Thames Water is installing a new water main in Baker Street as part of a £2.1 million project to make the network more resilient now and for future generations.

Engineers have been working in the road – made famous by literary detective Sherlock Holmes – to replace an old iron Victorian water pipe with a new tougher plastic one.

The company will insert the new plastic pipe inside the old iron one – a process called slip-lining and described as “the quickest and most efficient way of upgrading the pipe”, which is buried deep underground.

Chris Barwick, project manager, said: “This is a complicated job, but we’re working hard to get it done as quickly as possible.

“It is crucial work to make our water mains network more robust, making it less susceptible to leaks and bursts which can have damaging effects for residents.”

The plastic pipe measures 450mm in diameter, and will be inserted on the 300 metre stretch of pipe which runs underneath Baker Street, Marylebone Road and Park Road.

The project, which is being carried out by Thames Water’s eight2O alliance, started on July 24 and will take approximately four months to complete, with a road closure in place for the first two months. Pedestrian access will still be available, and some buses will also be diverted.

It is the next step in the water company’s mains replacement programme, targeting pipes in poor condition across the capital and replacing them, to reduce the risk of bursts.

Thames Water is working closely with Westminster Council during the project, as the council will be following the water company in working on the road, as it looks to reconfigure the one-way system into a two-way one.
