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.
