In this study an integrated system for rainwater harvesting and ozone treatment has been developed for continuous supply of drinkable water. In the perspective of Malaysian scenario ozone treatment of rainwater is still considered a new approach. This pilot project is launched to justify the reliability, the effectiveness and the economic aspect of ozone treated rainwater. The samples of rainwater were analyzed for both physiochemical and microbiological parameters before and after the ozone treatment. The injection of ozone has shown prominent improvement in both parameters and also the quality up gradation of the original rainwater. The results are encouraging and suggest that the technique is promising to fulfil both requirements continuous supply of rainwater as well as accomplish successful ozone treatment. The system can readily be installed at any location and measurements assure that it could certainly provide an alternative water source when conventional piped supply is unavailable. In the perspective of Green Building scenario this integrated approach of ozone treated harvested rainwater might be able to reduce the impact of environmental factors.
