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

 

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

 

Making improvements where they matter

Our region continues to grow, and with that comes increasing pressure on water and wastewater infrastructure. The IOS Alliance is helping Anglian Water respond to this challenge. Strengthening ageing assets, improving treatment performance and ensuring networks can operate reliably during periods of high demand and extreme weather.

At the same time, IOS is tackling some of the most important environmental priorities. This includes reducing storm overflow impacts through Event Duration Monitoring and Flow Monitoring programmes, alongside introducing real-time river water quality monitoring.

Across AMP8, IOS is supporting the delivery of major investment programmes, including over £92 million in monitoring improvements, £166 million in continuous water quality monitoring, and £59 million in first-time sewer connections. Each programme designed to improve resilience, protect the environment and provide greater transparency for customers.

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.  Along with volunteering in communities, and partnering with local organisations to make a difference where we can.

 

Every project delivered through IOS is designed to create lasting benefits beyond the asset itself. From connecting properties to the public sewer network through S101a schemes, to improving the quality of local rivers and watercourses, the Alliance is helping to enhance the places where people live.

Environmental improvements are at the heart of this work. Reducing pollution, improving biodiversity and providing greater visibility of river health through continuous monitoring. Supporting stronger, healthier ecosystems across the region.

At the same time, IOS ensures infrastructure keeps pace with growth. Helping communities remain resilient, protected and supported both now and into the future.

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.
