World Water Day is celebrated every 22nd of March. To say water is life is never an overstatement. Water supports every aspect of existence; it’s an important supporter of the economy, an essential ingredient in health sector development, etc.
The United Nations’ theme for this year’s water day celebration is “Why Wastewater?”
Wastewater is defined as “a combination of one or more of:
- domestic effluent consisting of blackwater (excreta, urine and faecal sludge) and greywater (kitchen and bathing wastewater);
- water from commercial establishments and institutions, including hospitals;
- industrial effluent, stormwater and other urban run-off;
- agricultural, horticultural and aquaculture effluent, either dissolved or as suspended matter” (Corcoran et al. 2010)
The focus is to create robust discussions around wastewater and provide efficient platforms where wastewater can be channeled to and effectively utilized.
In celebration of the 2017 World Water Day, let me share with you some interesting facts about water:
