This study focused on Rainwater Harvesting System that is located at UTHM main campus in Batu Pahat, Johor and its suitability in terms of water quality aspect. The system consists of rooftop, gutters, storage tank and sand filter as a treatment system. Twelve samples (influent and effluent) from six storm events were analysed. Concentrations for all parameters were found to vary greatly between storms. Removals percentages were then calculated and the values (%) were DO (9-16), pH (10-36), Turbidity (61-76), Suspended solids (19-54), and Cuprum (15-53), respectively. Lead (Pb) was also detected but the levels were low (<0.001 mg/l). Based on the findings, sand filter has the potential to be a practical and cost-effective method of treating contaminants for harvested rainwater.
