Episode 75: The River of Truth with Ash Smith

Episode 75:
The River of Truth

Guest: Ash Smith

Hosted by: Marina Robb

Ash Smith

In this episode, I’m speaking with Ash Smith, the founder of Windrush Against Sewage Pollution. A retired Detective Superintendent, former angler and scuba diver, Ash has spent the last eight years investigating the truth about what’s happening in our rivers. His love for the natural world, combined with a deep sense of justice, led him to gather a team of committed people from different disciplines to form one of the most effective groups holding water companies and regulators to account.

In our conversation, Ash shares what’s really going on with our rivers, the scale of sewage pollution, and the failures of government and regulatory bodies to protect our waterways. This is a passionate, evidence-based discussion, grounded in data that you can find on the WASP website. The Windrush itself flows for 65 kilometers from Gloucestershire into the Thames - but this story reaches far beyond one river. It speaks to the health of our ecosystems, and to our own health as well.

What happens when those who are meant to protect our rivers become part of the problem? In this gripping conversation, Marina speaks with Ash Smith, founder of WASP (Windrush Against Sewage Pollution) - a grassroots group of scientists, anglers, and citizens uncovering the truth about what’s flowing through the UK’s waterways. From hidden data to public accountability, this episode reveals how courage, evidence, and persistence can challenge corruption and restore hope for our rivers.

A vivid picture of what a living, healthy river once was — and how the “new normal” hides a quiet collapse.
How WASP (Windrush Against Sewage Pollution) turns citizen science and data analysis into undeniable proof of illegal pollution.
The shocking reality of regulators who no longer investigate — and water companies marking their own homework.
What happens when public services are sold off and profit replaces purpose.
The money trail — how customers fund dividends while private shareholders drain the system.
Why some water companies are now in “special measures” and what real accountability could look like
Ash’s journey from detective superintendent to river defender — following the evidence wherever it leads.
The quiet power of ordinary people who refuse to look away.
How anger can become fuel for change rather than despair.
Practical ways to take action — join with others, use local data, and make enough noise to tip the balance
