ᐅ Cistern! I don’t want one, but I am being forced to have it – experiences

Hello everyone,
According to our development plan, installing a cistern is mandatory. From an economic perspective, it doesn’t seem worthwhile; if I had the choice, I would skip it.
I have received the following all-inclusive offers (excavation, pump, etc., everything included):
1. 5200-liter (1375-gallon) cistern, €7,000
2. 2600-liter (686-gallon) cistern, €6,000
There is also the option of installing only the cistern without a usage system to meet the development plan’s requirements. For both offers, I would save about €1,000 on the pump and related equipment. However, this would mean burying something in the ground for €6,000–7,000 without any actual benefit, which is hard for me to accept.
Either way, I would use the cistern only for garden irrigation, with a maximum watering area of 220m² (2370 ft²). A garden water meter will definitely be installed; the fees are about €2 per cubic meter.
For me, only the economic aspect matters. Which option is the most cost-effective? I’m leaning toward the 2600-liter (686-gallon) cistern. Or would it be better to just bury the cistern without any usage?
Thank you in advance.

I have connected all toilets and the washing machine and have a crane in the garden. The roof drains into the cistern. It’s definitely worth it. Especially since it’s the only forward-looking solution. Dry years will become more frequent, and people building a house think spending several thousand euros on a sustainable solution is too much? I don’t understand that. It’s not economically worthwhile. You need several decades to recoup the costs. By then, something in the cistern will have broken. What will happen in the future is uncertain.
A cistern can still be installed later as a worst-case scenario.

Not economically viable A house usually isn't economically viable either. Hopefully, economic efficiency isn’t the only argument. Sending an ambulance to you when you need it isn’t economically efficient either. Nevertheless, it’s a reasonable and forward-looking measure. It’s the same with resource consumption. At first glance, it doesn’t seem economically viable, but it is still a good thing.

Sending an ambulance to you when you need it isn’t economically efficient either. Still, it is a meaningful, forward-looking measure. The same applies to resource consumption. At first glance, it may not be economically profitable, but it is still a good thing. Alright, I don’t want to start a fundamental debate. Right now, I am focused on the specific question described.

And again regarding your own quote: you don’t know whether the cistern will be economically viable. You say the future is uncertain. However, the outlook is not good for wasting drinking water on toilets and other uses. Most likely, the chances are increasing that resources will not remain so readily available.
For personal reasons, I impulsively had too many photovoltaic panels installed on my roof and, out of frustration with a government decision here, I impulsively bought a home battery as well. Two years ago, this really wasn’t economically viable and cost me about 7000 euro. At today’s prices, that spontaneous purchase will probably pay for itself within about 5 to 6 years. I accidentally did everything right and am therefore envied. I was still able to buy at what were then normal, from today’s perspective, bargain prices and earn money through high feed-in tariffs. So it can work out like that.
In my opinion, the best approach is to install your system to be as self-sufficient as possible.
