Ryde to Pymble pipeline upgrade

Boosting water capacity for Sydney's North Shore

We’re bringing the Ryde to Pymble drinking water pipeline back into service by upgrading a vital connection to the Wahroonga Reservoir. The project will boost the water distribution system's capacity, ensuring we can meet the growing demand for drinking water and support continued housing growth across Sydney’s North Shore.


About this project

This original pipeline was built in 1936 and ran from the Sydney Water Ryde Pump Station along Victoria Road to Roland Avenue in Wahroonga. It served our customers well for over 70 years but was disconnected from the network in 2014 due to its age and condition.

We're now upgrading the water delivery system’s servicing capacity and increasing resilience of the Ryde system to help cater for increased growth across the North Shore.

This will be done by reinstating the drinking water pipeline between Ryde Pumping Station and the connection point at Roland Avenue, Wahroonga. The upgraded pipeline will generally follow the alignment of the old existing main and extend to the Wahroonga Reservoir.

The upgraded pipeline is designed for a 100-year service life, ensuring safe, clean, and reliable water well into the future.
