Project description

NSW Govt developed the project in 2009 to provide accommodation for nearly 500,000 people over the next 30 years. The new release areas in the north-west were provided with infrastructure to ensure the availability of potable water, recycled water, wastewater and storm water before development took place.

  • Package 1 delivered drinking water and wastewater infrastructure to Alex Avenue and Riverstone precincts. This included a new reservoir at Rouse Hill, and drinking water, wastewater and recycled water infrastructure to North Kellyville. Completed in 2011.
  • Package 2 and 3A delivered drinking water and wastewater infrastructure to Alex Avenue, Box Hill, North Kellyville, Riverstone, Schofields and Vineyard. Completed in 2015.

Killard Infrastructure were awarded works for Stage 2 and 3A which included the following:

  • Laying over 9.5km of ductile iron pipe for work lots 4A, 4B and 5 in Edmund, Clarke, Guntawong and Tallawong Roads in Riverstone
  • Laying and welding of 15km steel pipe to link the Marayong Reservoir, Cudgegong Reservoir and planned Box Hill Reservoir.

This project demonstrates our ability to successfully deliver complex and critical construction projects in the water industry on time

Our experience and adaptability enabled us to work with a range of pipes of varying diameters and materials. Our involvement was crucial to meet the construction timeline for Sydney Water and other contractors with their concurrent infrastructure works.

This included our building of up to 6 pipelaying crews to meet the project timelines
