Untreated rainwater is not suitable for use where drinking quality water is required, such as bathing, showering and dish washing. how it works ... The rainharvesting process is very straightforward, involving no more than channelling the rainwater from the drain pipes to a storage tank, via a filter. Once stored, a suitable control system is then used to supply the rainwater to the desired services using an electric pump. water available ... The amount of water available for collection depends upon local average rainfall, roof size , drainage efficiency, and the efficiency of the filter being used. Multiplying the roof area in metres, by average rainfall in millimetres, and by the roof and filter efficiency factors gives annual yield in litres. | Did you know?A house in Johannesburg with a 200m2 roof will yield approximately 160 000L of rainwater per year!!
A house in Pretoria with a 200m2 roof will yield approximately 153 000L of rainwater per year!!
Rainwater Harvesting is already common in Europe – about 100,000 systems were installed during 2005/2006.
30% of treated mains water is used to flush toilets - a properly installed rainwater collection system could save all this water.
