Your bathroom

Check for leaking taps. One leaking tap can waste up to 2,000 litres a month.
Install a water efficient showerhead or fit a flow-restricting valve. Showers can now use as little as 9 litres per minute instead of the old shower heads that used 22 litres per minute.
Turn taps off tightly and replace washers when they begin to leak.
Take shorter showers by using a timer.
Turn off the tap when brushing your teeth and use a plug in the basin when shaving.
Turn your single-flush toilet into a dual-flush toilet or install a displacement device in the cistern (tank) of single-flush toilets.
Check your toilet for leaks by adding drops of food colouring to the cistern. Don’t flush for one hour and if the colouring shows up in the bowl it’s leaking.
Before you go to bed, check your water metre reading then make sure no one uses any water overnight. If the reading is higher in the morning, you have a leak.
Install water efficient taps or tap aerators to cut water usage.
