Resumo:
The New Legal Framework for Basic Sanitation in Brazil (Law No. 14.026/2020) represents a strategic opportunity to enhance energy efficiency in the sector by requiring service providers to establish goals and actions aimed at the progressive improvement of rational energy use. Given that water supply and wastewater systems are highly energy-intensive, adopting structured energy management practices is essential. In this context, this dissertation analyzes the challenges and opportunities for implementing energy management systems in the sanitation sector, based on the ABNT NBR ISO 50001:2018 standard. The study provides an overview of the sector, addressing governance, energy consumption, and the impact of current legislation. Additionally, it critically examines the ISO 50001 requirements within the sanitation context, considering aspects such as significant energy uses, performance indicators, energy baseline, and opportunities for optimization. The dissertation also discusses regulatory challenges, business models, and public policies that influence the adoption of energy management in the sector. By providing a methodological and strategic framework for implementing energy management systems, this research contributes to improving energy efficiency in sanitation companies, reducing operational costs, and advancing sustainability and service universalization goals.
