November 19th is World Toilet Day, a day dedicated to celebrating toilets and raising awareness of the 3.4 billion people living without access to safely managed sanitation. 
The theme for 2021 is 'Valuing Toilets.'

At IWA Publishing, we are dedicated to sharing research about water, our most valuable resource, including papers on sanitation, drinking water, drainage systems and more. 

Want to test your toilet and sanitation knowledge? Check out IWAP's annual Toilet Day Quiz, and don't forget to share your score with us on Twitter!
