There is sufficient legal habilitation to hand over the company that has managed the service of potable water with anteriority, the data of the users of the service related to the period of time in which this company managed it, without requiring the consent from the headlines. This habilitation exists both if the company was the responsible for the treatment of the data as if he were a person in charge of the treatment. This cession should not include other information related, for example, to incidences that have been produced later to the date in which another company took charge of the service. This without harm that, if on finishing the deferment of the intervention for which this other company loans the service of water supply, the Town Council decides to entrust again the former company the provision of the service, the communication of information can be admissible about the period in which the service has been intervened.
