Stormwater naturalisation projects

Our stormwater naturalisation projects are in the Campsie, Canterbury, Croydon Park, Kellyville and Strathfield areas.

These projects are underway and some have been completed.

Naturalising river banks improves local habitats for native birds and other animals.

About stormwater naturalisation projects

We're working to naturalise creeks and river banks. This involves removing old concrete walls and replacing them with stabilised banks of native plants, trees and rocks.

Our naturalisation projects improve the stormwater system, the local environment and provides a habitat for native birds and animals.  

Cooks River - Campsie, Canterbury and Croydon Park

The Cooks River was originally a natural river but by the mid-1900s, concrete panels were built along the 'unruly' natural river banks.

Some sections of the concrete channel were in poor condition and needed to be replaced with more natural riverbanks. The work we did has helped improve the natural environment and character of the river.

Strangers Creek - Kellyville

Strangers Creek is a tributary of Caddies Creek, which has undergone significant urban development since the 1990s.

This naturalisation project involves rehabilitating the creek banks and establishing a habitat for fauna. This will help to restore the natural environment and character of the creek.

Powells Creek - Strathfield

Powells Creek was a meandering natural water channel until the mid-1930s when the current concrete channel was constructed.

This naturalisation project will improve the environment and ecological value of Powells Creek. Work will involve replacing a section of concrete banks that are in poor condition with sandstone and natural vegetation.

Cooks River - Campsie, Canterbury and Croydon Park

Construction started in July 2013 and finished in early 2015. 

Strangers Creek - Kellyville

Detailed design is underway. We'll provide more information to stakeholders and the local community as the project progresses.

What is river bank naturalisation?

River bank naturalisation can take different forms. It generally involves removing some, or all of the steep concrete channel bank and creating a more gently sloping bank. The bank is then stabilised with native plants, trees and rocks.

Naturalisation creates a softer landscape feel and greatly improves the river bank habitat for native birds and other animals.

Wetlands can also be established as part of the naturalisation process. Wetlands have a significant role in improving the river’s ecology and health by treating stormwater run-off from streets and industrial areas before it enters the river.

Why can’t we naturalise all concrete creek and river banks?

We can only naturalise banks that have deteriorated and where we have enough space and a suitable budget to do the work.
