Notice and timing
How delinquency is handled
Grace period after the due date
Bills are due on the 15th; the published schedule applies a 10% penalty after the 15th rather than describing a longer grace period.
Late-fee calculation
A 10% penalty is added after the 15th due date. Returned-check fees are published as $30, $40, or $50 depending on the returned payment amount. A $35 nonpayment-disconnect service charge is also listed.
Disconnection timeline
A dedicated this detail was not publicly posted. The reviewed Destin Water Users material specifies the nonpayment-disconnect fee but does not publish an exact calendar-day progression from due date to physical shutoff.
