World Plumbing Day is an international event, initiated by the World Plumbing Council, held on 11 March each year to recognize the important role plumbing plays in societal health and amenity. The WPC, through its member countries and its partnerships with bodies like the World Health Organisation, works all year round to promote the benefits of safe plumbing, but in 2010 it decided to launch the concept of embedding a single day on the world’s calendar dedicated to plumbing. The international plumbing community, as represented by the Council, has a vital role in promoting the link between good quality plumbing, health, environmental sustainability and, increasingly, economic prosperity. March 11 is marked by celebrations, competitions, seminars, and activities all around the world.  People from within and outside the plumbing fraternity come together to learn, share knowledge, build connections and find opportunities to collaborate to improve the quality of, and access to, fresh water and safe sanitation.
