In some places, the main criticism that residents have about data centers has to do with the amount of water they consume to cool servers. This isn’t the case in Marseille, however, which is well-supplied with this resource. The authorities have even given Digital Realty access to water from the former underground drainage channels of the Gardanne coal mines, located north of Marseille. The water flows into the port, so the firm can use it to cool its systems.
