To whom it may concern,
Attached is an application for a Non -Conjunctive Reclaimed Water Generation, Distribution,
and Utilization
System Permit modification. WithersRavenel is submitting the application on behalf of the
Town of Mount
Olive. The Mount Olive Wastewater Treatment Plant (WWTP) reclaimed water land application
system is
operated under Non -Discharge Permit number WQ0029169.
Modifications to the Mount Olive, NC WWTP non -discharge permit were conditionally
approved by
NCDEQ as part of another permit modification request. Approval of the request was received
from NCDEQ
on October 12, 2020. The previously permitted project included upgrades to the WWTP's
existing reclaimed
water land application fields and irrigation system. Specifically, the project sought to replace
the previous
drip irrigation system and hybrid sycamore tree crop with a spray irrigation system and
Bermuda grass crop
due to failure of the drip irrigation system. Upgrades to the irrigation pump station and
associated controls
equipment were also approved. These modifications are currently in the final phase of
construction. No
increase in permitted monthly average flow or maximum instantaneous application rate was
requested in
the previous 2020 permit modification.
The former permit modification included application of reclaimed water to areas that have
since been
rlccmcrl —... if.hlc fnr fhc ­A...hi—mi44cr1 onnlirofinn rofc of Al in/v Thic �unc

determined via
updated soils evaluations which were performed in 2022, and the project design has been
modified
accordingly to ensure no over -application to those areas. The updated soils evaluations
determined new
boundaries of areas suitable for 61 in/yr and determined appropriate annual application rates
forfour(4)
field areas deemed unsuitable for 61 in/yr.
This permit modification request seeks to approve changes to the design based on the
updated soils
evaluation. These changes include irrigation of four areas which were previously permitted for
61 in/yr but
have now been found to require reduced application rates. These areas are in Fields 3, 4, 7,
and 9 and are
designated 3R, 4R, etc. The design has been updated to utilize spray guns with reduced flow
rates in those
areas where needed to match the application rates recommended by the soil scientist.
Sprinkler spray paths
have also been updated to ensure spray guns designed to apply 61 in/yr spray only within
suitable areas.
Lastly, this modification seeks to approve an increase in the permitted monthly average land -
applied flow
from 560,893 gpd to 623,216 gpd. The newly requested average flow is based on the updated
field areas
and annual application rates, as shown in the attached supporting water model results report
and water
balance calculations. No increase in the previously approved maximum instantaneous
application rate of 0.4
in/hr is requested. Approval of reduced maximum instantaneous rates is requested for the four
reduced
areas; the updated, reduced instantaneous rates for those areas can be found in the attached
supporting
documentation. Please also noted that there are no requested changes to the modifications
for the irrigation
pump station and transfer pump station that were already approved under the last Major
Modification in
2020.
The approximate construction timeline for these modifications will be from November 2022 to
March 2023
and will occur concurrently to completion of construction for the previously approved project.

1.0 -INTRODUCTION
The Town of Mount Olive Wastewater Treatment Plant (WWTP) previously operated a drip
irrigation system with a cover crop of sycamore trees to land-apply reclaimed water. The
Town is currently in the process of converting their existing drip irrigation fields to a spray
irrigation system with a grass cover crop which was approved under a previous permit
modification application. Construction of the spray irrigation system is nearing completion.
®
To aid in the design of the system, WaterGEMS water modelling software by Bentley was
utilized to model the sprayfield system design and verify the hydraulics. A re-evaluation of
the irrigation field soils was performed following clearing of the former tree crop. The new
soils evaluation resulted in changes to the design and operation of the spray irrigation system
and the WaterGEMS model has been updated accordingly. The updated water model results
confirm that the sprayfield design and pumps will meet the proposed permitted application
demands, which is confirmed by water balance calculations. This engineering report describes
the sprayfield design constraints, model inputs, and model results for the new sprayfields.
2.0 - DESIGN CONSTRAINTS AND MODEL INPUTS
2.1.1 - Permitted Limits
The existing fields are permitted under a non-conjunctive, reclaimed water permit
(WQ0029169). The following are existing limits on the permit:
560,893 gpd averaged monthly
0.4 in/hr maximum instantaneous application rate
61 inches annual application

