Question
To ask the Secretary of State for Environment, Food and Rural Affairs, with reference to the Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs' oral contribution on 20 October 2021, Official Report, c. 843, whether he will publish the assessment behind the cost range of ending raw sewage discharges into rivers as cited by the Minister during that debate.
Answer
The age of our Victorian sewerage system means a complete elimination of discharges from storm overflows would be extremely challenging and initial assessments suggest it could cost over £150 billion according to the Storm Overflows Evidence Project, commissioned by the Storm Overflows Taskforce. The full research report will be published shortly.
