£3 Billion Overhaul of North West Water Artery to Create Hundreds of Jobs

North West – A monumental £3 billion deal has been struck to upgrade a vital water pipeline in the North West, a project set to secure the water supply for over 2.5 million people and create hundreds of new jobs across the region.

United Utilities has awarded the contract to refurbish the historic Haweswater aqueduct, a crucial 68-mile pipeline that has been carrying water from the Lake District to homes and businesses from Lancashire to Greater Manchester for nearly 70 years. The refurbishment has been described as 'one of the largest water infrastructure programmes across the UK'.

The contract has been awarded to Cascade Infrastructure, a consortium of international partners with a proven track record of delivering similar large-scale tunnelling schemes in Europe.

The massive undertaking is expected to generate a significant economic boost for the region, with around 1,200 people employed at the peak of the programme. An apprenticeship scheme will also be established, providing valuable training opportunities for the next generation of engineers and construction professionals.

Work on the ambitious scheme is scheduled to begin in 2026. The project will involve replacing six separate tunnel sections of the aqueduct, with the majority of the construction taking place deep underground to minimise disruption.

Modern technology will play a key role. Workers will use high-tech tunnel boring machines (TBMs) to construct the six new tunnels, which will stretch a total of 50 km (31 miles). This stands in stark contrast to the construction of the original aqueduct, which began in 1933 and took 22 years to complete, relying on manual hand-digging and blasting techniques.

Remarkably, the refurbished aqueduct will retain the ingenious gravity-powered design of its predecessor. Starting its journey at Haweswater Lake, which sits 250 metres above sea level, the water will travel 110 km to its destination in Bury, 100 metres above sea level. This 150-metre drop allows gravity to naturally pull the water through the pipes, a sustainable and energy-efficient method of transport.

United Utilities has stressed its commitment to reducing the impact of the construction on local communities. The use of advanced TBMs means the project will require fewer large tunnel lining rings, which in turn will result in 3,000 fewer HGV deliveries on local roads.

The project is also pioneering a new financial approach. It is the first in the UK water industry to be delivered through a Direct Procurement for Customers (DPC) model, a structure specifically designed to provide better value for money for customers.

The overhaul of the Haweswater aqueduct represents a critical investment in the region's future, ensuring that a reliable and resilient water supply continues to flow from the Cumbrian fells to millions of homes for decades to come.
