The World Water Day, on 22 March 2017 is dedicated to wastewater with the theme, ‘Why waste water?’ Any used water that comes from our toilets, bathrooms, kitchen, tanneries, textile factories, pharmaceutical factories, automobile repair shops, hospitals, health centers, and diagnostic centers etc is termed wastewater. Depending on the source, wastewater would contain pathogens including drug resistant microbes, heavy metals, toxic chemicals, antibiotics etc. It is estimated that globally 80% of the wastewater flows into the ecosystem without any treatment. Such practice leads to contamination our freshwater bodies, soil and the environment, all of which have a direct impact on health.

This can be addressed by treating wastewater before it is disposed or reused. Treated wastewater can be used for various purposes such as in irrigation, landscaping, municipal cleaning etc. At individual level, we can reduce quantity of wastewater produced and pollution of wastewater by using water efficiently and by avoiding putting too much rubbish, chemicals and detergents down our drains. By turning off tap when not needed (while shaving or brushing) can save millions of liters of water.
