1 Smart Water Infrastructure Solutions Overview Craig Collins January 8, 2015

2 1 LANDSCAPE OF AMI

3 The Utility Landscape A Historical Perspective Demand grew as new houses were built and existing homes were modernized Utility assets funded in part by grants New assets over-shadowed repair and replacement of existing ones The Current Landscape Per capita demand is decreasing Public support for rate increases is rare Utilities responsible for capital costs Repairing/replacing underground assets is a critical need The true value of water is slowly being recognized by the general public. Partly in due to recent droughts and water scarcity. 2

4 The industry has convinced the public that clean water is relatively inexpensive and readily available. -AWWA 2010 Rate Survey 3

5 Water Utilities: Stakeholders & Issues Utility Operations Customer Community Lower costs (improve business operations) Understand and monitor water usage and cost Outreach and education Increase distribution efficiency More data on actual usage in home Conservation and stewardship Increase cash flow Opportunities to conserve Water Awareness Change the customer s perception of the utility's operations and processes Need more vital data on operations High bill complaint resolution Improve the customer experience Provide more with existing staffing levels 4

9 AMI Solution Goals Utilities Needs : Increased billing department efficiency and accuracy Reduced customer service calls Empower customer service reps with more information Meter right sizing and trending Engineering can better evaluate proposed system enhancements Non-Revenue Water calculations and advanced analytics Distribution system and delivery point leak detection and repair Water conservation programs and enforcement Improve the customer experience 8

10 AMI Headend Data and Operation Operates and manages the network Provides basic user interface Billing and consumption information per account Includes analytics for Network troubleshooting Delivery point leak discovery Usage pattern changes No flow Reverse flow Meter tampering Theft of service 9

11 Integration with the Enterprise Utility Personnel CIS/Billing Consumer Engagement MDM and Advanced Analytics Metering Ops & Work Force Management AMI Headend Solution Data Warehouse AMI Network 10

12 Consumer Portal: Bill Comparison Customers compare water bills Find out why they vary month to month and year to year. 11

13 Consumer Portal: Customer Goals and Alerts Ability for customers to set goals and receive alerts Weekly Bill to date Usage or Cost Threshold Encourages customers to take action , web, mobile device, IVR, AMI 12

14 Mobile Application Information on-demand, from anywhere Low cost/high impact channel Instantly available and highly personalized On-device consumer alerts Motivates higher savings levels Your Water Usage Lawn Irrigation Finding Leaks Your Highest Usage Consumers can request ideas on approaches to savings and can review detailed consumption data for clues that suggest where to save 13

15 Revenue Assurance Applications Analyze meter data to generate a list of suspect accounts or meters Meter configuration issues Meter malfunctions Key statistics produced by account, all user defined Working lists by user Leak detection Theft detection Water restriction monitoring Displays the user- selected customer attributes Usage on seasonal accounts Track the state of an account 14

16 Meter Data Management Read Data Missed Reads All Accounts Consumption Never Zero Non-Numeric Read High/Low Consumption Leak Detect Flag (constant Consumption) Backflow Flag (negative consumption) No Flow Tamper Cut Wire Meter Failure VEE Total System Consumption Aclara Technologies LLC

17 Advanced Analytics Offerings Closed Accounts Meter Trending (Active Low or High Usage) Inactive Accounts with Consumption Water Balance Meter Right Sizing Historical Analysis District Metering with potential loss Aclara Technologies LLC

18 Future Objectives of Smart Water Infrastructure Level Monitoring for Lift Stations and Manholes Distribution Pressure Monitoring Water Quality Monitoring AMI/SCADA Integrated Systems Integrated Mobile Workforce Management 17

19 Distribution Management Component A two-way communication system adds value way beyond metering Remotely monitor system operations and performance Distribution level leak detection provides Early Leak discovery Protection of Utility and Customer owned assets Protection of public health Scheduled line outage and repair Increased utility staff safety Availability of required repair material and equipment 18

20 The Ideal Water System In a perfect world,100% of the water that enters a system would be accounted for and billed. Water In Water Out = 100%

21 The Less Than Ideal Water System There will never be a 100% transfer of water usage from when the water leaves the water tower to when it reaches the customer. Water In Water Out = 80% As water travels through the system, leaks and breaks in the main lines will affect the utility and the bottom line.

22 The Less Than Ideal Water System There will never be a 100% transfer of water usage from when the water leaves the water tower to when it reaches the customer. Water In Water Out = 70% As water continues through the system, distribution connections, hydrants and an increasingly aging, stressed infrastructure adds to the losses. Meter inaccuracies and improper sizing compound this problem.

23 The real water system? There will never be a 100% transfer of water usage from when the water leaves the water tower to when it reaches the customer. Water In Water Out = 60% At the customer s premise supply lines leak prior to a meter point, within the premise even small leaks are magnified by the mass of the population.

24 The ideal water system There will never be a 100% transfer of water usage from when the water leaves the water tower to when it reaches the customer. Water In Water Out =?% Our aging infrastructure and expanding systems will require significant investment. Full replacement is impossible. Capital improvement projects must be scheduled and budgeted for.

25 Leaks The Hidden Water Loss As devastating as a water main break can be, these are not what water utilities are continually fighting against.

26 Leaks The Hidden Water Loss Typically, breaks such as these do not happen in an instant. A small growing leak has usually been active for weeks, months or years The high impact of water loss has already occurred when discovered by more visible means.

27 Leaks The Hidden Water Loss Impact of Leaks: Resources: water conservation and environmental efforts Revenue: losses for the utility and reduced in capital dollars for infrastructure investments Rates: increases for the customer for cost of water not put to use Safety: undermining roadbeds, reducing delivered quality Trust: loss in trust is a loss in support

28 Leak Detection, A Pre-Emptive Conservation Tool

29 Leak Detection Remotely Monitored and Correlated Leak Detection Sensors placed on distribution lines every 500-1,000 Acoustic monitoring occurs during off peak hours System intelligence eliminates false positives Cost-effectively identifies small leaks before they become major problems Correlation allows the utility to pinpoint the leak location within

30

31 Cross-Correlations Pinpoint Leak Location Well-defined peak places the probable leak between logger and logger (using default distance of 2,000 feet between loggers) 30

32 Enter Specific Pipe Information When a probable leak is identified, enter specific pipe parameters (distance, material and diameter) for that segment to get true leak location. 31
