ZOHO: The rain garden works!

How does the rain garden work?

The rain garden is a green oasis in a stony area. In order to relieve the sewerage system in this densely built-up area, rainwater is collected in the rain garden and discharged with a delay. The rainwater that falls in the garden and on the roof of the Hofbogen is collected in a recessed area in the garden, creating a temporary pond. Thanks to the greenery, the water can then slowly sink into the ground. Part of the rain from the Hofbogen roof is also collected in smart rain barrels in the form of the letters ZOHO. The water in the rain barrels is released to the garden with a delay in dry times.
