PHASE 2, PUMPING STATION SCADA SYSTEM
RECOMMENDATION:
That Council wave the tendering process and single source the software licensing and
radio communication systems from ITT Flygt to complete the pumping station
Supervisory Control and Data Acquisition (SCADA) System phase 2 at an approximate
cost of $205,200.
BACKGROUND:
From 1999 to 2002, the City of Kitchener looked for a replacement to the proprietary systems for
data acquisition and control it had been using at its 23 sewage pumping stations. A key
requirement of the system was one that would allow city operators to set system parameters
without the intervention of the manufacturer or an outside programmer. A number of systems
were reviewed at the time. The Flygt Aquaview System was the only system that met this
requirement.
In the spring of 2003, Conestoga-Rovers & Associates conducted an extensive review of the
City's wastewater pumping stations. The study contained a list of improvements to be made at
each of the City's pumping stations. The report also contained a recommendation that a Flygt
FMC controller be installed at each existing and all future pumping stations. That
recommendation was the first step in the process of implementing a full featured Supervisory
Control and Data Acquisition (SCADA) System to manage the City of Kitchener's wastewater
system.
The implementation of the system was to be conducted in two phases. Phase 1 was to focus
on updating the equipment and buildings at each of the pumping stations. It included installing
Flygt FMC controllers at each station. Phase 1 also included a preview for the future
implementation of the SCADA system. A pilot version of SCADA application was installed on a
server at one of the stations. Limited licensing allowed the server access to a maximum of two
stations.
Phase 2 was to focus on data collection and central control. The 2003 budget allocated $1 .3
million dollars to phase 1 improvements of which $150,000 was allocated for installing the
controllers. No provisions were made for phase 2. By 2005, when Conestoga-Rovers provided
a follow up report, nearly all of the City's pumping stations had Flygt FMC controllers installed.

While still focusing on the individual pumping stations, the report contained a recommendation
to start implementing phase 2 - Central Control. Phase 2 would connect all of the pumping
stations to a central server. It would also change the alarm delivery mechanism because the
central server came with a front end alarm handler. The report estimated $72,000 as the cost
for implementing phase 2. The report underestimated the cost of the upgrade because it didn't
provide for a communication mechanism between the pumping stations and the central server.
In 2006, all pumping stations had Flygt FMC controllers installed and we were now ready to
implement phase 2 to by linking all facilities into a central server.
REPORT:
The Operations Division would like to complete the process of implementing the SCADA
solution to manage its wastewater system by implementing phase 2 of the project - Central
Control.
The recommended SCADA system is the Flygt Aquaview System. To complete this section we
require the purchase of the software licensing for Aquaview along with the MTC Com which is
the central server and alarm handler for all the facilities. The recommended method of
connecting the server and pumping stations is spread spectrum radio. The recommended
spread spectrum supplier is Phoenix Contact via ITT Flygt. To complete this section we need to
purchase the radio transmitters/receivers for each facility and the City Hall central server.
We would be by-passing the normal tendering process to complete this SCADA system
because Flygt is the only supplier of the software for the installed FMC controllers and the radio
system for the communications would be supported and warranted by Flygt as a complete
package.
FINANCIAL IMPLICATIONS:
This project will be funded from the Sanitary Utility through the Capital Pumping Station
Maintenance account. The approved 2007 capital budget contains a $200,000 allocation to
fund this project and an additional $250,000 allocation for general maintenance and other
improvements identified in the 2003 CRA report. Funding requirements beyond the $200,000
for this project will be drawn from the maintenance portion of the allocation.
The cost breakdown is as follows:
1. $11 0,000 Flygt Aquaview SCADA System
2. $ 80,000 Radio communications equipment
3. Taxes (PST) = $15,200
Specified costs include the following:
1. Flygt Aquaview SCADA System
· Server software license for 50 sites
· Client software license for 5 users
· Setup labour costs for 12 days
· Training for 1 day
· Two MTC-COM communication units
2. Radio communications equipment
· 30 radio transceivers, antennas, cabling, and interface cards
o 23 pumping stations
o City hall (2 units)
Report No: CSD-07-056

o Region of Waterloo and Manheim water towers (2 units each)
o 1 spare lot
o 1 day training
COMMUNICATION:
The acquisition of the full SCADA System has been reviewed and approved by our I.T. Division
and Community Services, Operations through a business case (attached). The request for
waving of the normal tendering process has been reviewed and approved by Larry Gordon,
Director of Purchasing.
CONCLUSION:
Implementing the full SCADA system by adding central control will complete the
recommendations brought forth through the 2003 CRA report bringing many benefits to the city
including: service quality improvements, reduced maintenance costs, lower monthly
communication costs, and reduced risk of environmental spills The cost will be justified by the
benefits.
