Amended Engineering Feasibility Report
for
Surplus Funds Projects for SRF 3393-01
Executive Summary
This amendment to the Engineering Feasibility Report for SRF 3393-01 is being issued in order
for the City of Pearland to utilize remaining funds and accrued interest from their existing tier II
SRF loan to fund additional infrastructure improvements. The proposed items include the first
phase of a Supervisory Control and Data Acquisition (SCADA) system to include the city's
existing wastewater treatment plants and lift stations. Funding is also proposed for an evaluation
of the Southwest Environmental Center (SWEC) Wastewater Treatment plant service area to
determine the requirements for an expansion to the existing facility.
According to City records there is $1,340,233.11 in funds remaining from the loan, including
accrued interest, through January 9, 2004. The total cost of the items listed above is estimated at
$1.5 million, including contingencies.
General Information
In 1996 the City of Pearland received a State Revolving Fund (SRF) loan from the Texas Water
Development Board (TWDB)in the amount of $8,870,000. The loan contained funding for the
construction of the Southwest Environmental Center (SWEC) wastewater treatment plant along
with associated lift station and sanitary sewer system improvements. An amendment was issued
to the original loan in 2001 allowing for the completion of a waste~vater master plan with surplus
funds remaining at the time.
The wastewater master plan and all construction associated with the original loan are complete at
this time. According to City records there are $1,340,233.11 remaining in surplus funds and
interest as of January 9, 2004.
Description of the Problem and/or Need
SCADA for City Wastewater Treatment Plants& Major Lift Stations
The City of Pearland is currently under contract to Montgomery, Watson, Harza (MWH) to
provide a turn key program of implementing the first phase of a complete SCADA system to
control and monitor the City's water and wastewater system. Phase I, which is the only phase
being proposed for funding at this time, involves installing and configuring of the SCADA
system at the City's four wastewater treatment plants, six major sanitary lift stations, and the
main control center at the Southwest Environmental Center wastewater treatment plant.' The
estimated cost of this project is $1.37 million. See the Attachment 1, which includes a
memorandum from MWH for additional details on the proposed SCADA system.

Funds Projects Loan 3393-01
Evaluation of SWEC Service Area
The portion of the City served by the SWEC WWTP is currently experiencing substantial
growth. The WWTP is operating at approximately 60% of its design capacity at this time. It is
estimated that proposed new connections will increase the flow rate at this treatment facility to
above the 75% and even 90% capacity levels in the near future. In order to budget funds for an
expansion of the facility the City has requested a study to determine when engineering and
construction will need to begin in order for the facility to meet all state and federal capacity
requirements.
Description of the Proposed Project Additions
The only project that will result in the direct installation of improvements is the SCADA system.
All hardware and equipment will be installed inside of existing structures or facilities. These
improvements will include a master control center at the Southwest Environmental Center
Wastewater Treatment Plant and remote access and alarm notification for the following facilities:
Southwest Environmental Wastewater Treatment Plant
Shadow Creek Treatment Plant
Longwood Treatment Plant
Barry Rose Treatment Plant
Walnut Lift Station (LS 1)
Oak Brook Lift Station (LS 38)
Pearland Parkway Lift Station (LS 54)
Green Tee Lift Station (LS 34)
Twin Creek Lift Station (LS 5)
Hatfield Lift Station (LS 13)
The implementation of the SCADA system will allow the city to monitor and operate these
facilities from a central location reducing manpower requirements.
Alternative Considered
Some of the alternatives considered for the control and alarm monitoring of the existing
wastewater facilities within the City of Pearland include the use of auto dialers, radio based
SCADA system, and a phone line based SCADA system.
Auto dialers are currently being used by the City. The auto dialer can call and notify an operator
xvhen problems occur; however, it is not useful to provide remote access and control functions
requested by the City. It also does not send all of its data to a central location for easy
monitoring
A SCADA system based on existing phone lines was considered. This uses existing phone lines
to send control and status data from each facility to a master control station where everything can
be monitored from a central location. This system depends on a third party network of phone
lines that may not be reliable during major storm event.
