Rain Water Harvesting


rainwater tank collects and stores rain water, typically from rooftops via rain gutters. A typical rainwater collection or harvesting tank can yield 2500 litres of water from 25 mm of rain on a 100 m2 roof.

Rainwater tanks are installed to make use of rain water for later use and reduce CWA water use for environmental reasons.

If rainwater is used for drinkingit must first be filtered using a Bio UV Filtration system which will remove bacteria, chemicals and most pathogens. While rain water is pure it may become contaminated during collection. Thus, we strongly advise not to use rainwater for drinking when there is an alternative mains water supply available.
