ᐅ Electrical, water, and sewer lines beneath the garage

Hello everyone,

we want to build a single-family house with a garage on a serviced plot of land. However, the garage is planned to be located exactly between the utility connection points and the utility room. Our municipal water supervisor told us that the water pipe must always be laid straight, following the shortest route, and will therefore run directly underneath the middle of the garage. He doesn’t see any issue with this.

Personally, I’m not very comfortable with that. How would repairs be handled if the pipe ever failed? It seems like it would be completely inaccessible. Is it common practice to lay it straight like this? I understand this approach for wastewater pipes, but I wouldn’t have expected a supply line to have to follow a strictly straight path.

What do you think about this, and how could this be resolved with the garage in place without moving the garage? (Unfortunately, moving the garage is not an option.)

Thanks in advance and best regards

This is common practice. Whether it has to be done, I’m not sure.
If the defect is exactly there, the garage floor will be raised and then excavated accordingly.
But it shouldn’t really matter to you, because all costs will then be covered by the municipality. As far as I know, the handover point is the meter inside the house. This means everything up to the meter belongs to the municipality and must be repaired by them. Everything beyond that is your responsibility.
I wouldn’t worry about it.

... but isn’t the pipe usually installed inside a suitably sized protective conduit anyway? You should be able to access both ends (access holes) and then replace the damaged section beneath the garage, if it ever breaks...

Here in Baden-Württemberg, this is not allowed. The utility connections should preferably not be built over.
That’s why we also installed the piping in a curve. Any extra meters must then be covered by the builder.

@superzapp In our case, the water pipe is a (double-walled) PE pipe.
No protective conduit involved.

Okay. I'm curious to see what our water utility will say. I once spoke with them about wastewater. Flexible is something else :-/
