INTRODUCTION
The purpose of this memorandum is requesting the City Council conduct a public hearing 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system, RS Logix 500, is outdated and the hardware is no longer supported by the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:
