Our foundation

The first talks concerning the foundation of a European Association of Manufacturers of Water meters took place in Brussels in January 1958. It was an informal meeting between Marcel Nicaise, managing director of Contimeter SA and Paul Huysmans of EGEA SA. It was decided to organize an inaugural meeting with representatives from Belgium, France, West-Germany, Italy and Switzerland.
The first international meeting took place in Zürich on 4th March 1958. This is when the association was named AQUA. The board of representatives of the founding countries and further a technical and a commercial committee were being installed.
