Cistern directly on construction road - risk of damage?

A filled cistern withstands more pressure, so fill it

Hmm. I think we're talking past each other.

I'll try with a sketch. As you can see, the construction road is actually a bit short for the back construction area. However, the site manager can live with that. But of course, that also means that the construction road must be driven on all the way to the end. We can't block off any more.

The questions now are,
- can the cistern be damaged? How likely is that?
- can the construction road be damaged (sink) if the cistern stays?
- is it enough to simply fill the cistern with water to sufficiently prevent both?
- isn't there an even greater risk for the construction road if you now dig out, remove, and refill on your own?

Thanks and regards

What purpose will the cistern serve in the future? What material is it made of? If it is no longer needed, what speaks against filling it with soil?

1. Yes, if one drives up 100%
2. Yes
3. Maybe
4. Yes, or compact professionally

It is a PE cistern, which is also intended to be used as a cistern in the future. The position is actually very good. It lies on the boundary between our properties and we would both drain our roofs (at least partially) into it. For later use, relocating it now is also not a problem. Having it done professionally is more so (a financial issue). At least my neighbor always wants to do a lot of the work himself, and since we want to use it together, I feel somewhat pressured by peer pressure. I just don’t know if relocating it now might be even more dangerous. However, I have meanwhile also asked the site manager what he thinks is best.

Update: The site manager also sees the danger more in accidental running over by trucks, construction vehicles, cranes. When the cistern is filled, the lateral pressures should not be so severe. Nevertheless, removal would be recommended, simply because no one can constantly watch to ensure that really no one drives over the cistern. He also trusts us in EL to carry out the removal and refilling of the hole and compaction with a hand tamper.

Question: What does a PE cistern with about 3 m³ actually weigh?
