Sydney Park wetlands.

Raingardens

For a while now, the Council has been installing raingardens whenever we repair or lay footpaths. You’ve probably seen them around, though you might not realise the important role they play.

Raingardens look like normal garden beds. The difference is they are specially designed to filter stormwater and stop pollutants flowing through our waterways, which lead to Sydney Harbour and the Cooks River.

The soil mixture in a raingarden retains and holds water, and the plants we use have deep root systems that easily absorb it, so we don’t need to use precious drinking water on these garden beds.

We are also installing stormwater harvesting systems, including one at Sydney Park (pictured above). The harvesting system guarantees the four wetlands at the park are sustainable and healthy.  Treated stormwater is used to top up the wetlands (which lose vast amounts of water to evaporation). This stops aquatic weeds from taking hold of the wetlands and also prevents algae blooms. Plus, the harvesting system we are installing in partnership with the Australian Government means we don’t have to use drinking-quality water in the wetlands.

Towards 2030, our raingardens and water harvesting systems are:

  • conserving water
  • reducing stormwater pollution
  • greening our streets.
