The increasing pollution of water resources and the environmental challenges related to their availability reinforce the urgent need to adopt sustainable practices, such as reuse, to ensure water security and sustainability. In this context, this study aimed to analyze and establish criteria to guide the evaluation and decision-making process for the implementation of water reuse projects for industrial purposes in sewage treatment plants, based on integrated river basin management.The study was based on an analysis of the Joanes River Basin, located in the Salvador Metropolitan Region (RMS) within the Recôncavo Norte and Inhambupe Water Planning and Management Region (RPGA). The basin was selected for its water resource availability, industrial growth, water-related economic activities, and regional importance for supply and socioeconomic development. The methodology included eight stages, including a literature review, area characterization, mapping and classification of WWTPs, availability and demand analysis, pilot project definition, georeferencing, industry-WWTP distance analysis, pilot project structuring, and potential risk assessment. The results indicated high reuse potential, capable of meeting more than 100% of industrial demand in almost all sections of the basins representing a strategic opportunity for rational water use. The mapped potential risks allowed for an integrated approach to reuse, assessing its impacts on project viability and establishing controls to ensure greater acceptance, operational efficiency, and sustainability of the reuse system.The analysis of the distance between the Pilot WWTP and users, combined with the economic evaluation, demonstrated that, despite its infeasibility on a small scale, the study was essential for testing the technical and economic viability of reuse, applying the defined premises and criteria in practice. Thus, the product of this master's research resulted in a robust evaluation protocol, serving as a technical instrument and guiding document for the systematic assessment of the feasibility of implementing water reuse projects in WWTPs, highlighting the study's relevance for sustainable water management strategies and its potential for replication in other river basins.

Santos, Edison Ribeiro dos Garrido, Raymundo José Santos The reality of the contemporary aquatic environment is expressed by the intense pressure that all surface water sources and aquifers, especially continental ones, are suffering due to the intensive multiple uses of water. The National Water Resources Policy (PNRH) enshrined in Law No. 9,433/1997, conceives water as a water resource and implements the Charge for the Use of Water Resources as a management instrument. This study was conducted in the basin of the Verde and Jacaré rivers, one of the 34 sub-basins that make up the São Francisco River Basin, inserted in the semi-arid region of Bahia, in the physiographic regions of the Sub-middle São Francisco River, a semi-arid region, whose scarcity of Water is a reality, which can be worsened by the increase in population and the different uses of water. It has a methodological basis in Bibliographic Research, which allows us to know what has already been studied on the subject and relies on the author's life experience in the study region. The general objective of this work is to evaluate the feasibility of charging for the use of water resources in the Verde and Jacaré river basins as a means of ensuring the socioeconomic development of the basin region, taking the São Francisco River basin as a reference. The specific objectives consist of evaluating possible associations with other sub-basins of the São Francisco that create a level of revenue through collection that is capable of accommodating fixed costs, even with the aggregation of the Grande and Corrente rivers; a possible adhesion of Verde and Jacaré to the São Francisco Main Channel Committee; membership to a single agency in the state of Bahia or to an agency that covers the region where Verde and Jacaré are located, possibly joining the committees of the Grande and Corrente rivers, making up a single agency and which they would receive, through membership for purposes exclusive to collection, the Verde and Jacaré basins. In stage 1, the Water Planning and Management Region – RPGA is detailed and the simulation of charging in the Verde and Jacaré river basin and its revenue potential is analyzed. In stage 2, the estimated revenue, and investments and/or actions to be implemented in RPGA-XVIII are evaluated, according to the potential flows that this basin demands. The assessment shows that there is no financial sustainability for the creation of the RPGA Basin Agency for the Verde and Jacaré rivers; In developing this research, its author focused on the experience of charging in the São Francisco basin, considered a central reference to honor the principle of hydrographic unity; recommends that the state's water management body, INEMA, carry out feasibility studies to implement the charge and create an agency with the committees of the tributary sub-basins of the São Francisco. As a final specific objective, the net benefit for society in the basin is calculated in the case in which the revenue from the collection is allocated entirely to sanitation.

The integration between policies that promote water resources management, basic sanitation and environmental education contributes to citizen education, enabling individuals to understand their crucial role in advancing sustainability. In this context, the objective of this work was to analyze the potential for strategic dissemination of the interrelations between water resources management, basic sanitation and environmental education through the Express Sanitation Program - PSE. To this end, a literature review, the diagnosis of the actions carried out by the PSE and, finally, the structuring and application of evaluation models were used. An evaluation mechanism and indicators that will enable its use in similar actions and projects in other regional and national contexts were also proposed. Finally, it was concluded with the delivery of two evaluative models in the form of forms and a matrix of indicators containing 20 (twenty) indicators distributed in 4 (four) dimensions. In addition, it was also possible to define priority areas of action of the PSE program based on the information obtained through the National Sanitation Information System - SNIS. Thus, the methodological protocol proposed and delivered as a product of this master's degree, aims at the application and use of them by DESO through the PSE, which consists of an important initiative for the dissemination of knowledge and integration of management, having been awarded for three years with the SDG Seal for the fulfillment of SDG 6, SDG 4 and SDG 17, of the United Nations 2030 Agenda.

Santos, Juliana dos Ferreira, Adriana Costa The supply of quality fresh water has become the most important natural resource in this decade. Agricultural expansion and the large-scale food production model have made Brazil one of the world's biggest consumers of pesticides and also one of the countries that tolerates the presence of these substances in water the most, without there being an efficient dissemination system on the subject. In this context, Information and Communication Technologies can be an ally in scientific dissemination. Apps for smartphones are a method that has not yet been explored in the field of water resources, especially those aimed at guaranteeing access to information on the quality of drinking water. In this sense, the aim of this work was to develop a mobile application for Android, as a Minimum Viable Product (MVP), with data on the parameters of pesticides in drinking water offered by Brazilian Water Supply Networks and made available by the National Program for Surveillance of Water Quality for Human Consumption (VIGIAGUA). The app also has five other functions: Consultation of Legislation on Pesticides, Rapid River Assessment Protocol (PAR), Contacts for Toxicological Assistance Centers and Contact Centers for the Return of Used Pesticide Packaging. The study was divided into two parts: the first was a survey of the literature on pesticides in drinking water and the second was the development of the application using the free, open-access software Mit App Inventor. The results presented demonstrate the viability of the App developed as an aid to scientific dissemination, especially in terms of popularizing access to data on water monitoring from the Information System for the Surveillance of Water Quality for Human Consumption (SISAGUA), as well as the chance to identify some of VIGIAGUA's shortcomings, thus being able to make recommendations for improvements to it, while delivering a new technological tool to society, with the prospect that this Application can be improved in new studies.
