Turning off the tap when you don’t need it is a great way to conserve water and a great way to help the Earth. You can save up to 15 Litres of water (4 Gallons) each time you brush your teeth, if you turn off the tap! This amounts to 30 Litres a day, which amounts to around 900 litres a month! Thats enough water to fill 1800 half-litre water bottles!!! That’s a lot of water that you could save, and it’s all by turning off the tap when brushing your teeth.
