£170m upgrade to water treatment plant
A £170m modernisation programme is planned for Davyhulme Wastewater Treatment Plant – the largest of its kind in the North West.
Salford-based contractor PP O’Connor has been appointed by Celtic Technologies to carry out the bulk of the earthworks.
The site, west of junction 10 of the M60 motorway at Trafford, Macnhester, serves a population of more than a million people.
The upgrade is expected to improve the quality of the water entering the Manchester Ship Canal and is expected to take 36 months to complete.
PP O’Connor chief executive Charmaine O’Connor said: “Our work at the Davyhulme Wastewater Treatment Plant will pave the way for the expansion and upgrading of this essential infrastructure site. As with all our projects, our aim is to recycle as much material as possible for re-use on the project, this will include treatment of contaminated soils and other excavated materials.”
PP O’Connor will excavate, sort and remediate approximately 250,000 cubic metres of the land to create three new piling platforms on to which the new facilities will be built. This will include the on-site decontamination of soils and the crushing of excavated rubble and bricks for re-use within the works.
PP O’Connor’s work is expected to be complete by Christmas, then the site will be handed over to the main construction partners Laing O’Rourke Imtech Joint Venture (LORI) on behalf of United Utilities, to complete the works.
The modernisation programme involves significant remediation of previously abandoned land, followed by construction of six circular primary settlement tanks (PST) and a large activated sludge plant (ASP) with 10 circular final settlement tanks (FST).
