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.

A spokesperson for Veolia responded: “We operate the Seafield Waste Water Treatment works in line with the SEPA licence conditions and everything that leaves the plant has been treated. 

“Even during significant rainfall, the works are designed and operated to ensure all wastewater goes through our screening, grit removal and settlement processes before being discharged. 

“We work with the local community, SEPA and Scottish Water to provide an effective service for residents and the environment and support continuous improvement works. We have a doors open policy where members of the public, councillors, MPs and MSPs can visit the site.”

At the Seafield Wastewater Treatment Plant, there is only one exit point of the plant with two outfalls. This is where final effluent (fully treated wastewater) leaves the facility.

In times of significant rainfall, contents from the settled storm overflow or settled primary overflow tanks would also be discharged from this point.

These discharges are licensed and only take place under significant rainfall events in full accordance with the site’s licence.. All discharges are treated to some extent and no raw sewage is discharged from the plant.

These should not be classed as “dumping events”. Storm discharges are continuously monitored, and the data shared with Scottish Water and SEPA

Veolia did operate a wastewater contract in the Highlands with Scottish Water and at the end of its contract period it transitioned back to Scottish Water as originally agreed after 25 years of successful service. This was not due to any inference of poor performance.

Veolia is required under the licence at Seafield to report data to SEPA and this has always been done in compliance with the licence.

As Veolia is a private company working with Scottish Water, our operations are sampled every day, which is more frequent than regulated water companies.

This is an additional level of scrutiny and gives greater assurances that we are compliant with our SEPA licence.
