Our Water Resources

 Last Update: 25 October 2018


Water resources stable as the recharge season begins

Our water resources are currently below average, but at an improved position to this time last year.

Our recharge season runs from October to March, if there is enough winter rainfall, we expect to see recharge of our aquifers.

October rainfall was below average and soils are drier than average after the long hot summer. This has meant that the amount of rain reaching aquifers has been below average so far this winter.

We are depending on good rainfall over the winter for our water resources to be in a good position for next year.

Whatever the weather, we ask our customers to save water where possible. This is good for the environment and can also help customers save energy and money.

Keep track of the tap

  • Shorten your shower – take a 4-minute shower instead of a bath – you will save around 50 litres

  • Keep track of the tap logo

  • Don’t overfill the bath – if you do fancy a bath try and use less water in it – it is easy to save over 30 litres each time

  • Turn off the tap while brushing your teeth, and save over 6,500 litres of water a year and encourage others in your household to do the same

  • Whenever you can, use the half flush button if you have a dual flush toilet

  • A cistern displacement device can save one litre per flush, saving up to 5,000 litres a year
