  • If you prefer to bath, share the water, and don’t make it as full. Taking a bath could use between 80 and 150 liters of water.
  • Use low-flow showerheads, dual-flush toilet mechanisms and water-efficient washing machines.
  • Kettles should be filled with just enough water for your needs and not to the brim. This will help to reduce your electricity bill as well.
