As its pilot year concludes, English and Welsh water regulator Ofwat has launched a consultation about its £200 million Water Innovation Fund.

Ofwat is seeking the views from a wide range of sectors, including the UK’s space, fintech, digital, agricultural, academic and manufacturing sectors about the future of the fund and how it can better engage innovative companies outside of the water sector in its multi-million Water Breakthrough Challenges.
Following a year-long pilot that has seen more than £43 million awarded to cutting-edge innovation in the water sector, Ofwat has launched a new consultation to seek views about how to continue the momentum.
The £200 million Water Innovation Fund – designed to drive long-lasting change and innovation in the sector – has already generated multi-sector partnerships in response to a series of competitions – including the Innovation in Water Challenge and two Water Breakthrough Challenges.
The competitions were run by Nesta Challenges – in partnership with Arup and Isle Utilities – and have generated innovative solutions from water companies and their partners to the challenges of net zero, environmental impact and improving consumer services.
Winners have included projects to generate green hydrogen from wastewater, partnerships to provide data on water quality to communities in an open and accessible way and novel engineering solutions to prevent pipes bursting, using everything from robots to ‘designer liners’ that can be retrofitted on the inside of water mains.
Ofwat is now proposing to run a third Water Breakthrough Challenge in Autumn 2022. It also proposes to run a fourth in 2023 and a fifth in either 2024 or 2025 with the potential to run competitions beyond 2025.
The water sector regulator is keen to hear from individuals, companies and representative bodies across academia, the construction sector, the UK’s space sector, the chemical and pharmaceuticals industry, the digital sector, agriculture and fisheries, the energy sector, marine sector, manufacturing and logistics, and the retail banking and fintech sectors.
Going forward, Ofwat wants to consider changes that will enable the fund to support more early-stage ideas in order to allow innovators to have greater access to the fund. The proposals include:
- Open a new annual £4 million competition for early-stage ideas from innovators either in or outside water. It will focus on enabling and supporting earlier stage idea development. The new competition will target primarily innovators and not require a partnership with a water company to enter.
- Maintain the annual flagship competition, with adjustments to some entry rules to encourage wider participation. It would maintain the Water Breakthrough Challenge with Catalyst and Transform streams for each competition during 2022-25. For Catalyst (entries between £250k and £1million) it would make about £6m available annually, not require a partnership with a water company to enter and allow background IP to be licensed. For Transform (entries between £1m-£10m) it would make about £30 million available annually and allow background IP to be licensed.
