Our Water Resources

 Last Update: 17 May 2019

April rainfall well below average and water resources remain below average

All our regions received very low rainfall in April, and groundwater levels have started to decline.

Overall this winter, rainfall was below average. We are now heading into the spring and summer months and any further recovery of groundwater levels is unlikely. This is because groundwater is more likely to be replenished from rainfall during autumn and winter, when there is less plant growth and evaporation. October to March is the critical recharge period when rainfall is expected to reach the aquifers (porous rock where groundwater is stored), which are used for 60% of our supplies.

Whatever the weather brings, we have plans in place for a range of different rainfall scenarios over the next year and will continue to work with customers to help save water.

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
