New gas and water pipes to be installed in Lewisham at the same time to minimise jams

New water and gas pipes are to be laid in Lewisham – using the same holes in the road, at the same time to minimise traffic disruption.

More than 1.5km of new water pipes will be installed in Lewisham by Thames Water to protect residents from disruptive bursts.

The £4.5 million project will happen alongside gas company SGN installing pipes between 16 and 22 inches in diameter in Westhorne Avenue, near the busy South Circular in Lewisham borough.

The two companies have been working with the Mayor of London’s Infrastructure Team, the London boroughs of Lewisham and Greenwich and Transport for London to deliver the project together.

Work is due to start on Monday (February 14) and will last for two weeks, before continuing on the road towards Clifton’s roundabout until September. The entire project is expected to be completed by November.

As part of an innovative “dig-once” approach, the water pipe replacement works will be carried out simultaneously as SGN replaces existing metal gas mains and services with modern plastic pipes, saving 14 days of disruption for residents and businesses.

Initial work started in Baring Road, Lewisham, last month and SGN will also be working in nearby St Mildreds Road, between the junctions of Birch Grove and Burnt Ash Hill, with a lane closure to ensure the safety of engineers and members of the public.

Last year, Thames Water announced London’s Victorian water network is set to receive a major overhaul to increase water resilience thanks to a £300 million contribution from Thames Water’s owners.

The unprecedented investment matches the £300 million already included in the company’s spending plans for the 2020-2025 investment period.

It will improve service by accelerating work to reduce leaks and bursts – increasing the resilience of the capital’s pipe network to the impacts of climate change and helping secure water supplies for future generations.

The South East is classified as “seriously water stressed” due to population increases and climate change and by 2040 it is forecast that demand in the region will outstrip supply by 414 million litres – the equivalent needed by around two million people – unless action is taken now.

However, a recent survey by water industry consumer champions CCW showed two in five people living in water stressed areas, including the south-east of England, think water is a plentiful resource ⁽¹⁾.

Kieran Ingram, Thames Water’s head of water networks, said: “A key part of our company turnaround plan is fixing the basics, and this important project will help us protect the water supply of thousands of Londoners for the future.

“By working collaboratively with SGN and digging just once for both water and gas works, we hope to reduce disruption for residents and motorists, saving an extra two weeks of work.

“As London’s population continues to grow and we deal with the impact of climate change, it’s more important than ever that we look after our water networks and ensure as much water as possible makes it to where it is needed.

“This work will ensure we have a robust water network in the area and allow us to continue providing a reliable water supply to our customers.”

Neil Baxter, Stakeholder and Collaboration Projects Manager at SGN, added: “We’ve worked closely with Thames Water and the local authorities in planning this work and we will be doing everything we can to limit disruption during our essential project.

“We appreciate that roadworks can be frustrating, however, the new plastic pipe has a minimum lifespan of 80 years.

This means once the work has been completed, Lewisham homes and businesses will enjoy the benefits of a continued safe and reliable gas supply for many years to come.”
