Portsmouth Water deploys arboricity™

Portsmouth Water partners with Inflowmatix to deploy arboricity™ at the core of its ‘Digital Twin’ strategy

Inflowmatix has worked collaboratively with Portsmouth Water to provide support throughout the Covid-19 crisis and to strategically develop and trial its new product and service offerings. Providing online, automated analytical tools to monitor critical assets such as pressure reducing valves (PRVs) which feed large pressure managed areas (PMAs) has enabled a substantial improvement in key customer metrics in the first year of the AMP7 period. Both Leakage at 23Ml/d and Interruptions to supply at 2 mins 49 seconds are at their lowest levels in recent history – this being achieved against a backdrop of some extremely challenging supply periods with both Covid and a cold winter.

The Inflowmatix high frequency technology not only captures and localises significant pressure events within a network using leading edge analytics but now enables calibrated, and near-real time maintained hydraulic models as a core element of its arboricity™ ‘service’ based offering. Such models allow higher level automated analytical services to be brought online which are cognisant of the hydraulics of the network and therefore not ignored, increasing confidence in operational decision making and providing actionable insight.

Integrating these models with the Innovyze WS Pro and IW Live core modelling platform has created the heart of a Digital Twin providing live network information at the point of need.

Working collaboratively with Inflowmatix to understand our network in more detail and to mitigate the effects of dynamic pressure variations has proved highly beneficial and has positively impacted our performance in the first year of a very challenging AMP7. We could not have delivered our historically low leakage performance in particular without the timely insight into network performance that working with Inflowmatix gave us. Our strategy to continue to improve this performance relies on harnessing this insight even further and we are doing this by putting a digital twin, using arboricity™, at the core of our operations. We are delighted to be taking this next step of the journey working closely with Inflowmatix

Jim Barker

Head of Water Resources, Leakage and Smart Networks – Portsmouth Water Ltd.

UK’s largest smart water network pilot could revolutionise service in Yorkshire

yorkshire water

Yorkshire Water is starting the largest and most extensive smart water network pilot in the UK, collaborating with 15 companies in the digital water space to further improve the essential water supply service it provides to customers.

The ambitious multi-stakeholder collaboration combines data from its acoustic, flow, pressure and water quality monitors and aims to reduce leakage and burst levels in the pilot area in West Sheffield. Fifteen companies in total will be involved on the collaboration, including: Stantec, BT, Xylem, Itron, ATi, Inflowmatix, HWM, Gutermann, Technolog, Servelec/Primayer, Connexin, Arqiva, MUS and Syrinix.

The scope of the industry-wide collaboration is to test the latest cutting-edge digital water meters, sensors, advanced analytics and telecommunications channels.

Yorkshire Water is hoping that the pilot, which will use data received at near real time from across its network, will revolutionise the way it manages leaks and interruptions to supply in the future and therefore reduce the amount of water taken from the environment.

Yorkshire Water Innovation Programme Manager, Sam Bright said: “Technology has progressed so much over the past few years that we are now able to combine more data streams than ever before and push the boundaries of what is possible using artificial intelligence. It really is an exciting time to be at the forefront of translating these advances into real value for our customers.”

The smart water network pilot will integrate the rich data from multiple new and existing sources and present it in a single visualisation platform. This will provide a virtual model of the physical assets across the network referred to as a digital twin. Through the use of machine learning and artificial intelligence, clustering data sets and removing false positives, this will inform asset and operational decision making. Analysts in Yorkshire Water will be able to prioritise repairs instantly, enabling leaks to be repaired quicker and reducing water lost. The digital twin will have live hydraulic modelling capability integrated to sensor data in the field which will be used in real-time to assess the impact of an incident or network anomaly and to provide an informed operational decision support tool.

Damian Crawford, Head of Smart Networks and Leakage at Stantec said: “We are very excited about partnering with Yorkshire Water in delivering this innovative pilot and developing the five layers of smart architecture all the way from designing the physical asset layer through to developing data analytics to support the desired business outcomes.”

The 12-month pilot and the outputs will be used as part of the wider Yorkshire Water’s digital strategy to determine future dynamic control and system optimisation capabilities.

Yorkshire Water to deploy 650 InflowSense™ high frequency pressure measurement devices as part of an extended trial of the InflowSys™ Edge platform.

press release jan 2020

Inflowmatix is delighted to be working collaboratively with Yorkshire Water to help deliver their Ofwat leakage commitments as they transition from AMP6 to AMP7 and look to maintain upper quartile performance.

Inflowmatix has developed InflowSys™ Edge which combines high frequency pressure sensors with local analytics capability alongside enhanced data platforms. This system provides water utilities with the insights to better understand the behaviour and the performance of their water distribution networks. As a consequence, utilities can improve their actions on asset management and mitigate the likelihood of failure of critical parts of the network by optimising the overall pressure in their network.

Deployment of 650 InflowSense™ high frequency pressure measurement devices will be rolled out as part of Yorkshire Water’s Intervention Enabling Networks (IEN) project across a significant number of DMA’s (District Metered Areas). The InflowSys™ Edge technology which uses high accuracy time stamped pressure data from the InflowSense™ device not only delivers burst/leak localisation but is critical to accelerate and understand the root cause of high frequency dynamic pressure variations (including but not limited to, transients) in order to fundamentally “calm” the network behaviour.

Yorkshire Water Innovation Programme Manager, Sam Bright, said: “Reducing leakage is a key priority for us at Yorkshire Water and we are excited by the potential of the InflowSense™ devices and the benefits they will bring to the network and our customers.”

Robin Bell, COO at Inflowmatix said: “From the first interactions with Yorkshire Water we could see there was a close match between their aspirations and our unique capabilities. We’ve enjoyed the first stage of our collaboration and look forward to close working with Sam and the team at Yorkshire Water in achieving their challenging objectives for AMP7 and beyond.”
