Chalk Streams: Sewage Discharge

I beg to move,

That this House has considered the matter of tackling sewage discharges in chalk streams.

One Friday evening, I received a text and photos from a desperate resident, Maz, as the numbers cranked up on the sewage discharge map, asking:

“Surely something can be done about our precious chalk stream!”

I had been following the situation, but as soon as I saw the photos of sewage-filled water flooding the roads, I called her straight away, saying:

“I am coming down—can you meet me there?”

Twenty minutes later and my Friday evening started by checking sewage and seeing trails of toilet paper and algae float by the side of the road next to one of the world’s rare chalk streams. The River Ver, one of the four chalk streams in Harpenden and Berkhamsted, had seen more than 1,000 hours of pollution through the sewage discharge overflow. To date, that number has reached more than 2,500 hours. That is just not good enough.

Chalk streams, long described as England’s rainforest, provide a unique environment. The stable temperature from running through chalk, combined with a high mineral content, means that chalk streams are the ideal environment for vegetation to grow and wildlife to flourish. As havens for the natural environment, chalk streams attract a diverse array of flora and fauna. From the green drake mayfly to the kingfisher, the brown trout to the endangered water vole, those precious rivers are home to a whole host of wildlife.

I commend the hon. Lady for bringing the matter forward. We are unfortunate not to have chalk streams in Northern Ireland, but we do have limestone rivers, which are equal in the aqua life they have and the health of the land. Does the hon. Lady agree that when it comes to ensuring that aqua life and the environment are sustained, we need to have short-term action and long-term protection?

Absolutely. The English chalk downland houses 85% of the world’s total. It is a privilege to say that in my constituency we are home to four of those rare and precious habitats: the River Bulbourne, the River Gade, the River Lea and the River Ver.

I, too, thank the hon. Member for securing a debate on this crucial issue. My constituency of Reading West and Mid Berkshire boasts several beautiful chalk streams. The Pang is one and it is said to have inspired “The Wind in the Willows”. I recently tested the water quality there with campaigners from the Angling Trust and found phosphate levels were three times what they should be. We would not find Ratty or Mole there any more, sadly, because that is a dangerous level of phosphate.

Order. Interventions should be brief.

I apologise. Does the hon. Lady agree that the previous Government let our chalk streams down when they abandoned their chalk stream plan? Will she join me in calling for urgent action to protect our chalk streams?

We have absolutely been let down by the last Conservative Government and we need to turn that around. Chalk streams and their catchment areas, such as the one in Harpenden and Berkhamsted, have been a lifeline around which our towns and villages have flourished, using the chalk streams to power thriving mill communities and supply the watercress industry. Even today, chalk streams form an important part of everyday life. Batford Springs and Redbournbury Mill are prime locations for families to paddle and play, especially on warm, sunny days. However, those precious habitats are under continued threat from pollution, from road run-off and sewage. Not one is in good overall river health.

I will give way to my hon. Friend the Member for Newbury.

Clive Jones.

I congratulate my hon. Friend the Member for Harpenden and Berkhamsted (Victoria Collins) on securing the debate, and I thank her for giving way—as I do my hon. Friend the Member for Newbury (Mr Dillon).

My constituency of Wokingham is blessed with the River Loddon, which flows across its boundaries. It is a rich, biodiverse environment and a reminder of the beauty in our natural world, yet the scourge of sewage discharges persists. Thames Water must make the necessary infrastructure investments to halt its appalling record, but the company’s future is far from certain and those plans may be undermined.

Order. Can you bring your comments to a conclusion? This is a very short debate, but there are long interventions.

Does my hon. Friend agree that the Government must ensure that these investments proceed, no matter the financial position of Thames Water?

Absolutely. These are vital investments that have to go ahead.

Locally, many organisations have worked tirelessly for many years to highlight the importance of precious catchment areas and protect them. From the Chiltern Society, the Ver Valley Society, the Chilterns Chalk Streams Project, the River Colne Catchment Action Network and the Herts and Middlesex Wildlife Trust to local volunteers at Batford springs, Friends of the Bulbourne and the Not Bourne Yesterday project—

I thank my hon. Friend for giving way and congratulate her on securing the debate today. In Epsom and Ewell, we have two chalk streams, which are important not only ecologically, but for our cultural heritage. The Hogsmill river is a chalk stream so serene that it provided the perfect setting for John Millais’s painting, “Ophelia”. Knowing the ecological and cultural significance of Hogsmill, it has been sad to see its water quality worsen due to pollution. In September alone, sewage overflowed into Hogsmill for over 30 hours. Does my hon. Friend agree that our chalk streams, including the Hogsmill, are not just local treasures, but part of our national heritage, and that swift action is needed to protect them against degradation from sewage discharges?

Absolutely. Many of my constituents are horrified at the local state of rivers and frustrated by the lack of progress, and feel compelled to attend the march for clean water on Sunday 3 November. Sewage pumping in our rivers is hugely damaging for the local environment, contaminating the water with unacceptably high levels of phosphates and nitrates, and poses a major health risk.

I thank my hon. Friend for securing this debate. Does she agree with me, and with Action for the River Kennet, that the requirement for sewage treatment works should be based not only on the population size they support, but the importance of the waterways they protect, such as the Lambourn and Kennet chalk streams that flow through my constituency of Newbury?
