World Water Week – August 24-28, 2025

World Water Week occurs late August or early September every year. This year, it takes place from August 24 to August 28. There are very few things in the world as relevant to life as water and this event is geared at showing us the benefits that come with this satisfying chemical composition. It is an enlightening conference organized annually by the Stockholm International Water Institute (SIWI) and is themed on different concepts, each addressing a wide range of the world’s water development and sustainability issues.

History of World Water Week

Water is essential for human existence and life in general. This inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms.

The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in that it is the only planet known to have oceans of liquid water on its surface.

Water also plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing is a major source of food for many parts of the world. Much of the long-distance trade of commodities is transported by boats through various bodies of water. Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Water is an excellent solvent for a wide variety of substances both mineral and organic; as such it is widely used in industrial processes, and in cooking and washing

In reverence to practically the most important resource to human existence, World Water Week in Stockholm originally began as the Stockholm Water Symposium in 1991 and has been convened annually ever since. A different theme is selected each year, ultimately geared at tackling the world’s greatest challenges, such as the climate crisis, poverty, and the loss of biodiversity.
