Teddington water petition falls short with just weeks to go

The Teddington water petition opposing Thames Water’s plan to draw river water at Teddington Weir and replace it with treated sewage effluent from Mogden has gathered 43,746 signatures, but it needs 100,000 to trigger a parliamentary debate by 1st November. With the clock ticking, petition creator Ian McNuff is urging residents across Richmond upon Thames to act now if they want their voices heard on a project that could fundamentally change the character of the Thames through the borough.

Thames Water says the abstraction site is essential to secure drinking water supplies for London beyond 2026, but local campaigners argue alternative solutions have not been properly explored.

What Thames Water is proposing

The scheme centres on Teddington Weir, where Thames Water wants to extract fresh river water during dry periods. Thames Water would then replace the removed water with treated effluent from the Mogden Sewage Treatment Works in Isleworth, creating what the utility calls a sustainable water cycle. The company frames the project as a necessary response to population growth and climate change, arguing that London’s water demand will outstrip supply within the decade. The Environment Agency has yet to issue a final decision on the abstraction licence, and Thames Water has emphasised that the treated water would meet stringent quality standards before release. For a borough that takes pride in its riverside walks and wildlife, the idea of replacing Thames water with recycled sewage has proven deeply unsettling.

Why the petition is struggling

Parliamentary petitions require 100,000 signatures within six months to be considered for debate in the House of Commons. Ian McNuff launched the petition to force politicians to scrutinise Thames Water’s plans and examine what he describes as viable alternatives, including greater investment in leak reduction and water efficiency programmes. The 43,000 signatures represent significant local concern, but the petition needs traction beyond Richmond upon Thames to reach the threshold. Many residents remain unaware the petition exists, and the technical nature of water abstraction can make the issue feel distant until you stand by the river and imagine the change. Thames Water currently loses around 24 percent of its water through leaks, a figure campaigners argue makes new abstraction premature. Getting 100,000 people to care about something as abstract as water abstraction is harder than getting them to care about a single tree or building, even when the stakes are equally high.

Ian McNuff, a Teddington resident, started the petition after concluding that Thames Water had not adequately justified why recycled sewage water should flow through a stretch of the Thames that supports everything from rowing clubs to protected wildlife. His campaign has drawn support from riverside communities who worry about water quality, ecology, and the precedent the scheme would set for future industrial use of the river.

What happens if the petition succeeds

Reaching 100,000 signatures does not block the project, but it does guarantee parliamentary attention. A debate in Westminster Hall would require ministers to explain the government’s position on Thames Water’s plans and give MPs from affected constituencies a platform to raise constituents’ concerns. It would also bring media scrutiny and potentially influence the Environment Agency’s licensing decision, which remains under review. Even if the debate changes nothing, it creates a public record and forces officials to address questions that have so far received only corporate answers. The petition closes when it reaches six months from its creation date, though the exact deadline has not been widely publicised. In planning battles and environmental disputes, public pressure does not always win the day, but silence guarantees losing it.

What this means for you

If you oppose the Teddington abstraction plans, you can still sign the parliamentary petition by searching for it on the official UK Government petitions website. Sharing the petition link with friends, neighbours, and community groups beyond Richmond upon Thames will help reach the 100,000 threshold, as parliamentary petitions count all UK signatures, not just local ones. You can also submit your views directly to the Environment Agency during any public consultation period on the abstraction licence, and contact your MP to ask them to monitor the application and raise your concerns with the relevant ministers. If you use the Thames Path, belong to a rowing club, or simply value the river as it currently flows, making your position known now is more effective than waiting for a decision you cannot influence. Keep an eye on Richmond Council’s planning portal and the Thames Water website for updates on consultation periods and licensing milestones. Civic participation works best early, and this project is still at a stage where public pressure can shape outcomes. The Teddington water petition has gathered significant local support but remains well short of the parliamentary threshold with time running out. Whether you sign, share, or simply stay informed, the next few weeks will determine whether this issue gets the scrutiny residents believe it deserves.

Teddington Weir has marked the tidal limit of the Thames since the 1800s. What was once a simple question of managing river flow has become a test of whether residents can influence the future of a waterway that defines this part of London.

Frequently asked questions

What exactly would Thames Water do at Teddington Weir?

Thames Water proposes extracting fresh river water during dry periods and replacing it with treated effluent from Mogden Sewage Treatment Works in Isleworth. The company argues this creates a sustainable water cycle and helps meet London’s growing demand.

Would the recycled water be safe?

Thames Water states the treated effluent would meet stringent Environment Agency quality standards before being released into the Thames. However, campaigners question whether those standards are sufficient for a river used for recreation, wildlife habitat, and drinking water abstraction further downstream.

How do I find the petition to sign it?

Search the UK Government and Parliament petitions website for Thames Water Teddington or the petition creator’s name, Ian McNuff. Parliamentary petitions are hosted on the official petitions.parliament.uk domain, and you will need to confirm your signature via email.

What alternatives to the abstraction scheme exist?

Campaigners point to Thames Water’s 24 percent leakage rate and argue that fixing pipes, improving water efficiency, and investing in reservoir capacity would reduce the need for new abstraction. Thames Water says it is pursuing those measures alongside the Teddington project.

Will the petition actually stop the project?

No. Reaching 100,000 signatures triggers a parliamentary debate, not a binding decision. However, it forces ministers to address the issue publicly, creates media attention, and may influence the Environment Agency’s licensing decision, which is still under review.
