Goal 6: Clean water and sanitation

Ensure availability and sustainable management of water and sanitation for all

Observations and information on the hydrological cycle, including wetlands, aquifers, lakes, reservoirs and rainfall, are vital for guiding sustainable water management. The data and analyses provided by National Meteorological and Hydrological Services and other service providers also help to ensure that drinking water is safe and that human activities do not pollute aquatic ecosystems. Their work is supported by the World Hydrological Cycle Observing System (WHYCOS), which is improving basic observations, strengthening international cooperation, and promoting the free exchange of data in the field of hydrology.
