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

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps he is taking to prevent untreated sewage from entering rivers and seas in the UK; and what assessment he has made of the potential merits of increasing the penalties for water companies that breach the regulations on discharge.

Tackling the harm caused by sewer overflows is a top priority for this Department.

During periods of significant rainfall untreated sewage diluted by rainwater will discharge through storm overflows to avoid streets, premises and sewage treatment plants from being flooded. Water companies are committed in the five-year business planning period (2020-2025) to a significant programme of improvements to the monitoring and management of storm overflows at a cost of around £1.1 billion. This investment includes undertaking 800 investigations and 798 improvement schemes to provide environmental improvements by reducing spills from frequently spilling overflows.

I recognise that there is more to do to manage sewage pollution. I met water company CEOs and made clear that the volume of sewage discharged into rivers and other waterways in extreme weather must be reduced.

To achieve this, the new Storm Overflows Taskforce - bringing together Government, the water industry, regulators and environmental NGOs - has agreed to set a long term goal to eliminate harm from storm overflows. The Taskforce is now working on plans to start making progress towards that goal, and they have commissioned research to gather evidence on the costs, benefits and feasibility of different options.

We are introducing new duties requiring the Government to publish a plan by September 2022 to reduce sewage discharges from storm overflows and to report progress to Parliament on implementing that plan. We are also introducing duties requiring water companies and the Environment Agency to publish data on storm overflow operations on an annual basis. These legally-binding obligations on water companies and government will reduce pollution in rivers – protecting wildlife and public health.

Water companies are currently producing for the first time comprehensive Drainage and Wastewater Management Plans to assess the capacity of their wastewater networks. We are also taking key steps through the Environment Bill to require water companies to produce such Plans on a statutory basis. These plans will be another tool to help address the risks that storm overflows pose to the environment.

The Environment Agency uses a range of enforcement options ranging from warning letters to prosecutions. The Environment Agency has brought 44 prosecutions against water companies in the last five years, securing fines of £34 million. £7.9 million has also been donated to environmental and wildlife trusts organisations in the same period through enforcement undertakings. The Environment Agency will continue to prosecute water companies which fail to uphold the law or cause serious environmental harm.
