Hello,

We have a 450 sqm plot and want a cistern. Is 7cbm enough or is it better to plan for 10cbm right away?

How big are your cisterns?

Best regards,
housedreamer

Maybe I'll once again reveal myself as an uninformed layperson, but isn't it about the sealed area or rather the roof area that needs to be drained?

Oh, it’s simply about: how much water comes in (amount of rain on the area to be drained), and how much water goes out (garden irrigation / domestic waterworks / snow cannon etc.). Not to forget: the overflow of the cistern should definitely occasionally activate, otherwise too much dirt accumulates in the cistern.

We have 4.5 cubic meters – that is enough for pure garden irrigation for us. But it depends on how much you need to moisten, and how intensively you moisten...

You want to you have to? If you don't have to, then calculate carefully, usually it is not worth it.

We have just over 10sqm total volume and 5sqm retention volume. That was the regulation for us. I have already heard everything about this, from "much too large" to "can never be large enough," although I would not support the latter due to the aforementioned overflow. It depends on the points mentioned in previous posts (sealed surface, usage behavior, etc.).

Hello, what does the development plan say?
For us, there was a requirement of 5 cubic meters, we made 6.5, the price for the 1.5 cubic meters was minimal.

What do you want to use the cistern for?
