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

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will make an assessment of the potential merits of establishing an independent reporting mechanism for assessing sewage pollution by water companies.

We have increased the number of storm overflows monitored across the network in England from approximately 7% in 2010, to 100% coverage before the end of 2023. These event duration monitors will provide a complete picture of when, and for how long, each storm overflow operates.

Under our landmark Environment Act, we made it a legal requirement for companies to provide discharge data to the Environment Agency and to make it available in near real time to the public. By bringing in this comprehensive monitoring, this government and its regulators have enabled the extent of sewage discharges to be revealed, so we are better equipped to tackle this challenge.

In April 2023, we also launched our consultation on Continuous Water Quality Monitoring and Event Duration Monitoring. This outlines the government’s proposals to enhance the monitoring of storm overflow and final effluent discharges. Government’s response to this consultation was issued on 14 September 2023, and water companies are now taking forward plans to implement this programme from 2025.
