The Water Rooms: a journey to discover, understand and change

“The Water Rooms” is an ambitious outreach project led by WWAP to be presented at EXPO 2015 - the Universal Exposition – and consists of a visionary and inspirational video-itinerary of five sequential “rooms” that will trigger interest and encourage learning about water resources and their sustainable management. Each “room” offers a fun and emotional experience inviting the viewer to reflect on the dynamics affecting the resource and the actors managing it.

The meeting taking place at WWAP premises from Wednesday 21st to Friday 23rd of January is a brainstorming and writing exercise to create the storylines for each Water Room, and it will bring together scientists and technical experts on one side and creatives, filmmakers and writers, on the other.
