11 March is World Plumbing Day.

Every 11 March, we celebrate World Plumbing Day—a day to recognize the essential role plumbing plays in protecting public health, advancing water solutions, and powering economic prosperity.

Plumbing is more than pipes and fittings. It is the foundation of safe communities, sustainable innovation, and fulfilling careers. That is why our 2025 World Plumbing Day Theme is “Plumbing is More.” We invite you to help us raise awareness about plumbing’s impact by joining us for Go Blue for Plumbing and sharing our World Plumbing Day resources.
