Water Breakthrough Challenge 1

The water industry is heavily dependent on the use of metal-based coagulants for the removal of phosphorus on rural wastewater treatment plants. The fragility of this approach has been highlighted as recently as September 2021 when the BBC reported on the need for the Environment Agency to allow reductions in chemical use to address lorry driver shortages. The sector needs more sustainable solutions if it is to maintain water quality within our watercourses and reduce our carbon footprints.

United Utilities will lead a project providing a holistic view of what can be achieved using alternative phosphorus removal approaches. The UK water industry spends in the region of £39M/year on metal coagulants. Finding a suitable alternative would reduce this and the carbon associated with the manufacture and delivery of these chemicals.

Lisa Mansell – United Utilities, Chief Engineer Innovation said: “Securing funding for this project is a great achievement. It will significantly advance the adoption of alternative options for phosphorus removal from wastewaters. These options aim to reduce the cost of delivering environmental improvements (savings that could drive down customer bills), but could also significantly reduce our carbon footprint.”

A cross-sector coalition, led by Seven Trent Water – with partners including Microsoft, BT, the National Cyber Security Centre and the University of Exeter – to pilot the use of artificial intelligence that monitors a waste catchment area in real time to minimise the risk of flooding and sewage pollution. With the water industry accounting for 35% of river pollution, the project has received around £2 million to develop new and integrated approaches for spill prevention.

Rich Walwyn – Head of Asset Intelligence & Innovation – Severn Trent Water, said: “This provides a brilliant opportunity for a ground-breaking collaboration with our water company partners and global innovators to deliver benefits for our customers and our environment. By leveraging the power of the internet of things, artificial intelligence, and machine learning, we will be able to maximise the use of the available capacity in our network to reduce floodings and storm overflows as well as optimising our treatment works to reduce our carbon footprint.”

Catchment Systems Thinking Cooperative (CaSTCo) – a partnership led by United Utilities between the Rivers Trust, twelve water and sewerage companies as well as academia and environmental charities– has been awarded £7.1 million to revolutionise the way crucial data about England and Wales’ water environment is gathered and shared, in particular on the health of the nation’s rivers. Only 14% of rivers in England are in ‘good health’ – one of the worst records in Europe. This project will ensure there is robust evidence base for tackling environmental challenges with direct support for local evidence gathering and community engagement in eight demonstration catchments, and a national framework of standardised tools and training.

Michelle Walker at the National Rivers Trust said: “This is a revolutionary new approach to the way we gather and use evidence to drive collective action and make decisions about the water environment. Thousands of trained and resourced citizen scientists and local communities will work with different partners to carry out monitoring and collection of high-density data, complemented by a network of sensors and hi-tech monitoring. This wealth of information will be gathered and shared into a central visualisation platform, helping us all to be part of decisions to invest in the right priorities, to give the biggest improvement to the state of our rivers.”

Bristol Water, in partnership with Binnies, RWE, Castle Water and The University West of England has been awarded over £620,000 to pilot a novel solution to drought planning while reinventing the water retail market as we know it. The first of its kind project will pilot the design of localised third-party water supply and treatment, seeking to overcome current market blockers. The project could deliver huge benefits for drought resistance and put more freedom into the hands of water retailers to incentivise business customers to save water.

Project partners: Bristol Water, Binnies, RWE, Castle Water, University of the West of England.

Mel Karam, CEO of Bristol Water, said: “The industry needs an estimated £21billion to build resilience to drought over the next 30 years. To complement the industry’s focus on infrastructure to pump water further, with our partners we’re exploring the development of localised third party treated water supplies”.

John Reynolds, CEO of Castle Water, said: “These third party treated water supplies could reinvent the retail and wholesale market as we know it today, fit with our low carbon future and provide much-needed incentives for a step change in business water efficiency.”

Anglian Water and its partners Jacobs, Skanska, Imperial College, Airbus Defence and Space, Microsoft and the University of Sheffield, and fellow water companies South West Water, Portsmouth Water and Affinity Water, have been awarded £7.5 million for their Safe Smart Systems project. The project will use artificial intelligence and mathematical optimisation to improve long-term operational resilience in the face of climate change and rapid population growth. It will identify, predict, and manage vulnerabilities to reduce leakage, interruptions, and pressure issues across the whole water cycle. Safe Smart Systems focuses on the first steps to achieve autonomous control in water systems across the UK.

This project will deliver a sustainable, water-saving solution in response to new housing developments being built. Winning £2.9 million, it will minimise water demand and offset water consumption with new technologies, to ensure the total water use in the community remains the same as it was before the new homes were built.

Affinity Water and its partners will do this by installing water saving devices in customers’ homes – such as shower heads, tap inserts and larger equipment that recycle washing machine water or collect rainwater. This will mean customers use less in their homes. The project team will also install larger technologies on commercial buildings like schools and leisure centres – for example greywater recycling and ultra-low flush toilets. By combining the reductions from customers and commercial building the total amount of water used within the area will remain the same.

Affinity Water has partnered with three different NAV sites (smaller water companies that manage new build housing developments). This will allow to trial different approaches and see which options work best, as well as helping smaller companies break into the market. Customers will have lower bills, water companies will be able to trial water neutrality at scale and the smaller water providers (NAVs) will benefit from better access to the market and strengthened industry partnerships.

Project partners: Affinity Water, Albion Water Limited, Aquality Trading & Consulting Ltd, BUUK Infrastructure UK No 2 Ltd, Grapviners Ltd, H2OiQ Ltd, Hydraloop International, Propelair – Phoenix Product Development Ltd,  SDS Ltd, Skewb.

Stuart Ledger, Interim CEO Affinity Water, said: “We need water neutrality to be delivered in the UK. Sustainable growth is essential given the ongoing impact of climate change and our pledge to net zero operational emissions by 2030. Thanks to Ofwat’s Water Breakthrough Challenge, we will kick start the launch of water neutrality in the UK with the world’s first at scale project. Our partnership of industry leading providers will install water reduction and recycling technologies and engage communities to ensure water savings, carbon reductions and support NAV partnerships.”
