Understanding annual storm overflow figures

The Environment Agency's annual returns report storm overflow monitoring information supplied by water companies. Spill counts use the regulatory 12/24-hour block method, so a counted spill is not necessarily a single uninterrupted discharge. Duration is the reported total time in spill, rather than the volume of sewage discharged. Monitor operation indicates the percentage of the reporting period for which the monitor operated. Missing values, incomplete monitoring and changes in recorded outlet details can affect comparisons between years. These annual figures describe historical reporting periods, not live discharge conditions or the cause of sewage problems at an individual property.
