1 NuRON Water Network Monitoring Detect problems in real time before they turn into headaches

2 The SEW Journey Non Revenue Water o Proactive Acoustics since 2003 Walkers/Listening Sticks (10m range) Correlators ( m range) o Extended Drought o Reactive to leaks Customer Alerts Perception of wastage during drought

Correlators (100-200m range) o Extended Drought o

3 The SEW Journey DSE Grant o $300,000 Permanent Monitoring System o Pre-Trial 216 Lots 2x NuRON, 4x Pressure o Extended Trial 835 Lots 6x NuRON, 4x Pressure, 16 Accoustic

4 Leak Detection Trial Permanent Installations o NuRON Station Technology o Generation of virtual water supply zones o Minimum Night Flows (MNF) trends o Overnight acoustic noise trends o Developing automated reporting systems

zones o Minimum Night Flows (MNF) trends o Overnight

5 Leak Detection Trial Data o Data available with detail not previously possible

6 Leak Detection Trial Accuracy o Detect low flows 5-10L/min

7 Leak Detection Trial Accuracy o Mag Flow Drop Out

8 Leak Detection Trial MNF o Trends Per Property Basis

9 The SEW Journey Technology Assessment Results o Flow Monitoring proved best for leaks/bursts o Pressure good supporting information Performance Evaluation Monitor Type Detect Onset of Leaks Detect Burst Events Comments Acoustic Poor Poor Flow/ MNF Analysis Good Excellent Pressure Poor Average Provided misleading results or did not detect events Did detect and alarm at changes in MNF preceding events. Provides good indication of burst locations during burst events. Not effective at detecting leakage propagation. Provides good operational data and an indication of burst locations during burst events.

Provided misleading results or did not detect events Did detect and alarm at changes in MNF preceding events.

10 The SEW Process Active Leak Control Framework DMA Creation Flow Meter Installation Data Analysis and Insight Field Surveys Repairs

11 NuRON Technology Operational and Networks Monitoring Benefits o Peak day zone performance o Virtual water supply sub-zones o Consumption analysis o Alarms at critical network locations o Water quality

12 NuRON Technology o Data collection for network model calibration o Critical/Large Customer (similar to Hydroshare) - usage volumes and profiles - customers can self monitor usage o Leakage Detection (Reduction in Non- Revenue Water) - MNF Analysis, - overnight acoustic response

profiles - customers can self monitor usage o Leakage Detection

13 The Solution Integrated Monitoring o Flow, Pressure, Acoustic, Data Logger

14 The Solution - Battery powered stations (up to 5-10 year battery life) - Utilises mobile telephone networks - Data collection, storage and relay capabilities - Real time alarms - Multiple data inputs (flow, pressure, temperature, water quality, pit lid status, etc.)

storage and relay capabilities - Real time alarms - Multiple data

15 The Solution - Acoustic sensing (standalone monitors incorporated into system) - Automated reporting - Easily retrofitted to existing assets - Fully IP68 rated (can be fully submersed in water) - Lockable pits - Web based user dashboard

retrofitted to existing assets - Fully IP68 rated (can be

16 The Benefits Operational Insight o Water zonal leak detection o Low cost installation o Real time water quality and pressure management o Low maintenance o Flexibility in installation

17 The Benefits Low Cost o Traditional SCADA site would be 30k+ o Equivalent NuRON site is: Pressure Site -> $3k-$5k Flow + Press ~ $11K

18 The Results o Multitude of low-powered, real-time monitoring systems deployed on a large scale throughout the water and sewer networks to read pressure/flow/water quality o Previously cost prohibitive, but new technology has paved the way

water and sewer networks to read pressure/flow/water

19 The Results o Virtual DMA s Varying Size o All the benefits of a physical DMA without the problems of valve management Water quality

20 Conclusion o Increased monitoring using low-powered micro processing equipment in the field. o More data opens up new ways of operating and designing networks o Impacts many business units such as operations, asset management, planning and leak detection.

o More data opens up new ways of operating and designing
