Severn Trent is investing £60 million to upgrade Newark’s sewerage and water system to help protect homes from sewer flooding. The scheme will provide a reliable water source for decades to come. In 2016, Nick Wallace from Severn Trent explained that more than 12 miles of old piles will be replaced with new, larger ones.
In May 2017, Aarsleff worked on Queens Road in Newark, to facilitate the replacement of a tunnel with one at 1.5m diameter. Here, 28 (No.) sheet piles were installed.
As part of the same scheme, and for the same client, Aarsleff was awarded the contract to construct a sheet piled cofferdam on Harcourt Street. Aarsleff installed 46 (No.) sacrificial steel sheet piles, with pile width 600mm and 12.0m in length. There was a retained height of 10.2m, forming the overall cofferdam. Again, Aarsleff’s work will facilitate the replacement of an old water course.