Page 2 of 4 Amended EFR for Surplus 2/2/2004
Funds Projects Loan 3393-01
The City also considered and selected a radio based SCADA system. This system provides the
same control and monitoring functionality as the phone line based system, but it does not depend
on a third party network to maintain communications. With this system the City installs and
maintains antennas and radio receivers to provide the communication between the remote units
and the central monitoring station.
Proposed Work Plan and Schedule
SCADA for City Waste~vater Treatme~t Pla~tts
The proposed first phase of the SCADA system ~vill be implemented in three sub-phases as
follows:
1. Control Center at SWEC WWTP - The control center shall consist of the SCADA
workstations, report printers, remote access computers, communication hardware,
HMI software licenses, and configuration of all of the above elements.
2. Wastewater Treatment Plants - the initial phase of equipment installation and
configuration for the WWTPs will implement monitoring for the existing plant
processes only. During the initial phase, a more thorough investigation of all plant
process and equipment ~vill be conducted along with discussions with operation staff
to provide a plan for appropriate SCADA control for all WWTPs.
3. Six Critical Primary Lift Station - Provide monitoring and alarm notification for all
six lift stations.
See Attachment 2 for a schedule break down of tasks associated with this Project.
Evaluation of SWEC Service Area
To complete the evaluation of the SWEC service area the Engineer will review wastewater flow
data and connections for past 12 to 18 months. This information will be used to determine
baseline data for flow rates per connection that are currently occurring within the City. This
information will be combined with connection growth projections obtained from current known
developments and estimates of new connections in undeveloped areas. This information will
then be used to determine when the facility will reach its 75% and 90% capacity levels. The
project will be completed ~vithin one month of the Engineer receiving all required information
from the City.
Area Maps
See Attachment 3 for a map of the existing facilities to receive SCADA upgrades
Environmental Issues
It is anticipated that there will be no adverse environmental impacts due to the implementation of
this additional work. The only installation of equipment will be at existing facilities. It is
anticipated that this work will receive a categorical exclusion.

City of Pearland SCADA Master Planning:
Draft TM for Evaluation of Existing Principal
Water and Wastewater Facilities
Date: March 22, 2002
The City of Pearland Public Works Department has contracted Montgomery Watson
Harza to prepare a plan for design and implementation of automation upgrades for the
principal facilities of Wastewater systems.
SUMMARY
The Supervisory Control And Data Acquisition (SCADA) system provides a platform to
monitor and control the Wastewater Systems from a central location. The primary
performance criteria for the SCADA system is that it must be reliable and designed for
continuous operation. The SCADA system will provide the ability for monitoring and
control of remote facilities from one central location.
The recommended SCADA system will consist of three distinct elements. One element
will be the central or master facility. This central control facility will be equipped with
data gathering equipment as well as equipment for display, alarming, and reporting
functions. The second element will be the controllers for all the field facilities. These
controllers will monitor and control the local facility operations. The third element will
be the communication network betWeen these two areas of the SCADA system; the
central control facility and all the remote sites throughout the city.
The central facility will be configured with overviews of the entire Wastewater systems.
The overviews can be readily scanned for verification of overall system performance.
Details for each facility will be made available for closer inspection of a particular
process area or facility. Controls and setpoints for each facility will be available for
applicable facilities. Alarm summaries and reports will be accessed from the central
facility.
A SCADA system which provides local control at the site, while allowing remote
intervention is recommended for the Wastewater Production Divisions. A Local
Controller(s) installed at each facility will be configured to allow monitoring and control.
It will be configured so that selected failures or process anomalies can be handled by the
local controller while als0 notifying the central system of the occurrence. This local
controller will communicate with the central facility to relay information from the local
facility. The controller will also be programmed to allow select changes in operation
configuration from the central control facility.
Reliability of the communications between the central and remote segments described
above is vital. The speed at which these two segments will communicate will also play a
factor in the monitoring and control of the facilities.
CURRENT SYSTEM
The City of Pearland Wastewater Division currently operates three wastewater treatment
plants (WWTPs) and sixty-eight wastewater lift stations located throughout the city. All
of these facilities are operated locally without any remote monitoring or intervention.
