Ryde to Pymble pipeline upgrade

Reinstating the Ryde to Pymble drinking water pipeline

We are carrying out investigations to understand the location and condition of the existing drinking water pipeline. Then, we will consider options for the alignment of a new pipeline.


About this project

We're considering reinstating the Ryde to Pymble trunk main, a drinking water pipeline that runs from Ryde Pump Station on Victoria Road to the Wahroonga Reservoir site on Roland Avenue.

As part of our early planning and design work, we need to do some investigation work to assess the ground conditions. The investigation work will include potholing to get soil samples.

Benefits

The new pipeline will:

  • increase the water distribution system's capacity for servicing the increase in drinking water demand in the area

  • cater for increased growth within the North Shore

  • have a 100-year design life.

Impacts

There will be partial lane closures where we are doing investigations, and we may need to use some parking spaces. There will be signage in place to let you know where changes apply, and our traffic controllers will help keep traffic flowing around our work area while keeping you safe.

There will be noise from the potholing and road cutting. We will do our best to keep noise to a minimum.


Project timeline

Please note this is an estimated timeline.

July to September 2025: Design and construct contract award
October to December 2025: Commence enabling works
