Abstract

Climate change and the increase in the urban population are strong stressors for water resources, making it necessary to discuss the construction of urban systems that are resilient and sensitive to water. In this way, the use of rainwater presents itself as an important alternative for accessing water and reducing pressure in water sources. This research aimed to identify the potential of rainwater harvesting in thirteen cities in the State of Paraíba by means of computer simulations. Twelve scenarios were adopted for each city and it was found that the capture of rainwater in the study sites is feasible to decrease the demand for drinking water, corroborating for the decentralized water supply and the increase of urban resilience. Finally, it is understood that, when added to urban planning, this technology tends to favor less hydric vulnerable cities.
