Atkins, working with Arup, has been appointed to work with Severn Trent Water Ltd. as part of their clean water strategic grid team. A key part of the grid is the Elan Valley Aqueduct, which is 120 kilometers long and provides water to Severn Trent's customers in Birmingham. Completed in 1906 and now in continual operation for over 100 years, increasing water demands of the city mean the infrastructure is beginning to show its age.
Using expertise from our multidisciplinary teams, we established options for the proactive maintenance and replacement of several sections of the Elan Valley Aqueduct (EVA). The objective of the work is to achieve Severn Trent Water’s aspiration for an asset fit for the 22nd Century.
Using our extensive water and tunnelling experience, we developed the outline design for the selected schemes, provided planning support and environmental guidance and assisted the client in compiling tender documentation for a design and build contract. The package of 3 schemes covers 4.2 kilometres of 3 metre diameter tunnel, with a capital cost of around £70million.
This was undertaken as part of a 10 year Engineering Consultancy Framework under which we assist Severn Trent Water in prioritising assets for investment and promoting the best TOTEX solution in achieving the best outcomes for STW and their customers.
