United Utilities, the North West’s water supplier, said it submitted a £13.7 billion investment plan for 2025-2030 to water services regulator Ofwat, which it said would create cleaner rivers, more reliable water supplies and improve its services for customers.

The company, based in Warrington, announced a partnership with seven leading engineering and infrastructure businesses to improve water and wastewater infrastructure. 

It said the plan would support 30,000 jobs, including 7,000 new jobs within the company and wider supply chain, and contribute £35 billion of economic value across the region.  

Following a competitive tender process, the firms 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. 

The partnership would be responsible for over £3 billion 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. 

Jane Simpson, Capital Delivery Director at United Utilities, said: “We’re really excited that we have secured some strong delivery partners to ensure we can deliver on our ambitious plans to transform infrastructure and services in the North West.”  

“It will be our most ambitious programme yet and by putting this partnership in place with some of the best design and construction companies in the country, it allows us to get to work quickly and deliver the transformation that we know our customers want to see.”
