World Water Monitoring Day
2026-09-18 / Calendar of events

Every year on September 18, since 2003, World Water Monitoring Day has been celebrated.
This environmental holiday, established on the initiative of the American Clean Water Foundation, has now become an informational and educational program aimed at raising public awareness of the problems of the planet's water resources and participating in protection against pollution. The program provides people with the opportunity to carry out basic monitoring of the state of local water bodies and is supported by the Water Environment Federation (WEF) and the International Water Association (IWA).
Initially, World Water Monitoring Day was planned to be celebrated on October 18, in honor of the date of the adoption by the US Congress - October 18, 1972 - of the "Clean Water Act". This document is dedicated to the issues of restoration and protection of national water resources. But over time, the holiday became famous and began to be held in other countries. Therefore, since 2007, its date has been moved forward a month, to facilitate the participation of those countries in whose territories the water in reservoirs already freezes at this time of year.
