Project goal:

Construct a new wastewater pipeline in Clarkson to extend the wastewater network in the northern corridor of metropolitan Perth.


In planning

Delivery Date:

2021 - 2022

What's happening?

To cater for growth and the disposal of wastewater flows in the northern corridor of metropolitan Perth, Water Corporation proposes to construct the following work in Clarkson and Neerabup:

  • Installation of 2kms of 1800-2200mm diameter wastewater main
  • Installation of eight access chambers

This work will take 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.

Proposed route for the Clarkson wastewater pipeline

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