From new pipes and pumping stations to storm tanks and nature-based wetlands, the @one Alliance is delivering better infrastructure for today and tomorrow – with hundreds of essential improvements across our water and water recycling network.

 

Together, we’re investing £3 billion between 2025 and 2030 to make our infrastructure stronger, more sustainable, and ready for the future.

 

Making improvements where they matter

Our region is growing quickly, and our network needs to grow with it. The @one Alliance is helping us do just that. Building new pipelines to bring water to more homes, improving treatment sites to protect the environment, and strengthening parts of the network that need more resilience.

Right now, we’re working on over 800 projects with each one carefully planned to make a difference now and for generations to come.

Putting our customers first

We know that construction work can be disruptive, especially when it takes place close to homes, schools and roads. That’s why we have Customer Experience Specialists involved in every single project, making sure we make the right engineering decisions for customers from the very start and avoid disruption wherever we can.

We also keep in touch with customers in lots of different ways, from traditional letters to text messages, social media updates, local newspaper coverage and working closely with community groups. However we reach you, we want to make sure you feel informed, supported and listened to.

Adding value to local communities

We want every project we deliver to leave a positive legacy. That’s why we run school workshops on science and engineering, support festivals and volunteering in communities, and partner with local organisations to make a difference where we can.

 

We’re also working with nature wherever possible. From building wetlands to manage water more sustainably, to designing low-carbon solutions that protect wildlife and help us reach our goal of net zero by 2030.

Working as one

The @one Alliance brings together eight specialist partners – Balfour Beatty, Barhale, Binnies, MMB, MWH Treatment, Skanska and Sweco, who all work side by side as one team.

Together, the Alliance delivers half of our capital investment programme, combining deep technical knowledge with a shared commitment to doing the right thing for our customers, communities and the environment.

A 20-year track record of delivering

We first introduced the @one Alliance in 2005, making us one of the first in the water industry to work in this way. Since then, the Alliance has grown, adapted and delivered thousands of essential projects across our region.

Over the years, we’ve continued to raise the bar, delivering improvements that support growing communities, protect the environment and help us move closer to our goal of net zero carbon by 2030. From 2015 to 2020, we delivered over 800 schemes across the region. Between 2020 and 2025, we delivered another £1.2 billion programme of upgrades. And now, as we celebrate 20 years of the @one Alliance, we’re looking ahead to our most ambitious investment yet – a £3 billion programme running from 2025 to 2030, as part of our wider £11 billion business plan.
