Save Water

The water in the aquifers (porous rock where groundwater is stored) that we use to supply your water is below average.

This is important as 60% of the water we supply to you comes from these underground sources. Aquifers only usually fill up from rainfall during autumn and winter when there is less plant growth and evaporation.

Try these tips to help you save water


In the Bathroom

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

  • 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.


In the Kitchen

  • Save water and electricity by only boiling enough water for your immediate use

  • Use a bowl to wash dishes or vegetables

  • Fix dripping taps and you could save over 5,500 litres of water a year. If you need to find an approved plumber visit

  • If you are buying a new appliance look at the Eco-label for water and energy consumption

  • Only run your washing machine and dishwasher with a full load – this uses less water than two half loads.


In the Garden

Here are some more top tips to help you become a water efficient gardener:


  • Hang up your hose – this uses as much water in an hour as the average family of 4 uses in a day and a half

  • Water your plants using a watering can, either early in the morning or during the evening when it is cooler and there is less chance of water evaporating

  • A water butt is a great way to collect rainwater, you can use it to water your garden or wash the car

  • Wash your car with a bucket and sponge, which uses much less water than a hosepipe.



  • Cut the grass slightly longer in dry periods to allow the dew to be trapped. Leave the lawn cuttings on the lawn – it will naturally return moisture and nutrients to the soil

  • Reset your lawn mower blades to 4cm to encourage dense bushy growth.



  • Choose plants that thrive in dry conditions, such as Alyssum, Geraniums, cornflowers French and African Marigolds, Petunias, Aquilegia, Campanula and Heuchera lavender.

  • Look for the full sun symbol on the plant labels when buying new plants as this indicates their tolerance to dry conditions.

  • Move containers, hanging baskets and pots into shady areas where possible

  • If you’re potting up or planting containers, use ones made from plastic, glazed terracotta or wood. These tend to lose less water than bare terracotta

  • When potting up your planters use a small amount of gel crystals. They absorb water and can help retain the moisture in the soil

  • Bury a short length of pipe into your pot; if you water into the tube the water goes directly to the roots where the plant needs it most

  • Use mulches like bark chips or gravel to retain moisture and keep weeds down.
