If you caught the news this morning, you might have been nudged into believing we have turned a corner on the sewage crisis. The headlines trumpet a 35% reduction in spills, packaged as the prize of record investment.
It is a sham.
Let’s be blunt: the main reason sewage spills reportedly "fell" to around 300,000 incidents last year is that it stopped raining. The UK saw the driest spring in a century and the hottest year on record.
You can’t have "storm overflows" if there aren’t any storms.
To sell a drought as an environmental triumph is corporate gaslighting — and it ought to anger every bill payer who is being asked to bankroll the story.
You can’t rebrand dry weather as virtue. It is not proof that the sewage system is fixed.
The maths of a rigged game
The industry line
The sector is congratulating itself for "only" dumping raw sewage for 1.8 million hours while households were under hosepipe bans.
The reality
Even in a drought year, that is roughly one million more hours of pollution than in 2018. This is not a clean bill of health. It is a slower leak from a system that is still bleeding into rivers and coasts.
The insult
While companies imply this "improvement" justifies a 36% bill hike, many catchments are still being used as all-weather waste pipes because the underlying infrastructure has been under-invested in for decades. The PR gloss does not change the physics: too much flow, too little capacity, too many shortcuts.
When it’s dry, spills can be even more serious
Discharges during drought conditions are not a footnote. When river levels are low, anything entering the channel is less diluted — so the same volume of pollution packs a harder punch for wildlife and for anyone downstream: swimmers, anglers, and communities included.
If you are spilling sewage during a drought, those spills are not just "unfortunate" — they are illegal.

2026: the reckoning after the dry year
The upbeat tone of today’s narrative is especially jarring set against what many people are seeing on the ground in 2026. We are only a few months in, and the "it was a dry year" excuse is already threadbare.
Official Environment Agency figures for the full year will take time to audit, but early signals from January and February 2026 suggest they will be one of the heaviest spills for the first two months of the recent years.
When the rain returns, the spreadsheets stop flattering you. That is when you learn whether anything real was built — or whether the “gain” was mostly meteorology.
This is not progress
Calling this a "positive story" because the sewage spill hours moved in a drought is at best naive; at worst it is knowingly misleading.
Ministers may say it is "good to see" any downward move. For anyone who uses rivers and the sea, the more honest question is simple: is the water cleaner where I launch? Are spills lawful, rare, and fully explained? A hot, dry year can hide pressure points. It does not fix them.
The scale still shames
Even in these conditions, the numbers remain obscene:
- South West Water: on the order of 407,000 hours of reported sewage dumping.
- United Utilities: around 327,000 hours.
- Thames Water: while carrying something like £17.6 billion of debt, still behaves as if waterways are an open sewer — a reminder that balance-sheet drama and river health are not the same problem, even if they share a logo.
To spin this as victory is an insult to every swimmer, fisher, and resident who has watched a local river turn the colour of cement and carry a stench through the summer.
They did not fix the pipes. The sun briefly dried up the evidence — and the headlines mistook weather for ethics.
2026 is already reminding us: when it rains, they pour — and bill payers are left funding the performance.
