Swimmer's Heart Surgery After Sewage Exposure
25 Feb
Summary
- A cold-water swimmer contracted a severe bacterial heart infection.
- She believes the infection resulted from swimming in sewage-polluted water.
- Her experience is featured in the Channel 4 drama 'Dirty Business'.

A woman's passion for cold-water swimming turned into a near-fatal health crisis, leading to open-heart surgery after contracting a bacterial infection. In January 2024, doctors discovered a bacterial infection in her heart, requiring surgery to save her life. She believes the bacteria entered her body while swimming in waters known for sewage pollution. Her experience, alongside whistleblowers, is now featured in the new three-part Channel 4 drama, 'Dirty Business.'
The drama chronicles a decade-long investigation into England's water companies, exposing a major corporate scandal. The woman, who previously ran a coaching business and enjoyed regular swims with friends, fell severely ill after a Boxing Day swim in late 2023. Symptoms included extreme exhaustion and breathing difficulties, leading to a diagnosis of endocarditis.
Despite initial antibiotic treatment, her condition worsened, necessitating emergency open-heart surgery. The infection has had a lasting impact, forcing her to halt her business and leading to a subsequent brain bleed likely caused by medication. She has since become an advocate, submitting a sickness report and starting a parliamentary petition calling for year-round water testing by water companies. She hopes her story in 'Dirty Business' will prompt greater responsibility from water companies.
