Water quality and sanitation at the core of Blue Flag

  • The Blue Flag programme promotes sustainable development in freshwater and marine areas. It challenges local authorities and site operators to achieve high standards of water quality, environmental management, environmental education and information, safety and services. Several Blue Flag initiatives concern the monitoring of bathing water quality and safe swimming.

  • The programme aims at increasing water-use efficiency through capturing and using rainwater. Through several criteria, Blue Flag promotes water savings and clean water, minimizing the environmental footprint and promoting good cleaning and recycling practices in beaches, boats and marinas.


As the Blue Flag programme promotes the compliance with the European Directive for Waste Water Management, important improvements in the waste water treatment plants have been achieved in Spain thanks to Blue Flag.


In Slovenia, Blue Flag has had a crucial role in speeding up the building of the Waste Water Management system on the Slovenian Coast and in sharing the water quality data with the public. Nowadays, the achievement of SDG 6 is also helped by a solid collaboration between Blue Flag and the Slovenian Environmental Agency, which is also part of the Blue Flag national jury. A code of conduct for their boat was signed with them and several collaborations – meetings and conferences – have been initiated. Blue Flag is also part of the emergency communication plan of the Agency.
