Waste not on World Water Day
March 22 is World Water Day, where all human beings are invited to learn more about water-related issues, get inspired and make a positive impact. The international event dates back to 1992 when the United Nations Conference on Environment and Development made a recommendation: Thereafter, in 1993, 22 March was established as World Water Day. UN-Water sets the theme each year, and for 2017, it’s about wastewater.
“We are wasting our water mostly by putting waste into it. One cubic meter of wastewater can pollute ten cubic meters of water.” – Rose George
Globally, the vast majority of all the wastewater from our homes, cities, industry and agriculture flows back to nature without being treated or reused – polluting the environment, and losing valuable nutrients and other recoverable materials. Instead of wasting wastewater, we need to reduce and reuse it. In our homes, we can reuse greywater on our gardens and plots. In our cities, we can treat and reuse wastewater for green spaces. In industry and agriculture, we can treat and recycle discharge for things like cooling systems and irrigation.
By exploiting this valuable resource, we will make the water cycle work better for every living thing. And we will help achieve the Sustainable Development Goal 6 target to halve the proportion of untreated wastewater and increase water recycling and safe reuse.
