Can a landlord be held responsible for a tenant's utility bill?

Question Details:

A tenant failed to pay a water bill for months. The water was shut off and fees and penalties have been added. The city is now threatening to take me to collections or put a lien on that property if I don't pay the bill. The utilities have never been in my name. The city did a title search to find the owners (me). Can they do that? Am I responsible for that bill? Important Notice
