Melbourne Water is owned by the Victorian Government and plays a major role in the total water cycle.

Werribee wastewater treatment plant and sewage disposal system
The second stop for the group was the Werribee wastewater treatment plant. In this treatment plant, wetlands are specifically constructed to remove pollutants from stormwater run-off. By using wetlands, nutrients such as nitrogen and other pollutants can be filtered, suspended solids can be also removed by sedimentation ponds constructed at wetland inlet points.

Besides acting as a natural filter, the wetlands at the Western Treatment Plant at Werribee also attract an amazing array of wildlife. The wetlands are declared a Wetland of International Importance under the Ramsar Convention, and they can house an estimated 65,000 birds at any one time.
