Really loving your overhaul so far, amazing work! Really impressive to do all that, and its working great.
Just a small suggestion - while ground water bore make sense in the context of Nauvis with all the chemistry going on, I think it actually trivializes a lot of content on other planets. For example, no water management on Muluna and Fulgora make all the oxide asteroid/ice cube loop kind of redundant (if you exclude ALICE rocket fuel), and greatly reduce the steam usage on Vulcanus. I'm not further alone on other planets so far, so cannot comment there yet ;)
My suggestion is actually quite simple: either deactivate the ground water bore on most planets where it don't make sense, or better yet (if not too complicated) make it pump the 'main' underground resource in each planet (naphtha on Fulgora, lava on Vulcanus, water on Gleba/Nauvis, nothing on Muluna...) basically mimicking whatever the off-shore pump in each location, with a lower output of course. Basically making it a Ground 'wathever there is down below' Bore.
Personally, I will keep not using it for the challenge, but please do consider the suggestion to keep each planet challenge at the very least as hard as vanilla.
Keep up the good work, much appreciated!
