About World Plumbing Day

World Plumbing Day is observed every March 11 to highlight the role of plumbing in public health, safe water, sanitation and the built environment.

The World Plumbing Council leads the observance and continues to publish annual campaign resources for plumbing organizations and communities around the world.

Why World Plumbing Day matters

The day connects professional plumbing with safe water, sanitation, hygiene, environmental stewardship and resilient communities.

It is a professional and public-awareness observance, not a universal plumbing code or a substitute for local licensing, permitting, inspection or safety requirements.

History of World Plumbing Day

World Plumbing Council material says the Council established World Plumbing Day in 2010, with March 11 fixed as the annual date.

A WPC handbook records that the initiative was launched by the Council’s 2008–2011 Executive Board in October 2009 and that the inaugural World Plumbing Day was held on March 11, 2010.

Current WPC pages continue to organize annual March 11 campaigns, resources and international participation.
