UK contractor PP O’Connor, based in Salford, has won a contract awarded by Celtic Technologies to carry out bulk earthworks, remediation and ground stabilisation required for the enabling works for the £170 million (US$262 million) modernisation of the Davyhulme Wastewater Treatment Plant in Manchester, which is the largest of its kind in the north-west of the UK. The upgrade is intended to improve the quality of water entering the Manchester Ship Canal.
Charmaine O’Connor, chief executive of PP O’Connor, said: “Our work at Davyhulme 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 (8.8 million cubic feet) 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 completed by the end of 2015, with the site then handed over to the main construction partners, Laing O’Rourke Imtech Joint Venture (LORI) on behalf of United Utilities, to complete the works.
