ABSTRACT: Among the building services systems, the one with the potential to present pathological manifestations is the hydrosanitary system. There are several possible pathological manifestations and one of them is the contamination of drinking water in the distribution and storage system. In some situations, the water has an adequate standard of potability at the source, but in the reservoir, it is contaminated. The method adopted consisted of a bibliographic review, whose objective was to map, identify and classify the main causes of contamination of drinking water in hydrosanitary land systems in several databases. As a result, the several causes of contamination identified and classified were: cross-connection; wear of materials; storage time; maintenance; seal; equipment; project; vandalism/sabotage; inadequate treatment; and source. It can be concluded that the causes are diverse and that there are measures to be taken to avoid them, and among the recommendations it can be concluded that there is a need to implement a culture of maintenance and that the use of reservoirs requires much care to ensure the quality of water in the distribution and consumption system. Finally, the importance of a well-developed hydrosanitary systems project is emphasized and taking into account the technical recommendations.
