Water resources management is a key element of Brazil’s strategy to promote sustainable growth and a more equitable and inclusive society. Brazil’s achievements over the past 70 years have been closely linked to the development of hydraulic infrastructure for hydroelectric power generation and just recently to the development of irrigation infrastructure, especially in the Northeast region.

Two challenges in water resources management stand out for their enormous social impacts: (i) unreliable access to water with a strong adverse impact on the living and health standards of the rural populations in the Northeast where two million households, most in extreme poverty, live, and (ii) water pollution in and near large urban centers, which compromises poor populations' health, creates an environmental damage, and increases the cost of water treatment for downstream users.

As in many other countries, water resources management in Brazil has historically relied upon heavy investment on hydraulic infrastructure. From building the first hydropower facility in 1901 until the mid-1970s, hydropower has been the main focus of water resources management. In 1934, after several modifications introduced to the first 1907 draft, the Water Code was approved. The Water Code was the first legislation for water resources management in Brazil, and was applied for more than 60 years. The Water Code ensured the free use of any water for basic life necessities and permitted everyone to use any public water while complying with administrative regulations. Some of its provisions, such as the polluter pays principle, were introduced long before this principle became globally recognized as a good practice.

The intention of reforming Brazil’s water resources management system began to shape during the 1970s when other water users challenged the priority given to hydropower. Different initiatives and institutions for water management were established by the Federal Government and states such as São Paulo and Ceara. The Constitutional reform of 1988 was the first step in the creation of a National Water Law, whose responsibility was given to the Federal Government. The reformed Constitution also established a distinction between federally controlled water, for rivers across state boundaries, and state-controlled water, for rivers and groundwater that remained completely within state boundaries. Based on this new responsibility, the states began to implement their own water resources management systems. São Paulo pioneered this process in 1991 (see Water management in the Metropolitan Region of São Paulo). Today 25 of Brazil’s 26 states and the Federal District have adopted legislation to modernize water resource management (see States of Brazil).
