The world has a long experience of using harvested rainwater from rooftop catchments in urbanized regions. There are also many studies about the technical, health, and environmental details of such systems. The gradual prevalence of rainwater harvesting systems in the country exposes a necessity to determine and define some guidelines and instructions for health and environmental considerations of these systems. Therefore, this study was aimed at introducing some existing health and environmental instructions regarding extracted water from rooftop catchments for drinking purposes in Aq Ghala, Golestan province, Iran. Results revealed that water samples had a good physical and chemical quality for drinking purposes which was established by another work in Golestan province with 140 samples’ analysis. This work confirms that there is a need to prepare health and environmental instructions for rooftop catchment systems before developing them.
