World Water Day is observed on 22 March to bring more attention to a crisis faced by millions around the world and in India - limited access to fresh and clean water. World Water Day 2017 focuses on wastewater. According to the United Nations, over 80% of all the wastewater from our homes, cities, industry and agriculture flows back to nature polluting the environment and losing valuable nutrients.
