Details

Reducing sewage discharges from storm overflows is an important priority to protect the environment.

This research, the first assessment of its kind, was commissioned by the Storm Overflows Taskforce – made up of Defra, the Environment Agency, Ofwat, CCW, Blueprint for Water and Water UK – and funded by Water UK.

The independent research, carried out by Stantec, presents a detailed overview of potential approaches that will act as an important evidence base for government action.

Defra subsequently commissioned an addendum in February 2022. This uses the same methodology to test additional policy approaches under consideration.

Defra published a consultation on the government plan on storm overflows on 31 March 2022.
