We own and operate more than 450 kilometres of stormwater channels and pipes across Greater Sydney. We work closely with local councils and other agencies to improve the health of our waterways, provide opportunities for stormwater reuse, and protect people and properties from flooding. Discover the projects that are underway.
It's important to us to work with local councils and other agencies to manage Sydney’s stormwater system to maintain and improve our large, or ‘trunk’, stormwater channels and drains.
One way we do this is through 'naturalisation'. Naturalisation greatly improves habitat for native birds and other animals. Our riverbank naturalisation projects, such as those at Powells Creek and Alexandra Canal, involve removing concrete from the steep channel walls and creating a more gently sloping edge stabilised with native plants and sandstone.
We focus onto improve the ability of our urban environments to capture, treat and reuse stormwater before it has a chance to pollute and degrade our creeks and rivers. Our Waterway Health Improvement Program is an example of water sensitive urban design.
Location – Various suburbs across Sydney
Timeframe – Ongoing
We're removing silt, sand and sediment from our wastewater and stormwater pipes. Learn more about our silt and debris management program.
Location – Annandale, Brighton-le-Sands, Campsie, Canterbury, Concord, Croydon Park, Glenwood, Kellyville and Strathfield
Timeframe – These projects are at various project phases, and some have been completed.
We're naturalising and revitalising creek and river banks in areas across Sydney including Cooks River and Caddies, Johnstons, Powells and Strangers creeks.
This work involves removing old concrete and damaged banks and replacing them with natural-looking banks. Learn more about our waterways projects.
As rainwater runs from roofs, roads and parks, it can pick up and carry pollution into stormwater drains. Types of pollution include litter, sand, dirt, grease, oil and metals.
Our infrastructure improves the quality of stormwater entering local waterways, such as through trash racks and sediment traps. We’re also using
We manage and build wetlands in some parts of Sydney as part of this stormwater management. Wetlands have a significant role in improving the ecology and water quality of streams and rivers, as they treat stormwater run-off from streets and industrial areas before it enters local waterways.
Location – Beaumont Hills, Glenwood, Kellyville, Rouse Hill and Stanhope Gardens
Timeframe – Ongoing
We’ve developed a strategic stormwater management plan in Northwest Sydney in what is known as the Rouse Hill development area. This includes regenerating bushland in stormwater drainage land and naturalising creeks such as Strangers Creek in Kellyville.
Our strategy will help reduce flood risk to properties and restore local creeks and waterways. It will also improve water quality entering the Hawkesbury–Nepean River.

Botany Wetlands are the largest coastal freshwater wetlands in Sydney, covering a 4.5-kilometre corridor in Sydney's east. We own the wetlands and lease most of the surrounding area to golf clubs. The wetlands have significant ecological and heritage value and provide important recreational, education and scientific value to the community.
The identifies how we'll:
We consulted with key stakeholders to identify the values, threats and opportunities outlined in the plan. We'll continue to collect and analyse data to help us protect and improve the wetlands.

We’re improving waterway health and liveability by treating stormwater before it enters our creeks and rivers. We’re working with local councils to reduce the amount of litter and pollutants in waterways by planting naturally vegetated stormwater treatment areas in parks across Sydney. These projects will help:

We work with councils and other agencies to investigate opportunities to collect and reuse stormwater.
There are over 70 projects across the Sydney region that collect and reuse stormwater. These projects include:
