The estimate of the World Health Organization (WHO) is that around 2025 the world population will be 8.9 billion and, for this population that will be the maximum amount of water that will supply the land. Due to the increase in population, the building of Wastewater Treatment Plants is a crescent concern, as well as a big challenge to the society, because in localities lacking schools, hospitals, safety, and appropriate means of transportation, etc., there is a difficulty in convincing the society and the government to apply funds in depolluting water bodies. The State has the duty to collect and treat sewage. This situation requires that a planning and design that enable lower cost of deployment and operation of treatment systems desired. Besides the importance in seeking treatment systems that provide lower costs, it is essential that the effluent achieves the characteristics required by established law, always aiming at the conservation and recovery of water resources. The majoraty of Wastewater Treatment Plants in Brazil, does not have a specific step for disinfection. The adoption of a disinfection system should be preceded by a risk-benefit study. What treatment class, applied technology, disinfectant to be used and the removal level are the main points to be observed. Thus, this research proposes: is to study the disinfection of sanitary effluent from Wetland treatment through a chemical process widely used by numerous advantages which is the chlorination, using as reagent sodium hypochlorite for later reuse at Universidade Estadual Paulista "Julio de Mesquita Filho, "Campus de Bauru-SP.
