Wales’ largest ever coastal survey underway

Wales coastline 3x2

The Dŵr Cymru Welsh Water (DCWW) Capital Delivery Alliance is undertaking the largest programme of scientific coastal investigation work ever completed in Wales.

The work delivered by the alliance – which comprises Mott MacDonald Bentley and joint ventures between Morgan Sindall/Arup and Skanska/Arcadis – will provide DCWW and its regulator, Natural Resources Wales, with the tools to help better understand and protect Wales’ coastal waters.

As part of the project, DCWW is investing over £8M in scientific investigations at 49 sites around the Welsh coastline.

The programme will include field surveys, water quality monitoring and mathematical modelling. The alliance will develop computer models of the Welsh coastal waters and carry out assessments of bathing and shellfish water to determine whether further investments are required to DCWW assets to maintain high levels of quality.

The alliance has also appointed water consultant Intertek to lead the modelling and compliance components and a specialist survey team, led by Apem and including CREH and Fugro, to deliver this programme of work.

“This project will make use of a number of innovative techniques, such as state-of-the-art modelling and microbial tracers, simulating coastal dynamics and pollutant transport, as well as the most advanced coastal survey technology ever seen. The study area covers over 2,700km of coastline, including more than 10 major estuaries,” explained Mott MacDonald Bentley’s Mark Dives, who is project manager of the alliance.

“The sheer scale of the task in hand – to gather a huge amount of historic data to feed the study and drive a substantial survey programme to gather new data – in the time available will provide a big challenge to the Capital Delivery Alliance,” added Dives. “However, we are confident in our abilities and expertise to undertake the project safely, efficiently and to achieve sustainable outcomes for the benefit of both DCWW customers and the environment.”

River and coastal survey work is already underway, with the project due to be completed at the end of the first quarter of 2017.
