MEETING DATE: February 2, 2022
TO: Board of Directors
FROM: Roe Vernon, IT/SCADA Engineer
SUBJECT: Water SCADA Operator Interface Terminal Replacement
APPROVED BY_____________________________
Brian C. Wright, General Manager
RECOMMENDATION:
Authorize the General Manager to execute a contract with AVEVA Select California to
provide thirty replacement operator interface terminals (OITs) in the amount of $41,550
plus a ten percent change order allowance for a total not to exceed $45,705.
BACKGROUND:
In 2012, the District embarked on the Water Supervisory Control and Data Acquisition
(SCADA) Replacement Project. The purpose of the project is to replace the aging and
proprietary Sandel-Avery water SCADA System. SCADA Systems generally last thirty
years and components are upgraded or replaced as needed or have run their useful life.
OIT’s, are computer interfaces tasked with a specific function in mind. They are designed
for utility operator use, enabling key adjustments to utility operating parameters. The OITs
provide access to specific data and functions in a manner that allows the operator to collect
information or implement programming changes without requiring logic control
programming expertise.
When the District’s SCADA replacement project began, the original OITs ran the current
operating system (OS), Microsoft’s (MS) Windows Embedded 7. This version is no longer
supported for critical security updates. The recent OS upgrade includes MS Windows 10
LTSB, requiring larger OIT hard drives. The new OITs specifications will include an
increased hard drive capacity (256GB), sufficient to support future OS upgrades when it
becomes necessary.
