Property closed. Delinquent water bill pops up

[Sant S.]

I recently closed on a multifamily property. I got my water bill for my first quarter of usage and there is a balance the prior owner did not pay. The city the property closed in has a standard policy that water debt transfers from with the property to the new owner. The seller is refusing to pay. I have spoken to my closing attorney and he indirectly has placed the blame on the title company. Title company is placing the blame on the closing attorney. Who is at fault here in your experience? Who should pay this bill? How should I go about resolving this?
