two waste water nibs

we recently purchased a new home and have a question regarding the kitchen sink plumbing.

we have a double sink. the dishwasher drains into a wastewater nib on one drain line. the other drain line has a waste water nib that has a 1/2 inch clear hose attached to it that runs through a drill hole in the bottom of the cabinet. this clear hose is full of water but we have no idea what this waste water is.

any thoughts would be appreciated.

Most likely suspect is the condensate drain from a HE furnace and/or AC expansion coil.

thanks so much for the suggestion. i was able to track the condensate drain from the AC/furnace back under the ceiling insulation to the sink. mystery is solved.
