A partnership between Hyder Consulting and Mott MacDonald has been appointed by the Laing O’Rouke Imtech joint venture to provide detailed design and project management services for a multimillion pound expansion of United Utilities’ Davyhulme wastewater treatment works.
Details were announced last week of the main contract which has a potential value of between £123 million to £171 million to Laing O'Rourke Construction Ltd and Imtech Water Waste and Energy Ltd.
Davyhulme treatment works is the largest in the north west, serving a population of more than one million people and has iconic status as the site where modern wastewater treatment, specifically the aeration settlement process, was invented over 100 years ago. The upgrade will establish a further advancement in wastewater treatment, adopting modern design and construction techniques such as building information modelling (BIM) and design for manufacture and assembly (DfMA).
The modernisation programme is expected to improve the quality of water entering the Manchester Ship Canal and involves significant remediation of previously abandoned land. Following this, six circular primary settlement tanks and a large activated sludge plant with 10 circular final settlement tanks will be constructed.
The project team will use digital engineering, BIM and DfMA processes, allowing the plant to be built virtually before starting construction on site. All parties have previously used DfMA on similar wastewater treatment facilities and will use this experience to complete the works while the existing plant remains fully operational.
Hyder’s director Rob Dustan said:
“Hyder is delighted to be collaborating with Mott MacDonald on this prestigious project. The design approach will be industry leading and make full use of BIM technology to ensure a world-class solution that stands the test of time”.
Mott MacDonald’s project director Des Chalk added: “Davyhulme has been selected as an exemplar project by the team and significant efforts will be made to drive new innovations, sustainability initiatives and much more throughout the detailed design. BIM underpins our drive for innovation and sustainability and will enable us to deliver this project quickly and efficiently.”
The Davyhulme wastewater treatment works expansion is due to be completed in 2018.