The three wastewater plants can operate automatically and unattended. However two
plants, Barry Rose and Longwood WWTPs, both conventional/biological WWTPs, have
very little capability to handling process abnormalities. Both of these plants only have
alarms configured for loss of plant utility power and high level in the event of a blockage
at the inlet bar screens. Manual intervention at the plant is necessary to handle any
unexpected events.
At both the Barry Rose and the Longwood WWTPs, each locally controlled process
operates independently of any others within the plant. If a problem arises in one area of
the plant the subsequent processes will not react accordingly to either accommodate the
problem or shutdown the plant until the problem can be resolved. Neither plant has a
generator installed. Barry Rose WWTP does however have a connection for a portable
generator to supply plant power in the event of utility power failure.
The Southwest Environmental Center (SWEC), a sequenced batch reactor (SBR) plant,
has an existing SCADA and Human Machine Interface (HMI). This plant has limited
HMI set point control capability for the four SBR basins. Additionally the plant was
designed with provisions for the installed HMI system to communicate to other plant
processes. This communication was never completed. SWEC does have additional
alarming capabilities that notify operations personnel when a problem occurs at the plant.
RECOMMENDED FUTURE SYSTEM
SCADA APPROACH
MWH recommends an Open Architecture approach to the new SCADA system. This
approach would incorporate non-proprietary components throughout the system, thus
encouraging a system that is economically efficient. The main advantage in using an
Open Architecture approach is the ease of replacing any component in the system without
affecting the rest of the system. No components in the system will be installed unless
they have the capability of conforming to readily available standards used within the
Process Automation industry. This approach will prevent the end user from being locked
to a particular vendor of the process control hardware or software. This also allows for
more flexibility in choosing process control hardware, HMI software, communication
options, as well as control and monitoring equipment within the facilities.
Another key aspect of a SCADA system should belts ease of expandability. During
System development, care will be taken to conform to established rules and standards.
Using a standardized approach will allow enhancing or expanding the system through use
of the standard formulas for database creation, communication protocol, controller
configuration, and HMI graphic displays.
A goal of the Pearland SCADA system is to provide training to the City of Pearland and
to develop its own technical staff with the ability to work independent after the design,
installation, and implementation of the SCADA system. Training should be to provide
operations, maintenance, and technical personnel to prepare them with the proper
knowledge to operate and maintain the system on a day-to-day basis. Training should
include review of anticipated problems that may occur and show City personnel how to
handle these problems efficiently as possible.
CENTRAL MASTER FACILITY
The central control center for both water production and wastewater facilities should be
located at SWEC. This will allow communication with the remote facilities making use
of the additional phone lines that are available at SWEC and also permit local serial
communication with the plant processes at SWEC.
The control center shall be configured with two high-speed workstations to communicate
with the remote facilities. These workstations should be configured such that one will be
the primary workstation, which will handle all of the communication while the backup
workstation can easily be commissioned to assume control of the communication if the
primary workstation fails. Each workstation should have the ability to monitor and/or
control, as applicable, any of the plant or facilities that are connected to the
communication network. If more workstations are required these will be considered
view/control nodes, and will not have the ability to directly communicate with the remote
facilities, but can communicate with either the primary or backup workstations to receive
information from or send information to the remote facilities.
Alarms for points within the system Can also be generated. The system should be setup
so that on-call personnel can be notified and easily dispatched to the critical area in case
of a failure. These alarms can also be prioritized to minimize notification during non-
standard work hours by non-critical alarms.
The control center HMI system should also be configured so that any data collected will
be trended in graphic displays to show hourly, daily, weekly, and monthly trends. This
data can also be logged historically and used to generate any reports needed, including
any reports for agencies.
The configuration of this system should also be setup so that remote access to the system
can be allowed. With proper security and a remote workstation, operations personnel can
use dial-up access to connect to the SCADA system to monitor and control, if necessary,
any plant facilities that can be monitored or controlled from the central control facility.
This flexibility will allow immediate response to any problems that may arise during non-
standard hours° This feature can also reduce time on-call personnel will spend travelling
to remote plant facilities to resolve critical situations. A system utilizing dial-up remote
access will be provided with adequate security so that only designated personnel will be
granted access to the HMI software.
