THE water quality in Bicentennial Park's ponds is set to improve after a floating wetland was installed last October.
A Rockdale Council spokesman said the council put it in to improve the health of the water.
The system is designed to remove dissolved pollutants such as nitrogen and phosphorus which promote algae and duck weed.
"The roots of these [wetland] plants grow down below the 'mattress', providing an environment for microbes and bacteria which can feed on the nutrients [nitrogen and phosphorus] in the water," the spokesman said.
"As the plants grow, more and more of these pollutants are removed.
"This process improves water quality in the ponds, provides habitat and food for fauna in the ponds, reduces the chance of blue green algae outbreaks, is cost effective, requires very little maintenance and only occupies a small portion of the ponds."
The council plans to increase the size of the artificial wetland.
Has the artificial wetland improved the area?
