OverviewUkpollutionscotlandwater
The amount of wastewater leaving the treatment works is measured and often referred to as ‘flow’. If there’s heavy rain, the sewer network may struggle to cope with the amount of wastewater and rainwater in it. The screened wastewater, which can be around 95% rainwater, is released through storm overflows. The storm overflows act as a pressure valve to release excess water through outfalls into rivers and the sea. This protects homes and communities from flooding. Releases from storm overflows are called spills. Flow data is reported every year to the Environment Agency.
