How many sewage spills have happened in your part of Scotland?

It is difficult to assess how the numbers compare to the previous year's figures, when 24,000 spills were recorded because of lower coverage. The sites are all licensed to release untreated or partially-treated waste but just under 12% of overflows are legally required to report their data to the regulator, the Scottish Environment Protection Agency (Sepa).Sepa said it has a "risk-based approach" which prioritises areas for monitoring based on population and environmental need.However, none of the new monitors were required to be reported to Sepa.Scottish Water figures, external show that Glasgow's River Clyde was one of the most impacted waterways in Scotland last year, receiving almost 6,150 spills - or the equivalent of 17 a day.When adding in the Clyde Estuary, Firth of Clyde and other unnamed tributaries that run into the Clyde's waterways, this almost doubles to nearly 14,200, or 39 a day.The Clyde Estuary also recorded the longest duration of spills - more than 25,000 hours - followed by the River Clyde with more than 15,000 hours.Barcloy Mill Burn in Dumfries and Galloway, which is one of the newly-monitored sites, received the most spills last year, with a total of almost 3,500.The data suggests that 225 sites recorded no spills and 525 recorded fewer than 10. There may also be errors which suggest a monitor is active when it is not.
