: System Optimization:
1. Inflows from connections: Substitute the inflows from the connections using the raw treated water from Well 15 and Well 16. The inflow pattern will vary throughout the day, maximizing the use during peak hours. The treatment plant will us granulated active carbon (GAC) treatment, and it will run based on the pumps.
2. Use treated water in Peak Hours: Use the treated water to satisfy the water demand only during the peak hours. The pumps from the treatment plant should be on while pumps from the wells and connections are offline. The treatment plant will be used only during the peak hours.
These recommendations as well as additional system refinements will be further analyzed in Task 6: System Optimization.
