Influência da verticalização de condomínios no abastecimento de água e na coleta de esgoto: um estudo de caso em Presidente Prudente

Abstract

The increasing verticalization of cities is a phenomenon observed in various localities around the world, directly impacting urban basic sanitation infrastructure. In Presidente Prudente, this trend has raised significant concerns regarding the capacity of water supply and sewage systems to support the increased demand generated by new high-rise buildings. The primary objective of this study is to analyze the repercussions of the growth of vertical buildings on water supply and sewage systems in Presidente Prudente. Data from the 2022 IBGE Demographic Census, the National Sanitation Information System (SNIS), and Sabesp were collected and standardized into a Microsoft Excel spreadsheet. This allowed for the correlation of population growth with the increase in water connections and consumption. The spreadsheet was then used to feed the QGIS program to generate thematic maps highlighting condominiums and consumption ranges. The research revealed a demographic and urban transformation with a population growth of 8.7% between 2010 and 2022. Simultaneously, water connections increased by 25.36%, and residential economies grew by 30.26%. A total of 724 condominiums were analyzed, divided into 195 horizontal and 529 vertical. The analysis of vertical condominiums, especially in the range of 201 to 500 economies, showed that since 2010, seven new locations with 2,329 economies have emerged, resulting in an average of 333 economies per connection. These data indicate a transformation in the urban dynamics of Presidente Prudente, characterized by faster growth of vertical developments compared to the population increase. This phenomenon results in a decrease in the average number of inhabitants per property, and this family subdivision changes the demand for sanitation services. These findings highlight the need for adjustments in urban planning and sanitation policies, considering changes in housing and family dynamics.
