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

To ask the Secretary of State for Environment, Food and Rural Affairs, whether his Department has made an assessment of the potential merits of introducing higher penalties for the failure of water companies to adequately (a) monitor and (b) report on sewage spills.

For too long, water companies have discharged unacceptable levels of sewage into our rivers, lakes and seas.

Since 1 January 2025, water companies have been required to publish data related to discharges from all storm overflows within one hour of the discharge beginning. The Secretary of State has authorised Ofwat to carry out enforcement action for this duty, in accordance with the powers conferred under sections 18 and 141DA (4) of the Water Industry Act 1991. Ofwat’s enforcement powers provide for a wide range of enforcement activity, including substantial penalties.

Ofwat is monitoring compliance with the duty to report relevant data in real time. Where it detects non-compliance, it will take appropriate enforcement action. In addition to this, the Water (Special Measures) Act 2025 has introduced an equivalent duty for water companies to publish data related to discharges from all emergency overflows within one hour of the discharge beginning. Once commenced, this duty will be enforced in the same way.

The Independent Water Commission, led by Sir Jon Cunliffe, will make recommendations to shape further action to transform how our water system works and clean up our waterways for good. A public Call for Evidence closed on 23 April, with all interested parties invited to share their views. The review's final recommendations will be published and shared with the UK and Welsh Governments this summer.
