Our Water Resources

 Last Update: 29 June 2018


Current levels: Near normal

Although rainfall in May was slightly below the long-term average, the wet start to spring has helped groundwater levels recover, and it is unlikely that restrictions will be needed this year.

During the summer, most rainfall is used up by trees and plants for growth or is lost to evaporation, which makes any further recovery in groundwater levels unlikely until the start of the next recharge period in autumn.


Hot Weather

The recent hot weather has meant more demand for water, and during a hot spell, the average amount of water each person uses each day can increase by more than 50%.

It puts pressure on our water network and the natural resource we all rely on, as more water is put into the system to meet demand.

Our 24 hours teams are working hard across our network to ensure we have enough water in our reservoirs. Learn more about what we are doing >>

But there are things you can do to help. We have more useful tips to save water and FREE water saving devices here >>