This permit application is requesting an increase in the average daily flow (averaged monthly)
applied to the fields from the above value to 623,216 gpd. As discussed later in the report,
this new average daily flow quantity is based on the soil scientist approved annual application
rates and field areas; it also accounts for disposal of precipitation entering the storage
lagoon. No increase in maximum instantaneous application rate or annual application rate is
requested. Approval of reduced annual application rates for areas deemed unsuitable for 61
inches per year (in/yr) is also being requested.
2.1.2 - Sprayfield Operation
Each field will be operated separately. Prior to replacement of the drip irrigation system, the
fields were operated for approximately 12 hours per day and the design goal was to maintain
a similar schedule. An operation schedule of 4 days per week was chosen such that three (3)
fields are irrigated per day. In order to minimize pump sizing and electrical requirements, one
field is to be irrigated at a time. One field will be irrigated before moving on to the next field.
Since the fields have varying numbers of spray guns and elevations, the irrigation time for
each field will vary slightly. The target runtime per field is four (4) hours. However, the design
runtimes have increased due to the removal of spray guns following the updated soils
evaluation. The control system will continually monitor the flow rate to the field being
sprayed using a magnetic flow meter. Once the total volume to be applied to that field has
been reached, the system will switch to the next field.
Four field areas were determined by the soil scientist to be unsuitable for application of 61
in/yr. These areas are part of Fields 3, 4, 7, and 9 and are referred to as Fields 3R, 4R, 7R and
9R. Each of the areas will be sprayed at the same time as the associated field, but lower flow
spray guns and/or a reduced number of guns will be used to adhere to the reduced suitable
application rates. Two spray guns in Field 4 and one spray gun in Field 10 had to be made
Town of Mount OliveSprayfield Model Analysis
WWTP ImprovementsPage 1

inactive due to them being outside of the suitable irrigation areas. Valves associated with the
lines feeding these guns will be kept closed.
As shown in the attached Water Balance Report, Field 9R cannot be irrigated for the entire
year at the full model-predicted flow rate. It is recommended that Field 9R only be irrigated
during the months of May, June, July, and August each year. The valves associated with all
spray guns that apply water to Field 9R will be closed during the periods of the year where
water is not being applied there, but water will continue to be applied to Field 9. The model
indicates that a small increase in the instantaneous sprayed flow to Field 9 will occur when
Field 9R is not being sprayed. However, this difference in flow will be automatically
accounted for by the SCADA system, which tracks flow to all fields via a magnetic flow
meter. Field 9 will therefore have the same average daily flow throughout the year,
regardless of whether Field 9R is being sprayed or not. There will be a slight decrease in
spray time for Field 9 when Field 9R is offline, but the difference is negligible and therefore
is not reported here. The values reported below are for when Field 9R is online.
2.1.3 - Equipment
2.1.3.1 Pipes
Underground piping in the fields is PVC SDR 21. Piping at the irrigation pump station
and valve stations is ductile iron. The risers supporting the spray guns will be Schedule
40 galvanized pipe in order to avoid UV damage of the pipes. The spray gun risers
were modeled with the fittings shown on Sheet 8 of the Contract I drawings.
2.1.3.2 Spray Guns, Risers, and Spray Gun/Emitter Coefficient
Two spray guns were selected for areas suitable for 61 in/yr, one for full circle
application and one for half circle application. The half circle gun was chosen so that
it applies 50% of the full circle flow since it will cycle over the same area twice as much.
For the reduced application rate areas, a lower flow spray gun was selected. In one
case, a 61 in/yr full circle gun was used in a reduced area, as discussed in the Model
Results section. The specified spray guns selected are listed below, along with the label
used to identify each one in the plans:

SG1: Nelson Big Gun 75 Taper Ring, 0.40-in (reduced areas)
SG2: Nelson Big Gun 100Taper Bore, 0.55-in (half circle)
SG3: Nelson Big Gun 100 Ring Nozzle, 0.89-in (full circle)

Cutsheets for the selected spray guns are provided in Appendix B.

