Notice and timing
How delinquency is handled
Grace period after the due date
21 days from the invoice/billing date; the 2026 rate sheet says a 10% late fee applies to unpaid balances 21 days from the billing date.
Late-fee calculation
A 10% late fee applies to unpaid balances after 21 days from the billing date. The reviewed official materials do not state a lower cap, waiver rule, or escalating interest schedule beyond the 10% charge.
Disconnection timeline
The 2026 rate sheet states an impending-lock notice at 30 days from the bill date. If the account remains delinquent, the listed lock/reconnection charge applies; the reviewed materials do not publish the exact physical-lock date beyond that notice milestone.