WASTEWATER TREATMENT PLANTS
The existing HMI system located at SWEC can be enhanced with a more comprehensive
monitoring and control system that will provide better operations for the entire plant.
The local plant lift station, blowers, effluent filters, and UV system can all be added to
the existing HMI. A more thorough alarming scheme can also be implemented to better
enhance the efficiency of the all the plant processes within SWEC.
The Barry Rose and Long~voood WWTPs have a series of independent control systems
within the plant. There is no inter-process communication that will allow a subsequent
process to react in the event of a problem with the previous process. With the installation
of a master controller at the plant, all of the plant processes can be monitored and
controlled as appropriate to better maintain the efficiency of the plant.
Level sensors will be installed in basins, filters, and sumps to provide feedback of current
levels within the plant. Proximity switches will be placed in locations to track status of
clarifier rakes and filter backwashes. Status indications for key pumps, motors, and
valves will be added to provide an accurate account of motor runtime hours and timing of
valve sequence operations. Installation of flow meters will also closely monitor influent
and effluent flow, which are especially important during peak inflow situations.
Industrial monitor displays will be configured and installed to provide local plant
monitoring with SCADA system.
The configuration of these controllers can be designed so that any peak flows or other
process anomalies can accounted for within the controller configuration. This can
minimize or prevent any undesirable plant operation scenarios that could cause improper
regulatory treatment situations.
A preliminary engineering report is recommended for the Barry Rose and Longwood
WWTPs. The plant facilities will be reviewed with engineering, operations, and
maintenance staff to determine which plant processes should be planned for remote
control from the central lOcation or programmed for automated local control. This report
should provide the City with implementation recommendations process control
enhancements of both plants with the SCADA system.
WASTEWATER LIFT STATIONS
There are a series of sixty-eight lift stations currently operated and maintained by the City
of Pearland. The City of Pearland is already in the process of replacing existing level
monitoring components with newer ultrasonic level monitoring devices. In addition to
monitoring wet well levels, the controllers can be setup to monitor pump run status,
4
motor current usage, station intrusion, and station utility power. These controllers can be
configured to start and stop the pumps based on the wet well. Lift stations will be
configured so that they are monitored only~ There will be no remote control of lift
stations.
In the case of the Walnut St. lift station, additional controls could be implemented to
better meter and control flow split between the SWEC and Barry Rose WWTPs.
COMMUNICATIONS
Communications is one of the most important parts of the SCADA system. The integrity
of the communication network and its ability to transfer data, with a high level of
reliability during both normal and emergency situations is an important factor in the
SCADA system design. The communication network needs bandwidth suitable to meet
the Public Works Department requirements to convey data in a timely manner.
Technology advances make it necessary for the communication and computer network
design to incorporate features that support the expansion and reconfiguration needs of the
system without the forfeiture of value.
The option recommended for communication is to use local telephone company dial-up
telephone lines. This option will make use of existing telephone circuits already in place
at most of the major facilities. Using telephone lines will require a number of modems to
be installed at the control center to communicate expeditiously with the number of
facilities connected to the system. There will also be an industrial grade modem at each
remote facility capable of operating in a non-climate controlled facility. Communication
to the SWEC plant will be via serial communication directly within the plant.
The communication recommended for use will utilize a "poll-response" scheme. The
primary workstation will queue up communication for each facility and poll each facility
in a "round-robin" fashion. This method will allow the primary workstation to retrieve
timely information from each remote facility and transfer any control information
necessary each time the host computer communicates with each facility. Communication
failures can be readily determined if a remote facility fails to respond to a poll from the
primary workstation.
RECOMMENDED IMPLEMENTATION SEQUENCE PRIORTY
Based.on field investigations and interviews with various City of Pearland operations and
maintenance personnel, the following list is the implementation sequence priority.
Control Center - The control center should consist of the SCADA workstations,
report printers, remote access computers, communication hardware, HMI
software licenses, and configuration of all of the above listed elements.
2. WWTPs - The initial phase of equipment installation and configuration for the
WWTPs will implement monitoring for existing plant processes only. During the
initial phase, a more thorough investigation of all plant processes and equipment
can be conducted along with discussions with operational staff to provide a plan
for appropriate SCADA control for the WWTPs.
