Every year on March 11, the international plumbing community comes together to celebrate World Plumbing Day. World Plumbing Day is an initiative created by the World Plumbing Council (WPC) in 2010. The day aims to spread awareness of the importance of plumbing and plumbers in protecting public health and improving access to clean water and sanitation facilities. 

According to the WPC, over 1 billion people gained access to piped water supplies between 2000 and 2015 and the global population of people who used safely managed sanitation services increased from 28% in 2000 to 39% in 2015.
