RAW sewage could have been pumped into Scotland’s rivers, lochs, and seas every 90 seconds last year, according to a new report by campaign group Surfers Against Sewage (SAS).

While Scottish Water recorded 23,498 sewage discharges lasting a total of 208,377 hours in 2024, this accounts for only 6.7 per cent of the company’s total network, the research found.

Just 1,116 of Scottish Water’s 4,080 “combined sewage overflows” — where sewage is released directly into waterways or the sea — appear on its real-time sewage discharge map.

That 73 per cent data gap means SAS’s Safer Seas and Rivers Service providing sewage alerts across Britain is forced to leave Scotland blank, but their latest report estimates the public are being put at risk with as many as 364,629 effectively unreported discharges a year — amounting one every 90 seconds.

SAS chief executive Giles Bristow slammed “Scottish Water’s reckless approach to monitoring and public safety.”

He said: “Scotland’s coastline, lochs and rivers are some of the most stunning on the planet, with surfers, swimmers and paddle boarders wanting to make the most of these beautiful blue spaces.

“But these waters are far from pristine.

“With no legal requirement to issue sewage alerts in Scotland, water users have no idea whether or not it’s safe to enter the water.

“People are getting sick and yet Scottish Water are standing idly by, happy to sweep the scale of the sewage scandal in its waters under the carpet.”

Director of environment, planning and assurance for Scottish Water Professor Simon Parsons responded: “The route map we published in 2021 set out a crystal-clear commitment to invest further, monitor performance at more locations and strive to prevent pollution incidents before these happen.

“We are on track to deliver on those commitments.”
