United Utilities has announced a new partnership with seven leading engineering and infrastructure firms to deliver the largest investment in water and wastewater infrastructure in the North West in over a century, pending the approval of the company's business plan.

The company has submitted a £13.7 billion investment plan for 2025-2030 to economic regulator Ofwat that would deliver cleaner rivers, more reliable water supplies and improvements to services for customers, communities and the environment.

The investment would support 30,000 jobs, including 7,000 new jobs within the company and wider supply chain, bringing investment in skills and opportunities to the heart of local communities and contribute £35 billion of economic value across the region.


Following a competitive tender process, those selected to work alongside United Utilities are C2V, (a VolkerStevin/Jacobs joint venture), Costain, Jacobs, Murphy, Kier Integrated Services, Mott Macdonald Bentley, and MWH Treatment. Bringing together skills and capabilities from across the UK and Europe allows the company to access the best use of expertise and innovation to work collaboratively and at pace to deliver real transformation for customers and the environment in the North West.

The partnership would be responsible for over £3bn of major infrastructure in the region including upgrades to wastewater treatment works and reducing storm overflow activations by delivering the largest spill reduction programme in the UK, protecting more than 500km of rivers and bathing waters.
