Costa Rica is a small country in Central America with a population of around 5 million people and wide availability of water and biodiversity. Costa Rica can be subdivided into three main regions: the central region characterized by its high volcanoes and temperate climate, the Caribbean characterized by its high rainfall and the Pacific region characterized by a drier climate. Therefore, despite having a relatively small territory, its diversity of reliefs and ecosystems generate certain challenges in water management.
Household surveys provide us with representative data of the entire population, validated by statistical institutes and that allow cross-checking with other social statistics such as area, income, and gender. The 2020 National Household Survey was applied to 8,124 representative households and collects some data on water in their household surveys in accordance with the WHO / UNICEF guidelines, including the fact that it is one of two surveys in the region that asks on the treatment of septic tanks. However, the survey does not provide metrics to estimate non-piped improved water sources, as well as improved latrines, making it difficult to accurately estimate SDGs 6.1 and 6.2.
