More Information on Rainwater Harvesting: What Exactly is Rainwater Harvesting, Anyway?
Before delving further into the topic, lets first understand what rainwater harvesting is. Well, rainwater harvesting is a method of collection and storage of rainwater into tanks or natural reservoirs. One common method of rainwater harvesting is rooftop harvesting.
Usually when it pours the rainwater decants off your roof, and runs off into your street or yard. With rainwater harvesting your rainwater is collected in cisterns or water storage tanks and stored for future use.
Basic Components A Rainwater Harvesting System Must Include
Regardless of its intricacy, a rainwater-harvesting system will have the following five essential components:
The surface, which directly receives the rainfall and provides water to the system is called catchment area (usually calculated in square metres). This could be a landscaped area, a rooftop or a paved flooring surface.
Downtake Pipes and Gutters
Directs the water from the catchment area to the storage tank.
First Flush Devices and Filters
Filters get rid of dirt, leaves and grit that the rainwater might transport from the catchment surface, before the water enters the storage tank.
First flush devices are valves that ensure flushing out of first spell of rain, which carries a lot of pollutants from catchment surfaces and air.
They can be below the ground or above ground.
Pipe systems that carry the stored harvested water till the point of end-use.
It’s not advisable to use harvested rainwater for dishwashing, cooking or drinking unless water quality issues are confirmed and necessary treatment or purification systems set up.

Garden Harvest: A very simple system that allows the connection of a hose within the tank to provide water for irrigating lawns, gardens, and car washing.
Home Harvest Direct: When the supply of rainwater is exhausted, the 'Backup in a Box' unit uses mains water to replenish the tank. The pump in the tank is then ensured of a constant supply of water to feed washing machines, toilets, garden taps, etc.
Home Harvest Gravity: By using the Rain Director system, rainwater is pumped to a header tank where gravity distributes it to the water appliances. This minimises wear on the pump and pump on/off cycling, reducing energy consumption. The system ensures that the rainwater tank is replenished with mains water once the stored rainwater is exhausted.
