Short summary
Brazil needs water supply alternatives to meet Sustainable Development Goals and to guarantee access to water for all. Rainwater Harvesting Systems (RHS) are a possible alternative and are one of the important recommendations in the New Brazilian Water and Sanitation Regulation. So it is important to evaluate RHS performance in small and medium cities (with high percentage of people without access to safe water) and the influence of uncertainties, especially in the socio and economic aspects.
