Rainy Season

The rainy season are those months of the year with more precipitation (rainfall) and in the states of Minas Gerais and Espírito Santo this is in general the period from October to April. Depending on the intensity of rainfall, some basic services in the municipalities may be affected, such as water supply and urban mobility. Furthermore, damage can occur to activities important for locations, people and the environment.

To streamline the capacity of action for possible damage, the Renova Foundation has developed the Action Plan for the Rainy Season, which has been shared with environmental agencies, public authorities and municipal and state systems of Civil Defense. The document considers various impacts and risks associated with rainfall for those municipalities with a historical connection with the Doce River and have already been receiving preventive actions since the collapse of the Fundão dam.

Considering the rainy season and its associated risks, this time interval is now being monitored as an emergency management process. To implement the action plan, the Renova Foundation has the support of the international consulting firm Witt O’Brien’s, specialized in risk management, emergency management, environmental management and operational safety management.

The implementation of the management and the monitoring of the risks of each municipality are carried out according a specific system, called Operational Command System. According this system, specialized teams work in operational bases covering specified areas and their respective municipalities on various monitoring fronts. The management of the activities by a central base is essential to ensure the necessary alignment and management and organization of information.

All editions of the Doce River Newsletter are available on the Igam website.


The Doce River Newsletter, published weekly by the Institute for Water Management of Minas Gerais (Igam), provides information and updated images of the monitoring points in the Carmo, Gualaxo do Norte and Doce Rivers, which were affected by the collapse of the Fundão dam. The goal is to inform society about the condition of these rivers during the rainy season, which may cause tailings flowing into them, especially in the stretch between the Fundão dam and the hydroelectric plant Risoleta Neves (UHE Candonga), which may pass along the Doce River and possibly get to the coastal region of the state of Espirito Santo.
