The water provider has chosen Costain to deliver management and delivery of its large-scale assets across the region in a deal worth an initial £175m over five years.
The deal with UU will start this month and run for an initial five-year period with a potential to extend for a further 10. It marks the first time UU has outsourced its maintenance activity as it looks to drive efficiencies across its infrastructure assets.
Under the deal, Costain will manage maintenance across 96 water treatment and 575 waste-water treatment sites across the North West. UU currently provides water to around 6m people in the region.
