The death of Heather Preen: how an eight-year-old lost her life amid the UK sewage crisis

05:00 - 18 Feb 2026

In 1999, Heather Preen contracted E coli on the beach. Two weeks later she died. Now, as a new Channel 4 show dramatises the scandal, her mother, Julie Maughan, explains why she is still looking for someone to take responsibility

When Julie Maughan was invited to help with a factual drama that would focus on the illegal dumping of raw sewage by water companies, she had to think hard. In some ways, it felt 25 years too late. In 1999, Maughan’s eight-year-old daughter, Heather Preen, had contracted the pathogen E coli O157 on a Devon beach and died within a fortnight. Maughan’s marriage hadn’t survived the grief – she separated from Heather’s father, Mark Preen, a builder, who later took his own life. “I’ve always said it was like a bomb had gone off under our family,” says Maughan. “This little girl, just playing, doing her nutty stuff on an English beach. And that was the price.” Yet there had been no outrage, few questions raised and no clear answers. “Why weren’t people looking into this? It felt as if Heather didn’t matter. Over time, it felt as if she’d been forgotten.” All these years later, Maughan wasn’t sure if she could revisit it. “I didn’t know if I could go back into that world,” she says. “But I’m glad I have.”

The result, Dirty Business, a three-part Channel 4 factual drama, is aiming to spark the same anger over pollution that ITV’s Mr Bates Vs the Post Office did for the Horizon scandal. Jumping between timelines, using actors as well as “real people” and with actual footage of scummy rivers and beaches dotted with toilet paper, sanitary towels and dead fish, it shows how raw sewage dumps have become standard policy for England’s water companies. Jason Watkins and David Thewlis play “sewage sleuths” Peter Hammond and Ash Smith, Cotswolds neighbours who, over time, watched their local river turn from clear and teeming with nature to dense grey and devoid of life. Hammond is a retired professor of computational biology, Smith a retired detective, and together, they used hidden cameras, freedom of information requests and AI models to uncover sewage dumps on an industrial scale.
