I really like the concept of the Terrapumps, but much like the vanilla counterpart, I felt like it takes them too long to complete...
So I made this mod! It allows you to adjust the time they take to reach the max radius, default value is 15 days, from 60. You can see how it looks like in the screenshot, settings are found clicking on the + button in "Mod Options"
Inspired by [WD] Fast Moisture Pumps, which I definitely recommend!
They are still not minifiable though, which I consider a balance price. Have fun!
