Notice and timing
How delinquency is handled
Grace period after the due date
0 after the due date shown on the bill; ACSA says bills are due when rendered. An outstanding amount at the next billing date is charged the published delinquent penalty and late-payment charge.
Late-fee calculation
ACSA’s current start/stop page states that any outstanding amount at the next billing date is charged a 10% penalty plus a late-payment fee of 1.5% per month. The rules classify an unpaid bill as past due after the due date, and a $35 cash-only returned-payment fee applies to failed checks or electronic transfers.
Disconnection timeline
The bill is due when rendered; an unpaid bill is delinquent and ACSA mails a notice requesting payment. That notice states the date after which the account is subject to disconnection. The public rules do not set one universal number of calendar days because the notice date controls; service is restored only after arrearages and applicable charges are paid.
