Our Water Resources

 Last Update: 14 January 2019


Wet December improves soil moisture, but water resource levels remain below average

The dry summer and below average rainfall at the start of this winter has led to relatively dry soils, which made it less likely for rainfall to reach the aquifer and caused a delayed start to the recharge period.

The wet weather in December has resulted in more moisture in the soil, which means that rainfall from now has a greater chance to soak through to the aquifers below.

Our water resources remain below average, but at an improved position to this time last year. We are dependent on significant winter rainfall to ensure that our water resources are in a good position for the spring and summer, and we are continuing to plan to ensure we are prepared for a range of different rainfall scenarios over this winter.

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
