Tips for water use

A resident in the Helsinki metropolitan area uses an average of 139 litres of water per day. About 45% of the water used in households goes to washing. 15 % of the water is flushed down the toilet. In addition, water is used in the kitchen and to do laundry.

​The production of clean and warm water and the treatment of wastewater consume energy and chemicals. Although there is generally no shortage of tap water in Finland, moderate water use is part of a sustainable lifestyle.

Monitor water consumption

It is a good idea to monitor the water meter of your home regularly. If consumption rises from normal levels, it may indicate a water leak. A water leak can also be detected by the fact that the water meter is rotating even though no one is using water at that time.

Have leaking water fixtures repaired

Leaking taps and toilets should be repaired immediately. A seemingly insignificant, dripping leak can become costly in the long run. A dripping tap may cost you more than 100 euros and a leaking toilet bowl over 800 euros a year.

Leaking of water fixtures is usually due to aged and hardened sealing materials. You should call a maintenance worker to replace them.

Monitor the condition of piping

The condition of water pipes should also be monitored regularly to prevent major water damage. It is possible to receive compensation for a hidden water pipe leak on the property on your water bill. For more detailed instructions, see the instructions for leak compensation.

Use the right dose of detergent

The tap water in our area is soft, which means that its lime content is low.  This is why less detergent can be used than with hard water.

Measure out the detergent based on the instructions for soft water. You do not need to use water softener or softening salts for washing machines.

In the Helsinki metropolitan area, the hardness of water ranges from 2.7 to 4.5 °dH, depending on the plant.

Degree of water hardness

  • Very soft = 0–2 °dH
  • Soft = 2–5 °dH
  • Medium hard = 5–10 °dH
  • Hard = 10–21 °dH

Use water reasonably

  • Favour short showers. Close the tap while lathering soap.
  • Wash full loads of laundry and dishes.
  • Use the eco and half-load cycles of washing machines. This also saves electricity.
  • Favour water-saving options when purchasing new household appliances and water fixtures.
  • Use a plug in the sink if you wash your dishes by hand. Avoid rinsing dishes under running water.
  • Use rainwater to water your garden and lawn.
