TO: Mayor Robert J. O'Connor
FROM: David E. Schumacher, P.E.; Superintendent of Water Production
DATE: February 14, 2017
SUBJECT:
A Resolution Authorizing the Replacement of Programmable Logic Controllers for Filter Nos. 9 - 12, Claricone 5, and Sample Room 2 for the Water Production Division.
PURPOSE:
To obtain City Council authorization for Tri-R Systems Incorporated (Tri-R), DeKalb, IL, to provide the technical services for replacing and upgrading the programmable logic controllers (PLCs) and related hardware components for Filter Nos. 9 - 12, Claricone 5, and Sample Room 2. In addition, all necessary related programming and system integration with the existing water treatment plant (WTP) SCADA system is to be completed.
BACKGROUND:
In 2016 the same project was completed for Filter Nos. 1 - 8 in order to maintain reliability of the WTP filtration process, a critical step in the overall treatment of surface water from the Fox River. The subject computers/PLCs to be replaced have been constantly operating since they were installed as part of the WTP expansion in 2002 and are nearing obsolescence. With the upgrades, replacement parts will be readily available should future repairs be required.
DISCUSSION:
The labor portion of the project, both installation and programming/integration, is highly technical and rises to the level of professional services. The proposals provided by Tri-R are all inclusive of those professional services as well as providing all needed hardware components at a total cost of $48,050.00. Purchasing delicate and specific electronic components and assuming that they will function together correctly without overall coordination can lead to ongoing deficiencies. Thus, it is believed to be in the City's best interest for one entity to be responsible for not only the successful integration of all the individual components into an updated, functioning system, but to also have the same entity be responsible for providing the exa...
