DM Civil has used trenchless technology to deliver a series of water infrastructure upgrades in Perth.
The company was contracted to provide construction services to relocate existing water systems with new placement waters mains, as well as remove or grout fill abandoned water pipes under Armadale Road, near the intersection with Nicholson Road.
To complete the pipeline works, which incorporated some of the city’s vital water supplies, DM Civil collaborated with key stakeholders to minimise disruptions to residents and businesses, as well as on project specifics like pipeline design, replacement and construction logistics.
The company replaced 90 m of the Serpentine trunk mains under Armadale Road, which involved the removal of each main and installation of new pipeline.
Additionally, DM Civil installed butterfly valves on the existing mains, replaced existing cast iron water reticulation mains and laid 1,050 m of DN 800 mild steel cement lined pipe, which included several auger boring excavations, including one under a high pressure gas main.
All works were completed without incident and were concluded with the demolition, removal and disposal of existing redundant steel reinforced concrete valve pits, valves and interconnected pipework.
