AB: Alarming water shortage and increased water scarcity world wide has led to increased interests in alternative water sources. Rainwater harvesting is one of them which is getting more and more attention. There is a huge potential for generalization and extension of rainwater harvesting system as an alternative water supply. This is especially important for arid and semi-arid regions where the water shortage blocks further social, economical development. Earlier laboratory experiments and field study showed that harvested rainwater requires treatments of different degrees in order to meet the WHO drinking water standards. The main focus of this study is to ascertain the quality of stored rainwater for drinking purposes with emphasis on water disinfection and pollutants removal. A movable, low-cost, fully functional small scale treatment facility is proposed and tested under simulated field condition. A number of actual and potential hazardous pollutants were identified in the collected water samples together with laboratory test. The corresponding water purification procedure and fresh-keeping methods are discussed. The final proposal of this movable facility needs to be further examined to achieve optimal combined treatment efficiency.
