Yorkshire Water is about to embark on its largest infrastructure investment of the last 20 years, tackling poor performing assets, as it starts a five-year plan to replace more than 1000km of water mains.
In the first year alone, Yorkshire Water is investing £89m to replace 238km or 147 miles (equivalent to a return journey from Leeds to Hull) of water mains with durable, flexible plastic pipes. The second year of the programme will see 211km of mains replaced throughout Yorkshire.
The new replacement mains are built to withstand high pressure and temperature variations resulting in fewer bursts, lower leakage and a reduction in water supply disruptions to customers.
Yorkshire Water is targeting poor performing assets that will benefit most from mains renewal as a priority in areas prone to disruption, bursts and supply interruptions such as Kiverton Park, York, Sheffield, Sowerby Bridge, Harrogate and Stannington.
Mains replacement work will take place right across the county from Barnsley, Rotherham, Doncaster and Sheffield to the east Yorkshire coast, Hull and North Lincolnshire. York and North Yorkshire will see 43km and 90km of new mains respectively by the end of March 2026, as the county undergoes a major replacement programme.
Works of this scale are difficult to complete without causing disruptions to the community, but Yorkshire Water’s capital delivery programme manager Lee Boshell said the company will do its best to keep disruptions to a minimum.
“We’re deploying trenchless techniques wherever possible to reduce disruption by tunnelling under the road in some instances to prevent the need to dig a trench across a whole street or road,” he said.
“We will be working hard to provide as much notice as possible to customers, partner organisations, stakeholders and commuters about work happening in their area and proposed timescales.”
“We have already identified our first two years’ worth of mains replacement and we’re working towards year three of our five-year programme. Having long term visibility of the programme of works allows us to work closely with Local Authorities, Highways and other utility providers, so that we can collaborate with them to renew mains and other services in one go.
“This is an important investment for our business and our customers and will help us to improve the performance of our clean water network to reduce leakage and supply interruptions for our customers. We know that delivering this work, which involves relaying mains under busy roads and in major towns and cities in the region, will inevitably cause disruption, but we will be doing everything we can to keep this to a minimum.”
The mains replacement programme is part of Yorkshire Water’s largest ever environmental investment of £8.3 billion to improve infrastructure focussing on issues we know our customers really care about such as:
- £1.5 billion to reduce storm overflows into the region’s watercourses
- £360 million to prevent nutrient pollution in watercourses
- £327 million rolling out smart meters to help customers save water and reduce their bills
- £51 million to increase our asset resilience
- £98 million to install water quality monitors in rivers so we can identify and respond to pollution reports quicker
- £75 million for environmental protection and improvements
- £99 million to improve drinking water quality
