It's one of those things that most of us don't think about but would be lost without, and yet many people around the world don't have easy access to clean facilities with good plumbing. This day both celebrates these everyday conveniences and brings awareness to those are still without.

First observed in 2010, March 11th 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.
