Notice and timing
How delinquency is handled
Grace period after the due date
20 days from the mailing/billing date without penalty.
Late-fee calculation
A 10% penalty is assessed on the 21st day after the bill is mailed, and a disconnect notice is automatically generated. The city does not publish a separate percentage escalation in the reviewed current FAQ.
Disconnection timeline
Day 0 is the bill mailing date; days 1-20 are the no-penalty period; on day 21 a 10% penalty is applied and a disconnect notice is generated. The reviewed public pages do not give the later calendar date on which the physical shutoff occurs.
