MEMORANDUM
TO: Todd Gerhardt, City Manager
FROM: Paul Oehme, City Engineer/Dir. of Public Works'~'
DATE: June 23, 2004
SUBJ: Consider Award of Bid, SCADA System - Phase
PW30'7D
REQUESTED ACTION
Consider awarding a bid for SCADA improvements, Phase I to Mark J. Traut
Wells in the amount of $49,100.00.
BACKGROUND
At the February 23, 2004 work session, staff discussed with Council the need to
upgrade the City's SCADA system. Over the last 3 years, the City has spent over
$90,000 per year to keep the current SCADA system operational. The proposed
water treatment plant will necessitate the upgrade of the current SCADA system.
The current system is unreliable and routinely gives false alarms which costs the
City overtime pay and requires additional time for utility department, keeping
them from other duties.
On March 22, 2004, the City Council approved plans and specifications for bids
for SCADA improvements, Phase I.
On May 10, 2004, the City Council awarded a bid for Well No. 9 improvements
and the construction of a raw watermain from the new Well No. 9 to Well No. 3.
Council also considered awarding a bid for SCADA improvements, Phase I in the
well drilling bid.
DISCUSSION
At the May 10, 2004 Council meeting, Council requested additional information
on the Supervisory Control and Data Acquisition (SCADA) equipment, as
manufactured by US Filter, for the Phase I improvements which was bid on April
22, 2004 along with the well drilling bid. The Phase I portion of the SCADA
improvements included the upgrade of the SCADA system at Well No. 3, the new
installation at Well No. 9, and the SCADA Master. The existing SCADA system
at Well No. 3 will remain in operation until the Phase II upgrades are complete.
The information Council requested centered on whether other parties could
support the US Filter product. Most SCADA systems on the market today have

the SCADA manufacturer selling the SCADA system to an integrator. The
integrator would then install, program, and maintain the system. This type of
approach has made SCADA networks for municipal applications mainly
proprietary since the integrator typically programs the system to their
predilection. The system the City has bid out would eliminate the third party
integrator. The manufactm'e, US Filter, would program, install, and maintain the
system. This approach ensures the programming will be written to international
programming standards so any programmer can look at the programming and
understand how it functions. Also, the guarantees included in the bid will reduce
the life cycle cost of the system. The platform this system provides is one of the
most flexible systems on the market. If the City chooses to install other
manufacturer's systems in the future, this system will communicate with the other
components seamlessly, in the unlikely event that the US Filter product is no
longer manufactured or supported, the City will have the ability to work with
other integrators for future expansion and maintenance of the system. Staff has
received a letter from an integrator indicating their ability and willingness to
maintain the City's SCADA system if the City chooses to look for future
operations and maintenance assistance.
The scope of the Phase II SCADA improvements will upgrade all the other
remote sites the City currently monitors with SCADA. This phase will evaluate
each remote unit the City cun'ently monitors, remove the outdated hardware and
software, and will install the new hardware and software. After the scope of the
Phase II improvements has been defined, Council will have the opportunity to
consider authorization of the project before the project is bid.
RECOMMENDATION
Staff recommends the City Council adopt the following motion:
"The Chanhassen City Council awards the Phase I SCADA improvements to
Mark J. Traut Wells in the amount of $49,100.00."
