back to current projects

Project goal:

Upgrade wastewater infrastructure in Two Rocks and Yanchep


In construction

Delivery Date:

Late 2018

What’s happening?

In February 2018, Water Corporation will start work to upgrade the wastewater infrastructure in Two Rocks and Yanchep.

This work includes the construction of:

  • 4.2 km of wastewater main along Two Rocks Road in Two Rocks;
  • 1 km of wastewater main along Lisford Avenue in Two Rocks;
  • 1 km of wastewater main along the extension of Marmion Avenue in Yanchep;
  • new below ground wastewater pump station on Charnwood Reserve; and an
  • upgrade of the existing Abrolhos Close Wastewater Pump Station. 

Our authorised contractor is RCR Water. Their site office is located on Charnwood Reserve.

We are working with the City of Wanneroo to minimise impacts on the community as much as possible and expect to complete the upgrade work by the end of 2018.

What are the community impacts?

Traffic management and road closures

Zamia Rise will be closed to vehicles from Wednesday 30 May to mid-June 2018 to complete excavation work near the Zamia Rise and Two Rocks Road intersection. Detours will be in place at all times to maintain access via Violacea Road and Lindsay Beach Boulevard off Two Rocks Road. Two Rocks Road will remain open to traffic at all times. Work will be completed in this area between 7.00 am and 5.00 pm, from Monday to Friday as approved by the City of Wanneroo.

Residents and commuters will notice construction work from the intersection of Lisford Avenue and Sovereign Drive and as work progresses south along Two Rocks Road.

Traffic management will be in place to direct vehicles and pedestrians safely around the work area, with only partial road closures required on Two Rocks Road during some sections of work. Two Rocks Road will remain open to traffic at all times.

Private property

We will not require access to private property during this work.


The Bush Forever site along Two Rocks Road will not be impacted during this work. Some trees along the western side of Two Rocks Road reserve must be removed to install the new wastewater main.

We will work with the City of Wanneroo to replace the trees after construction work is complete.
