Low-flow showerheads can reduce how much water you use for showering by 20 to 50%. A low-flow showerhead can save up more than 50 liters per day. Replacing all your showerheads with low-flow models can save hundreds of liters per day. Inserting an aerator (watersaver) is a simple and inexpensive way to reduce the water flow from a showerhead by 25 to 50%. Try to limit showers to no more than 5 minutes.
