We're investing in our region by replacing trunk mains in London. Trunk mains will be replaced at:

• Pentonville Road
• Mile End Road
• Baker Street
• Isle of Dogs 

Our trunk mains have the important role of moving large volumes of drinkable water. They move water from treatment works across the network to various service reservoirs. That's how we get clean drinking water to your taps.

Much of the trunk main network was built in the early 19th century using simple techniques. There often wasn't consistent quality control when creating the water mains. This is why it's important to replace and upgrade them.

Due to the New River’s vital role in supplying part of London with water, we must ensure we take great care of it.

Over the years, we’ve been carrying out many small-scale repairs of leaks and we have put in place different solutions in an attempt to manage the leakage in ways that minimise disruption locally. However, our annual inspections have identified further areas of leakage and we have decided that a large-scale repair is now necessary.

We are looking to refurbish a section of the New River channel at Eade Road, between Green Lanes and Seven Sisters Road, to prevent leakage and extend the asset life. This will ensure unhindered water flow in the channel for the London Water supply and that the amenity remains safely open for the benefit of the local residents and the public.

The planned work will ensure the structural integrity of the New River and mitigate future flood risk. This proposal is currently in the early planning stages, and we’ll of course continue to keep you updated.
