Improving river water quality
We're using standardised and repeatable construction in delivering works to improve river water quality, protect sensitive habitats and enhance biodiversity.
Safeguarding the health of local watercourses
We’re using standardised and repeatable construction techniques in delivering a £750 million programme of work to improve river water quality, protect sensitive habitats and enhance biodiversity.
Our customer, Anglian Water, is delivering a record level of investment in its phosphorus removal programme. Phosphorus is an essential nutrient in water that plays a crucial role in aquatic ecosystems, but excessive amounts can have harmful effects. Addressing this challenge at scale is a critical step in safeguarding the health of local watercourses.
Working as part of Anglian Water’s @one Alliance, we’re supporting the delivery of 245 individual schemes, each designed to reduce phosphorus concentrations in treated wastewater.
This latest phase builds on the achievements of AMP7 (Asset Management Period), during which Anglian Water invested £338 million across 170 sites to reduce phosphorus releases and improve environmental outcomes. During AMP8, Anglian Water is expanding the scale of this work, reflecting increasingly stringent environmental standards and growing public and regulatory expectations around water quality and ecological protection.
The programme is being delivered by the @one Alliance. This brings together eight strategic partners: Anglian Water Services, Balfour Beatty, Binnies, Barhale, Mott MacDonald Bentley (MMB), MWH Treatment, Sweco and Skanska. Working alongside a wider supply chain, the Alliance operates as an integrated team, combining expertise across design, construction, commissioning and long-term asset performance.
Standardised and repeatable construction
One of the defining strengths of the @one Alliance model is its focus on standardisation and repeatability. Skanska’s Chris Good, Delivery Director for Water Recycling in the Anglian Water’s @one Alliance, explains the many positive impacts this approach has: “By developing standardised designs and delivery approaches, the Alliance is able to accelerate programme delivery, improve safety, reduce cost and minimise carbon impacts. Enhanced programme planning and a long-term view of asset performance also enable more resilient solutions, ensuring that investments made today continue to deliver benefits well into the future.”
The work currently being delivered represents only the beginning, with the programme designed to ensure compliance with demanding environmental requirements while protecting ecosystems for generations to come. This emphasis on legacy and sustainability reflects Anglian Water’s broader commitment to creating a resilient water network that balances customer needs with environmental stewardship.
The scale of the phosphorus removal programme demonstrates how targeted, proactive investment can address some of the most pressing challenges facing the water sector.
As AMP8 continues, the phosphorus removal programme is expected to play a key role in setting new benchmarks for the industry. Through collaborative delivery, innovation and a clear focus on long-term outcomes, Anglian Water and the @one Alliance partners are showing how large-scale environmental programmes can be delivered efficiently and responsibly. For communities across the region, the benefits will be cleaner rivers, healthier ecosystems and a more sustainable water future.
