One of the smallest countries of South-America, Ecuador is considered a medium-income country. At first glance, the disparity between urban and rural areas in matters of access to basic drinking water services seems to be on the decline: 100% of the urban compared to 80% of the rural population have access to a public water supply. These data, however, do not take into account the quality of the supplied drinking water, nor the continuity of the services provided. Since 1997, Join For Water has been active in underprivileged regions to improve access to drinking water and sanitation and to provide appropriate management structures. Ecuador is one of the world’s first countries to include the right to water in its constitution and Join For Water and its local partners played a distinct role in making this provision a reality.
