SUMMARY:

The accelerated growth of the world population, join with the increasing volume of sanitary sewage produced, and at the same time being dumped in water resources and in the soil, with or no treatment, has been contributing to the degradation of the environment and causing serious environmental and social problems. In this sense, the growing search for environmental sanitation solutions and sewage treatment technologies is a fundamental part of the process of recovering and maintaining the quality of the population life and the environment. In Pernambuco, the Ipojuca River Environmental Sanitation Program was conceived with the aim of promoting environmental sanitation in the basin of de river, based on the implementation of sanitary sewage systems, expansion of the coverage of existing systems and improvement in sewage treatment rates, with the aim of improve environmental quality and increase the availability of good quality water. This work aims to evaluate the physical-chemical and microbiological parameters of Sewage Treatment Stations (Tacaimbó, Rendeiras and Gravatá) under the analysis of multivariate statistics with application of computational tool. The analyzed parameters were provided by COMPESA, all samples were collected in the year 2020, in each months of the year. The results of the analyzes were compared to the values recommended by current environmental legislation at the federal and state levels. By analyzing the descriptive statistics, it is concluded that the ETE Rendeiras in some periods of the year presents satisfactory operation in the removal of organic matter. The other stations require adaptations in the treatment to comply with current environmental legislation. Through multivariate statistics, it was possible to conclude that the greatest variation in the data is related to the parameters that represent pollution (organic matter). This fact may either represent flaws in collection and storage procedures, or inefficient operation at certain times of the year.
