Title
Supervisory Control and Data Acquisition (SCADA) System Upgrade
History
The Supervisory Control and Data Acquisition (SCADA) system has performed all functions relative to the water system and twenty-four (24) hour monitoring of the sanitary system since 1985. With technological changes over the years, the system has evolved utilizing modern computers and software. The system was last upgraded in 2005 with the addition of new desktop computers and a software upgrade. No additional improvements have been made since. The current system, according to industry standard, is considered beyond its serviceable life.
In order to ensure the reliability and security of the SCADA system, an assessment was completed in December 2011 by the Utility Division’s SCADA consultant and integrator, B&W Control Systems, LLC of Crystal Lake, Illinois. The assessment results indicated that:
1. The computers that operate the system are failing and are in need of immediate replacement.
2. Software upgrades are needed to improve operations and minimize the vulnerability to viruses and cyber attacks.
3. Environmental improvements to protect the computer equipment from heat, dust and humidity are needed to avoid premature equipment failures.
Due to the complexity of our SCADA system and the current role B&W plays for the Village as our integrator, a proposal for equipment and software upgrades was requested from B&W Control Systems, LLC of Crystal Lake, Illinois. They were the previously selected vendor from 2005, completed the assessment in 2011 and have an overall understanding of the project with the ability to provide continued support. Upon review with the MIS Department, it was determined the computer equipment could be purchased independently at a lower cost. A revised proposal was submitted including only installation, software upgrades and ongoing support in the amount of $38,240.00.
The MIS Department, after consultation with B&W, has obtained proposals from...
