Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government when the results of the Storm Overflow Assessment Framework will be published for storm overflows potentially discharging untreated sewage into English rivers; and on what occasions there have been (1) overflows where untreated sewage can be lawfully discharged other than as a result of exceptional rainfall, and (2) overflows where untreated sewage cannot be lawfully discharged other than as a result of exceptional rainfall.

Outcomes of the Storm Overflow Assessment Framework (SOAF) investigations within calendar year are reported through the annual Event Duration Monitoring (EDM) reporting from Water and Sewerage Companies to the Environment Agency at the end of February the following year. The Environment Agency publishes these EDM reports by end of March each year.

The Environment Agency will publish the 2023 EDM report in March 2024 and this will contain outcomes from SOAF investigations completed by December 2023. The Environment Agency will assess data provided by each water company in order to assess whether they are meeting their legal obligations with regards to the discharge of untreated sewage.
