Over 11 percent of the world's population does not have sufficient access to clean drinking water. This mainly affects structurally weak regions, such as Africa and Central Asia. However, it is also increasingly a global problem. The question is, how can the global drinking water situation be secured on a nationwide basis? Inflotec has developed a unique, ingenious and sustainable off-grid system for this purpose. Any polluted surface water can be treated into drinking water solely by the forces of nature (use of water, wind or solar energy).
