£7.7m initiative targets pollution at source in England’s overlooked headwaters
19th May 2026
A major £7.7 m initiative launched today will tackle water pollution and environmental decline by focusing on one of the most neglected parts of England’s river network: headwater streams, ponds and small wetlands.
The programme ‘Headstart: unlocking the value of headwater catchments’ has been named a winner in the sixth Water Breakthrough Challenge by Ofwat’s Water Innovation Fund.
Led by Anglian Water and Freshwater Habitats Trust in partnership with a wide range of environmental organisations, Headstart will develop practical ways to improve water quality and freshwater biodiversity by targeting problems upstream, in headwaters at the top of river systems.
Although headwaters make up most of the length of river networks, they are often weakly protected by regulation, and largely absent from national river assessments. As a result, they have not been prioritised for water industry investment. Yet these small streams and their associated ponds and wetlands play a critical role in supplying clean water, supporting wildlife and protecting downstream rivers, lakes and reservoirs.

The launch comes amid heightened public concern about river pollution and increasing recognition that current strategies focus too heavily on larger downstream waterbodies. overlooking damaging pollution higher-up in catchments.
It also precedes the introduction of the Clean Water Bill, which provides the biggest opportunity in a generation to reform our approach to water management.
By ‘starting at the top and working down’, the project aims to deliver fast improvements for both biodiversity and water quality, exploiting the potential of headwaters as areas where rapid improvements to the water environment can be made.
Measures implemented by Headstart will include improving small wastewater treatment works, which can badly pollute the small streams they often discharge into. The programme will also focus on restoring wetlands and ponds, creating cleaner, more resilient headwater habitats and working with farmers to reduce diffuse pollution before it can get into streams.
Headstart will initially focus on six demonstration catchments across England, working with six water companies: Anglian, Northumbrian, Southern, Thames, Wessex, and Yorkshire Water. The project will track changes in water quality, biodiversity and river flow to provide a blueprint for restoring headwaters across England and Wales, helping target investment where it can have the greatest impact.
By improving water quality closer to pollution sources, the programme aims to generate cumulative downstream benefits for rivers, lakes and drinking water supplies while also helping wildlife recover. Evidence from the demonstration sites will help the project prioritise changes that regulators should make to water policy.
Chris Gerrard, Head of Natural Environment at Anglian Water, said: “Through Headstart, we have an opportunity to take a more proactive approach by tackling potential pollution closer to source and working across different catchments to deliver critical environmental improvements. This programme will help build a stronger evidence base for how targeted action can create lasting benefits for wildlife and water resilience in the face of increasing environmental pressures.”
Professor Jeremy Biggs, CEO of Freshwater Habitats Trust said: “Headwaters are where many freshwater problems begin – but they are also where solutions can be most effective. If we want cleaner rivers downstream, we need to start upstream.
“These small waters are largely missing from policy, monitoring and investment, despite being critically important for biodiversity, clean water and climate resilience. Headstart is about changing that.”
Headstart follows increasing concern from environmental organisations that small waters remain invisible in regulatory frameworks, despite evidence that they support disproportionately high levels of freshwater biodiversity and strongly influence ecological conditions downstream.
The initiative will run workshops, field visits and collaborative events over the coming years, helping encouraging wider adoption of headwater-focused approaches nationally. The programme will also address gaps in national monitoring and evidence, helping build a stronger case for greater recognition of headwaters in river basin planning and water industry investment.

Jo Jolly, Director, Innovation, Ofwat, said: “The water sector is going through its biggest transformation in 30 years. We have to make sure these changes drive far better outcomes for society and the environment. Multiple urgent challenges must be solved. And, importantly, our mindset must change. So that’s our mission: bold, innovative solutions that take a long-term approach to the health of our vital water system and the impact of the water industry on environments and communities. This line-up of winners shows us just what can be achieved when we set our minds to it.”
The Water Breakthrough Challenge is delivered by innovation prize experts Challenge Works (part of Nesta), in partnership with Arup and Isle Utilities, and funded by Ofwat’s Water Innovation Fund.
The Water Innovation Fund is a key pillar in Ofwat’s mission to drive innovation that ensures the water sector is ready for the challenges of the future and results in better outcomes for customers and the environment.
