WATER & WASTEWATER ASIA March / April 2018 FROM THE GROUND / 29 Figure 2: A trace of events at several sensor sites where unusual system operations may have led to leakage One of the platforms they use is a real-time monitoring water distribution system called View™. It can be used by utilities to improve system management and operations by providing integrated measurement and analytics. As a platform, View allows water utilities to better understand the behaviour of their distribution network and thus improve its planning, water usage and operation. This includes reduced response time to events such as water leaks and bursts, improved operational planning and associated efficiency savings. View was successfully deployed in a major city in Asia for a large water utility. The platform was linked in to the utility’s SCADA system to exchange sensor data and was operated remotely. The platform provided the utility’s water supply network operations and planning teams with decision support services including event detection (leaks, bursts), system modelling, demand prediction and operational simulation. It has successfully detected several pipe bursts through pressure transient sensors, and numerous pressure abnormalities relating to both planned and unplanned system operations. In Figure 1, it shows an example of several sensors within the vicinity that detected a break that was traced back to a large main. A post-event analysis helps trace back the sequence of events before a confirmed leak or burst event to understand which operations may have contributed to the leak. Figure 2 shows a trace of events at several sensor sites where unusual system operations may have led to leakage. As a result of using this innovative technology, and having access to accurate measurement data, the water utility has been able to see the characteristics of many normal and abnormal events. Real-time email alerts and data visualisation have helped them to identify operation inefficiencies, perform remedial actions and immediately validate the results of these actions. The real-time data has given informative feedback to help quickly isolate complaints of low pressure in high consumption areas, saving time and frustration. View has also supplied the utility with a real-time hydraulic network model that has provided an up-to-the minute view on demand and consumption in the network. To more efficiently operate and manage water distribution systems, it is important to not just intelligently increase the amount of measurements being made within the system, but also to use intelligent analytics to extract information from the data. A smart water network will allowwater utilities to better manage their infrastructure from source to consumer through improved monitoring and data analysis. A state-of-the-art smart water solution supplying real-time data can provide utilities with savings of up to millions of dollars annually. Safe-guarding precious water resources whilst making intelligent business decisions can be achieved by forming intelligent partnerships between people and technology. WWA
