IDENTIFICATION AND EVALUATION OF WATER CONDITIONS SUPPLY AND SANITARY DRAINAGE IN DIFFERENT DEGREES OF VULNERABILITY IN THE MUNICIPALITY OF JOÃO PESSOA, PB.

Abstract

In recent decades, Brazil has undergone significant changes in the construction of cities and some scholars argue that these places act as mechanisms of exclusion, because the centers are endowed with infrastructure and the peripheries are characterized as a distant and subequipped space that predominantly has low income populations. These characteristics enable the risk and deprivation of adequate infrastructure that produces risks to human health, quality of life and environmental degradation, configuring in social and environmental vulnerability. The objective of this study was to identify and evaluate the conditions of sanitary sewage and water supply in different degrees of social and environmental vulnerability, through the use of Geographic Information System (GIS) of the city of João Pessoa, located in Paraíba state for the year 2010. The methodology consists of the cartographic overlap and spatialization of six variables of the 2010 IBGE’s Demographic Census, and as a result we have to relate the listed variables of water supply and sewage to the most intense socioenvironmental vulnerability classes (“High” and “Very High”), it was observed that water distribution and sewage collection are not necessarily related to areas of greater social and environmental vulnerability as the hypothesis applied to the work suggests.
