Sediment and Erosion Control Around the Parramatta River


The suburbs around the Parramatta River are booming and with increasing population and activity comes new construction, developments, home-building, as well as increased public expectation for a quality, local waterway which they can safely use for leisure activities.

Did you know that up to four truckloads of soil from a building site can be washed away in a single storm if not properly contained? If sediment such as soil, sand, dirt and mud are not properly managed on building sites they can directly pollute our river and cause severe environmental problems, making it less safe for people to use.


Get the Site Right is a joint taskforce between the NSW Environment Protection Authority, the Department of Planning and Environment, Parramatta River Catchment Group, and its member councils. We are working together to target developers and enforce best practice on building sites, to protect the Parramatta River and surrounding environments and continue on the positive path to making the river swimmable again.

How sediment spills affect our environment and river:

  • Direct pollution of the Parramatta River by filling it with dirt, soil, sand and mud. This leads to poorer water quality, affecting swimming or leisure activities in and around the river.
  • Destroys aquatic habitats and smothers native plants and animals that live in the river
  • Blocks stormwater drains leading to flooding and overflows
  • Erodes river and creek banks
  • Causes health and safety risks such as slippery roads and tripping hazards

There are rules that developers need to follow to contain and manage sediment on their work site in a responsible manner. It is against the law to breach these rules. Local councils and the NSW Environment Protection Authority have the power to issue penalties from $8000 to $15,000 for each incident.

We all have a part to play in protecting the Parramatta River and making it swimmable again

Report sediment spills or pollution incidents by calling the NSW Environment Line on 131 555 or contacting your local council.

If you are building or renovating a home, submission of a Sediment and Erosion Control Plan is required before works begin. Ensure your builders are adhering to the rules - contact your local council for more information. 

If you are a developer or managing a building site, download a quick summary of the facts or consult the NSW Environment Protection Authority’s ‘Blue Book’ for detailed rules and guidelines.

Contact your local council or the NSW Environment Protection Authority for further consultation.
