UWAD Chile

Atacama Desert in Chile is the driest desert in the world. Antofagasta is the biggest city in this area, with the lowest rate of Urban Green Spaces (UGS) in Chile: 6 times less than the minimum recommended by the World Health Organization: 9 m2 per inhabitant. This index affects the health condition of the population, from both a psychological and physical perspective. On the other hand, 90% of the Antofagasta inhabitants have no or scarce access to the UGS. This phenomenon contributes to inequality and social unbalance. In many ways, this area suffers from the extreme environments, as drought and water scarcity. All drinking water is produced by desalination of seawater. In the North of Chile, the main factor to improve Urban Green Spaces (UGS) is the access to the water

From Grey to Green

This project is about recycling treated gray water from buildings to the establishment of green urban infrastructure and capacity building of urban communities. Greywater is a renewable source because people use water every day. Today, that resource is lost and led back into the sewerage system. Our project will integrate a source separation system of grey and black water coming from households or public buildings, and recycle 100% of the grey water. We can recover 100L greywater per person every day, and purify it using Scandinavian water technology, and reach the minimum standard (UGS) of health recommended by WHO. By implementing that resource in our planning of cities in extreme environments and drought, we can design for future green areas and urban biodiversity in the habitat of the desert.Partners:
