Water supply and sanitation in Brazil are characterized by both achievements and challenges. Brazil has made significant progress in increasing access to water supply and sanitation services, but disparities remain, particularly in rural areas and among low-income populations.

Overview

Brazil is the largest country in South America and the fifth largest in the world by both area and population. The country has abundant water resources, but their distribution is uneven, with the majority located in the Amazon Basin, far from the most populous regions.

Water Supply

Water supply in Brazil is managed by a combination of public and private entities. The National Water Agency (ANA) is responsible for the management of water resources at the federal level. Water supply services are provided by state companies, municipal companies, and private operators.

Urban Areas

In urban areas, approximately 97% of the population has access to improved water sources. Major cities like São Paulo and Rio de Janeiro have extensive water supply networks, but issues such as water loss and intermittent supply persist.

Rural Areas

In rural areas, access to improved water sources is lower, with about 85% of the population having access. Challenges include the remote location of many communities and the lack of infrastructure.

Sanitation

Sanitation services in Brazil are less developed than water supply services. Approximately 83% of the urban population has access to improved sanitation facilities, while in rural areas, this figure drops to around 50%.

Sewage Treatment

Only about 50% of the collected sewage is treated before being discharged into the environment. This has significant implications for public health and the environment, particularly in densely populated areas.

Challenges

Several challenges affect water supply and sanitation in Brazil, including:

• Water pollution: Industrial and agricultural activities contribute to the contamination of water sources.
• Infrastructure: Aging infrastructure and lack of investment in new systems.
• Inequality: Disparities in access between urban and rural areas, and among different socio-economic groups.
• Climate change: Increasing frequency of droughts and floods affecting water availability and quality.

Government Initiatives

The Brazilian government has implemented several initiatives to address these challenges, including the National Sanitation Plan (PLANSAB), which aims to achieve universal access to water and sanitation services by 2033.
