Water customers in the City of Dawsonville could soon see a slight rate increase. Council members are considering a proposal presented Monday night by City Manager David Headley that, if approved, would raise average monthly bills between $2.59 and $6.30, depending on water usage. Headley said the proposed increase, which is in line with a 2012 rate study, would generate $43,000 to $48,000 annually to cover maintenance and operations costs.
