News – News & UpdatesWater Breakthrough Challenge
March 22, 2022
Today, on World Water Day, we’re pleased to announce the 13 winners of the Catalyst stream of Ofwat’s second Water Breakthrough Challenge.
Ofwat has awarded £5.2 million to innovative, water company-led projects using new technology and cross-sector collaborations to improve water quality, reduce pollution, and enhance services for customers.
Between now and the summer, the Water Breakthrough Challenge will award up to £39m to projects across England and Wales. The Water Breakthrough Challenge is part of a series of competitions from Ofwat, and run by Nesta Challenges with Arup and Isle Utilities, designed to drive innovation and collaboration in the sector to benefit individuals, society and the environment.
13 projects will benefit from the first tranche of awards announced today, known as the “Catalyst Stream”. Read on, or you can find their full descriptions below:
Several innovations to improve water quality have been awarded prizes. Severn Trent, working with California-based Microvi Biotechnologies and Cranfield University, has been awarded £760,000 to begin work on a “biocatalyst solution” that uses microorganisms that remove ammonia from wastewater without generating nitrous oxide emissions (a gas 300 times more potent than CO2).
“Tapwater Forensics” from a consortium of seven water companies and the Centre for Ecology and Hydrology has been awarded £370,000 to meet its aim of establishing the UK as a leader in genetic sequencing of drinking water to revolutionise the ability to monitor and investigate water quality failures in the same way DNA testing revolutionised medicine and scientific research.
And £446,000 has been awarded to “SuPR Loofah” by Northumbrian Water, Welsh Water, the University of Newcastle and the University of Northumbria. The project removes and recovers phosphorous run-off from agricultural fertilisers using engineered micro-algae. This prevents it causing damaging algal blooms and uncontrolled outbreaks of weeds in watercourses which can suffocate natural ecosystems. Phosphorous is an essential but finite energy-intensive chemical resource which is diminishing – this new circular approach would see it re-used as fertiliser in agriculture. It can also reduce imports of phosphorus for farming and its associated emissions from mining and transportation.
It is great to see the water sector deliver more exciting and impactful projects through this round of Ofwat’s Water Breakthrough Challenge. The winners all have huge potential to benefit people, society and the natural environment. I’m excited to see these projects become reality and start to make a real difference in the way we do things.
In addition, projects that could contribute to preventing leaks from water pipes and sewers, and keeping associated repair costs down, have received £400,000. Yorkshire Water’s “Designer Liner” which can be retrofitted into existing water pipes, prevents leaks and extends the life of national water infrastructure. It in turn reduces the amount of water abstracted (i.e. removed) from watercourses which should also cut energy usage and costs to customers.
Meanwhile, “Pipebots” from Thames Water, the University of Sheffield and Synthotech Ltd are robots that can monitor sewer rising mains from the inside. Too often, rising main faults only come to light should they burst. The robot monitors enable preventative inspections while the pipe is in use to minimise the risk of pollution spills by identifying faults before a pipe ever fails.
It’s a pivotal moment for the water sector – meeting the challenges of climate change head on and making good on promises of improved water quality across the water system at pace. There is no silver bullet to fix these challenges – they all require multiple approaches and solutions like those awarded funding today.
The second Water Breakthrough Challenge is a £39 million competition, which aims to bring forward industry-leading innovation that deliver benefits for water customers, society, and the environment, split into two streams, the £5.2m Catalyst Stream and the Transform Stream which will award up to £34m.
The winners of the Transform Stream will be announced later in the Spring, and the winners of both streams will be showcased at a free online event on 10 May 2022. Register your place today.
The next round of the Water Breakthrough Challenge will open in Autumn 2022. Ofwat will be consulting on changes to this and future competitions soon – sign up to our newsletter to hear the latest news.
A HERU for Screenings– Led by Severn Trent – £198,144
The Home Energy Recovery Unit (HERU) is a waste recovery system developed to manage domestic and commercial waste on site. About the size of a chest freezer, this solution uses heat pipe technology developed from satellites, to turn screenings into energy, that can be recycled. It’s an innovative solution to a growing and challenging waste problem for the UK water industry.
Catalysing a NET-ZERO future – Led by Severn Trent – £762,447
One of the biggest sources of greenhouse gas emissions (GHGs) from the water industry is nitrous oxide – 300 times more potent than carbon dioxide. It’s produced by bacteria that plays a vital role in removing toxic ammonia from wastewater. If ammonia isn’t removed, it damages aquatic life. Recently researchers have identified naturally occurring bacteria that can remove ammonia without producing nitrous oxide but these don’t ordinarily thrive in treatment plants. This project will develop innovative techniques for capturing these game-changing bacteria and putting them to work in our existing treatment processes.
Defusing the nitrate timebomb – Led by Portsmouth Water – £154,800
Nitrate pollution has long been a threat to Chalk drinking water and dependent environments in Southern England. To reduce nitrate in drinking water requires expensive treatment or changes in farming practice. Water companies work with farmers to reduce nitrate inputs, but lack detailed knowledge of where to focus efforts for efficient, rapid results. The project will develop modelling software that can predict concentrations throughout the Chalk so that land use options can be tested to select those that deliver efficient nitrate reduction. This will reduce treatment costs and energy consumption and help to protect habitats and biodiversity.
