House connection costs for wastewater. Included in the ancillary construction costs with 3.5K.

Thanks for your answers. In my case, the earthworks contractor also made the inspection shaft. And this is located about 2m away from the municipal drainage network. I just can't imagine how that should cost 3500, but one is often surprised in this regard

That can certainly be the case. There is civil engineering involved, breaking up and restoring roads. Permits. And, at least here, one must not forget that the municipal wastewater utility only allows handpicked companies to make connections to their sewer network. That may also play a role in the pricing.

Better be glad to have a general contractor who does not conceal or underestimate such cost blocks!
Just to say something positive for a change

I just didn’t understand it – let’s see how many euros will come out in the end. Thanks for your help

Now I spoke again with the earthworks contractor today and he said that he also connects the wastewater to the local supply network and in his opinion no additional costs are incurred. Have you ever heard that it works like that???

Yes, it was the same with us.

Thanks - that would be nice
