Why our drainage system matters

Storms and floods are a natural part of Melbourne’s weather, but they can have a big impact on our way of life. As the city grows and the weather becomes more unpredictable, managing stormwater safely is more important than ever.
At Melbourne Water, we manage the city’s complex drainage system to reduce flood risk and help keep our rivers, creeks and bays healthy.
