An overview of urban drainage systems and their management in Brazil

Urbanization is closely linked to the history of humanity, from nomadic peoples to the present day. Water has always played a crucial role in the founding and development of cities, influencing not only survival and agriculture, but also sanitation. The Roman Empire was a milestone in the development of urban sanitation, with the implementation of sewage systems and public bathrooms. However, despite advances throughout history, many areas still face challenges in accessing basic sanitation, including Brazil, where poor infrastructure is a problem, especially in the North and Northeast regions. Brazilian legislation has established guidelines for the management of urban rainwater, but the misuse of drainage systems continues to be a problem, resulting in pollution and risks to public health.
