Automated watering at night - does anyone do that?

Hello . You need to get another nickname here ;) Your neighbor will light the bonfire anyway when you lay down grass again I think lawn irrigation is fine as long as it is your own rainwater.

, can answer your questions now himself. I had inquired for him.

Whereas the municipalities actively encourage this.

The municipalities/cities just don’t want to prepare and enlarge their old pipes, shafts, and sewers for frequent heavy rain events. I can understand that, it costs an insane amount of money. The builders should simply let less rainwater into the sewer system! That is much cheaper for everyone... Since the costs for cisterns are hardly likely to pay off in most cases, the builder pays the bill here. Of course, it makes sense to replenish the groundwater by keeping everything permeable... Presumably, the costs for installing cisterns in all gardens are also lower than digging up every street and installing larger wastewater pipes, if you compare those costs to burdening the adjacent residents with the costs of road construction.

Lawn requires between 10-20 liters per m2 per week depending on the type. So your cistern is sufficient for one week for 500-1000m2 of lawn.

No, I had already created the account several years ago when I did the first house planning. I just received the message that my email address is already in use – look, it’s by me :)

The situation of the municipalities is very different. Here with us, you can’t do the communities a bigger favor than to use a lot of water – even though the press currently spreads a different mood, the situation is not everywhere like in e.g. Brandenburg. This does not want to downplay the undoubtedly existing problem of water shortage – only that we simply don’t have it here.

When I consider that I sometimes don't water for weeks while other gardens are already turning brown, my cistern is enough for four weeks without any rain. Let's calculate with 30l/m² during a heavy summer rain, then a single summer rain would refill my cistern halfway.

How is it actually with the use of rainwater, should one install a fine filter to prevent the irrigation systems from clogging?

And last summer? I think you also had no rain for a very long time. Can you refill then?


HeimatBauer is not a new gardener. He actually knows quite well what works or not, and lawn is his hobbyhorse. I've known him for a while from the depths of the WWW.
