3.6 million hours
Date
3.6 million hours of sewage spills in 2023 in UK.
By the way, this is almost double the amount of the previous year. Sewage spills happen for example after heavy rainfall. In those moments, water will not go to a treatment plant, but will be released untreated into rivers, lakes or the ocean. A dry toilet could help to lower the spills.
