Southern water welcomes Government’s commitment to legal duty to reduce storm overflows

Southern Water has today welcomed the Government’s announcement that it will amend the Environment Bill, currently going through Parliament, to include a duty on water companies to deliver a reduction in discharges from storm overflows. This development is in line with Southern Water’s commitment to dramatically reduce pollution incidents and the use of storm overflows.

A storm release happens when, in order to protect people’s homes and businesses, schools and hospitals from flooding, water is released through a combined sewer overflow (CSO). This usually occurs during periods of heavy rainfall and around 95 per cent of these releases are rainwater.

Ian McAulay, Southern Water’s CEO, said: “We welcome the strengthening of the Environment Bill, and we are proceeding immediately with action and investment.  We are already acting now to cut pollution incidents by 80 per cent over the next four years and we believe we can achieve a similar reduction in storm releases by 2030. 

“All 83 of our bathing waters meet strict European standards, a challenge which 20 years ago seemed impossible, but was delivered. Now we want to take the next steps which is why we are investing over £2 billion on improving our wastewater network. This investment is on track and is already making a tangible difference in communities across our region.

“Another visible and public example of our commitment to tackle this problem is our industry leading Beachbuoy app. This provides near real-time information on releases of stormwater and is part of our drive to be as transparent as possible. This initiative will make it easy for everyone to hold us to account in reducing storm overflows and we are confident our customers will see a real improvement as our investment programme begins take effect.

“In order to go faster and further we are already looking at innovative solutions to reduce storm releases while ensuring value for money. We think it is achievable with the right partnerships and collaboration underpinned by policy. The first of these proposals, all incorporating nature based approaches, will be published for consultation in the next few weeks.


To ensure action happens we have today launched a dedicated task force which will work with customers and regional stakeholders to focus on reducing the number of these incidents as quickly as possible. We are certain a holistic approach, working with local government and stakeholders is the way forward to reach the targets we all want to achieve .”
