Capture of Roof Water and Recycling
Roof water is a relatively uncontaminated source of water providing the roof
materials are suitable and the building is located in an unpolluted area. This water can be captured, filtered and recycled as a
water source within buildings. In Europe the majority of captured roof
water is used for flushing toilets, washing and irrigation. Uncontaminated
roof water with an UV filter or equivalent can be used as a drinking water source.
As water supplies become scarce the use of roof water for drinking
is increasing accordingly. We recommend the use of low flush toilets, taps, showers and appliances in order to reduce the water
requirements so that the captured roof water can meet a greater proportion of demand.
