Alternative Water Sources (Rooftop Catchment)

Rooftop catchments collect rainwater in simple vessels at the edge of the roof. Variations on this basic approach include collection of rainwater in gutters which drain to the collection vessel through down-pipes constructed for this purpose, and/or the diversion of rainwater from the gutters to containers for settling particulates before being conveyed to the storage container for the domestic use. As the rooftop is the main catchment area, the amount and quality of rainwater collected depends on the area and type of roofing material. Roof catchments should also be cleaned regularly to remove dust, leaves and bird droppings so as to maintain the quality of the product water.There are some areas in Singapore which may already have rooftop catchments, but we want at least the majority, if not all buildings in Singapore, to have rooftop catchments.
