What the different colour zones on the water dial mean
Green zone
This zone represents an average day's water use. At this level, we are usually able to cope well with demand.
Yellow zone
If our water use gets into the yellow zone, we may start to experience supply issues like reduced pressure.
Red zone
If our water use stays in the red zone for too long, we may need to implement restrictions, to help ensure fair and sustainable water supply across the city.
