IDDI understands that one of the most pressing problems affecting low-income populations in both the Dominican Republic and Haiti is the lack of access to clean water. Many diseases are preventable simply by supplying clean water. As a result, for many years, IDDI has carried out a water and environmental sanitation campaign in multiple communities, including the construction of aqueducts to increase the coverage of effective and sustainable drinking water and sanitation services in rural communities, improving access to drinking water accompanied by training programs in the management, local self-management, and maintenance of water systems. It also includes improving sanitation through the installation of micro-sanitation systems in communities, environmental sanitation improvement infrastructure projects (pedestrian walkways, clearing and cleaning of ravines), urban solid waste management through the creation and strengthening of community solid waste collection enterprises, and educating and raising awareness among the population about the importance of water.
