Saneamento básico na região lindeira de Itaipu: uma análise sobre os dados de água e esgoto com base na evolução histórica de 2012 a 2022

Abstract

Access to basic sanitation is extremely important for the development of a region and improvements in health indicators. Therefore, this work is dedicated to analyzing secondary data regarding basic sanitation in the region bordering Lake Itaipu, based on data collected from websites such as the National Sanitation Information System (SNIS), the Paraná Institute for Economic and Social Development (IPARDES), and the Water and Sanitation Institute (IAS). These data were statistically analyzed to examine the historical evolution, from 2012 to 2022, of access to basic sanitation in the region, particularly regarding public water supply systems and sewage collection and treatment systems. The analysis of development during this period was compared to the possibility of achieving the goals of universal access to water (99%) and sewage (90%) suggested by Law No. 14.026/2020. Regarding treated water, some cities, such as Terra Roxa and Marechal Cândido Rondon, have two forms of water intake: surface water and groundwater. The conclusion was that sewage collection networks are still stagnant in most cities, with 7 out of 16 cities lacking any sewage treatment and collection network, and only 2 cities exceeding the 90% target.
