Britain’s sewage crisis is poisoning its waterways and economy

Widespread sewage spills are contaminating Britain’s waters, threatening businesses, biodiversity, and public health, while weak regulations and corporate profits take priority over investment in critical infrastructure.

Kate Holton and Dylan Martinez report for Reuters.

In short:

  • Britain’s largest offshore mussel farm, located to avoid sewage pollution, is still plagued by harmful bacteria like E. coli, blocking exports to Europe and damaging the shellfish industry.
  • Water companies discharged sewage for 3.6 million hours in 2023, contaminating rivers and coastlines, harming tourism, and forcing the government to review the sector. Privatized firms, which have paid billions in dividends, are accused of neglecting infrastructure upgrades.
  • Activists and clean water advocates are fighting back, linking sewage failures to stalled construction projects, biodiversity collapse, and public health risks, forcing officials to confront decades of underinvestment and weak oversight.

Key quote:

“It’s criminal that they’re allowed to dump what they dump in the seas and get away with it. It's affecting all sorts of businesses, including us.

— Sarah Holmyard, sales manager at Offshore Shellfish

Why this matters:

As climate change intensifies rainfall, Britain’s crumbling infrastructure is reaching a breaking point. Regulators, long accused of looking the other way, are under mounting pressure as activists connect the dots between failing water infrastructure, stalled housing projects, and collapsing ecosystems.
