Hall County officials want the city of Gainesville to take over its sewer billing, similar to the deal Braselton is making with the city. The issue with the county doing its own billing recently came to a head after angry residents claimed the county overcharged them when new sewer rates took effect. The Hall County Board of Commissioners approved a credit of $18.97 to South Hall sewer customers last week after Public Works Director Ken Rearden reviewed the errors the county made in billing.
