Anglian Water's @one Alliance
Trialing mycofiltration to break down contaminants commonly found in surface water runoff
Anglian Water’s @one Alliance's Joshua Mercer’s Innovative Mycofiltration Work Secures Ofwat Funding to Help Shape the Future of Water Treatment
The Anglian Water @one Alliance is proud to see the outstanding work of Innovation Project Manager Joshua Mercer recognised following the successful award of £1.7 million funding through Ofwat’s sixth Water Breakthrough Challenge.
Joshua has been playing a leading role in driving forward Anglian Water’s innovative mycofiltration project, which is an exciting nature-based solution that uses mycelium, the root-like structure of fungi, to help remove pollutants from river water in a low-carbon and sustainable way.
Led by Anglian Water Services and supported by a wide range of partners from across industry and academia, the project has secured funding through the Water Innovation Fund to trial mycelium-based filtration systems at storm overflows and run-off sites.
The trials will explore how mycofiltration can naturally break down pollutants including hydrocarbons, E.coli, phosphorus, nitrates and other contaminants commonly found in surface water runoff. Which in turn help’s improve river health while also supporting more sustainable approaches to water treatment.

Joshua’s passion for innovation and environmental improvement has been instrumental in helping bring this project to life. Through collaboration with partners, suppliers and researchers across the sector, he has continued championing the potential of mycofiltration and the role it could play in helping shape the future of water management.
This exciting initiative brings together a fantastic network of partners including Barhale Ltd, Imperial College London, Scottish Water, South East Water, South West Water and University of Essex.
And more recently, Joshua has also been working closely with leading academic institutions to help further develop the research and collaboration behind the project. Alongside David Singerton from Anglian Water Services’ Innovation team, he visited Cranfield University and the Magan Centre of Applied Mycology to connect with experts including Dr Aman Thakur and Professor Roberto Parra-Saldivar.

These ongoing collaborations are helping unlock new ideas and opportunities, including discussions around future research projects and a fully funded PhD opportunity focused on advancing mycofiltration technologies even further.
Work is already underway at South Benfleet, where mycofiltration sacks have been installed into a newly constructed Mycelium Wetland alongside Anglian Water Services, Catchment to Coast and researchers from the University of Essex. The pilot site forms part of a wider programme of trials taking place this year to better understand how fungi-based filtration systems could complement traditional treatment methods in the future.

And the Anglian Water @one Alliance are always exploring new ways to work with nature and embrace innovation to tackle some of the biggest environmental challenges facing the water sector. The success of this project is a brilliant example of how passionate individuals like Joshua Mercer, working collaboratively with partners across the industry, are helping drive positive environmental change and shape a more sustainable future for our communities and ecosystems.
