Project overview

To cater for growth and the disposal of wastewater flows in the northern corridor of metropolitan Perth, we are undertaking the following work in Clarkson and Neerabup:

  • Installation of 2kms of new wastewater pipeline, 2.2 metres in diameter
  • Installation of eight shafts and access chambers 

This work is taking place at the intersection of Connolly Drive and Walyunga Boulevard, through the Clarkson TAFE car park, towards Harmony Avenue, south along Hannaford Avenue, across Homestead Park, east along La Mirada Avenue, under the Mitchell Freeway and east along Hall Road in Neerabup.

Once complete, the pipeline will play a vital role in transferring wastewater flows from multiple wastewater pump stations to the Alkimos Wastewater Treatment Plant.


Neerabup National Park near Hall Road will be minimally impacted during this work. Some trees on the eastern side of Connolly Drive and within Homestead Park may need to be removed to install the new wastewater pipeline. We will work with the City of Wanneroo to replace the trees after construction work is complete.

Some bush clearing along Hall Road will be required to install the new wastewater pipeline. A rehabilitation plan has been agreed with the Department of Biodiversity Conservation and Attractions to rehabilitate and maintain the area after construction work is complete.

  • Reinstatement of the bus stop, footpath and kerbing is underway along Connolly Drive.
  • Once work is complete at the roundabout, reinstatement will be done with black asphalt, as agreed with the City of Wanneroo.
