ACCIONA has announced a major upgrade to the Coppermills water treatment facility in the UK, a crucial site that supplies one-third of Greater London’s drinking water. The company will be responsible for the design, construction, and commissioning of the new infrastructure, which includes key enhancements to the facility’s electrical systems to ensure long-term reliability.

Thames Water will manage the facility post-completion.
The £400 million ($531 million) investment aims to meet the growing drinking water demands of London’s expanding population. Upon completion, the upgraded facility will be transferred to Thames Water, the private company that handles water distribution in the capital. Located in the Lea Valley, the Coppermills facility serves 32 boroughs, in addition to central London.
To execute this project, ACCIONA has partnered with Jacobs, which will serve as the principal designer. The joint effort will focus on constructing a new pumping station and implementing an advanced filtration and treatment system. These upgrades are designed to enhance the plant's capacity and efficiency, supporting the long-term sustainability of water supply in the region.
ACCIONA has had a significant presence in the UK since 2003, with a track record of successful projects. In early 2022, the company secured a contract to develop the Edmonton EcoPark waste-to-energy facility in North London, which will process 700,000 tons of waste annually and provide electricity and heating for about 50,000 households. Additionally, ACCIONA is involved in the NESS Energy Project in Aberdeen, Scotland, which has a treatment capacity of 150,000 tons per year.
With operations in over 40 countries, ACCIONA generated €17.02 billion ($19.09 billion) in sales in 2023, solidifying its position as a global leader in sustainable infrastructure development.
The Coppermills upgrade reflects the company’s commitment to supporting essential services and addressing the needs of rapidly growing urban populations. Through this project, ACCIONA is reinforcing its role in enhancing the sustainability and resilience of the water infrastructure in one of the world’s largest metropolitan areas.
