Diagnóstico de patologias nas instalações hidrossanitárias prediais de uma edificação multifamiliar no município de Guarapuava – PR

Abstract

Hydrosanitary facilities are responsible for conducting the water used in a commercial or residential unit, providing health and hygiene conditions for users. Many researchers claim that pathological manifestations in these installations are recurrent and concentrate most of the failures of the different systems that make up a building. This work aims to identify the possible pathological manifestations in hydrosanitary installations of cold water, sewage and rainwater, to infer their causes and effects, in addition to proposing solutions, classifying them in a priority degree of intervention priority. More and more studies on hydrosanitary systems are needed to understand the causes of failures in order to avoid future incidences in new buildings. This work was carried out in a multifamily building with 5 floors in the city of Guarapuava - PR. Through interviews with residents of 14 housing units in this building, data on failures in the facilities were collected. The photographic record of the failures was made when possible, with authorization, in addition to the application of an online questionnaire for users to expose the information of the hydrosanitary installations of their residences. From the pathological manifestations found, it was possible to observe eight different types of manifestations, totaling 23 occurrences in the building. The sanitary sewage system concentrates the highest number of occurrences of failures, followed by the cold water and rainwater system. The most recurrent type of pathological manifestation were failures involving leaks, both in the cold-water system and in the sanitary sewer system. The classification of pathological manifestations into systems, causes, effects, control measures, severity indices, cost and intervention, allows inferring the priority of intervention of the types of pathologies found, in order to solve them and predict the appearance in new enterprises. Most pathological manifestations were classified with a low degree of severity, indicating slight deterioration, however the classification related to maintenance cost was considered high, as they involve breakages and replacement of components. Still, in relation to the difficulty of intervention, most pathological manifestations have a difficult or very difficult degree of intervention, since it is necessary to affect more than one hydrosanitary system to solve it.
