Rainwater harvesting is active flood protection.

So when I think about how it has been raining continuously here in Saxony over the past weeks, every [Zisterne] would have been full for a long time. The water was standing on the meadows and fields here. Not much seeped away.
At the moment I live in an old mill directly by the stream. Fortunately, the [Talsperren] had enough capacity here, so the stream was full to the brim but stayed in the streambed. In 2002, unfortunately, the purpose of the [Talsperre] was not understood, so it was already well filled beforehand. :(
When I think about the last floods, it always rained for days beforehand or there was such a heavy shower that the ground could not absorb the water quickly enough and the water came down from the fields in torrents.
In both cases, no [Zisterne] helps.

Tear up your sealed surfaces - green the roofs and install grass grid plates and rainwater systems! Every rainwater system is a small retention basin. If some narrow-minded planners, water suppliers and disposers would think about it.... They prefer to build retention basins and dike systems worth billions at the state's expense

Morning!

You surely calculated that. Up to 400 mm of rain fell in one day. So, 121 sqm of roof area plus 36 sqm carport times 0.4 = 62,800 liters! Now let’s assume you have a 60,000-liter rain barrel ;) - what do you do on the next rainy day :p?

These narrow-minded planners who don’t think properly are really a plague :).
