Two Indeco hammers working on the banks of the Werribee river
The Werribee river is part of the Port Phillip catchment area located on the expansive lowland plain south-west of Melbourne, Victoria, Australia.
Just a few kilometres from the watercourse is the town of Eynesbury, for which the Victoria state government has planned to build a water recycling pipeline that will run under the river bed.
The area has one of the largest eucalyptus forests in the country, home to endangered flora and fauna, so any work must be carried out with minimal disturbance to the surrounding environment.
Great Western Water was contracted by the Victoria state government to install the pipeline. This was done by drilling two 15-metre deep wells to hold the drilling machine that will penetrate under the river.
The excavation of the two wells was awarded to Jaydo Construction, a company specialising in water infrastructures, sewerage and drainage systems, which owns a wide range of Indeco hammers: an HP 18000, 3 HP 12000, 4 HP 9000, 4 HP 7000, 2 HP 5000, 1 HP 4000 and an HP 2500.
The work was carried out by two Indeco hammers: an HP 12000 mounted on a Hitachi 69-tonne excavator to dig down to 11 metres and an HP 9000 for which Jaydo, with the support of the Indeco team and South East Engineering, designed an extension that would allow the machine to continue digging for an extra 3 metres to reach the scheduled 15 metres.
