You can fill your water bottle at Trondheim airport free of charge.
If you take an empty drinking bottle through the security check and want to refill this, you can do this several places in the terminal. In the main terminal on the left after security check, right over Travel Value. To the right after security check, right over gate 33. In the terminal west, at the entrance at the vending machine and at the play area, right over gate 25. At the foreign terminal you will find a filling station in the non-Schengen area right over gate 49. In the Arrivals hall, right over 7-Eleven.Please share
