The focal point of the scheme is a 20-metre diameter, 24-metre deep shaft tank that will add 5,200m³ of additional overflow storage capacity to the local wastewater network. Reports Contract Journal
This shaft will serve as a critical component of the wider, multi-site Etruria Vale project, being delivered under Severn Trent Water’s Framework Directive Scheme.
Barhale will undertake the construction using a secant piling technique to form a circular retaining wall, allowing for safe excavation of the shaft. The structure will be connected to existing infrastructure through two pipes – a 7.2-metre-long, 1200mm inlet pipe and a 12-metre-long, 1050mm overflow pipe – which will link to nearby manholes.
Barhale Director James Ingamells commented: “The Etruria Vale project encompasses several key locations, including the Lower Oxford Road CSO and the Lower Oxford Road Shaft. The Etruria Vale shaft represents the final and vital piece of the puzzle. Once completed, the added capacity it provides will significantly strengthen the local wastewater network.
“Crucially, it will support improvements to the water quality in the Fowlea Brook – a key tributary of the River Trent.
“Everyone at Barhale is proud to be delivering this important project on behalf of Severn Trent Water, and we look forward to continuing our strong collaboration to ensure its successful delivery.”
Ben King, Senior Project Manager at Severn Trent Water, added: “As we move into AMP8, I’m looking forward to working with Barhale on this significant scheme, which will bring long-term benefits to Stoke-on-Trent. Our shared focus on collaborative project delivery will be essential to ensuring we deliver the project successfully over the next two years.”
Construction is expected to be completed by summer 2027.
