Colombia is an Andean country located in the north of South America with coasts in the Pacific Ocean and in the Caribbean Sea and large reserves of fresh water. Its great heterogeneity in climates, terrain, altitudes and cultures creates challenges in the provision of water and sanitation.
A rich source of information for measuring the current state of access to water and sanitation are household surveys. Throughout Latin America and the Carribean, household surveys provide us with representative data of the countries' population, validated by statistical institutes, which allow cross-checking with other social statistics such as area, income, and gender breakdowns.
This page relies heavily on Colombia's 2020 Large Integrated Household Survey, which surveyed 57,265 representative households. The 2020 Large Integrated Household Survey does not collect water and sanitation data according to WHO / UNICEF standards, which makes it difficult to obtain timely information on the matter. Specifically, Colombia does not distinguish between piped water to the home and the field or between types of improved and non-improved latrines.
