Sustainability of Rainwater Harvesting

Water is considered an everlasting free source that can be acquired naturally. Demand for processed supply water is growing higher due to an increasing population. We are now increasingly becoming aware of the importance of water to our survival and its limited supply, especially in such regions as Cape Town, South Africa.

Sustainable use of water could maintain a balance between its demand and supply. Rainwater harvesting (RWH) is the most traditional and sustainable method, which could be easily used for potable and non-potable purposes both in residential and commercial sectors. This could reduce the pressure on processed supply water which enhances the green living.

Astore Keymak Cape Town branch manager Jacques Cilliers says that in his opinion, if the commercial sector such as factories and warehouses started harvesting rain water it could save them thousands of Rands. He gave an example that if you take a 2000 sq. meter factory roof that gets +-10mm of rain they could potentially harvest roughly 20 000 litres of usable water. And all they need to do is connect 3 to 4 10 000L tanks to the gutter system, tie this into their water supply with a peripheral pump and filter system and it will provide them with a similar scenario as municipal water feed. Alternatively they could supply farmers or other organisations/people in dire need of water.
