For two years the team from Engineers Without Borders Colombia worked on the co-design of a community management system for water resources, with the help of professors, researchers and students from Universidad de los Andes, and high school students and teachers (between sixth and eleventh grades) from 10 schools in 9 municipalities of the Province of Guavio and Sabana Centro of the Department of Cundinamarca in Colombia. The Guavio province is of vital importance to the country, as it has water making factories in its paramo ecosystems. Therefore, it is necessary that its inhabitants have a strong environmental awareness and good management of water resources. This article presents the main lessons learned through the co-design process of a technological platform and a participation strategy that encourages the empowerment of the rural school community in the management of this resource.
