Rainwater Harvesting

Rainwater Harvesting, Storing Rainwater

Rainwater harvesting is the process of collecting and storing Rainwater for refuse rather than letting it runoff. The traditional methods of collecting water involve harvesting the rain from the roof. 

This traditional method of gathering water is a viable alternative for supplying households and businesses with water. Rainwater is not just harvested for agriculture purposes. The art of storing Rainwater is a norm in countries like Germany and Australia, and the trend of rainwater harvesting has now started in South Africa. 

Ways of Harvesting Rain Water

Apart from rooftops, here are other common ways of harvesting rainwater:

Paved and Unpaved Areas

Rainwater can be harvested from parks, stormwater drains, landscapes, roads, pavements and other open areas. The benefit of using the ground as a surface for collecting water is it allows more water to be collected. This method works well in areas where rainfall is low.


Lakes, water tanks, ponds and other water bodies are highly capable of storing large quantities of Rainwater. In water harvested via this method can be used for meeting the water requirements of the entire city. 

Stormwater Drains

Many residential colonies have a network of stormwater drains. If areas such as these are maintained well, this is one of the most cost-effective methods of harvesting rainwater that too in large quantities. 

Uses of Collected Rainwater
