Main water pipe through our garden - overbuilding?

I want to benefit from cheap water supply, but not contribute to it with my property. The German elbow society continues to spread. I throw Basic Law Art. 14 (2) as well as AVBWasserV §8 into the room. It actually says everything there.

Three high-voltage lines, one main water line, three water lines for other houses, and a sewage line for two other houses run through my land. All free of charge. I think that's enough.

Since the municipality doesn't really want to support us much now, I also don't see the point anymore. It has always been more of a giving on our part (including gifted land), but woe if you ever need something now.

you can think about how the status quo might have come about.

According to the OP, the grandfather and previous property owner agreed. I would say it turned out badly. He took over the property with all rights and obligations.

Nonsense. The private property of the OP suffers significant damage, moreover without reason, if a pipeline can be routed on public land.

Significant damage for what reason? That you can't plant huge trees?

In my opinion, it has no place on private land when 5m away there is a public road with a sidewalk.

Just post a floor plan including the pipelines. Basically, you are right. Nevertheless, there are certain exceptions. I still don’t understand what the big problem is. As long as you don’t plant a forest on it, everything is fine. Otherwise, deep-rooted trees and buildings should be avoided. Everything else is fine without permission. But even with a tree, no one will care later.

Exactly one plan is always helpful... if we had a bigger garden, I would definitely plant several trees there. And it would be quite p***ing if that wouldn’t be possible because of a cross (?!?!?) running line.

If grandpa only gave oral consent back then, are there any conversation protocols? Otherwise, people can claim a lot...

According to the OP, the grandpa and previous property owner agreed. I'd say tough luck. He took over the property with all rights and obligations.

Oral agreement without a construction encumbrance in the construction encumbrance register and without a servitude? Not acceptable at all; it is worth less than a fig!

Otherwise, deep-rooting trees and buildings are to be avoided. Everything else is possible without permission. But later on, no one will care about a tree anyway.

We would like to plant one or two apple or cherry trees or also build a garden shed. None of this is possible because the line practically takes up half the garden. I can submit the plan later.

If grandpa only agreed verbally back then, are there any meeting minutes? Otherwise, anyone can claim anything...

No.
