Some of Bolton’s oldest gas mains are to be upgraded as Cadent is set to invest £80M to modernise the North West gas network.
Cadent, which manages the region’s gas network, will modernise around 418km of its North West pipeline - some which is more than 100 years old - over the next 12 months.
This is the same length as 4,000 football pitches, or the same height as more than 2,600 Blackpool Towers.
And in Bolton, 11,288 metres of pipe is to be upgraded.
The £80m investment will be delivered by 600 gas engineers who will be upgrading pipes to plastic to ensure a long-term safe network, as well as remain on track to replace fossil gas with hydrogen.
This change is said to be essential to achieve local plans for meeting energy demands in ways that better protect the planet.
Every year Cadent replaces around 1.5 per cent of its 34,000km North West underground distribution system.
These are mostly ageing metallic mains nearing the end of their safe operating lives.
The work is part of a bigger 30-year engineering programme, which is happening across the UK and is due to finish in 2032.
Head of Investment Planning Office (North West) Mark Syers, who leads the team delivering Cadent’s gas mains upgrade work in the region, said: “More than 80 per cent of homes in the North West rely on gas for central heating and it’s our job to make sure they get it, safely and reliably, every minute of every day of the year.
“As our older stock reaches the end of its safe working life, we must replace it.
“We’re also excited by the arrival soon of hydrogen to our networks, which is going to be essential to the North West achieving its targets to reduce carbon emissions.
“In most cases we’re able to insert the new pipe into the old one, a technique that reduces the time of each project and means we don’t have to dig as much.
“It also means an end to what often becomes increasingly-frequent visits – with associated disruption – to repair faults on the older metallic mains, as they start to show signs of age.
“We know it’s not ideal, but my team is determined to move as quickly as they safely can and get the work done with as little disruption as possible.”
Cadent works with the local highways authorities to agree the best and least disruptive timings to carry out these essential upgrades.
Once start dates have been confirmed, letters are sent to properties impacted ahead of the work starting.
Part of the programme also involves replacing individual ‘service’ pipes of tens of thousands of properties at no extra cost for customers.
Cadent makes all the arrangements and gives advance notice of when work will happen.
Gas remains on throughout, although in some cases properties that take a direct feed from the pipe being replaced will lose supply for up to 12 hours, as their building is connected to the new main.
Customer teams are available to answer any questions.