As the pressure at each gun increases, the application rate and wetted diameter
increases. This relationship was provided by the manufacturer and modeled with
WaterGEMS using a simple power equation. The equation used is:
=
Where Q is the flow rate in gpm, k is the emitter coefficient, P is the pressure in psi, and
n is a fitting parameter. WaterGEMS assumes n=1/2 and k is unique to the emitter/gun.
The emitter coefficient was determined by fitting the manufacturers data to the above
equation to determine k for each gun. A k value was developed each of the three guns
and assigned accordingly to junctions representing spray guns in the model. Tables 1,
2, and 3 show the pressure versus flow for the guns used along with their calculated k
value.

2.1.4 -Design Goals and Constraints
Each field will be operated independent of the other fields, except for the four reduced
application rate areas, as discussed in the Model Results section. Each field was
modeled as a separate scenario in WaterGEMS. Pipe sizes were adjusted to achieve a
minimum velocity of 2.5 ft/s to ensure scouring and below 8 ft/s to avoid excessive
velocities and headloss. The pumps were selected to provide a minimum pressure of 50
psi at the spray guns for all fields. Field 4 required the highest total dynamic head (TDH)
from the pumps of all the fields; the pump was selected to ensure it could supply the
required flow and head to this field without hydraulically overloading the other fields.
The Water Balance Calculation Report and adjunct soil scientist evaluations, which are
also attached to this submittal package, provide the max. allowable annual and
instantaneous application rates for all the fields, to which model results will be
compared to ensure no exceedances in modeled flows occur.
2.1.5 - Pump Selection
The installed pumps for the irrigation system are American Marsh 480 Series Vertical
Turbine Model 12LCR with a design point of 1,776 gpm at 191 ft TDH for two pumps
in parallel. These pumps were used within the water model to ensure that they would
meet or slightly exceed the other operating points (shown in Table 4), and that they
would fit within the existing irrigation wet well. The station will operate as two (2) duty
pumps and (1) standby pump. The pump curve is provided in Appendix A along with
the matching pump curve used in the model.
2.2 - MODEL RESULTS
The WaterGEMS model was ran at steady state for each field using the pump selection
specified in Section 2.1.5. The results showing spray gun pressures, pipe velocities, and
pump conditions are listed below in Tables 4, 5, and 6.

The previously approved flow rate of 560,893 gpd (averaged monthly) was based on
design limitations of the former drip irrigation system design. Table 7 shows suitable
annual application rate for each field as provided in the attached soil scientist
evaluations. The requested increase in allowable average daily flow is calculated from
the field areas and suitable annual application rates.

Given the steady state demands for each field and the permitted application rates, the
runtime for each field was calculated to ensure the runtimes complied with the
operation schedule and were able to apply the requested flow of 628,548 gpd,
averaged monthly. Table 8 shows the runtime required for each field to meet the
weekly application volume, which is calculated based on the average daily flow over
seven days. The instantaneous application rate (in/hr) and total annual depth were also
calculated to show that they comply with the requested permit limits.

*Note that required run times to meet annual application rates for all the reduced areas (3R, 4R, etc.) are
higher than the required run time for each of the associated fields (3, 4, etc.). The reduced areas will be
sprayed concurrently with the associated fields, so the actual application times will be lower than those
shown in the table for those areas. This will help ensure that the reduced application rate fields are not
Town of Mount OliveSprayfield Model Analysis
WWTP ImprovementsPage 7

over-sprayed.The spray quantities used in the water balance for the reduced rate fields match the lower
times for the associated fields, I.E. the spray time used for Field 4R is 4.3, not 5.6, as discussed below.
Because the reduced application rate areas (Fields 3R, 4R, 7R, and 9R) will be sprayed concurrently
with each of the associated fields (Fields 3, 4, 7, and 9), the total amount that is able to be applied
must be reduced from 628,548 gpd to 623,216 gpd, as shown in Table 9.

2.2.3 - Calculated Application Times and Rate for Water Balance
As part of the design, a water balance was performed to ensure the system could apply
both the reclaim water and additional water resulting from precipitation. The full water
balance report is a separate document with the application package. The result of the
water balance confirms that 623,216 gpd can be effectively applied to the irrigation
th
fields, accounting for the amount of storage in the existing lagoon and 80percentile
precipitation. This verifies that the model results and calculated runtimes reported

There are many things to consider when a motor is powered using a

the motor windings very often see a large differential voltage, either from
