AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION ENTERING INTO A
CONTRACT WITH AUTOMATIC SYSTEMS COMPANY TO UPGRADE
THE WATER SCADA SYSTEM
DISCUSSION: Introduction
The purpose of this agenda item is to seek City Council authorization to
enter into the City's Standardized Contract with Automatic Systems
Company to upgrade the City's current SCADA (Supervisory Control And
Data Acquisition) computer hardware and software system in the amount of
$30,944.
History
The SCADA system is the brain of the entire City's water system. The
system utilizes a software program named "Wonderware" for all operational
control of the City's water supply system and treatment operations. It also
runs the communication and security hardware systems for the water plant
and all off site components of the drinking water system. It controls items
such as monitoring the water tower levels and calling for additional water,
turning on wells and in what order, treatment filter conditions and triggering
backwash cycles, calling for water from the SMSC system, etc. The system
also has several alarm parameters built in to keep staff apprised if any
abnormalities arise. This is probably one of the City's most key control
systems since it controls and proptects a water system valued at over$100
million which serves over 9,000 accounts and 24,000 persons year around.
The system is built of software, Wonderware, running on a typical operating
platform that is customized through software programming to our
parameters. Due to the specialty nature of the system a vendor with
programming knowledge is used to complete any adjustments in the system
when they are periodically needed. One vendor is typically used for this
service because of the intiment knowledge of our system that is required to
most effectively complete the updates.
The SCADA system that is currently in sevice was purchased with the
construction of the water treatment facility in 2008 and consists of two
desktop computers and one touch screen computer in the WTF control
panel. The current computer runs the Windows XP operating system which
is no longer being supported leaving our system exposed to cyber risks.

The current version of Wonderware is not compatible with later OS versions.
Therefore if we update the OS to eliminate the risk, we must also upgrade
the Wonderware program. For planning purposes, these types of systems
should be upgraded on a 5-10 year cycle.
Current Circumstances
Upgrade of the SCADA system was planned for 2015, indentified in the
Water CIP and included in the operating budget. Quotes were obtained
from our vendor to replace the existing seven year old computers (2),
replace the WTP Control Panel, upgrade the software (3 licenses), upgrade
the alarm software, configuration of the software, and training. There are
three main components to this purchase, the hardware, software, and
programming/training.
There are three computers included in this purchase. Quotes were obtained
from Automatic Systems and reviewed by the IT department to compare to
our other computer supply vendors. Automatic Systems provided
comparable pricing and provides the benefit of obtaining a computer that is
matchedto the softwares specific needs.
There are two primary software vendors for water system controls,
Wonderware and Factory Talk. Although Wonderware tends to be slightly
more expensive the cost to have a programmer convert all of the operating
settings outweighs any cost savings. In addition, Wonderware has been
known to have a more robust customer support program and tends to be the
preferred software used in the water industry. The pricing provided by
Automatic Systems is a direct pass-through from the software vendor.
Automatic Systems has been our preferred vendor for our SCADA system
for over fifteen years due to the specific nature of the work. This is one of
those areas where it would be highly inefficient to switch vendors due to the
knowledgebase that exists with the existing programmer. A new company
would need to become familiar with the programming of the system taking a
significant amount of time.
Conclusion
Staff is recommending that the SCADA software be updated to limit any
operational risks or interruptions to this key system.
ISSUES: 1. As of April 2014 Microsoft no longer supports Windows XP or provides
any security updates. Thus, the SCADA computers are vulnerable and
at risk to cyber crimes.
2. The Wonderware Intouch software license as well as the alarm dialing
software license are several upgrade versions behind the latest
available today. The longer the waiting period to upgrade software
license, additional expenses are incurred. If we wait too long it might
require upgrade to an interim version to upgrade to the current.
FINANCIAL The 2015 Water Operating budget anticipated the upgrade of the SCADA
IMPACT: system and includes $40,000 to complete the project.
ALTERNATIVES: 1. Approve a resolution as part of the consent agenda entering into a
contract with Autmatic Systems Company to complete the SCADA system
upgrade.
2. Table this agenda item for a specific reason
3. Deny this agenda item for a specific reason and provide staff with
direction
