New 1km outfall pipe arrives at Withernsea

A new 1km outfall pipe has arrived off the coast of Withernsea in the UK after travelling across the North Sea from Norway.
Work to install the new outfall pipe is part of a £26 million (€28.5 million) scheme by Yorkshire Water and its capital partners, Ward and Burke and Van Oord, to move its wastewater treatment works further inland due to coastal erosion.
The new pipe will be moved into place alongside the existing outfall pipe on 21 July, before being sunk to the seabed in the coming days.
Yorkshire Water project manager Matthew Brown said: “This scheme marks a substantial investment in Withernsea and the arrival of the new outfall pipe is a significant milestone in this important project.
“Work off the coast is due to continue until September as installation and checks are completed.
“During the dredging of the seabed in recent weeks we have not observed adverse water quality. However, we are continuing to monitor the bathing water throughout the duration of the works and the advice against bathing notice will remain in place as a precaution, in order to ensure public health is protected.”
The new treatment works, which is expected to be competed in summer 2021, will service wastewater for 15,000 people and be built using the more environmentally sustainable Aero-Fac system, with a low-carbon construction producing minimal odour and noise.
It will have no need for sludge removal, meaning no tanker movement and a reduced impact on traffic as a result.
