Celebrating its 20th anniversary this year, Anglian Water’s @one Alliance has taken on its largest ever portfolio of capital delivery work as part of Anglian Water’s AMP8 business plan, worth £11 billion. 

The Alliance, formed of partner organisations Anglian Water, Balfour Beatty, Barhale, Binnies, Mott MacDonald Bentley, MWH Treatment, Skanska and Sweco, was introduced in AMP4 (2005-2010) as a strategic delivery vehicle for Anglian Water’s Integrated Main Works programme. The Alliance has delivered nearly £4 billion of investment into the Anglian Water region so far in its 20 year partnership 

As Anglian Water’s first Alliance, the @one Alliance made waves in the water and construction industry due to its unique outperformance commercial model, which sees the Alliance tasked with delivering schemes below Anglian Water’s target cost – allowing Anglian Water to reinvest its efficiency savings back into new projects. 

This year has ushered in a new Asset Management Period (AMP) across the water industry, which will see the @one Alliance deliver over 750 projects that are worth over £3bn on behalf of Anglian Water. 

With AMP8 getting underway in April, the @one Alliance has already begun construction work on over 120 sites across the Anglian Water region, with more than 80 schemes entering the construction phase by the end of the first quarter.

Ian Hutchinson, the @one Alliance’s Managing Director, said: “I’m hugely proud of our alliancing model and everything we have achieved together – especially in this transformational time which will see @one’s output more than double.

“We’ve got some big targets to hit in AMP8 but there’s a lot to celebrate when it comes to our achievements over the last five years. We've delivered 672 schemes, reduced capital carbon by 65% and reduced operational carbon by 6,600 tonnes against our baseline.

“None of this would have been possible if it wasn’t for all the people who’ve given their time to make the Alliance what it is today. This milestone is really a celebration of their hard work and I'm excited to see how the Alliance continues to develop over the next five years.”

Last year, all eight partner companies signed to be continuing members of the Alliance to help deliver projects over the next five years for AMP8, helping the water company deliver its biggest ever investment programme for the Anglian Water region.
