Water and Sanitation
The North of Brazil has the highest concentration of fresh water in the world. Even so, Amazonian riverside populations lack clean water supply and treatment systems, resulting in poor living conditions. Without clean water, and with rivers polluted by sewage (both domestic and industrial), waterborne diseases such as viruses and acute diarrhea still affect these communities. These diseases, especially diarrhea that increases child mortality, are being reduced through preventive campaigns and adapted sanitation technologies (restrooms, collection systems, water supply and treatment).
PSA has promoted water and basic sanitation since its founding in 1987. The water treatment and supply systems in Western Pará, like other programs, are based on:
- Technological innovation – hybrid systems, powered by solar energy and diesel, supplying entire communities at an affordable cost to the population.
- Decentralization – in the model developed by PSA, each community has its own water supply and distribution system. PSA maps the needs of the community and designs a custom-made project.
- Community participation – the systems are implemented with the help of the communities themselves, who work collaboratively. Along with its partners, PSA purchases the necessary materials and equipment and guides residents during construction.
- Self-management – during implementation, residents receive training and learn about the system in depth, allowing them to manage it themselves. Throughout the implementation process and with the support of PSA, each community creates its own water-use regulations and democratically elects the management board, which oversees the network in a transparent and sustainable manner.
A SUCCESSFUL MODEL
Given PSA’s positive results, many of its solutions are being replicated by the government. In addition to partnerships with city governments, PSA was accredited to promote the Federal Government’s programs for access to water in the region. With this, PSA manages a fund that finances local associations for the construction of restrooms, cisterns and other social technologies. In fact, the hybrid photovoltaic water supply system developed by PSA is being evaluated as a national public policy, which will allow the solution to be included in the portfolio of public investments and disseminated throughout the North and Northeast regions.
In tandem with the implementation of the systems, PSA also works to improve the productive activities of the populations, using the irrigation systems to encourage garden crop raising and to supply planted areas.
