Our urban catchments

We all live in a catchment, and so we all have the opportunity to affect the quality of our local waterways through the choices we make. It's up to us as a community to keep our waterways clean.

Our urban catchments

What is a catchment and subcatchment?

A catchment is the area of land that drains into a waterway (creek or river). Whatever happens in that catchment, affects that waterway. This is because the rainwater that runs off our roofs, roads and footpaths will eventually end up at the bottom of the catchment, along with whatever pollution it picks up on the way.

The catchment can be broken up into smaller areas known as subcatchments where all the rain falling in the local area flows to the same waterway (if you live in the Marrickville Council area it's either the Cooks River flowing to Botany Bay, or the Lower Parramatta River flowing to Sydney Harbour).

Gross pollutant traps

One of the ways Marrickville Council prevents pollution entering our waterways is by gross pollutant traps. See how much rubbish, litter and other pollutants are kept out of our waterways:

Cooks River Catchment – Botany Bay

Cooks RiverMost residents in the Marrickville Council area live in the Cooks River catchment.

The Cooks River is a dynamic river system that could potentially be a healthy natural environment within the urban landscape. The river and its foreshores provide a recreational resource valued by the local and wider communities – including sports groups, joggers, dog walkers, cyclists, anglers and boat users. Many people also want to be able to swim in the Cooks River.

The Cooks River's foreshores provide an ideal opportunity to restore and conserve a range of native plant communities and wildlife habitats. Today the river and its catchment is being managed to assist the natural recovery of water quality, aquatic life, river bed and enhanced river banks.

Lower Parramatta River – Sydney Harbour

Rozelle BayMany residents of Newtown, Petersham and Stanmore live in the Lower Parramatta River catchment.
