We are excited to announce that we have appointed the McConnell Dowell and Gamuda Joint Venture (MDGJV) to deliver the Ryde to Pymble drinking water pipeline. This partnership brings extensive experience in complex infrastructure projects and a collaborative approach to ensure sustainable outcomes for our community.

Together, we’ll work to provide world-class water services while minimising environmental and community impacts. In the coming months, you may notice site investigations such as geotechnical, ecological, and Aboriginal heritage assessments. We’ll keep you informed and contact you directly if property access is required.

We are 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 planning and design work, we need to do some investigation work, which will involve potholing and road cutting.

Your water services won't be impacted during this work.

Timing of investigations

Our investigations will take place from 12 February 2025 for 3 weeks, weather permitting. To minimise disruption, we will carry this work out during the night, from 9pm to 5am.

Once we've finished our investigations, we may return for further surveys. We'll write to you again to let you know before we start.

How will this work impact me?

We will be carrying out investigations on Victoria Road and Hermitage Road, West Ryde.

Traffic and parking changes

For the safety of our workers and the community, there will be partial lane closures where we are doing investigations, and we may need to use some parking spaces. We'll have 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.

Noise

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