OEP launches investigation into the regulation of combined sewer overflows

The Office for Environmental Protection (OEP) has announced today (Tuesday, June 28) that it is to carry out an investigation into the roles of Ofwat, the Environment Agency and the Defra Secretary of State in the regulation of combined sewer overflows (CSOs) in England.

The aims of the investigation are to determine whether these authorities have failed to comply with their respective duties in relation to the regulation, including the monitoring and enforcement, of water companies’ own duties to manage sewage. In doing so, the OEP will seek to clarify the respective duties.

The OEP also stated that if there are found to be failures, their objective will be to improve regulation, leading to long term improvement in water quality.

The OEP’s Chief Regulatory Officer Helen Venn said: “Unsatisfactory water quality is an important, longstanding, systemic issue and one of the most pressing environmental concerns at this time.

“This is a complex area and there is already a great deal of work underway to try and tackle the problem of untreated sewage in our rivers. Our investigation will contribute to that work by providing clarity about the legal responsibilities of the different bodies involved to ensure measures to tackle the problems can be targeted and effective.

“We clearly do not know at this point what our findings will be or where the investigation will take us. It is possible that it could result in enforcement activity and / or in broader actions to improve the legal and / or regulatory systems. Our priority throughout will be to protect and improve the environment.”

The investigation follows a complaint submitted to the Interim OEP by Salmon & Trout Conservation UK.
