Text messages regarding water supply cuts

It is sometimes necessary to cut off the water supply as we maintain the reliability of the water network. We give notice of water supply cuts in advance so that you can be prepared.

There are approximately 500 anticipated water supply breaks in our service area each year. Sometimes we also send text messages in the event of sudden disturbances.

We automatically send text messages to residents over the age of 16 in the Helsinki metropolitan area whose phone number and address are public. Please note that we cannot obtain the address from the carrier even if the phone number is public if the address cannot be found, for example, through directory assistance services.

Register your number if

  • your phone subscription is registered to a place other than your residence (e.g. work phone);
  • you have prohibited your carrier from disclosing your address; or
  • your phone subscription is unlisted or prepaid.

Privacy protection

Our contract customers are properties and housing companies, such as apartment buildings and terraced houses, so we only have the contact information of the owner, property manager, etc. We do not use the HSY customer register to collect numbers.

We do not use the numbers stored in the system for anything other than giving notice of water supply cuts. The numbers are not sold or passed on, and they are stored by us on a password-protected server that can only be accessed by people operating the text message system.
