The consultant will provide Ofwat advice on projects and programmes associated with the new separate third-party investment model in assets known as Direct Procurement for Customers and ongoing Future Assets and Resources programme costings.

Richard Whale, managing director – Water at Atkins, said: “Our aim is to help the water industry deliver large projects in an effective way, ultimately ensuring customers get the best, and most cost-efficient, service.

“Our teams will bring their expertise from a range of UK water projects, big and small, to ensure the industry delivers in the best way possible.”

Atkins will advise on schemes including tunnels, water treatment plants, water transfer schemes and reservoirs.

Working with Ofwat and water companies, Atkins will advise on design, feasibility, risk and implementation, as well as running a rule over projects to ensure they meet regulation and customer requirements.

Atkins’ advisory role will initially run for a period of two years.

The appointment comes off the back of Atkins’ role on large water infrastructure projects including schemes for Wessex Water and Severn Trent Water and Thames Water as its Strategic Delivery Partner.
