The document summarizes the city's SCADA system and proposes upgrading the aging man-machine interface (MMI). It outlines that the SCADA system monitors and controls 26 sites added over 8 years, allowing operation with fewer staff. A new MMI is needed as the existing one is 15 years old and unsupported. The city solicited proposals and selected Reynolds Company to provide a turn-key installation over the next year, keeping the existing system functional during integration and providing improved documentation for the new interface.

2. SCADA Overview
• Supervisory Control and Data Acquisition
• Monitor, control and collect data from 26 sites
– In the last 8 years, we have added:
• 5 large Caterpillar emergency generators
• 4 new water wells
• 4 new sewage lift stations
• Reclaimed water system w/500,000 gallon tank
• A third wastewater treatment plant at Carter Lake
• Physical security at critical facilities (post 9/11)
• A second set of high service pumps at Dowling Road
• Allows us to staff sites only during working hours
– Saves at least 16 operators, approx $750,000/year

3. SCADA MMI
• Man-Machine Interface is what the Operator sees
• Existing MMI is 15 years old, no longer supported
• New MMI is essential
• Solicited proposals and interviewed 4 companies
• Selected The Reynolds Company and Factory Talk
• Installation and integration will take about a year
– Original concept was self-install, but Vendor turn-key is essential
• Existing system will stay fully functional
• New MMI will be documented and understandable
