Once untreated, wastewater that is produced by various industries can be highly hazardous for nature, contaminating water sources and the earth.

According to UNESCO's report, about 80% of the world's wastewater is not treated. Access to safe water is a rising issue, as UNESCO shows that 4.5 billion people in the world lacked safely managed sanitation facilities in 2015, which is an ongoing problem for many regions of the world as we have 784 million people who live without basic access to clean water
