An efficient showerhead can save up to 20L of water a minute, or over 50,000 Litres a year for the average person! Think what the savings can be for a family. In some places that could directly save you over a $100 a year on your water bill. Low flow showerheads had a bad rep for feeling like only a trickle of water, but modern designs are much nicer and just as pleasant as traditional designs. Looks for water efficiency ratings when replacing your showerhead.
