Dirty Business: Sewage, Lies & UK Water Crisis Explained

Channel 4’s new documentary series, Dirty Business, isn’t just sparking conversation – it’s igniting a full-blown debate about the privatization of Britain’s water industry. Directed by Joseph Bullman, the series lays bare a shocking reality: water companies are collectively dumping sewage into rivers and seas around 1,600 times a day. But the outrage doesn’t stop there. Despite each incident being a punishable offense with up to five years in prison, not a single executive or board member has ever faced prosecution.

Bullman, speaking to Radio Times, describes the situation as a “35-year train-wreck of water privatisation.” The series, which has already garnered attention with a particularly resonant tweet from a viewer tracking sewage dumps from a Thames Water facility, isn’t shying away from naming names and detailing the systemic failures that allow this to continue.

A ‘Potemkin Regulator’

The core of the problem, as highlighted in Dirty Business, lies with the Environment Agency, the body responsible for regulating the water companies. A whistleblower within the agency, Chanel Cresswell’s character (based on real-life Robert Forrester, who came forward after years of legal battles), describes it as a “Potemkin regulator” – a facade of oversight that lacks genuine enforcement power. The term, Bullman explains, originates from a story about Russian Field Marshall Potemkin constructing fake villages to impress Empress Katharine during a visit.

This lack of enforcement isn’t accidental. According to the documentary, policies implemented by the Agency actively hindered investigations. “Operator self monitoring” allowed water companies to essentially police themselves, while a climate change initiative resulted in investigators losing access to vehicles, making it nearly impossible to reach sites for inspection.

The Story Behind the Investigation

The making of Dirty Business was a two-year undertaking for Bullman and factual producer Laura McCutcheon. McCutcheon’s research uncovered a crucial source: a man using the pseudonym “Dave” (later revealed to be Robert Forrester) who provided internal Environment Agency documents detailing these problematic policies. The team meticulously verified the information, building a case based on inquest documentation, trial transcripts, internal memos, and correspondence between investigators, water companies, and the Agency. As Bullman notes, every line of the script is “underpinned with a corresponding evidential source.”

The series also features the stories of individuals directly impacted by the pollution. Heather Preen, who died after contact with sewage-contaminated water in 1999, is a central figure, with the documentary working closely with her mother, Julie, and the founder of Surfers Against Sewage, Chris Hines. Another case highlighted is that of Reuben Santer, a surfer who developed Meniere’s disease, a condition doctors believe may be linked to exposure to sewage. The emotional weight of these stories is amplified by the fact that actors were “traumatised” by re-enacting the experiences of real people affected by the pollution, leading to a collective “verbal group hug” at the end of filming.

Balancing Tragedy with Dark Humor

Bullman faced a unique challenge in portraying the situation: the sheer absurdity of the water companies’ justifications and the Agency’s policies. He ultimately decided to lean into dark humor, casting comedic actors like Alice Lowe (known for Prevenge), Charlotte Ritchie (Fresh Meat), and Asim Chaudhry (People Just Do Nothing) to portray the figures within the water companies and the Agency. “Is that bad? Or just the way life is?” Bullman asks, acknowledging the delicate balance between acknowledging the tragedy and highlighting the farcical nature of the situation.

What’s Next?

The documentary’s revelations have fueled calls for systemic change. Green Party leader Zack Polanski is advocating for a return to collective ownership of the water companies, a move that would fundamentally alter the landscape of the UK’s water industry. The immediate demand, however, is for criminal prosecutions. Bullman believes that holding water company executives and board members accountable is crucial to ending the ongoing pollution. The series concludes by naming Robert Forrester, the whistleblower, as a “national hero,” a testament to the courage it took to expose the truth. The ongoing public reaction and political debate suggest that Dirty Business has successfully initiated a critical conversation about the future of water in Britain. Further discussion and analysis of the issues raised can be found in The Guardian and Radio Times.

The series is available to stream on Channel 4. ELLE provides further background on the making of the documentary and its comparison to the Mr Bates Vs The Post Office scandal.
