After two months when the city of Statesboro’s bills for water and other services went out as much as two weeks late, the bills are back on schedule with those mailed Tuesday morning, said City Clerk Sue Starling. The city installed new billing software on its computer system this summer. Meanwhile, the Water and Wastewater Department brought a spate of newly installed wireless meters into service, and glitches with the readings from these aggravated her billing staff’s transition to the new software, Starling explained.
