Work is powering ahead on the Mardi to Warnervale water pipeline, with crews commencing boring activities and pipe laying at Mardi.
Installation is underway of a section of pipeline using trenchless technology called Horizontal Directional Drilling (HDD).
It involves the boring of a 1.4m diameter hole through the earth to a depth of 40m then pulling the fully welded 800m pipe back through the hole and connecting it to the water line, which is laid in a trench at either end of the bore hole.
This technology will be used to install the pipe under Porters Creek, Wyong River and the Coastal Wetlands at Watanobbi, with minimal impacts on the environment.
Crews have started boring activities at Mardi Rd, Mardi, and it is expected that work will take about six weeks, working seven days a week.
Other crews will be laying the water line in a trench along the edge of Collies La and Mardi Rd.
Construction of the pipeline in the Warnervale area has started, with the preparation of the construction corridor and the stringing of water pipe along the construction route in readiness to be welded, and the pipe is then laid in the trench and backfilled.
There’ll be a greater presence of work crews and equipment along Albert Warner Dr as the water pipe is being installed and the start of the Warnervale valve house construction.
