A wateringue (also known as a watering or watergang) is a ditch or drainage structure designed to drain marshlands, wetlands, or flood-prone areas located in coastal plains below the level of high tides (polders), in the Netherlands, Belgium, and France.
In northern France, the term "les wateringues" can also refer to "a forced association of property owners",[1] now known as the Intercommunal Institution of the Wateringues, which is responsible for managing interactions between freshwater and seawater.[2]
