Usage tips
Compound word
The word is composed of 'der Regen' (rain) and 'das Wasser' (water). The 's' in the middle is a linking element that connects the two words. So it literally means 'water that comes from rain'.
EXAMPLE
Regenwasser ist oft weicher als Leitungswasser.
Rainwater is often softer than tap water.
Typical collocations
In everyday life, 'Regenwasser' (rainwater) is often used in certain contexts. Typical verbs are 'sammeln' (to collect), 'nutzen' (to use), or 'verwenden' (to use), especially in the context of gardening.
EXAMPLE

Regenwasser vs Grundwasser
groundwater
'das Grundwasser' and 'das Regenwasser' are both water from nature. They can be confused because rainwater can later seep into the ground and become part of the groundwater. But 'Regenwasser' first means the water that comes from the sky as rain, for example onto a roof or into a barrel. 'Grundwasser' is located underground, in soil, rock, or sand, and is often important for drinking water. If you are talking about collecting water after a rain shower, 'Regenwasser' fits. If it is about water underground or wells, 'Grundwasser' fits.
Regenwasser

In dieser Region ist das Grundwasser sehr wichtig für die Trinkwasserversorgung.
