ᐅ Is a rainwater tank worth it for garden irrigation?

A rain barrel would have been an alternative (in column shape) with a capacity of about 500-600L (130-160 gallons).

Since rain barrels naturally require a lot of space above ground.

Which type of underground water tank would you recommend?

Is a plastic one sufficient?
A flat tank is probably best for retrofitting.
How large should the water tank be?

That’s a rather broad question. So, a general answer: the one that best meets my needs...

Yes, as long as it does not need to be driven over or is located close to building structures.

It depends. You don’t have to dig as deep (we had to dig just over 3 meters (10 feet)), but it requires a lot of surface area. You can’t plant anything with deep roots above it, and it’s best to avoid building anything on top—even a small shed. Installing frost-free pipes later may also be difficult in that location.

There are calculators available—just search online. Compared to forum recommendations, these calculations tend to be conservative (forum users often believe you need much more).

9 am to 7 pm is also a bad time for watering.

You’re right. These times are acceptable now. In June and July, watering was banned from 8 am to 8 pm, which meant getting up at 6 am and not going to bed before 10 pm if you wanted to manage watering properly.

Now I have to jump in here.
I always recommend that instead of just asking questions here (which is almost pointless), you should first know what questions you are asking and why.

We don’t even know your water demand for the garden. Garden or lawn? 1 cubic meter or 5 or 10?
Installation can be easy or difficult, and so on.

I’m actually more interested in the flooring you have installed and the furniture you ordered. Thank you.

Those are my watering times too, no other option.
I don’t quite understand the purpose of restricting watering times. It may ease peak demand, but it probably won’t reduce overall water consumption. Especially automatic irrigation systems can just be reprogrammed and continue as before.

Um, actually, those who water during the day end up using more water overall because most of it evaporates and the plants don’t benefit from it. Makes sense, doesn’t it?
