ITEM SUMMARY:
In September 2013, City Council approved contracts with Clark Dietz and Dynamic Electric for the 2013
Lift Station Automation Improvement Design-Build Project. Said project consisted of furnishing all labor,
materials, and equipment necessary to upgrade the Supervisory Control and Data Acquisition (SCADA)
system (i.e., Programmable Logic Controller (PLC), communication equipment, security equipment, etc.)
at twelve of the City’s thirteen sanitary sewer lift stations. SCADA is a computer-controlled system that
monitors and controls the operations of the lift station’s pumps with the assistance of level transducers
and/or floats to monitor real time sanitary waste flows in and out of the each lift station. SCADA systems
are typically application specific.
In any computerized system, hardware and software upgrades are a required part of routine
maintenance. After a thorough review of our current SCADA system staff have identified several
modifications and maintenance upgrades that are required to keep the current system in good
operational order. A general review of these required upgrades follows:
1. Upgrade Control Software: Each lift station is controlled by a PLC (i.e., a miniature computer).
Each lift station PLC communicates with a master PLC housed at the City’s Water Treatment
Plant that then transmits operational data and alarms to City staff. All PLC’s need software
upgrades. As a part of this upgrade process, the code that operates the units will be reviewed and
revised to more efficiently communicate data. Since the SCADA system communicates using
bandwidth from the City’s internet service provider, this upgrade will have the added benefit of
reducing costs associated with data collection.
2. Establish a Master PLC Backup System: Our current master PLC has no backup system and it
has failed in the past with no warning. When a failure of the master PLC occurs all
communications fail rendering the alarms and monitors inoperable. When it fails, we can no
longer automatically monitor and operate the sanitary collection system lift stations. As part of this
project, a secondary control PLC will be installed at the Water Treatment Plant providing total
system redundancy.
3. Add Reporting Software: Currently the system does not have a reporting function and staff must
manually record data. Part of this project will be the addition of a Microsoft Excel based program,
known as XL Reporter, which will track data in a digital format. This data will be used to improve
lift station efficiency by identifying possible issues before failures occur.

4. Integrate SCADA Systems: Recently the West Chicago/Winfield Regional Wastewater Treatment
Plant completed a significant upgrade of its SCADA system. With upgrades to the City’s lift
Station SCADA system, both systems can be integrated allowing for the sharing of data, thereby
improving operational efficiency.
Currently the City uses Advanced Automation and Controls of McHenry, Illinois to maintain its sanitary
collection and water production SCADA Systems. At staff’s request, Advanced Automation and Controls
furnished a proposal to upgrade the City’s sanitary collection system SCADA for $49,660.00 (see
attached). Advanced Automation and Controls proposal is summarized below:
1. Upgrade Control Software = $25,000
a. Updating Existing Displays = $2,800
2. Establish a Master PLC Backup System = $15,000
3. Add Reporting Software = $4,860
4. Integrate SCADA Systems = $2,000
$60,000.00 has been budgeted in the Sanitary Sewer Fund (05-34-43-4402) for sanitary lift station
upgrades in FY 2019. Staff recommends approval of a Professional Services Agreement with Advanced
Automation and Controls, in the amount of $60,000.00, for all proposed upgrades and any additional
improvements found necessary during the upgrade process. Any other issues found during the upgrades
will be addressed/repaired on a time and materials basis. Staff does anticipate some additional issues
will need to be addressed due to the fact this is a complete system upgrade with outdated software.
Advanced Automationn and Controls is familiar with the City’s current SCADA system and operational
needs, and they have recently successfully completed SCADA system installations associated with the
City’s Booster Station #4 and Sanitary Lift Station #1 Rehabilitation Projects.
As indicated above, the SCADA system is a vital component of the operation of the City’s sanitary sewer
collection system. These proposed upgrades will ensure the system remains operational for the next
several years.
ACTIONS PROPOSED:
Approve Resolution No. 19-R-0049 authorizing the Mayor to execute a Professional Services Agreement
with Advanced Automation and Controls, Inc., for an amount not to exceed $60,000.00, to provide
services related to the 2019 Sanitary Collection System Supervisory Control and Data Acquisition
(SCADA) Upgrade Project.
COMMITTEE RECOMMENDATION:
The Infrastructure Committee voted 6-0 for approval.
