Notice and timing
How delinquency is handled
Grace period after the due date
0 days after the established due date for the late-fee rule. Atlanta City Code and DWM's late-fee page say a delinquent water/sewer bill is assessed the late fee when it is not paid by the due date; no additional standard grace period is published.
Late-fee calculation
DWM must charge the greater of $5.00 or 5% of the delinquent water/sewer account balance. DWM states that it previously charged only 5% but is complying with the Code's minimum-dollar rule. The late fee is added to the account balance; payment arrangements, Care & Conserve assistance, and the 2026 PromisePay program may help a customer avoid or manage collection activity, but ordinary past-due bills remain subject to the Code.
Disconnection timeline
No single public calendar-day timeline is published for every Atlanta account. The progression is: the bill reaches its stated due date; a late fee applies to an unpaid balance; DWM sends a notice stating that service may be terminated; if the balance remains unpaid and no approved arrangement or adjustment prevents collection, DWM may turn off service and assess the applicable turnoff/re-establishment charge. The City Code says termination follows notice, but does not state one universal number of days from due date to shutoff.
