World Plumbing Day - March 11


Show Us How Plumbing is Essential

March 11 is World Plumbing Day... every year, everywhere! It is a date that has been celebrated by the international plumbing community since its establishment by the World Plumbing Council in 2010, and is now a fixture on the calendars of political and social institutions across the globe.

The international plumbing community has a vital role in promoting the link between good quality plumbing, environmental sustainability, economic prosperity, public health and hygiene. World Plumbing Day is a vital way to remember, highlight and promote those links.

All through March, IWSH recognizes World Plumbing Day with an international poster competition for children in 1st to 6th grade (Elementary / Primary school age).
