Melbourne Water

Its jurisdiction includes all the reservoirs, lakes, wetlands, canals and urban creeks, and the sewerage and drainage systems that services the city.

It manages Melbourne's water supply catchments, sewage, rivers and major drainage systems throughout the Port Phillip and Westernport region.

It will also help protect the Merri and Moonee Ponds Creeks by virtually eliminating sewage overflows that can occur after heavy rain.

It reports on storage levels on Thursday each week[9] while an interactive graph compares actual use.

Further reviews of restrictions were needed to counter an ongoing drought, poor rainfall, record low storage levels and rising water use compared with past years.

[10] Around 80% of Melbourne's water is sourced from uninhabited forests in the Yarra Ranges and Central Highlands.
