Ways to save water

General savings (Nielsen and Dyck-Madsen 2005)

  • Use less water when bathing. Install a single lever thermostat. Supplement with a water-saving showerhead. This will save app. 6-12 liters per minute, and saving hot water saves energy.

  • Choose a single lever tap. By installing taps with only one lever, you use less water than if there are two.

  • Turn off your water immediately after use. An open faucet releases up to 16 liters of water per minute. Remember to turn the faucet off when washing dishes, peeling potatoes or brushing your teeth.

  • By choosing a water-saving toilet with 3/6 liter flushing or 2/4 liter flushing you can save between 6-9 liters of water with each flush.

  • You don't need to rinse plates before setting them in the dishwasher. It is sufficient to scrape off food remnants prior to placing them in the dishwasher.

  • Fill the dishwasher and washing machine fully before starting them. This saves time, reduces wear and tear on the machines and reduces wter and electricity consumption. Many new washing programs automatically regulated the amount of water and electricity based on the weight of the clothes. Low-energy programs reduces the amount of water consumed.

  • Be aware if the toilet continues to flush. Even the slightest amount of continual flushing can waste a lot of water and cost a lot of money.

  • If you have an older toilet, consider exchanging it for a dual flush water saving system.

  • A tap or WC that slowly drips water loses app. 20 liters/day (7.3 cubic metres/year); a fast drip loses 100 liters/day (37 cubic meters/year); a small stream (1.5 mm) loses 180 liters/day (140 cubic meters/year). If a cubic meter of water costs 50 DKK, this last figure equals 7,000 DKK.

  • A water-saving showerhead uses 6-9 l/min, while an ordinary showerhead uses app. 15-20 l/min. If you do not wish to exchange the whole showerhead, you can purchase a flow restrictor kit at your local plumber or hardwarestore, which reduces the flow of water through faucets and showers. For ordinary faucets, you can also buy small aerators, which add air to running water and reduce daily water consumption.

  • An ordinary faucet releases up to 20 liters of water each minute.

  • Even with a water-saving showerhead you can save 18 liers of water by getting out of the shower 2 minutes earlier.

  • You use app. 35 liters of water in a 3-minute shower. A bath in a bathtub uses app. 80-100 liters of water.

  • The heating element in a hot-tub uses app. 2.7-6 kW. Hot-tubs usually have a minimum consumption of 180-330 liters of water.

  • A hole in a water hose the size of a pin can lose up to 70 liters a day.
