Assessment of Rainwater Treatment Using Sand and Gravel Filtration and Chlorine Disinfection for Non-Potable Domestic Reuse

Rainwater, originating from atmospheric precipitation, has historically been used as an alternative source to meet daily water needs. This study aims to analyze the physicochemical and microbiological parameters of rainwater in order to assess its potential for reuse in non-potable domestic applications and outdoor activities. The research focuses on identifying key water quality indicators and evaluating the feasibility of using rainwater for non-potable purposes. Rainwater will be collected from the roof of a residential building, treated through filtration and disinfection processes, and subsequently subjected to laboratory analyses to determine its physicochemical and microbiological characteristics. In the final stage, its reuse potential will be evaluated. Currently, the use of rainwater in households is limited due to non-compliance with certain quality standards. However, in the context of the increasingly severe global water crisis, rainwater could represent a sustainable alternative source, contributing to water security and the conservation of this essential resource for future generations.
