A smarter water future

Andrew Welsh, of Xylem Water Solutions UK, talks about how we can future-proof water productivity, quality and resilience with smart networking.

Water and wastewater managers are facing acute infrastructure challenges. These include pipe leaks, mains bursts, sewage and storm water overflows, as well as energy-intensive operations coupled with the insufficient data to aid in efficient decision-making and management of assets. In conjunction, cities are expanding with an exponential increase in population, triggering uncertainty over water resource.

With the pandemic added to the equation, water networks who are already suffering from a lack of investment are under even higher pressure with increased and variable demand profiles.

The solution? Adoption of integrated smart networks that comprises of intelligent equipment and data-driven digital solutions to support decision making. Artificial Intelligence (AI) is the key in this equipment to reduce time and effort in the monitoring and maintenance of these critical assets.

With smart networks installed, remote and continuous monitoring of operations and real-time reactive management and maintenance can be enabled. At the same time, digital solutions allow data-driven preventative adjustments to be made as part of the proactive management of systems.

One example is Yorkshire Water’s Hadfield smart water network pilot – a game-changing pilot project developed with significant investment from Yorkshire Water Services (YWS). The utility is running a proof of concept, smart networks pilot in Hadfield and Loxley over the next 12 months, with the aim to revolutionise their approach to leak management and supply interruption reduction.

This urban area, with a population of around 20,000, was selected as YWS has already deployed a wide range of sensors and meters (~3,800), including smart digital meters, acoustic and hydrophone loggers, temperature, pressure and water quality sensors.

Data visibility 

Xylem has deployed 1,500 of its Sensus-branded non-household smart meters connected via its FlexNet communication network. Using Arqiva’s dedicated private spectrum for Yorkshire Water, avoids the susceptibility and interference of sharing the spectrum with other users and applications, whilst uniquely and reliably providing coverage to meters in hard-to-reach locations such as deeper parts of buildings and meter pits.

The Hadfield smart water network pilot is a multi-stakeholder collaboration, with over 15 vendors, Xylem’s data monitoring and analytics platform, View was selected to improve data visibility and provide critical insights.

Xylem’s ViewTM platform will:

The disruptive and innovative pilot will present rich data from new and existing sources in an integrated, single visualisation platform. The platform uses machine learning and AI to cluster data sets and remove false positives to accurately inform asset and operational decision making.

The analytics system will use historical data to understand the signals that precede incidents, such as pressure transients in the pipe. Where transients in the network are identified, YWS can use this data to identify the source. Once completed, a review of the network operation would be conducted to avoid any future issues and to help YWS optimise processes, extend asset life and even inform infrastructure planning; key competencies for strengthening resilience in the round.

The cloud-based system will help meet YWS Outcome Delivery Incentives (ODI’s) mainly leakage, per capita consumption (PCC), supply interruptions, customer measure of experience (C-MeX) and bursts per km, together with vision and values. YWS have developed a framework for assessing the success of the pilot, covering aspects from telecommunications and accuracy of data, through to the performance of the platform to display data and provide analytics, through to meeting the ODI’s put in place by Ofwat for AMP7.

Proactive utilities across the globe are benefiting from such smart water solutions:

Being smart with water

Scalable, smart network solutions can be customised to different customer needs. Modular solutions allow utilities to select the functions they need to tackle the problems they are facing, whilst being scalable to meet the changing needs over time. Leakage management teams can benefit from their existing data sources whilst enriching with newer data sources to allow deeper insights to be drawn by layer data for more context.

Key benefits of adopting smart water solutions:

Provide an improved, proactive service to customers, by mitigating potential interruptions before customer is impacted

Improve overall business performance by using data to provide actionable intelligence.

Disruptive, forward-thinking utilities, such as YWS, understand the true value and cost benefit of piloting such smart technology.
