AGENDA Smart City Review Smart Water Networks Traditional SCADA Systems Smart Water SCADA Questions Traditional SCADA Systems Supervisory Control And Data Acquisition • Type of industrial control system Industrial control systems (ICS) are computer controlled systems that monitor and control industrial processes that exist in the physical world SCADA typically are different from other ICS systems by being large scale processes that can include multiple sites and large distances Processes include industrial, infrastructure, and facility based Infrastructure Processes: • • • • Water treatment and distribution Wastewater collection and treatment Oil & gas pipelines Electrical power transmission and distribution Traditional SCADA Systems Typical SCADA Subsystems Human Machine Interface (HMI) • Processed data is presented to the operator Supervisory System • Gathers all required data about the process Remote Terminal Units (RTUs) • Connected to the sensors of the process • Help convert sensor signals to digital data and send data to supervisory system Programmable Logic Controllers (PLCs) • Used as field devices Communication Infrastructure • Connects RTUs to supervisory system AGENDA Smart City Review Smart Water Networks Traditional SCADA Systems Smart Water SCADA Questions Smart Water SCADA: “Welcome to the new era of SCADA, and goodbye to the days of basic supervisory control and data acquisition. Today’s SCADA systems are reaching into most every aspect of a water utility’s water distribution and treatment operations, for a true enterprise-wide methodology. And most every stakeholder in the enterprise can benefit if the utility is ready to harness his or her SCADA system’s power. All it takes is the time to investigate...” 1 Source: (1) Water Efficiency, “An Evolving System: Getting the most power from your SCADA”, May 2013, www.waterefficiency.net Smart Water SCADA Many Different Sources of Information are possible… ●FLOW / PRESSURE METERS ●GIS AND SCHEMATIC TOOLS ●ACOUSTIC SENSORS ●ASSET MANAGEMENT ●WATER QUALITY SENSORS ●PUMP OPTIMIZATION ●DATA LOGGERS ●HYDRAULIC MODELING ●SCADA ●WORKFORCE TOOLS ●AMR/AMI ●LEAK DETECTION SOFTWARE ●UTILITY DASHBOARDS ●ALERT SYSTEMS Smart Water SCADA High Schneider Electric SCADA Offering Customization OASyS Low ClearSCADA System Integrators Deployment Direct Smart Water SCADA Geographical Information System-based solutions that provide a single version of the truth—supporting coordinated decisions across a utility’s entire enterprise Asset Management can drive more data that managers can use while breaking down the typical silos that exist within a utility. Water network management through data collection, measurement and analysis—ensuring optimal efficiency, longevity and reliability Energy and process management to help meet demand, maximize resources, reduce costs and emissions, and ensure regulatory compliance Water loss management and leak detection using real-time data and model network simulations to identify and resolve problems—improving service SCADA + GIS Schneider Electric | Jeff M.

Ties static data such as asset location with status info in the SCADA Provides a key link between supervisory operations and business decisions SCADA + ASSET MANAGEMENT Schneider Electric | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31st, 2014 21 SCADA + Asset Management Can drive more data that managers can use while breaking down the typical silos that exist within a utility. Allows important information to be shared across departments. Can help achieve a city’s energy efficiency goals by monitoring key assets at each plant. Key assets could be ones that use a tremendous amount of energy such as pumps and blowers. Dashboards with KPIs listed can help determine which assets to focus on. SCADA + Asset Management - Des Moines, IA Their (Des Moines) initial plans were to optimize performance of assets that are energy hogs (blowers and pumps) but they discovered that, in the case of four of their 2,000 hp blowers, just knowing which units were operating most efficiently and using those units as the primary air movers provided results that exceeded their initial project goals. Just understanding what they were already doing well contributed significant returns. Being able to detect process deterioration is also of high value, which the KPI dashboard can alert them to. This integration has resulted in annual energy savings of $40,000 at one plant alone. SCADA + HYDRAULIC MODELING Schneider Electric | Jeff M.

Smart Water SCADA Benefits Helps streamline daily operations and maintenance and improves network water loss management system planning. Solutions are scalable, providing sustainability solutions for water utilities of nearly any size. Water utilities can automatically extract data from different systems and calculate performance indicators that accurately and objectively represent water network performance. Finally, with these benchmarks , the utility can communicate performance measures in a consistent manner to all stakeholders.
