Unpaid water bill from previous owner plus water leak

So I pretty much got a home to rent out back in 2020 but I made a rookie mistake by never transferring the water on my company LLC

The old owner's name is still on the bill but there was a water leak for the past couple of months after I took over that I recently fixed last year by calling 311.

But my Tenant's water has gotten shut off because the city never let him transfer it due to the previous outstanding balance and the bill is in the thousands now.

I don't have the money to pay that big of a bill and I'm trying to get his water turned on. What should I do?
