Ray Roberts Water Treatment Plant Regulatory and Performance Upgrades
ATTACHMENT SC.1
SCOPE OF SERVICES AND RESPONSIBILITIES OF CLIENT
PROJECT UNDERSTANDING
The City of Denton (City) has requested that the Ray Roberts Water Treatment Plant (LRRWTP) Regulatory
and Performance Upgrade Processional Services Agreement executed on September 23, 2020, be amended
to include design services associated with the following two items:
• Modification of the backwash supply for the Ray Roberts Water Treatment Plant (WTP) Filter Complex.
• Replacement of additional electric motor operators (EMO) for valves and gates not included in the
original scope of services.
MODIFICATIONS OF BACKWASH SUPPLY
The City of Denton (City) has requested that the Ray Roberts Water Treatment Plant Regulatory and
Performance Upgrade Professional Services Agreement executed on September 23, 2020, be amended to
include design services associated with the modification of the backwash supply for the Ray Roberts WTP
Filter Complex.
The existing filters are classified as self-backwashing style filters. When one filter goes into backwash, the
filtered water exiting the other filters is used to supply the backwash. The existing 30-inch diameter butterfly
valve on the filtered water (filter outlet) line throttles the flow into the filter cell. The City has expressed
concern regarding ability for the flow to be adjusted easily and to ensure that the filters are being adequately
cleaned during a backwash.
Based on input from the City, the proposed backwash supply improvements will generally consist of a ground
storage tank to store backwash at such an elevation as to provide the filters with a wide range of backwash
flows. The major components that will be included in the modifications include:
• Backwash supply ground storage tank,
• Connection to the transfer pump station to fill the backwash supply ground storage tank with chlorine-
free water,
• Flow control valve at the transfer pump station connection to throttle the fill of the backwash supply
ground storage tank,
• Piping from the backwash supply ground storage tank to the filter complex,
• Piping improvements within the filter gallery to accommodate the new backwash supply connection,
• Electrical and instrumentation improvements to support the modifications,
• Programmable logic controller additions and programming modifications to convert to a new
backwash approach.
The Ray Roberts WTP has eight filters, each with dimensions of 16’-0” by 29’-0” resulting in a filter surface
area of 464 square feet (sf). The following backwash protocol is common for many WTPs:
1. Close the settled water valve (filter influent, BFV-F-1x1)
2. The filter will continue treating water as the water level drains.
3. Once the water level in the filter cell is below the top of the backwash troughs, the backwash waste
valve (BFV-F-1x2) will open. Once this valve is open, the troughs will empty, and the settled
water/backwash waste channel will drain.
4. Once the water level in the filter cell is 6 inches above the media (adjustable), the filtered water (filter
effluent, BFV-F-1x3) will close.
5. The air scour valve (BFV-F-1x5) will open, and one of the air scour blowers will begin operations.