Designer Liner – Led by Yorkshire Water – £173,880
Pipe lining is 50% cheaper than the more traditional method of digging up and replacing broken pipes. It also generates less carbon and is less disruptive for customers because there’s no need to dig up the road. There’s a gap in the current market to provide a lining solution fit for a 21st century water network. Water companies, led by Yorkshire Water, will collaborate to create a lining solution for clean water pipes with a much longer lifespan than existing linings and with the potential to include other technologies too. This will make water networks more resilient for the future and equip them to become smarter than ever before.
Pipebots for rising mains – Led by Thames Water – £230,930
Rising mains are sewage pipes which are pressurised so sewage can be pumped up hills to be treated at sewage works. It is difficult to survey these pipes because they are hard to access and to shut off so they can be inspected internally. Using robots on rising mains will help the industry spot, predict and fix pipes which are deteriorating before they burst preventing pollutions to the environment. This project will test the use of robots to assess the internal condition of these types of pipes to radically change the way how the industry takes care of this type of infrastructure. The water industry already uses human-controlled robots to assess its partially filled sewer tunnels and sewers which use gravity to move sewage. This project will pave the way for the autonomous robotics technology to be used in fully pressurised sewer pipes.
Support For All – Led by Northumbrian Water – £632,270
“Support for All” will involve designing, building and delivering a hub to securely host data on customers in vulnerable circumstances – when submitted once, the data can then be shared with other relevant utilities. Each utility company has Priority Services Registers of customers requiring additional support, and customers must currently register with each utility separately – inaccurate data means additional support isn’t always offered. The new solution allows customers to ‘tell us once’, informing all relevant utility companies of the support they need. The aim is to develop a pilot of a working model, implement this at a regional level and then scale nationally.
SuPR Loofah (Sustainable Phosphorus Recovery) – Led by Northumbrian Water – £445,577
Northumbrian Water, with Northumbria University, the University of Newcastle, and Welsh Water will trial the use of an innovative loofah to remove and recover phosphorous from wastewater. This prevents it from causing damaging algal blooms, which can suffocate local ecosystems. This innovative ‘SuPR Loofah’ treatment system will place micro-algae on a loofah material, and use this to capture phosphorous from wastewater. As well as being a more affordable and sustainable process to wastewater treatment, this world-leading circular approach will generate a vital form of phosphorous which can be used as fertiliser.
Tap Water Forensics – Led by Severn Trent – £371,215
Our project will develop the use of genetic sequencing in drinking water treatment. Unlike current tests, genetic sequencing can determine all the bacterial species present in water. This will significantly improve the speed and accuracy of water quality investigations. We hope customers in England and Wales will benefit from a £3-5m/year reduction in bills, enabled by improve efficiency in water quality investigations; as well as a reduction in unplanned remedial work and disruption to supplies.
Sub-Seasonal Forecasting to Improve Operational Decision Making – Led by Thames Water – £678,750
This project will create a reliable weather impact modelling and forecasting system which will help water companies forecast weather events beyond 10-14 days, up to 4-6 weeks ahead. These systems will improve water companies’ understanding of how the weather impacts their water and wastewater management. Using these systems will improve their resourcing and operational management capabilities for areas at risk from severe weather events, for example, rapid changes in customer demand for water and regions which are prone to surface water flooding.
Incentivising community-centric rainwater management – Led by Thames Water – £225,000
Thames Water has partnered with Anglian Water, South West Water, Indepen, Isle Utilities and Our Rainwater to encourage communities in their regions to adopt rainwater capture tools and solutions, to help prevent rainwater from entering the sewer network. When it rains heavily, excess water runs off people’s homes and driveways and enters the sewer network which can contribute to the network being overwhelmed and lead to surface water flooding, sewer flooding and sewage discharges. The project will encourage the widespread adoption of rainwater capture methods at a grass roots level. It will test and measure how communities can be incentivised to take up these measures and help protect the environment.
Unlocking bioresource market growth using a collaborative decision support tool – led by Anglian Water – £314,316
Anglian Water will work with four water companies to develop a collaborative strategic planning capability, underpinned by Business Modelling Associates’ adaptive systems planning software. This will identify opportunities to trade bioresources across existing assets and determine the optimal blend of future inter-company investments; tackling common challenges and maximising environmental and customer value.
Unlocking digital twins – Led by Thames Water – £334,800
A ‘digital twin’ is a virtual representation of a water company’s physical assets or processes, for example a digital version of its pipe network and water treatment process. Water companies use these digital twins to unlock new data-driven innovations, which can improve their services and how they manage their networks for the benefit of customers. More companies are using digital twins but there is no agreed standard model and process for creating them, which has the potential to create inefficiencies, reduce the value delivered by these systems and increase costs. This project will create standards to support consistent digital twins throughout the industry.
Water Quality As-A-Service Treatment-2-Tap – Led by Northumbrian Water – £714,880
Treatment-to-Tap will demonstrate a step-change in the management of the water quality (WQ) for customers. By the end of the project, Northumbrian Water will be operating Europe’s largest integrated network of WQ and leakage management sensors and analytics software. Managing WQ is an increasing challenge due to ageing networks serving a growing population. This new behavioural science research will assess how best to engage and support customers when real-time WQ insight is available – meaning water company operations will be more intimately connected to customers than ever. A consortium of five water companies will all input to define and validate best practice on how new insights can be built into proactive operations. A new business model template will then enable all water companies to see how they can share risk and scope with the supply chain to deliver at scale and pace for least cost and best service to the customer.
