Sewage Discharges: South West

Sarah Dyke Excerpts

Wednesday 27th November 2024 Commons Chamber

[Ben Maguire (North Cornwall) (LD)]

The issue of sewage dumping in our waterways was one of the biggest concerns of residents across my North Cornwall constituency during the general election. And judging by the number of Members here today, I certainly was not alone in that. In the course of my speech, I will take the opportunity, first, to highlight the scale of the problem of sewage dumping and its effects on our communities; secondly, to set out what infrastructure improvements are badly needed to tackle this scandal; thirdly, to outline some of the regulatory reforms that are required; and, finally, to outline what South West Water must now do to end the scandal of constant sewage dumping in our beaches and rivers.

North Cornwall is a very rural constituency. We have several rivers, including the Camel, the Inny and the Allen. North Cornwall is also blessed with some of the most beautiful beaches in the world, including Harlyn, Summerleaze, Widemouth bay, Daymer bay, Polzeath, Crackington and many more. I was extremely fortunate to grow up in Cornwall where I learned to swim and surf at these incredibly beautiful spots. North Cornwall’s families and residents, young and old, thoroughly enjoy the waves at Mawgan Porth, the fishing villages of Padstow and Port Isaac and the breathtaking cliffs at Tintagel. They also enjoy the impressive sea pools in Bude and Boscastle.

The Environment Agency’s 2023 figures showed that the total duration of sewage overflows discharged into local rivers and waterways in the south-west region was 530,737 hours, which represented an 83% increase compared with 2022.

In 2020, Natural England notified Somerset councils that the phosphate levels in the Somerset Levels and Moors Ramsar site were too high, and thousands of homes are still caught in a moratorium. Alongside this, last year, there were 3,336 sewage spills in Glastonbury and Somerton, making it the most polluted constituency in the country. Does my hon. Friend agree that water companies should be investing in more sewage treatment plants and that the Government should introduce a sewage tax on water companies’ profits?

[Ben Maguire]

I absolutely agree on both of those points and I shall address them in slightly more detail in a moment.

In 2023 alone, many of the blue flag beaches in North Cornwall experienced more than 2,700 hours of sewage discharges across 148 separate incidents. This pollution, as my hon. Friend has just mentioned, is often linked to combined sewer overflows, which are activated during heavy rainfall to prevent urban flooding, severely compromising water quality and endangering swimmers and marine life.