6. The air scour process will continue for an amount of time as desired by the City operations team (user
input).
7. Upon the completion of the air scour only timer, the new backwash supply valve (BFV-F-1x6) will open
and the new rate-of-flow control valve at the new backwash supply ground storage tank will begin to
actuate to achieve the desired low backwash rate, as measured by the new master backwash flow
meter located near the new backwash supply ground storage tank. The ramp up to the low-rate
backwash will be 1 minute (adjustable).
8. The low-rate backwash rate is typically 5 gpm/sf (2,320 gpm); however, it will be field adjustable by
the City operations team.
9. The combination air scour/low-flow backwash will continue until the water level within the filter cell
is 6 inches (adjustable) from the bottom of the backwash waste troughs. At this time, the air blower
will shutoff and the air-scour isolation valve (BFV-F-1x5) will close.
10. The low-rate backwash timer will begin with an initial setpoint of 5 minutes (adjustable).
11. The backwash rate will increase from the low rate to the high rate over 1 minute (adjustable). The
high-rate backwash is typically up to 20 gpm/sf (9,280 gpm); however, it will be field adjustable by
the City operations team.
12. The high-rate backwash timer will begin, with an initial setpoint of 10 minutes (adjustable).
13. Once the high-rate backwash timer has been reached, the backwash rate will decrease from the high
rate to low rate over 1 minute (adjustable).
14. The low-rate backwash time will begin, with an initial setpoint of 5 minutes (adjustable). This step
allows the media to re-stratify after the mixing caused by the air scour and high-rate backwash steps.
15. After the final low-rate backwash, the backwash waste valve (BFV-F-1x2) will close, allowing the water
level in the filter cell to increase.
16. As the level approaches the normal operating level, the master rate-of-flow control valve will close.
17. The filter will be allowed to age, with all valves closed, for 5 minutes (adjustable).
18. After the aging process, the settled water valve (filter influent, BFV-F-1x1) will open and the filter-to-
recycle valve (BFV-F-144) will open. The filter-to-recycle process will continue for a period of 10
minutes (adjustable).
19. Upon completion of the of the filter-to-recycle time, the filter-to-recycle valve (BFV-F-1x4) will close
as the filtered water valve (filter effluent, BFV-F-1x3) opens.
Backwash Supply Storage Tank:
Based on the above filter backwash scenario, steps 7 through 15 will impact the size of the backwash supply
storage tank. This scenario requires a backwash supply volume of approximately 144,000 gallons for each
backwash. The current RRWTP backwash sequence uses approximately 250,000 gallons. If the high-rate
backwash was extended from 10 minutes to 22 minutes, the proposed backwash volume would approach
that currently used at the RRWTP. This approach will provide the RRWTP with the flexibility to extend the
backwash, if necessary. Once in operation, if the RRWTP operations team can reduce the backwash volume
used, the excess volume would allow for additional filters to be backwashed in sequence prior to refilling the
tank. Storing four backwashes at the higher volume equates to a volume of 1,000,000 gallons.
The grade near the filters is approximately 598.00±. The top of the filter backwash troughs is approximately
592.10±. This provides approximately six feet of driving head for a backwash; however, the head loss through
the piping, fittings, valves, underdrain, and media would be in excess of this available driving head. Based on
preliminary evaluations, it appears that a ground storage tank may be possible.
A ground storage tank with a diameter of 85 feet and a side water depth of approximately 24 feet will provide
a volume of 1,020,000 gallons. The proposed location for this tank will be adjacent to the transfer pump
station. A second tank could be designed and constructed in this space beyond a RRWTP capacity of 50 MGD.

SC-3
DTN20672 Amendment No. 1
Ray Roberts Water Treatment Plant Regulatory and Performance Upgrades
A master rate-of-flow valve and flow meter will be provided near the backwash supply storage tank to throttle
the backwash flow to the filters.
Transfer Pump Station:
Each of the three transfer pump station pumps has a rated head of approximately 34.25 feet. The clearwell
finished floor elevation is 596.00± and the overflow elevation is 628.00±. The inlet piping of the clearwell has
a riser pipe with an elevation of 612.00±. The backwash supply storage tank geometry will be critical in
balancing the flow split from the transfer pump station to the backwash supply storage tank and clearwell.
Modifying the transfer pump station controls are not anticipated to achieve the above backwash protocol.
Filter Piping Modifications:
A pipe from the backwash supply tank will be provided to accommodate the high-rate backwash. This pipe
will have provisions to connect to future filter galleries as the LRRWTP expands. This backwash supply pipe
will split to accommodate the two existing filter galleries. It is anticipated that this pipe will have a diameter
of 24 to 30 inches. Due to space constraints within the filter pipe gallery, the backwash supply headers will
need to stay outside. Backwash supply drops for each filter will drop below grade and penetrate the existing
exterior wall of the filter pipe gallery so that the backwash supply line will be below the access platforms. The
individual filter backwash supply isolation valve will be equipped with an open/close electric motor operator
and will be located exterior to the pipe gallery. The existing 30-inch diameter filtered water piping within the
filter pipe gallery between the existing filtered water (effluent) butterfly valve (BFV-F-1x3) and the fittings at
the filter cell wall will require modification. It should be noted that the space in this area is extremely tight.
Besides the eight penetrations through the exterior wall, additional wall penetrations may be required for
Filter No. 4 and 8 to support piping installation and connections.
REPLACEMENT OF ADDITIONAL ELECTRIC MOTOR OPERATORS
The City of Denton (City) has requested that the Ray Roberts Water Treatment Plant Regulatory and
Performance Upgrades Professional Services Agreement executed on September 23, 2020, be amended to
include design services associated with the replacement of additional electric motor operators for valves and
gates not included in the original scope.
The existing electric motor operators utilize a serial RS-485 communication protocol, which has been
problematic for the Ray Roberts Water Treatment Plant (WTP). The new operators will use individual
input/output (discrete and analog) conductors to remedy those challenges and provide more stable and
efficient communication.
The valves, sluice gates, and slide gates associated with these additional EMO replacements will not be
replaced and will remain in service.
The PLCs identified within this Amendment will accept the following input/output (I/O) points from each
motor operator being replaced:
• Discrete Input
o In Remote
o Fully Open
o Fully Closed
• Discrete Output
o Open Command
o Close Command
• Analog Input (Modulating Duty Operators Only)
o Valve Position Feedback

