AtkinsRéalis

Water is an increasingly important but unevenly distributed resource globally. AtkinsRéalis supports the water, wastewater and water-related environmental sectors with services from water strategy planning and flood management to infrastructure design and maintenance.

Water supply and quality is constantly challenged by growing populations, climate change, pollution and changing lifestyles – it’s a complex industry which requires the right skills and the right people to ensure that water services are fit for today and tomorrow.

Driven by the need to help clients deliver greater value for their customers, we’re constantly pushing research and innovation boundaries with a comprehensive range of services from water strategy planning to infrastructure design and maintenance.

In the water industry, there’s no such thing as an off-the-peg project, that’s why we value close working relationships built around the right people. We work side-by-side with our clients to ensure that their water services are fit for today as well as tomorrow, and together, we challenge existing methods and develop new solutions, whether that be the introduction of new assets or extracting more value from existing ones.
