Isla Urbana ISLA urbana is a rainwater harvesting project in Mexico City

Isla Urbana has designed an environmentally, socially, and economically sustainable rainwater harvesting system that collects and cleans rainwater for households, schools and health clinics.
The system is inexpensive, easy to install and provides individual residences with about 40% of their water supply. Implemented on a large scale throughout Mexico City, this simple technology could provide 30% of the city’s water and could help give a sustainable source of water to the 12 million Mexicans with no access to clean water.
