Real-Time Pipe Breakage Detection
Real-Time Pipe Breakage Detection
Advanced High-Rate Pressure Sensing Integrated with Cloud based Analytics
Visenti’s LeakIntel™ system is comprised of high-rate (250 samples/sec) pressure sensors installed at optimal locations. These sensors transmit continuous information about the condition of the pipe network to a Cloud-based data management and analytics engine.
The LeakIntel™ system identifies the pressure transients generated by potential pipe breakage and localizes the event to the faulty pipe with high likelihood.
High-Rate Pressure Sensors catch pipe break events 24/7 in Real-Time
When a pressurized pipe breaks, it releases a high-rate pressure transient that propagates along the pipes in very high velocity. LeakIntel™ is a unique system that can capture these short-term leak related transients before they are dampened. It localizes to the faulty pipe and prioritizes the pipe failure criticality (leak magnitude & impact on consumers) to allow immediate & timely response with minimum impact on network integrity. Distractions are minimized, because this real-time intelligent machine learning system filters out false alerts.
LeakIntel™ is an automated system supported by Visenti’s 24/7 Control Center. Once a critical leak event is identified, Visenti’s Control Center is activated to respond to the alert and the most relevant network operators are notified.
Pipe Repair Operation Simulation and Impact Assessment on Mobile Plateform
A leaking pipe can be difficult to isolate and repair. In dense pipe networks, it can take significant amount of time to identify an appropriate set of valves needed for isolating the leaking pipe. It can also be tough to assess the impact of the unexpected pipe isolation on the rest of the network.
LeakIntel™ incorporates the network GIS data, pipe network model and live pressure data to automatically identify the locations of the valves needed to be shut-off in order to isolate the leaking pipe. And if a valve is faulty or stuck, LeakIntel™ instantly identifies alternative valves to shut off.
This system also notifies in case there is a negative impact on the rest of the network such as low pressure or interruption of supply to key customers. This prevents unintended consequences of the repair operation.
LeakIntel™ is available on mobile devices too; all the simulations can easily be done while in the field, during the operation. This saves time, money and minimizes damage to the environment from trial and error.
Case Study: Singapore’s Central Business District (CBD)
Singapore’s national water supply agency, PUB, has implemented Visenti’s pressure monitoring and leakage localization tools in the complex pipe network of downtown Singapore. This CBD network comprises 300 km of pipes spread around an area of 60 ㎢ and delivers 40 MLD of potable water to approximately 0.5 million customers.
Processed data from 35 pressure-monitoring/ leak-detection devices, deployed in optimized locations within the CBD network, enable the system, which manages pressure data streams, performs real-time analytics and sends SMS and Email notifications in real-time to the relevant field teams so that they can prioritize their operations based on the event severity and respond quickly to critical events to minimize any negative impact on consumers.
Since its implementation in April 2013, the system has detected critical pipe bursts. In these events, it has been able to localize the leaks within a 20-meter accuracy. The ability to detect leaks 24/7, even before they reach the surface, together with the ability to pin-point these leaks with existing complementary acoustic loggers, provides utility operators with vital lead time for operational planning and prioritization.
