Subject: Approval of Process Control Services as the Single Source Vendor for instrumentation
troubleshooting and repair of the Programmable Logic Controller (PLC) and Supervisory Control and
Data Acquisition (SCADA) systems
Background Summary:
The City of Ocoee's Utilities Department operates two (2) water treatment plants, two (2) reclaimed
water pumping facilities, sixty-six (66) wastewater lift stations, and one (1) wastewater treatment plant.
The advanced operations at the plants, pumping facilities and lift stations are managed by the utilization
of two computer systems. The PLC system directly administers the plant's processes while the SCADA
system allows unmanned automated operation of the facilities as well as collection and storage of
information and emergency alarm condition "call outs" to stand-by personnel. The effect of the PLC
being inoperable is immediate and can be significant in terms of treatment. A SCADA failure may not
affect treatment for an extended interval, but will lead to treatment issues and also disable parts of the
plant's alarm notification system.
Process Control Services has extensive experience with our PLC and SCADA systems, which allows
them to effectively troubleshoot, diagnose and repair or reprogram our systems, As a locally based
company, they are the only vendor with the ability to be onsite at any of the facilities or lift stations within
minutes of receiving a request. As such, the City of Ocoee has issued purchase orders totaling $81,796
with Process Control Services this fiscal year, including emergency repairs, which brought the total
over the City Manager's approval level of $49,999.99
Issue:
Should the Honorable Mayor and City Commission approve Process Control Services as the Single
Source vendor for instrumentation troubleshooting and repair of the PLC and SCADA systems?
Recommendations:
Staff recommends approval of the Process Control Services as the Single Source vendor for
instrumentation troubleshooting and repair of the PLC and SCADA systems. Staff also recommends
that the City Manager be authorized to approve future purchases with Process Control Services up to
the limit of his purchasing authority for each purchase, not to exceed the budgeted amount, each fiscal
year.
Attachments:
None
Financial Impact:
As budgeted each fiscal year.
