World Water Monitoring Day 2025 Observed Globally on September 18.

Important Days | Dated: 23 Sep 2025

World Water Monitoring Day (WWMD) 2025 was observed across the globe on 18 September to raise awareness on water quality issues, encourage public participation in protecting water resources, and highlight the importance of sustainable water management.

🎯 Key Highlights:

  • - WWMD was established in 2003 by the American Clean Water Foundation (ACWF) as a global educational initiative. The first observance took place on 18 October 2003, aligning with the United States Clean Water Act of 1972.
  • - Initially observed on 18 October, the date of WWMD was officially changed in 2007 to 18 September to engage wider global participation, especially among students, before schools closed in October.
  • - The program was later renamed the EarthEcho Water Challenge (EEWC), earlier known as the World Water Monitoring Challenge (WWMC), to promote public engagement and global awareness in water conservation and sustainable use.

💡 Other Important Facts:

  • (i) In 2006, the coordination of WWMD shifted from ACWF to the Water Environment Federation (WEF) and the International Water Association (IWA). Later in 2015, EarthEcho International, an environmental non-profit, took over coordination.
  • (ii) The EarthEcho Water Challenge is held annually from March 22 (World Water Day) to December 31. It enables youth and community scientists to test water quality, share results globally, and advocate protective measures.
  • (iii) Through the Water Challenge Ambassador Program, EarthEcho International trains and supports young leaders aged 14–22 to safeguard local water resources. In 2025, 43 new Ambassadors were selected, joining 11 returning youth leaders, continuing their impact for another year.
