Reporting the water meter reading

Sign in to the Service From the Consumption Web link. The service allows you to enter water consumption readings, browse your property's water consumption history, and provide feedback or send questions.

The ID is the consumption point number (from the water bill or reading request). The password is the meter number, which can be found on the notification card and water bill (the meter number on the water meter may not be used).

When saving the meter reading, you may receive an error message. If the message deviates significantly from your annual consumption estimate, we recommend contacting the water billing department to check the consumption estimate, office secretary Miia Räihä, tel. 050 3753 930.
