Notice and timing
How delinquency is handled
Grace period after the due date
The bill is due within 25 days of issuance. The City's published delinquency workflow identifies a three-day grace period around the post-due processing step; a bill not paid by the due date is delinquent and can incur a late fee and service interruption. Customers should use the exact due date printed on the bill because billing calendars and notices control.
Late-fee calculation
The 2026 Wichita water ordinance provides that 1.5% of the unpaid balance is added to bills not paid within 25 days of issuance. The City's delinquency process describes the late charge as being applied about four days after the due date, with future bills showing current and overdue balances. Returned checks, rejected telephone payments, and rejected online payments are separately listed at $35 per transaction; a $1 online/IVR convenience fee applies to ordinary electronic payment transactions.
Disconnection timeline
The public City process overview describes this progression: the monthly bill is issued with payment due within 25 days; after the due date, the 1.5% late fee and a past-due postcard are applied; staff encourages contact and offers payment help; when an account reaches the City's shutoff threshold, a shut-off-for-nonpayment order is scheduled, and warning postcards or emails state that service termination is approximately two business days away. The published overview also references accounts 61 or more days past due. A customer who has already received a shutoff order cannot rely on ordinary online payment; the portal disables online payment after the order is generated and the customer must contact the Water Customer Care Center or visit City Hall.
