10 unit apartment utility costs

[Derrick Brigham]

I could use some comparison numbers for a 10 unit apartment my partners and I are considering buying. What are your utilities in Canton Ohio for apartment buildings? I was given two conflicting numbers for water and sewer. One said $4,000.00 per year the other said about $135.00 per month. Any input would be helpful. 

I already asked for the actual bills from the seller but I would like to see some real examples of others if possible.

Thanks.
