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.
