CaSTCo: Roadmap
for the Future

A vision for the future of unified catchment monitoring in England and Wales
Over the last four years, the Catchment Systems Thinking Co-operative (CaSTCo) project has demonstrated that it is possible to move from disparate, monitoring “campaigns” into continuous, unified stewardship of our water environments. This is all thanks to the efforts of partners and communities across the water and environment sectors, that have turned scattered measurements and data into coordinated intelligence.
The goal for this Roadmap is based on an ambitious vision: that by 2035 every river in England and Wales is monitored, understood and cared for through a single open data system that unites regulators, utilities, researchers, businesses and communities. The result – faster action on pollution and clearer accountability of the health of our river systems that are no longer managed in silos but as the blue threads that stitch together climate resilience, public health, biodiversity and local prosperity across the UK.
This vision unites utilities and regulators, aligning investment and seeking insight beyond the bounds of the requirements of existing regulations such as Section 82. NGOs, community groups and citizen scientists collectively share monitoring data and insight more widely, across the whole spectrum of catchment health considerations. Tech providers and researchers co-design solutions and tools that turn raw readings into rapid action and value and funders and philanthropists channel their funding to enable benefit and impact across multiple bottom-lines – economic, environmental and societal – to futureproof collaborative catchment monitoring for all.
Why does this matter now more than ever? In a real watershed moment for the water sector of England and Wales, the Independent Water Commission (IWC) has made it clear that fragmented data, weak accountability and low public involvement are holding back river health improvements. The Roadmap, co-designed by the CaSTCo project and its Taskforce, responds with a practical, fast-forward plan to fix the gaps we are experiencing, turning pilots and demonstrators into a national system that supports better policy, smarter regulation and healthier rivers.

Four shifts
We are not proposing short-term fixes or small tweaks; the Roadmap is about rewriting how river monitoring works, shifting from:
Fragmentation to integration
One standard, open, shared data system, underpinned by unified action and governance, allowing different stakeholders to access and contribute to the same reliable information, reducing fragmentation and improving coordination.
Data collection to decision-making
Moving beyond data accumulation and “monitoring for the sake of monitoring”. This is about promoting a “weight of evidence” approach, so that data collected from a wide range of sources can become trusted information that drives targeted actions.
Short-term remedies to long-term resilience
Diversified funding and governance that enable an integrated monitoring approach, including citizen science, to be planned and sustainably delivered, not only for months, but for decades to come.
Public distrust to public engagement
Accredited citizen science, transparent data and local storytelling that rebuild trust and empower communities and stakeholders.
