Smart rain barrels

Part of the rainwater from the roof of the Hofbogen is collected in the ZOHO letters. These letters work like rain barrels. The rainwater is directed to the letters and thus does not enter the sewer. The smart system in the letters looks at the weather forecast via the internet. When a heavy shower arrives, it releases its water into the surrounding garden. In this way it creates buffer space for the coming rain shower. During long periods of drought, it retains water to supply the surrounding greenery with water. The system works on solar energy. The 'rain letters' are a water buffer and area marker in one. The design is by Studio Bas Sala. The production was carried out in collaboration with Wijkcoöperatie Rotterdam Noord and volunteers from Rotterdam Noord. So it is locally developed and built.
