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

To ask His Majesty's Government, further to the requirement set for companies by the Environment Agency that new flow monitors be installed on wastewater treatment works, what update can they provide on the progress of these installations.

Water companies are installing new monitors at sewage treatment works that have storm overflows which control the flows of sewage that they treat. These monitors will record when there is an overflow of the incoming sewage into storm tanks and other flow monitors will record the flow that is being passed forward for treatment while the overflow is operating. Around 400 sewage treatment works have had both of these monitors installed so far in AMP7, all such discharges will be fully monitored by the end of 2026.

These monitors are being installed to ensure that when these overflows operate, they only do so when the required flows are being treated by the works.
