Peacocke Northern Transfer Mains Project

Keeping the customer satisfied

PROJECT: Peacocke Northern Transfer Mains Project CONTRACTOR: CB Civil CLIENT: Hamilton City Council VALUE: $22.3m

Hamilton city is growing. The Peacocke Northern Transfer Mains, for Hamilton City Council, is part of the initial tranche of works to facilitate the new Peacocke Development area.

This complex project required the installation of around 5.5km of twin rising main (630OD and 355OD) and 0.5km gravity pipeline from the Cobham/Wairere Interchange area to connect to the Far Eastern Interceptor (FEI) bulk wastewater system.

Works required pipe to be installed in depths of two to six metres, in difficult ground conditions, high water tables and immediately adjacent to the busy Wairere Drive, and commercial and

residential properties. Pipes were installed using a mixture of open trenched and trenchless solutions which also included an under rail trenchless pipeline crossing, inlet and transitional structures, live operational tie ins, significant protection, relocation and replacement of existing underground and overhead services and reinstatement of roads, 89 4CONSTRUCTION EXCELLENCE AWARDS 2022 CCNZ / HIREPOOL parks and walkways.
