Aiming to explore the potential fundraising, models used for charging the raw waters of São Francisco, Paraíba do Sul, and Doce rivers were applied and evaluated in the Curema-Mãe D'Água water system, located in semiarid Brazil. The methodology consisted of a bibliographical review, documentary research, system operation modeling, application of models, and critical analysis of operations and collections results, comprising a total of 240 months from 2002 to 2021. When applying the Standard Operational Policy (SOP), the water system did not meet the demands 35.4% of the time. The model with the highest collection was the one used in Paraíba do Sul River (R$ 12.71 million/year). The models applied in São Francisco (R$ 1.37 million/year) and Doce Rivers (R$ 3.58 million/year) presented the lowest collections. The Paraíba do Sul River model provided the highest charging with water abstract and consumption elements. The Doce River model, conversely, delivered the highest values through the effluent discharge element. The analysis of charging results indicates that each model has specific applications and outcomes. None of the models consider eventual water scarcity conditions in their formulations.
