Although I have a dry basement, it does get "humid" down there when it rains. So, we have a good humidifier to deal with any dampness. To avoid emptying the bucket all the time, we mounted the humidifier on a platform about eye-high so we could run a plastic tube from the humidifier over to the set-tub we have in the laundry area. Works great!
