On the other side I would like to see pipes. I would like to have this "look of industrial".
As said, I played a lot around and I found some rules with them. I need to explain: I tried many setups to see, how I can built a most efficient, nice looking fluid industry. And the result was, that I can always (!) use a system of 4-5 pipes (water to petroleum gas) through the whole factory. And more: I found me more and more often building straight parallel underground pipes, each contains one type of fluid.
I've made some drawing to show the principle:
These aren't notes

Or in other words: I can recommend to built it so, because this always works well, while other setups don't.
But this is not the suggestion.

I think this can replace the need for
- climbing over pipes
- straight pipes on ground level
- extensive underground piping
And it would give the game a much more realistic look.
