Scottish Liberal Democrat environment spokesperson Sanne Dijkstra-Downie has today written to the Cabinet Secretary Gillian Martin demanding that the SNP start taking the sewage crisis seriously as new Scottish Water monitoring revealed that sewage discharges last year were four times as high as previously recorded.
This comes after Scottish Water published data from 1,009 newly installed sewage overflow monitors, which means annual monitoring data is now available for 30% of sites, compared to 6% in previous years.
Figures published by the government-owned water company earlier this week show that in 2025 alone:
- 100,041 discharges were logged, up from 24,398 incidents in 2024 – a new record
- Sewage was dumped for a total of 276,755 hours in 2025
- That equates to more than 758 hours of sewage dumping a day.
Scottish Liberal Democrat environment spokesperson Sanne Dijkstra-Downie said:
These figures are a real horror show.
Sewage dumping is four times as high as we thought it was last year. This shows the Scottish Liberal Democrats were right to call for expanded monitoring and exposes how naive SNP ministers have been.
This is the equivalent of 274 dumps taking place every single day.
Yet even that number is likely an underestimate of the true scale of the problem. Even with these extra monitors Scotland is still way behind England where 100% of sewage overflows are monitored.
To make matters worse, the government owned water company is paying out bumper bonuses to its executives while sewage is being dumped into our rivers, lochs and beaches more than 100,000 times in 2025.
The Scottish Government needs to start listening and taking this crisis seriously.
Scottish Liberal Democrats have a plan to get to the bottom of this filthy practice. That means a Clean Water Act to take the sewage scandal seriously, track down and report every sewage dump, and replace outdated standards with modern enforceable regulation.

Interesting given how often we have been told that Scottish water shows the benefits of public ownership to see that when comparable measures are taken there is much less differnce
@ Simon McGrath I’m sorry but I’m afraid your comment owes more to opinion than to fact, Simon. Some comparable facts :
“The Independent Water Commission, led by Sir Jon Cunliffe, found many more of Scotland’s water bodies are of good ecological status than England or Wales:
66% in Scotland are of good ecological status
29.9% in Wales
16.1% in England
Water Charges also diverge :
The average annual charge in Scotland this year is around £450.
In England, it’s over £600,
In London, around £640.”
I’d add that the taste of water from my tap in Scotland is far better than water from the tap in London.
Simon McGrath 7th Sep ’26 – 5:13pm.. shows the benefits of public ownership to see that when comparable measures are taken there is much less differnce…
The difference is that Scottish water is not completely worthless due to asset stripping as in the English in water companies, where their private owners have extracted massive financial dividends and loaded the business with heavy debt instead of investing in essential infrastructure…
“66% in Scotland are of good ecological status
29.9% in Wales
16.1% in England”
Might this have something to do with the fact that most bodies of water in Scotland have no significant human population upstream?
