| Summary: | Due to the increasing demand, water management is becoming progressively more challenging, especially in urban centers of arid and semi-arid regions. The use of rainwater for potable purposes is an adaptation measure to address climate change and build more resilient cities. The technique of discarding the first millimeter of rainfall to separate initial runoff is a method that makes rainwater fit for potable purposes. This research aimed to assess the quality of rainwater stored in household reservoirs using the DesviUFPE collection and treatment system for automatic disposal of initial runoff. It also aimed to evaluate the compliance of the stored water with potability standards for human consumption in popular urban housing developments in the semi-arid region of Pernambuco, Brazil. To achieve this, samples were collected from 24 residences. The study lasted for 12 months, covering both rainy and dry periods in the region. The following parameters were analyzed: turbidity, hardness, alkalinity, chlorides, electrical conductivity, salinity, total coliforms, and Escherichia coli. Simple disinfection of stored water was necessary for all residences. Thus, the use of the DesviUFPE system in conjunction with chlorination for disinfection proved to be an effective solution to make rainwater potable and suitable for human consumption. |
