INTRODUCTION
The purpose of this memorandum is to establish the date for the public hearing and to
authorize the public bidding procedure for the Water Treatment Plant SCADA System
Upgrade Project.
BACKGROUND
The Dubuque Water Works, known as the Eagle Point Water Treatment Plant (WTP), treats
and distributes on average 7 million gallons per day (MGD) through a distribution system
comprised of over 330 miles of water main via a combined fourteen (14) storage tank and
pump station sites. The WTP operators control and monitor the treatment and distribution of
drinking water from the treatment plant via a SCADA or Supervisory Control and Data
Acquisition system.
The SCADA system is linked to each of the remote distribution system sites via radio
communications from the WTP. Data collected from each of the remote sites is transmitted
back to the WTP and the operators at the plant routinely interact with the SCADA system to
make decisions on water production, storage, and overall supply to the distribution system
including during emergency situations such as main breaks or fire events. The SCADA
system is currently the only method of data collection used for informing the operating staff
on what changes are occurring in the water supply and distribution system and how the
operators need to respond.
Beyond immediate operations, the SCADA system eliminates the need for manned
operations at each remote site. It provides constant monitoring of tank and pump station
operations. SCADA also provides a level of security with immediate reports of any security
breaches or abnormal operating conditions. Having a reliable SCADA system also reduces
the number of patrols and manned visits to each of the remote sites reducing overall costs.
The current SCADA system has been in place since 1993 and the programming and
operating system, RSLogix 500, is outdated and the hardware is no longer supported by the
manufacture/vendor and will need to be replaced for continued WTP and remote
operations. In addition, the existing hardware has reached its capacity for installing new
infrastructure controls and devices required to communicate with tanks, towers, and pump
stations.
DISCUSSION
The Water Treatment Plant SCADA System Upgrade project provides for the replacement of
the existing Supervisory Control and Data Acquisition (SCADA) hardware and software at the
Eagle Point Water Treatment Plant and remote sites including the wells, pump stations, tanks,
and towers.
The programmable logic controllers (PLCs) and other major components of the existing
SCADA system have become obsolete. Additionally, very little of the softening, filtering, and
sludge treatment equipment at the WTP is currently monitored by SCADA. It is desirable to
install an Ethernet network and add additional control panels in select locations within the
WTP to connect important instruments and include provisions for future additions.
The existing SCADA software at the WTP is not compatible with the software packages
currently in use at the W&RRC. To improve efficiencies associated with problem solving or
cross training of staff, it would be desirable for the replacement SCADA system WTP
software to be compatible with, and possibly integrated into, the W&RRC SCADA system.
Replacing the SCADA system at the WTP would not only replace outdated and obsolete
equipment, hardware and software, it would also provide an opportunity to make operational
efficiency improvements.
While the current SCADA system is capable of collecting and reporting chlorine, pH,
turbidity, flow, and pressure measurements at the WTP, with chlorine, tank elevations,
pressures and intrusion alarms reporting back from the remote sites, there are additional
monitoring possibilities. With added SCADA controls, new analyzers could be introduced to
provide further on-line measurements including flow and pressure readings at the pressure
reducing vaults, distribution system flow measurement reporting as part of a District
Metered Zone program to reduce and detect leaks and main breaks, and research
continues in the water industry, the possibility of on-line monitoring for the detection of
contaminants in the distribution system.
An additional benefit of a replacement SCADA system in coordination with the change from
radio communications to fiber optic communication (the fiber optic project will be under a
separate RFP) includes the option to enhance security at the remote sites. Such security
measures would include the ability to add video cameras, motion detectors, contact
switches, keypad entry devices and card readers, which can be interfaced directly to the
SCADA system and provide live information back to the operators.
The city selected Strand Associates through the public RFP process to complete the design,
specifications and assist the city through the SRF loan application procedure. The Strand
design team have completed the design and bidding documents, and the city has received
an approved preliminary engineering report letter dated April 29, 2024, from the Iowa DNR,
therefore the project is ready for public bidding. The goal is the complete installation of the
engineer designed SCADA system and initiate the public bidding process to meet the
following deadlines:
