Consequently, the City Council of Paris voted the construction of a new pumping station to replace the previous one with newer technology.

The station (named station A) consisted of two buildings, the engine room and boiler room, both characterized by a brick structure and large roofs topped by skylights to allow sufficient ventilation and lighting.

So at the end of the First World War a new project was launched to attach a new pump to the previous one, referred to as station B, which was electrically powered.

In 1955, station A was dismantled and the engine room became primarily used as a garage, and then as an office for administrative services until 2007, when the Pavillon de l'eau was inaugurated.

Since the beginning of our times, when Paris was still called Lutetia, the city has experienced four different periods of production and distribution of water.
