Abstract

Introduction: According to Census/ IBGE (2010) approximately 1.7 million people live in rural locations in the state of São Paulo. Data from the Paulista Forest Institute shows that in 73% of the restrictive Conservation Units there are traditional populations. Law No. 11.445 / 2007, which establishes guidelines for basic sanitation, defined among others objectives: "to provide adequate conditions of environmental health to indigenous peoples and other traditional populations, rural populations and small isolated urban centers, using solutions compatible with their socio-cultural characteristics" . Wastewater treatment for agricultural purposes reduces the discharge of pollutants into water bodies which reduces pollution costs, contributes to the protection of the environment and public health. Objective: To evaluate the efficiency of a low cost wastewater treatment system composed of filter bed and Solar Disinfection Reactor (SODIS), both models developed by Queluz and Sánchez-Román (2014), for agricultural reuse in rural communities and traditional populations. Material and methods: The system will have three (3) identical filter beds that will be connected separately to the Solar Disinfection Reactors (SODIS) where three effluent levels (10, 15 and 20 cm) will be tested. The behavior of this system will be evaluated every 10 days during the 6-month period. The viability for agricultural reuse will be determined by using the recommended quality standards defined by the World Health Organization (WHO, 2006)
