RE: Contract No. 2004538
Instrumentation and Control System Replacement at St. Aubin, Seven Mile, and Leib CSO Facilities
Vendor: Burns and McDonnell
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 2004538, “Instrumentation and Control System Replacement at St. Aubin, Seven Mile, and Leib CSO Facilities” with Burns and McDonnell, at a cost not to exceed $7,375,000.00 for a duration of 786 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
GLWA operates nine (9) Combined Sewer Overflow (CSO) facilities. Three of the facilities, St Aubin, Seven Mile, and Leib need control system upgrades. Said facilities utilize Allen-Bradley Programmable Logic Controllers (PLC)-5s series, which are now over 20 years old and are no longer supported, and the manufacturer has discontinued the product. Programmable Logic Controllers are the backbone of the control system and operating obsolete and unsupported products makes operations of these facilities vulnerable.
JUSTIFICATION
The challenge in operating and specifically maintaining end-of-life equipment is when the electronic equipment fails and there are limited resources in obtaining reliable replacement parts. We have been able to reach out to secondhand dealers and third-party sellers to obtain parts, however, it is getting increasingly difficult, expensive, and risky that the secondhand part may fail out of the box.
Utilizing network equipment that does not comply with GLWA SCADA standards increases troubleshooting time and increases vulnerability to cyber security attacks.
