Newly revealed figures have highlighted the scale of sewage pollution in Scotland, with 165 spills recorded at the Seafield sewage treatment works in Edinburgh last year. These spills resulted in partially treated sewage being discharged into the sea for a total of 890 hours, raising serious concerns about environmental protection and public health.
Managed by the French utility company Veolia under a Private Finance Initiative (PFI) agreement with Scottish Water, Seafield is one of nine sewage sites operating under similar contracts.
Across these facilities, more than 500 sewage overflows were reported in 2023, amounting to a total of 3,500 hours of discharge. Major spillages were also recorded at locations such as Newbridge, Blackburn, Whitburn, and East Calder.
Scottish Labour MSP for the Lothian Region, Foysol Choudhury, has called for urgent action to address the ageing infrastructure and improve oversight of sewage discharges.
MSP Choudhury said: “The scale of sewage pollution in Scotland is unacceptable. Communities across the country, including here in Edinburgh, deserve clean beaches, rivers, and waterways.
“The current system is failing, and this must change.”
Mr. Choudhury has seen the Seafield site become a source of concern for residents, particularly after the Scottish Environment Protection Agency (SEPA) issued a warning in July 2023 advising against swimming at Portobello Beach due to high bacteria levels.
In May 2024, residents were encouraged to report odour and noise issues from Seafield via the Leith Links Community Council’s online nuisance report form to ensure complaints are sent directly to elected officials, including MSPs and councillors, to keep the pressure on to address these longstanding problems.
Choudhury said: “The Seafield Sewage Treatment Works has exposed local Leithers to a series of appalling odour and sewage leaks. What impact does this have on the local environment like the Water of Leith and the Forth?”
“Scotland’s beaches and waterways are among our most cherished natural assets. It’s not enough for operators to claim compliance with licenses— people deserve transparency and action to safeguard our environment and health.”
ACCOUNTABILITY FOR PFI CONTRACTS
The Seafield plant and others like it are managed under PFI contracts, but MSP Choudhury has questioned whether this model delivers for communities. In the Highlands, a PFI sewage plant has already been brought back under public control following the expiration of its contract.
Foysul Choudhury continues to raise questions and engage with local communities to demand greater accountability from operators and stronger action from the Scottish Government when it comes to polluting Scotland’s waterways.
LOOKING AHEAD
The PFI contract for Seafield is due to expire in 2029, at which point the plant will revert to public control under Scottish Water. Mr. Choudhury hopes that this transition is used as an opportunity to overhaul the system, upgrade facilities, and end the cycle of sewage spills polluting Scotland’s rivers and beaches.
