Közkutak is a mobile application for users to report and monitor drinking fountains, and to find out which one is available in their area. 

In addition, the application contains a list of drinking fountains, along with details such as location, opening and closing times, and the number of people who can use it.

Közkutak is a project of the Budapest Water Treatment Plant. The application collects information on the location of drinking fountains that have been marked in the city, as well as their status. The data is used to plan the infrastructure of the water supply network and to provide information to the public.
