About This Site

Using the service

www.hsy.fi is a network service maintained by the Helsinki Region Environmental Services Authority (HSY). The online service is published in Finnish, Swedish and English. There are shorter versions of the Finnish pages in Swedish and English.  We are sorry that not all content or services are available in Swedish or English and any inconvenience it may cause.

You can search for information by browsing topics or using word search. Each page has access to the search function as well as contact information and a feedback form.

The Site Print feature opens directly to the Print dialog box. When using the Print function, it only prints the main content of the page without the navigation structure.

Links on the site will open in a new browser window if the information is located on another site. You can return to HSY's site by closing the new window. To read pdf files on the site, you will need a free Acrobat Reader program that you can download from Adobe's site.
