Water Resources Management Plan: Teddington

Sarah Olney Excerpts

Wednesday 6th September 2023 Westminster Hall

[Munira Wilson]

I could not agree more with the hon. Lady, my constituency neighbour, and I will make that very point in my speech.

However, I will just briefly set out what the proposal is. It is to abstract millions of litres of fresh water from the Thames in my constituency and transfer it across London to the Lea Valley reservoir during times of drought. To replace that fresh water, Thames Water plans to pump millions upon millions of litres of treated effluent from Mogden sewage treatment works into the river at Teddington. That is millions upon millions of litres of treated sewage being dumped every day—not just in times of drought, but every day—into a tranquil yet lively hotspot for fishing, boating, paddleboarding and even wild swimming.

If that was not enough, the scheme threatens to wreak havoc on the local environment before a single drop of treated sewage even enters the Thames. That is because a new pipeline will have to be drilled underground from Isleworth to Ham, which means constructing eight access shafts. Each shaft will require a sizeable construction site, with conservation areas such as Ham Lands and recreation grounds such as Moormead Park being put at risk. Residents do not want their river harmed and they do not want to see their green spaces turned to rubble.

I congratulate my hon. Friend and constituency neighbour for securing this extremely important debate. She mentioned Ham Lands, which is in my constituency of Richmond Park. It is a local nature reserve that the local community has spent decades trying to protect. It has a unique ecology; it is home to many rare plants, lichen and fungi. Yet incredibly Thames Water proposes to build up to six major construction sites on Ham Lands, each one half the size of a football pitch. The plans include the permanent—I emphasise permanent—destruction of five acres of vital wildlife habitat. In total, 24,000 people have signed a petition against the scheme. Does she agree that the community has made its views very clear and that the Government must now listen?

[Munira Wilson]

I thank my hon. Friend and constituency neighbour for that important intervention; I could not agree with her more. Thames Water has conducted a consultation, but its response to its own consultation, published just a few days ago, makes it abundantly clear that it has not listened to public opinion or taken due regard of the impact on the very precious environment on which it is seeking to build.
