In 2025, Welsh water companies reported more than 100,000 sewage discharges, totaling over 800,000 hours of sewage released into natural water bodies. This figure marks a decrease from the previous year's 970,000 hours, attributed partly to dry weather conditions. However, concerns persist regarding underinvestment and enforcement in managing sewage pollution.
Environmental groups highlight that sewage discharges continue to pose health risks, with reports of sickness linked to sewage reaching 215 in 2025. The Welsh government and water companies are committing to significant investments and reforms to address these issues and improve water quality.
