Water is the essential building block of life. But it is more than just to quench thirst or protect health; water is vital for creating jobs and supporting economic, social, and human development.

World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.

Over 663 million people are living without a safe water supply close to home, some others survive on dirty water which results in ill health.

The United Nations Theme for 2017 is ‘Why Waste water?’

Its focus is on wastewater and ways to reduce and reuse it as over 80% of all the wastewater from our homes, cities, industry and agriculture flows back to nature; thereby polluting the environment and losing valuable nutrients and other recoverable materials.

We need to improve the collection and treatment of wastewater and safely reuse it. At the same time, we need to reduce the quantity and pollution load of wastewater we produce, to help protect the environment and our water resources.

Importance of Water

Water makes up more than two thirds of human body weight, and without water, we would die in a few days. The human brain is made up of 95% water, blood is 82% and lungs 90%. A mere 2% drop in our body's water supply can trigger signs of dehydration: short-term memory, trouble with basic math, and difficulty focusing on smaller print, such as a computer screen.

Daytime fatigue is as a result of Mild dehydration . An estimated seventy-five percent of Americans have mild, chronic dehydration.

The water in our saliva helps facilitate chewing and swallowing, ensuring that food will slide easily down the esophagus. Water also lubricates our joints and cartilages. When dehydrated, the body rations water away from the joints.

Water also regulates our body temperature.
