22 March 2017 Current Affairs: The World Water Day (WWD) was observed globally on 22 March 2017 with theme Why Wastewater? The year’s theme for the world water day focuses on wastewater and ways to reduce and reuse as over 80 per cent of all the wastewater.
The theme highlights that wastewater flows from homes, cities, industry and agriculture to nature. This free or untreated flow helps in polluting the environment leading to loss of valuable nutrients and other recoverable materials.
Motto behind the theme Why Wastewater?: The theme seeks to improve the collection and treatment of wastewater and safe usability of the same. At the same time, it wants to make us (people) learn the art of reducing the quantity and pollution load of wastewater that we produce. The effort will help us in protecting the environment and water resources that are available to us.
Save water is also a goal enshrined in the Sustainable Development Goal. The Sustainable Development Goal 6 – ensuring availability and sustainable management of water and sanitation for all by 2030 - includes a target to halve the proportion of untreated wastewater and increase water recycling and safe reuse.
Water is the essential building block of life. Apart from being an essential source to quench thirst or protect health, water also acts as a source that supports economic, social and human development goals by creating jobs.
Water should be protected from being wasted because, today, there are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water.
Globally, over 80 per cent of the wastewater is generated by society. This wastewater flows back into the ecosystem without being treated or reused. (Sato et al, 2013)
1.8 billion people use a source of drinking water that is contaminated with faeces. This contamination put them at risk of contracting cholera, typhoid, dysentery and polio. Unsafe water, poor sanitation and hygiene cause around 842000 deaths each year. (WHO/UNICEF 2014/WHO 2014)
The opportunities for exploiting wastewater as a resource are enormous. Safely managed wastewater is an affordable and sustainable source of water, energy, nutrients and other recoverable materials.
The first World Water Day was observed on 232 March 1993. Earlier, an international day to celebrate a day of freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro. The recommendation was responded by designation 22 March as a World Water Day by adopting a resolution A/RES/47/193 of 22 December 1992 by United Nations General Assembly (UNGA).
