Abstract Rainwater is pure when formed in the cloud, but it becomes contaminated or characteristically changed while falling and flowing over any surface due to absorbing various suspended elements present in the air, and the dirt or chemicals present on the surfaces, coming into contact with the rain or rainwater. As a result, it is rarely possible to obtain pure rainwater for direct consumption, particularly water that is collected in buildings of urban areas. Storing rainwater for a long period might cause further contamination due to the growth of various microorganisms in the reservoir. Therefore, after collecting and storing it, it is necessary to purify contaminated rainwater according to the purpose of use. There are various methods of purifying or conditioning water and thus rainwater. In buildings, considering the qualitative and quantitative aspects of water demand, limited methods of treatment and conditioning systems are generally employed in rainwater harvesting. The treatment methodologies generally adopted are screening, sedimentation, filtration, and disinfection. In this chapter, the usually practiced treatment process recommended for different purposes of uses of rainwater in buildings, are discussed. At the end of the chapter, the planning aspects of treatment systems are delineated.
