Cerro Verde is a settlement of roughly 30,000 people spread across hillsides above Lima, Peru, where running water is scarce and often unsafe. The film follows the Safe Agua Peru project, a partnership between Art Center College of Design's Designmatters program and the Latin American NGO Un Techo para mi Pais through its Innovation Center, as students work directly with families in the slum to design water solutions suited to the terrain and the constraints of daily life there. Cameras show the co-creation process on the ground: students sitting with residents, testing prototypes, adjusting designs based on what families say they actually need rather than what looks good on paper. The film treats design as a practical negotiation rather than a finished product handed down from outside, tracking how ideas change once they meet the reality of steep hillsides, limited infrastructure, and household routines. It is a small-scale case study in what cross-border collaboration between a design school and a grassroots NGO looks like when the goal is clean water rather than an award.
