ᐅ Is an alternative routing of the utility lines possible, as in the drainage application?

Are deviations from the original drainage plan allowed without having to obtain a new approval?

I am considering, contrary to the original drainage plan, not to connect the wastewater pipes from the sanitary fixtures below the slab and then run them to the sewer connection. Instead, I would like to run each pipe separately, directly outside the house. All of this would be installed in a trench around the outside of the house and then routed towards the sewer connection. A friend mentioned that this way, in case of a blockage in the wastewater pipes, it might be possible to access them from outside. Otherwise, if it gets really bad, you might have to break open the slab inside the house to clear the blockage.

Or are such concerns unfounded? Are changes like these normal during construction and can they be handled informally, or should I just discard the original drainage plan?

Thank you very much, and have a nice Sunday.

Who planned it like that?

This is actually the correct way to do it.
With the first option, you save about 20.40€ and that’s why it’s often done by general contractors.
Whether it’s possible to simply change it or if the planning and building permit / planning permission must be amended depends heavily on the federal state and district, so only they can answer that for you.
Who planned the project and who is carrying out the work?

The slope has to be correct; maybe it was planned that way because otherwise the slope wouldn’t work out.

If only it were that simple.

And remove the word “actually,” it doesn’t fit here.
That’s why I’m asking who planned it this way.
It reads as if the homeowner drew and submitted something themselves.

Hello, the main lines were proposed by the general contractor with the note that they could be adjusted later if needed.

Also, if there were ever an issue, it would be possible to inspect the WC connections with a camera and even flush them.

Anyway, to cut a long story short, I will check with the building authority how bureaucratic the process would be to make changes.

Although in the first conversation, they more or less said I could do what I wanted on my property (within the standards and recognized rules of technology).

Well, we’ll see. Thanks for your help.
