World Water Day celebrates water and raises awareness of the 2 billion people currently living without access to safe water, and is celebrated every year on March 22. The idea for this international day dates back to 1992, when the United Nations Conference on Environment and Development was held in Rio de Janeiro. In the same year, the United Nations General Assembly adopted a resolution declaring March 22 World Water Day. This day has been celebrated since 1993, and every year messages and publications about World Water Day reach millions of people through social networks, websites and other channels. The theme of this year's World Water Day is Groundwater - making the invisible visible.
Groundwater is invisible, but its impact is visible everywhere because almost all liquid fresh water in the world is groundwater, and as climate change worsens, groundwater quality is becoming increasingly critical. Groundwater must be protected from pollution and used in a sustainable way, balancing the needs of humans and the planet. The vital role of groundwater in water and sanitation systems, agriculture, industry, ecosystems and adaptation to climate change must be reflected in the creation of sustainable development policy.
In addition to capacity developmeent and advocating for the improvement of the water services sector, ie water supply and wastewater collection and treatment services in Bosnia and Herzegovina, but also in Southeast Europe, the Aquasan Network in BiH contributes by raising awareness on all key water issues. In this way, the Aquasan network in BiH continues to be built as a knowledge center that transfers its experience and knowledge to others and contributes to the overall improvement of the water services sector.
