The invention relates to a process for the preparation and delivery of ozonated water to at least one user point, according to which a storage buffer tank is provided for the ozonated water, and an upstream ozonation loop is provided, making it possible to feed the tank with ozonated water, the upstream ozonation loop comprising a component for controling the flow of water flowing in the loop. A fresh-water supply line is also provided, connected by its downstream part to the upstream ozonation loop and fitted with a component for interrupting the freshwater flow, the loop portion located between the tank and the connection point of the fresh-water supply line being fitted with a component for interrupting the recirculation flow upstream of the tank.According to the invention, the tank fill level is controlled between a low level N1 and a high level Nh using said component for controling the flow of water flowing in the ozonation loop, one or other of said component for interrupting the fresh-water input and said component for interrupting the recirculation flow upstream of the tank being always open while the other of said components is closed.
