The Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) was adopted in Helsinki in 1992 and entered into force in 1996.

The Water Convention strengthens transboundary water cooperation and measures for the ecologically-sound management and protection of transboundary surface waters and groundwaters. The Convention fosters the implementation of integrated water resources management, in particular the basin approach. The Convention’s implementation contributes to the achievement of the Millennium Development Goals and other international commitments on water, environment and sustainable development.

The Secretariat of the Water Convention is hosted by the United Nations Economic Commission for Europe (UNECE).
