ᐅ Rainwater storage tank in the garage?

We are currently planning our house and garage.
The garage will be a prefabricated garage from Kemmler.
I came across Kemmler’s rainwater storage solution for the garage by chance on their website. Sounds good, but unfortunately too expensive (2,000).

I like the idea because an outdoor rain barrel is unattractive, not frost-resistant, and we don’t have a water connection in the garage.

I’m considering routing the garage’s rainwater downspout through the garage and installing a rainwater tank myself.

Does anyone have experience with this or any suggestions?

How much does it cost? Does it require a building permit / planning permission?

Well, 2000 € seems a bit expensive to me.

I just did a quick search on Google. The first result says that a 500-liter (135-gallon) tank costs only about 40 €. So where are the remaining more than 1900 € going to be spent? There will probably be a connection to the sewer system anyway, so no additional costs there, and running just a wastewater pipe into the garage shouldn’t be that expensive. Or is it? Considering that I recently buried a 4000-liter (1057-gallon) underground tank myself and had to install new pipes, drainage channels, etc., this whole thing cost significantly less than what is being charged here. However, I did all the work myself. Still, as I said, this seems a bit pricey to me.

For us, the well with a deep well pump, 10 m (33 feet) drilling, pressure switch, and piping for two connections cost just under 1,000 euros. It is cheaper with a domestic water pump system.

But a well is not possible everywhere.

That’s true. However, you can check whether it’s allowed to build a well.

In a hot summer, depending on its depth, the well might not be very useful because it can run dry or be only minimally usable.

I am quoting from the information provided by the Enz district:
Drilling a Well

Extracting and using groundwater requires – in addition to notification – a so-called water law permit. Only in exceptional cases is usage permit-free. For example, this applies when groundwater is extracted in only small amounts to water a private home garden. Using the water for other purposes (e.g., for a swimming pool or irrigating agricultural land) and extracting water beyond a minor amount clearly requires a water law permit.

Section 49 of the Federal Water Act (WHG) and Sections 43, 49 of the Water Act for Baden-Württemberg

Permit: Sections 8 and following of the Federal Water Act (WHG)

Permit-free use, so-called common use: Section 46 of the Federal Water Act (WHG)

It’s best to contact your local municipality for advice.
