Agua means Water both in Spanish and Portuguese. It comes from the Latin 'Acqua'. The Agua Project has a very important mission, which is to help disseminate education about Water all over Latin America. My company had the honor to make a small contribution towards this mission, and Drupal has helped us in creating the website for the project.
For more information about the project, please read:
Itaipu, the world's largest generator of renewable clean energy, is a big advocate of FOSS, and they use Drupal in many of their projects.
Itaipu promotes several initiatives around 5 themes: Energy, Environment, Social Responsibility, Tourism, and Technology. The Agua Project is an Environmental initiative to promote knowledge about Water all across Latin America. The project's goal is to reach 10.000 people directly and 300.000 people indirectly by providing free courses using both traditional and distance education. These range from basic courses where children learn about the importance of water till more advanced courses where engineers learn about Dam security, for example.
