This study investigates water quality in roof storage tanks in Amman and the effect of storage tanks' cleaning on water quality and consumer uses. Chlorine concentrations at a few storage tanks were low. All sampled tanks were free of fecal and total coliform. Cleaning roof storage tanks helps keep total heterotrophic plate count (THPC) at low levels. Total trihalomethane (TTHM) has fluctuated over time. Questionnaires revealed that while the majority of the people clean their roof storage tanks they do not drink the water; however, 85% of the people use the water for cooking.
