This partnership involves five secondary schools and five countries: Bulgaria, France, Germany, Italy and Sweden. The project will take place between September 2015 and June 2017. Its theme is in the sphere of the problems the contemporary world must face; such as the lack of responsibility toward future generations and the indifference to the irrational use of water supply in daily life. Water is an essential source for the survival of humanity. The project is focused on the understanding of water pollution and the preservation of water supplies at a local, regional, national, European and international level.
