South Africa is a water scarce country and we simply don't have enough water for a growing demand. The only way we can keep supplying water to everyone is by recycling our water and allowing less and less water to run off into the sea. The problem is that every time the water gets recycled it becomes more and more polluted. Most sewage treatment plants aren't even meeting the very basic standards that are required for water recycling and quite often raw sewage ends up in our rivers.
Wastewater from mines and industry pollute our water even further. The fact is that the water coming out of most taps today has become a health risk instead of a health benefit. Installing a water purifier removes that risk and replaces it with the valuable health benefit that is pure water!
