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.

As far as I know, in many supply areas there is the option to install a second meter (only for garden water) to deduct the amount used for irrigation. It does cost an additional meter fee, but it can be worthwhile.
But how do they measure that if it comes from the cistern? Do you have a wastewater meter where you are?

Oh, right, that makes sense. I just didn’t know that there are also wastewater meters. I’m curious about how they work technically—aren’t they at risk of clogging?
So, you would actually need three meters: one for potable water, one for wastewater, and one for cistern water.
You simply read the potable water meter. Wastewater is measured only by the wastewater meter, but the amount from the cistern meter should be subtracted from the wastewater total.
And then wastewater would have to be so much more expensive for all of this to be worthwhile.

That also seems to vary between municipalities. Until about two years ago, we only paid for wastewater corresponding to our drinking water consumption. After that, we had to declare the roof area due to the use of rainwater (in our case for toilets and washing machine) and now also pay wastewater fees for that area in addition. We do not have a separate meter for this. We built the house in 2002.
