The World Water Monitoring Day is observed every year on September 18 since 2003 to increase public awareness and involvement in water monitoring and protecting water resources around the world. This day is celebrated to increase public awareness and involvement in water monitoring and protecting water resources around the world. World Water Monitoring Day engages people of all ages in monitoring the condition of local rivers, streams, estuaries and other water bodies. The theme of World Water Day 2021 is valuing water.
The day was established in 2003 by America’s Clean Water Foundation (ACWF) as a global educational outreach program by engaging citizens to conduct basic monitoring of their local water bodies. The event is now coordinated by the Water Environment Federation and the International Water Association.
