A billboard that refreshes parts other billboards cannot reach

The first billboard ever to create drinking water from humidity in the air has produced 15,000 litres of water in six months.

Launched at the end of 2012, the billboard is now a prominent feature of the skyline in Bujama, a small village just south of Peru’s capital city, Lima. The climate is oppressive, with some residents of Bujama having no access to a clean water supply. Since the billboard’s arrival, residents of Bujama now have access to an average of 96 litres of drinking water a day.

The unique billboard was co-produced by outdoor advertising owner Clear Channel Peru and researchers at UTEC, University of Engineering and Technology in Lima. Media agency Media Connection BPN and advertising agency, Mayo Draft FCB Perú, have also been full partners in the project.

The billboard cost $32,600 to set-up and works by using a panel to trap humidity in the air, transforming it into water. Internally, the panel consists of five devices that extract water vapour from the air using a condenser and filters.

The water is stored in tanks at the top of the structure, and then filtered before flowing down a pipe to a tap that is accessible to all who walk past. On average, 15 to 18 families arrive at the billboard to access the water every day.
