drainage
In short and in plain language
Drainage means taking rainwater away in a planned way.
The water comes from paved areas, roofs and plots.
It includes slopes, channels, gullies and pipes in the ground. Pits where the water soaks away are part of it too.
Missing or poor drainage can lead to puddles, frost damage or damp cellars.
