Water consumption in the garden

Hello everyone!

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 thinking about whether a cistern for garden irrigation would be useful.
However, we have no idea how many m³ are needed for garden irrigation.

Do you know where I could find out something like this or maybe you have a number handy yourself? (So we will have about 500m² of garden)

Thanks a lot in advance!

A cistern can never be wrong, I or rather we should have done that back then. I would inquire at the hardware store about exact numbers, the city, I believe, offers discounts for cisterns from 2000L with property taxes. The water can be used for cleaning the terrace or for plant care, I am also already considering replacing the way too small rain barrel.

Hi!

So - this summer a cistern was unnecessary!

Otherwise, a rain/groundwater system always makes sense. For a new building, 5,000 liters is common - smaller is not very useful because of the Ehda costs for excavator, pump, etc.

Of course, if I had to dig the hole with a spade on an existing building.......

Would a borehole work? However, that won't help you with the municipal charges.

Meal time,

I was always advised against it financially. Now I checked my Energy Saving Ordinance, 1.72 cents per m³ of water!!!! I'm surprised myself, but a small tank without installation starts at around 1000€.

Ecologically it makes sense but economically it does not.

Hello, Perlenmann!

What does the Energy Saving Ordinance have to do with that?

This is a question of costs for fresh water, wastewater, and sealing charges – and that comes to euro amounts per cubic or square meter!

I also refrained for cost reasons (7,000 euros) – but I don’t know if that was such a great idea.

Sorry, I meant the Energy Ordinance (energy supplier). Since 1000 liters cost 1.72 cents and the wastewater I still have to pay for is probably around 5 cents. I don't have a sealing charge, so I can't say anything about that. However, if you can get such a container very cheaply, it's definitely worth considering. For example, my father was given three 1m³ chemical containers by an acquaintance.
