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

To ask the Secretary of State for Environment, Food and Rural Affairs, how many times raw sewage has been released into the River Wandle in the past 12 months.

This government has increased monitoring requirements on water companies to ensure greater transparency, requiring them to have event duration monitors on all Combined Sewer Overflows to enable spill counting. An annual report, which includes the number and duration of spills that occurred on the River Wandle in 2021, is available here: Defra Data Services Platform
