The Idea is a lot more work than I had planned. I have been playing 25 a lot more lately. After looking at how the constructables work I will be moving to 25 also. The idea came about when looking at road ditches. I am working on making concrete drainage canals( will be on 25 due to better usability) and field tiling. The big picture is fully functional drainage thats weather dependent( I have a 200 page google doc with everything). The full implementation would be on my own map. Your mods would be part of it and the main infrastructure for the map. In order for the pipes to be functional i would have to either override them with lua or modify them to move fluids.
Its a LOT but would be fun on a server where there is a lot of members.
