Notice and timing
How delinquency is handled
Grace period after the due date
More than 30 days past due places an account in delinquent status. The public FAQ does not promise a separate grace period after the printed due date; any unpaid past-due balance is subject to disconnection at any time.
Late-fee calculation
The reviewed 2026 customer FAQ does not publish a separate percentage late charge. It states that unpaid bills more than 30 days past due are delinquent, that customers are notified by phone call and letter, and that a missed payment on an installment arrangement immediately fast-tracks the account back into disconnect status. Returned checks are subject to a $37 fee according to the published miscellaneous-fee schedule.
Disconnection timeline
The published progression is: the monthly bill shows any past-due amount; once the unpaid balance is more than 30 days past due the account is delinquent; the customer receives phone and letter notification; and an unpaid past-due account may then be disconnected at any time. The official FAQ does not state a fixed calendar day between the notice and physical shutoff. A payment arrangement can prevent disconnection if maintained, but a missed installment immediately returns the account to disconnect status.
