Asked by: Lord Cameron of Dillington (Crossbench - Life peer)
Question to the Department for Environment, Food and Rural Affairs:
To ask His Majesty's Government what assessment they have made of the merits of ending operator self-monitoring of sewage overflows.
Answered by Baroness Hayman of Ullock - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
Since 01 January 2025, water companies are required to publish data related to discharges from all storm overflows within one hour of the discharge beginning (under section 141DA of the Water Industry Act 1991 as inserted by section 81 of the Environment Act 2021).
Data must be published in a way that is accessible to the public and in a form that allows the public readily to understand it. To support this, Water UK have launched a central hub that provides discharge data of every storm overflow in England on a single website.
To further support understanding of the impact that sewage discharges have on the receiving watercourse, a programme to rollout Continuous Water Quality Monitors near storm overflows and sewage treatment works is beginning in Price Review period (PR24), which runs from 2025-2030. Monitors will be installed at 25% of assets in scope for the continuous water quality monitoring programme in the next Price Review 24. Sites prioritised for monitoring will be based on Defra’s priority areas, such as those that impact designated bathing and shellfish waters.
Combined, these measures are creating an unprecedented level of transparency, enabling the public and regulators to see where, and how often, overflows are discharging, and to hold water companies to account. Where breaches of legal requirements are identified as a result of this data, regulators won't hesitate to take action.
