Video: The Sponge Effect
00:00 This is a sponge.
Imagine this sponge is the forested land around our reservoirs.
After lots of rain, the land around our reservoirs is nice and damp.
So when rain falls, it runs off the wet ground into the reservoir –
helping to increase our water storages.
We need consistent rain to keep the catchment damp.
If we have less rain,
the land around the reservoirs dries out.
This means that when rain falls, it gets absorbed by the parched landscape
and little runoff makes its way into the reservoir.
This is called the sponge effect
Climate change means we are experiencing warmer and drier weather with less rainfall.
By combining water efficiency measures with regular orders from the desalination plant,
recycled water and stormwater harvesting, we create a buffer in our water storages to
ensure Melbourne’s water supply remains secure.
