The United Nations World Water Day takes place on 22 March 2021 under the motto "Valuing water". In Zurich, a self-guided tour provides amazing water knowledge.

Guided by the free app Actionbound, you set off independently on a tour through the city of Zurich and discover interesting water locations. Along the way, you will have the opportunity to collect valuable hydrological data with the CrowdWater app. The CrowdWater project is presented at the Science Exploratorium of the University of Zurich. This project aims to involve the public in the observation of hydrological variables to overcome the scarcity of data in hydrology.
