Work will see the significant remediation of previously abandoned land in advance of the construction of six circular primary settlement tanks (PST) and a new activated sludge plant (ASP) with ten circular final settlement tanks (FST).
The JV will employ digital engineering and Design for Manufacture and Assembly processes allowing the project team to build the plant virtually before starting construction on site.
This will allow the project team to complete the works while the plant remains open and fully operational.
Richard Sutton, United Utilities senior project manager, said: “Davyhulme is an iconic site where modern wastewater treatment was invented more than a hundred years ago.
“We are keen to get started on this next development in the plant’s history, to ensure we continue to serve the people of Manchester into the 21st Century.”
Graham Flynn, Laing O’Rourke Imtech Project Director added: “Our ability to maximise the benefits of modern, offsite construction and engineering techniques is central to our solution, meaning that we can deliver this complex scheme in a live environment with minimal disruption.”
The delivery team on the project includes Hyder Consulting and Mott MacDonald.
Rob Dunstan, technical director with Hyder-Mott MacDonald JV said: “The approach to the design will be industry leading and will make full use of BIM technology to ensure a world class solution that stands the test of time.”
