3. What drives cities to become smarter?

   “A smart city is characterized by the integration of technology into a strategic approach to sustainability, citizen well-being, and economic development.”
4. The Energy challenge and the cities …and by 2050 Citiestoday… Earth’s surface World population World population Years to double the urbancapacity developed over the past4,000 years Global energy consumption Global CO2 emissions
5. Cities must become smarterby becoming more efficient, more sustainable and more liveable Better information sharing Increased control over city systems Liveable Sustainable Efficient Reduced Carbon emissions and energy consumption Decreased need for massive infrastructure investments Higher quality of life for city residents Increased global competitiveness

7. The Drivers for Smart Water Networks Rapidly Rising Urban Population Efficiency! Smart City Drivers Growing Pressure on Infrastructure Increasing Scarcity of Resources Economic Pressure on Cities Rising Consumption Levels Effects of Climate Change Demand for Better City Services Increasing Threat of Water Hazards e.g. Urban Flooding Need for Dependable, High-Quality Water Increasing Water Consumption Pressure to Improve Efficiency & Reduce Operational Costs Smart Water Networks Drivers Inefficient, Overloaded & Aging Infrastructure Increasing Scarcity of Water Supplies

10. Why Change How We Operate? Total energy consumption of U.S. water utilities is estimated to be 56 billion kWh, equaling $4 billion annually in operational expenditures1. California’s water and wastewater utilities energy consumption comprise 19% of the total energy usage in that state2. Between 5-10 billion Kw/h of power generated in the U.S. is spent in water that is either leaked or not paid for by customers3. The U.S.G.S. estimates that water lost from water distribution systems is 1.7 trillion gallons per year at a national cost of $2.6 billion per year4 Sources: Environmental Protection Agency (EPA), “Ensuring a Sustainable Future: An Energy Management Guidebook for Wastewater and Water Utilities”, 2008 California Energy Commission. “California´s Water- Energy Relationship.

12. 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
13. 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

15. 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: Water Efficiency, “An Evolving System: Getting the most power from your SCADA”, May 2013, www.waterefficiency.net
16. Smart Water SCADA Many Different Sources of Information are possible… Flow /Pressure meters Acoustic sensors Water quality sensors Data loggers SCADA AMR/AMI Utility dashboards GIS and schematic tools Asset Management Pump Optimization Hydraulic Modeling Workforce Tools Leak Detection Software Alert Systems

18. 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
19. SCADA + GIS
20. SCADA + GIS Display of SCADA on GIS screens or vice versa can easily be accomplished. Ties static data such as asset location with status info in the SCADA Provides a key link between supervisory operations and business decisions
21. SCADA + Asset Management
22. 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.
23. 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.
24. SCADA + Hydraulic modeling
25. SCADA SYSTEM WATERWORKS DISTRIBUTION NETWORK 20 % 80 % INVESTMENT
26. SCADA + Hydraulic Modeling Better overview and improved operation of water distribution system By using live SCADA data a hydraulic model can be transformed from a planning tool to a decision making tool Quick assessment of required action Not dependent on specialists
27. SCADA + Hydraulic Modeling Pressure Control Reduction in loss of water Reduced number of new leaks Less use of energy for pumping Less CO2 emission Less wear on pumps Graphical overview of zones Quick reaction Correct and qualified reaction Contingency Planning Expected savings 10% reduction or more in NRW ROI in 18 months is common
28. Scada + AMR / AMI
29. SCADA + AMR / AMI AMI extends current advanced meter reading (AMR) technology by providing two way meter communications, allowing commands to be sent toward the home for multiple purposes, including “time-of-use” pricing information, demand-response actions, or remote service disconnects. Improved understanding of water consumption and flow patterns Increased revenue (less unaccounted for water) Reduced meter reading costs Provides outage detection and management
30. SCADA + AMR / AMI Could be accomplished through a performance contract Depends on a utility’s existing level of non-revenue water AWWA Water Audit Form Water Supplied Authorized Consumption Water Losses System Data Cost Data Additional Info (leak detection capabilities, SCADA, etc)
31. Scada + leak management

35. Other Efficiencies Multi-Utility SCADA Systems Streamlined service support Common spare parts Training Customer examples: Burbank Water and Power – Burbank, CA Combined electric / water applications Baltimore Bureau of Water & Wastewater Moving to a common SCADA platform
36. You Can’t Manage What You Can’t Measure The water industry encourages utilities to develop and use KPIs to identify areas of improvement, define realistic targets, design action plans, and track improvements over time.
37. 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.
