The Cisterns Program seeks to promote access to water for human consumption and food production through the implementation of simple, low-cost social technologies. Established as public policy since 2003, it is regulated by Law No. 12,873 of 2013, Decree No. 9,606 of 2018, and various ordinances and regulatory instructions. It is aimed at low-income rural families (per capita income of up to half the minimum wage) and rural public facilities affected by drought or water shortages, with priority given to traditional villages and communities. To participate, families must be registered in the Federal Government's Single Registry of Social Programs.
