Get rid of the lawn - Replace thirsty lawns with drought-resistant plants like lavender and verbena.
Take a shorter shower - Consider setting a timer to ensure you don't lose track of time.
Fit a low-flow shower head - Reduce the amount of water you use to wash without even realising.
Put a water butt under your drainpipe - Use the water collected to water your garden, wash the car, or clean the windows.
Use a watering can - A hosepipe can use as much as 1,000 litres of water an hour. A watering can wastes much less.
Install a water meter - When you can see how much you use on each bill, it is easier to reduce.
Keep a jug of tap water in the fridge - It will help you avoid running the tap until it is cold.
Only wash full loads - Wait until you have a full load to do laundry. It will reduce waste water and electricity.
Shower less often - Most of us don't get dirty at work each day, so consider skipping a day or two a week and see the water savings add up.
Don't go nuts - Be conscious of the amount of nuts you consume. Industrial farming of almonds, pistachios, and other nuts is water-intensive.
