To harvest rainwater for effective and efficient use, it has to be cultured through a proper system of collection and . Following are the components which would make up such a system: catchment, transportation, first flush and filter.
The catchment area of the surface that directly receives the rainfall. This can be an open ground, courtyard or terrace. The water received is then transported from the catchment area though water pipes or to the storage area. In the pipes, the rainwater is passed through the first flush, as the water may contain contaminants from the atmosphere and the catchment roof. Subsequently, it is to remove color, turbidity and bioforms which may be found. Filters can consist of a charcoal filter, sand/gravel filter, PVC pipe filter or a sponge filter or a of these.
