In the late 1980s, the water supply system in Paris was privatized, with the management handed over to two private companies, Veolia and Suez. This move was intended to improve efficiency and reduce costs. Many citizens seemed to be in favor of the decision and expect better services.
　　　Supporters of the privatization initially argued that private companies would bring expertise and investment, leading to better services and infrastructure. They believed that competition between the companies would keep prices fair while ensuring high-quality water supply. Additionally, privatization was seen as a way to relieve the city of the financial burden of managing the water system.
　　　However, critics pointed out several issues with privatization. They argued that the promised efficiency gains did not arise and that water prices increased significantly under private management. Additionally, there were concerns about the lack of responsibility and transparency, with many feeling that water, a basic necessity, should not be controlled by profit-driven entities. As a result, the Paris city government decided to take back control of the water supply in 2010. The return to public management was seen by many as a victory for the citizens of Paris.
