Utilities Need Better Pressure Intelligence Software
High-rate pressure sensing integrated with state-of-the-art analytics – for improving asset life through reducing stress on pipes – keeping the network surge-free and calm.
Water supply networks face pipe failures that range from small service connection leaks to catastrophic transmission main bursts. The IWA has identified that many of these failures occur due to frequent high amplitude variations in pressure known as pressure transients or water-hammer events. Such variations stress the pipes and joints, cause pipe material fatigue and act to reduce the effective age and useful lifespan of the distribution network assets. If there exist small leaks on such pipes, pressure transients worsen them. Even newer infrastructure may fail if the pressure transient patterns are sufficiently intense. These pressure pulsations are caused by switching on and off of pumps; actuation of valves with short opening and closing times; flow rate fluctuations due to large customer consumption activities, construction as well as seismic vibrations.
Frequent Transients with up to 140m magnitude due to pumping operations showed

- Save CAPEX – Identify failure-prone points in network for proactive asset management.
- Optimize operational costs - prioritizing fixes.
- Extend Asset Life – Identify cause and location of damaging transients and excessive stress being applied to the pipelines, which reduces the life of your assets.
- Reduce rehabilitation costs dramatically – Targeting only the areas in need of maintenance.
- Identify high-risk assets – Early and targeted intervention/damage prevention for deteriorated/deteriorating sections.
- Provide evidence of damage caused by transient events.
- Identify even tiny changes in system operation that could be an early warning of something wrong or changed.
- Manage your pressures, optimise pressure to reduced transient effects.
- Understand how your pumps are performing.
- Understand who, what, when and where is causing your damaging transient events.
- Education of customers and operations in reducing their activities that are causing transients.
- Monitoring valve operations automatically (when/where valves have been operated).
- Know the position of valves (open or closed) - especially DMA boundary valves.
- Know exactly when and where critical boundary/ Pressure boundary and DMA valves are operated.
- Know how your pressure management is really performing in high resolution of up to 256 samples per second.
- See such minute changes that low resolution pressure monitoring cannot see.
- Learn the optimal minimum pressure reduction to reduce transient effects.
- Allow SurgeView™ to be your pressure manager.
