Unfortunately, I haven’t found an answer to my question here yet, so I’m starting a new thread.
We are currently building a new house and are considering whether a rainwater tank would be useful for garden irrigation.
However, we have no idea how many cubic meters are typically needed for watering the garden.
Do you know where I could find this information, or do you maybe have a rough estimate? (We will have about 500m² (5400 square feet) of garden.)
Thank you in advance!

A cistern can never be a bad idea; I, or rather we, should have done that back then as well. I would check with the hardware store for exact figures. I believe the city offers discounts on property taxes for cisterns starting at 2000 liters (530 gallons). The water can be used for cleaning the patio or for plant care. I'm also already considering replacing the much too small rain barrel.
Hello!
So – this summer, a rainwater cistern wasn’t really necessary!
In general, a rainwater or groundwater system always makes sense. For new builds, a capacity of 5,000 liters (1,320 gallons) is common – smaller sizes are usually not practical due to the fixed costs for excavation, pumps, and so on.
Of course, if you have to dig the hole by hand on an existing building…
Would a drilled well be an option? However, that doesn’t help with municipal fees.
Best regards,

I was always advised against it from a financial point of view. Now I checked my energy saving regulations, and it says 1.72 cents per m³ (35 gallons) of water!!!! I’m honestly shocked myself, but a small tank without installation costs starts at around 1000€.
Ecologically it makes sense, but economically it doesn’t.

What does the energy saving regulation have to do with this?
This is a question of costs for fresh water, wastewater, and surface sealing fees – and those add up to euro amounts per cubic or square meter!
I also decided against it for cost reasons (7,000 euros) – but I’m not sure if that was such a great idea.

Since 1000 liters (264 gallons) cost 1.72 cents and the wastewater charge I still have to pay is probably around 5 cents, I don’t have a sealing fee, so I can’t comment on that.
If you can get a tank very cheaply, it’s definitely worth considering. For example, my father was given three 1 cubic meter (35 cubic feet) chemical tanks from an acquaintance.
