Laing O'Rourke and Imtech are to begin a joint venture (JV) multimillion contract to modernise the Davyhulme Waste Water Treatment Works in Manchester .

Appointed by United Utilities, the modernisation programme 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). This work will lead to significant environmental benefits for the site.

The JV will employ industry leading digital engineering and Design for Manufacture and Assembly (DfMA) processes, allowing the project team to build the plant virtually before starting construction on site, providing definitive information to allow ease of commissioning and optimise long-term operation and maintenance.

Graham Flynn, Laing O'Rourke Imtech Project Director added: "We are delighted that United Utilities has selected Laing O'Rourke Imtech to help Davyhulme Waste Water Treatment Works become one of the UK's most efficient and sustainable waste water treatment plants. 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."
