Problems with the water, water supply or water meter

The reliability of the water supply network in the Helsinki metropolitan area is very good. Sometimes, however, we have to cut off the water supply due to either sudden disturbances or planned maintenance work. See below for instructions on what to do in the event of various disturbances.

A warm welcome to you from water services!

Reasonable water and sewer use

More than 40% of the water used in households goes to washing. Additionally, flushing the toilet, dining and laundry make up a significant part of the daily water consumption. Do you know the sewer etiquette? Use the sewer and toilet bowl only for their intended purpose. Sort waste into the correct waste containers.​​​​

Water rates

Water rates enable the supply of high-quality drinking water to the more than one million residents of the Helsinki metropolitan area, and the efficient treatment of wastewater to protect the Baltic Sea. We cover all the costs of water services with the rates charged for water and connection to the network.

How the water supply works

When you open the tap, you are at the same time opening a path for water from our water treatment plants to you through the water pipes. Once you have used the water, it ends up at our wastewater treatment plants through the sewers. To ensure the water’s path, we are continuously building and maintaining our water networks. This allows us to secure uninterrupted water supply services for more than one million residents.
