The Power of Rainwater Harvesting: A Simple Step Toward Water Conservation

Water is one of our most precious resources, and with South Africa’s ongoing water challenges, every drop counts. Many people don’t realize just how much water can be saved through rainwater harvesting. Just 1mm of rain on a 1m² roof can collect 1 litre of water—a small change that can make a big difference in long-term water conservation.
By installing a simple rainwater collection system, households can gather and store water for various non-consumption uses such as watering gardens, washing cars, and cleaning surfaces. This reduces dependence on municipal supply and helps preserve water for essential needs.

While rainwater harvesting offers a sustainable solution, another major issue affecting water supply is illegal water connections.
