Narrative:

Aircraft X was inbound on a circling approach. The pilot reported circling east for the runway at which point the local controller who was also assigned controller in charge cleared the pilot to land and turned the runway lights on high. As the pilot was in the left downwind; the pilot provided a bases report of around 1380 ft. As ground control and flight data I began working on submitting the PIREP and cutting a special weather observation. Due to our facilities lack of weather equipment we rely on pireps for more accurate information than the estimates we as a tower are able to provide. While I was recording the ATIS I heard the local controller say; 'he just landed on [the taxiway].' I then observed aircraft X on his landing roll on the taxiway. Looking out the window it is near impossible to tell if an aircraft was lined up for the runway or taxiway due to the close proximity of the surfaces and the vantage point from the tower. Also; it is rare that the facility is operating on the runway we were on during this event.having seen this occur more than once recently at this facility by both training and experienced pilots something must be done! Wrong surface landings were the topic of our FBO and tower meeting this past month and a few recommendations were made including painting the word 'taxi' or the letter of the taxiway for the taxiway. Other more radical suggestions included changing of signage near the runway or removal of [the parallel] taxiway due to the close proximity.

Wrong surface landings were the topic of our FBO and Tower meeting this past month and a few recommendations were made including painting the word 'TAXI' or the letter of the taxiway for the taxiway. Other more radical suggestions included changing of signage near the runway or removal of [the parallel] taxiway due to the close proximity.