• Analog Output (Modulating Duty Operators Only)
o Valve Position Setpoint
The modifications for the PLCs listed below are limited to adding I/O points to support the EMO replacements;
however, no additional programming or transfer of process control and monitoring is included with these
services. The majority of the plant processes’ current monitoring and control strategy are executed by the
Think-and-Do server, and the City is currently working toward replacing the Think-and-Do server with a
Modicon M580 data aggregator. The current programming associated with monitoring and controlling the
processes and valves will remain in the current system and configuration and will not be transferred to the
new PLCs identified in this Amendment. The modifications to or replacements of the PLCs identified below
are limited to gathering the necessary I/O associated with the electric motor operators identified in this
Amendment.
Ray Roberts Water Treatment Plant Electric Motor Operators:
The additional electric motor operators to be replaced at the Ray Roberts WTP are summarized in Table 1.
Based on input from the City, the valves and slide gates attached to the electric motor operators listed below
will remain in place. No valves or gates will be replaced as part of the operator replacement.

The switch from serial RS-485 communication to individual I/O (discrete and analog) conductors for each
operator results in additional conduit and conductors. In addition, several programmable logic controllers
(PLCs) will require modifications to support the additional I/O conductors.
This Amendment will also include the following modifications to the Ray Roberts WTP PLCs listed below:
• PLC-06:
o PLC-06 is located within the Operations/Administration Building Electrical Room. The original
Project included the addition of a small number of I/O points but did not require the
replacement of this PLC.
o Due to the increase in the I/O points, this PLC will require replacement due to the lack of
available input/output points. Space within the Operations/Administration Building Electrical
Room will not allow the installation of a second PLC. The original PLC and the associated
cabinet will be replaced with a Modicon M340 PLC. The field wiring between the PLC cabinet
and the existing field devices will remain and not be replaced. The construction sequencing
of this work may request that the Ray Roberts WTP be offline for approximately two (2)
weeks.
o The following electric motor operators will be assigned to this PLC:
▪ MV-FS-1
▪ TV-FS-1
▪ MV-FS-2
▪ TV-FS-2
▪ BFV-WR-292
• PLC-10:
o As part of the original Agreement, PLC-10 was added at the Biologically Active Filters to
support the improvements designed at Filter Nos. 5 through 8.
o Additional design will be required to support this Amendment.
o The following electric motor operators will be assigned to this PLC:
▪ SLG-IOC-1
▪ SLG-IOC-2
▪ SLG-IOC-3
▪ SLG-IOC-4
• PLC-13:
o As part of the original Agreement, PLC-13 was added to the Transfer Pump Station Electrical
Building to support the improvements designed at the Water Reclamation Basin.
o Additional design will be required to support this Amendment.
o The following electric motor operators will be assigned to this PLC:
▪ WG-TP-1
▪ PV-TP-249
• PLC-14:
o An additional PLC will be required due to the number of I/O points added with the electric
motor operators listed below. The current Pre-ozone Contactor operators are connected to
PLC-02 (Ozone Building) via serial RS-485. Due to the length of the duct bank, conduit, and
conductors required with this operator placement, a new Modicon M340 PLC is proposed.
o PLC-14 will be a new PLC as part of this Amendment and located at the Pre-Ozone Contactor.
o The following electric motor operators will be assigned to this PLC:

Electronic Record and Signature Disclosure
ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, City of Denton (we, us or Company) may be required by law to provide to
you certain written notices or disclosures. Described below are the terms and conditions for
providing to you such notices and disclosures electronically through your DocuSign, Inc.
(DocuSign) Express user account. Please read the information below carefully and thoroughly,
and if you can access this information electronically to your satisfaction and agree to these terms
and conditions, please confirm your agreement by clicking the 'I agree' button at the bottom of
this document.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. For such copies, as long as you are an authorized user of the
DocuSign system you will have the ability to download and print any documents we send to you
through your DocuSign user account for a limited period of time (usually 30 days) after such
documents are first sent to you. After such time, if you wish for us to send you paper copies of
any such documents from our office to you, you will be charged a $0.00 per-page fee. You may
request delivery of such paper copies from us by following the procedure described below.
Withdrawing your consent
If you decide to receive notices and disclosures from us electronically, you may at any time
change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your
DocuSign account. This will indicate to us that you have withdrawn your consent to receive
required notices and disclosures electronically from us and you will no longer be able to use your
DocuSign Express user account to receive required notices and consents electronically from us
or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through your DocuSign user account all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or
made available to you during the course of our relationship with you. To reduce the chance of
you inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.
