I want to reroute an outdoor drain pipe (rain water) to a better location but there is a gas line that is in the path that the drain pipe needs to go. Can I route the pipe below the gas line? I'm open to any suggestions on how to get the pipe routed properly.
Here is my poor illustration and photo to help understand the issue.
are you sure they haven't damaged a drain or water inlet line in the process of installing the gas? if a water inlet line was damaged and is on the inside of the meter it would spin the meter slowly (over say an hour or two) when you don't use any water in the house for that time. i would call the people that did the gas pipe install and ask them to find and fix. they're covered by insurance..and accidents happen.
[edit] maybe they hit a drain pipe instead. whatever the problem, they should fix it. you can't install a pipe in a way as to create a ditch that would cause moisture problems under normal conditions, which includes normal rain. to cause problems the ditch would need a considerable amount of bedding screenings and wrong slope, to start causing problems straight away just from rain infiltration into soil. or do you get five inches of rain each time?
you can't interfere (change) the bedding material (e.g. pouring in cement) so alternatives like french drain or deep auger holes (only if hydrology of the soil allows) are hard work and expensive.
Why do you think the bathtub is not currently vented?
Not all traps need to be individually vented so you're not always going to see a vent if you don't know what to look for. It's a little hard to tell from your photos, but I think your bathtub is wet vented through the kitchen sink:
Please correct me if I've got the arraignment of your pipes wrong.

If it's standard ABS drain pipe, I don't see any reason why this couldn't be done. Your gas line is metal. As long as the plastic stays below it it should be fine. I would contact the gas company and just double check that they're kosher with it. Be sure to call the local utility dig locator and have them mark things too, or you'll be liable for damages.
