                    The natural water cycle is impacted by buildings, concrete and sealed surfaces. As a result water can not soak into the ground and stormwater is created.

                    ​​Stormwater is rain that is collected on roofs, roads, footpaths and other sealed surfaces. It flows directly into our waterways, via our drainage network. During this process, the stormwater collects pollution, including sediments, oils, nutrients, metals, plastics and other litter, and carries them into our rivers.  

                    When water is not able to soak into the soil, as it does in the natural water cycle, it impacts the health of plants and trees, and also stops groundwater infiltration. This can contribute to a loss of biodiversity and an increase in the urban heat island effect.  ​

                    City of Melbourne practises integrated water management restore a more natural water cycle and to adapt to and mitigate the effects of climate change. By managing water in this way we can reduce flood risk, increase urban cooling and prepare for future drought. 

                    See below the many actions you can take to support sustainable water use in Melbourne.
