Rainwater Harvesting as a solution to Angola’s water problem
The harvesting of rainwater entails the collection and storage of rainwater in suitable containers, etc. water storage tanks or reservoirs. Rainwater is considered pure because it is free from pollutants, salts, minerals and man-made contaminants. However, millions of litres of rainwater (an estimated 70%) that is perfect for household, agricultural, industrial and commercial use, are lost every year due to the water simply being soaked up by the ground or evaporating into the air . This is a problematic situation that can largely be alleviated by the harvesting of rainwater via a Rainbow Reservoir tank.

Should I install various tanks or a single water reservoir?
We are of the opinion that installing a single water reservoir is preferable to installing a number of tanks of the same capacity for the following reasons:
Installing a single reservoir is more cost effective than installing various tanks that make up the same capacity as a reservoir.
Where space is limited it is more effective to install a single reservoir as opposed to an array of tanks of the same volume.
The domed roof of a reservoir offer a large surface from which rainwater can be collected, if fitted with a gutter system.
In areas that are more prone to fluctuations in temperature – we recommend installing a single reservoir because a large body of water is more resistant to variations in temperature than smaller bodies of water contained in a number of tanks.
