Suez S.A., known from 1997 to 2001 as Suez-Lyonnaise des eaux, was a leading French multinational corporation headquartered in the 8th arrondissement of Paris, with operations primarily in water, electricity and natural gas supply, and waste management. Suez was the result of a 1997 merger between the Compagnie de Suez and Lyonnaise des Eaux [fr], a leading French water company. In the early 2000s Suez also owned some media and telecommunications assets, but later divested them. According to the Masons Water Yearbook 2004/5, Suez served 117.4 million people around the world. The company conducted a merger of equals with fellow utility company Gaz de France on 22 July 2008 to form GDF Suez (called Engie since 2015). The water and waste assets of Suez were spun off into a separate publicly traded company, Suez Environnement.
