Our Water Resources

 Last Update: 21 September 2018


Water resources remain stable following one of the driest summers on record

Our water resources remain stable, although at below average levels, following one of the driest June and July periods on record. The summer ended with above average rainfall in August and the demand for water returning to the seasonal average.

Looking ahead, we will soon enter the important recharge season when we typically see a recharge of our aquifers, if there is sufficient winter rainfall. This period usually runs from October to March, although the catchments in our areas have very dry soils at present. This will mean a delay to the start of the recharge period this year, as it will take longer for rainfall to soak through to the aquifers below.

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
