What is rainwater capture
Rainwater Capture (Rainwater Harvesting) is the collection and reuse of rainwater.
Rainwater is collected from the roof and other surfaces and reticulated into the storage tank where it is stored for direct use.
Rainwater may also be purified and reintroduced as potable water.
How to work out the potential water to be collected through rainwater capture
- 1mm of rainfall ON 1 m² roof area = 1 litre of harvested water
- Kwazulu Natal has an average rainfall of 1000mm per year.
- This means that if you have carport area of say 50m², then the water captured over a year could be 50 000 liters or 50 kiloliters*
*Calculation (1 000mm X 50m² = 50 000 liters)
