In recent years, the sanitation of the city of Lubumbashi has been a hot topic. Indeed, the city has become more and more unsanitary. There are all kinds of landfills here and there that pollute the city. The presence of waste and garbage in inappropriate places makes the city lose all of its beauty. In a process of sanitation, it is important to question the role that communication plays as an instrument of public policy, it is the object of this reflection. Also, why does the city still remain unsanitary despite all the communications made by the urban authority on the issue? The communication of organizations within a public establishment such as the City of Lubumbashi constitutes an important pillar of public policies. It must allow exchanges as well as the sharing of data and information of public utility in order to maintain a certain link at the level of society. To be effective, it must lead to adherence to the authority's message aimed at cleaning up the environment through sustained and inclusive awareness.

The content analysis of the audiovisual programs shows to what extent the journalism practiced at RTNC Haut-Katanga is stalling, because of its editorial line on the one hand, and the building effect on the other. Indeed, the objective pursued in this reflection is to demonstrate the limits of journalism which is practiced in the provinces in an audiovisual channel of the Congolese State. This journalism observes and promotes with commitment its editorial line which, moreover, constitutes one in the journalist's work. But in the case of the RTNC, this editorial line ultimately becomes a brake on the dissemination of quality information. Of course, observing an editorial line is a journalist's duty. The editorial line orients and specifies the work of a press house. However, promoting a brand image of a company, even of the state, always boils down to activism to the point where it becomes difficult to see the loopholes. The consequence is that this way of working stifles criticism. Moreover, trying to spare the boss who is the State at all costs (building effect) this stifles the work of the journalist with the risk of losing all credibility with his audience. This article has the merit of demonstrating how the editorial line, although of value in the treatment of information, ultimately constitutes an obstacle to the dissemination of information that is expected by the public. In order to avoid this inconvenience, the journalist obliges himself to respect the facts as well as his independence. He must ensure that he performs his work in accordance with the rules of the art.
