    Creative solutions to environmental problems in Centennial Park

Duck Pond, Centennial Park, Sydney

Duck Pond is one of the most popular and beautiful spots in Centennial Park – but all is not as well as it could be. That’s where a bit of creativity and floating ingenuity is coming to the rescue!

Recently, thanks to grant funding provided by the Greater Sydney Local Land Services, we are currently undertaking a project to install aquatic plants in Duck Pond for water quality improvement.

What’s the problem?

The water quality in Duck Pond is poor because of stormwater pollution and an over-abundant bird population. The water quality issues result in toxic blue-green algae blooms, which are harmful to humans and aquatic ecosystems.

What is the solution?

With a little creativity and innovation, we have developed and installed a series of ‘floating wetlands’. The floating wetlands, made up of eight rafts that are anchored to two of the islands in Duck Pond, aim to be an effective system for removal of nutrients, suspended solids, heavy metals, as well as providing oxygenation.

The wetlands will intercept nutrients from bird droppings washing off the islands and into the pond

We are using the natural power of wetlands as a long term solution for managing algae.

In addition, an aquatic planting program (around 2,000sqm in size) is being rolled out along the southern bank of Duck Pond.

Through this program we will assist the Greater Sydney Local Land Services in treating stormwater pollution and improving water quality in the Botany Bay catchment.

Another project under the Sustainable Parklands Program.
