Notice and timing
How delinquency is handled
Grace period after the due date
The bill due date is 20 days after the account is billed. The first delinquent notice is issued 21 days after the original due date, so the published payment window before delinquency is 20 days from billing and there is no separately stated post-due-date grace period.
Late-fee calculation
The City does not publish a percentage interest or universal late-balance penalty on the current delinquency page. Its FY2027 miscellaneous water-fee schedule lists a $22 delinquent-service customer-notice charge and an $80 delinquent-service water-meter-lock charge. The same schedule lists a $35 returned-check/insufficient-funds charge effective July 6, 2026. Customers may resolve delinquency through payment or an arrangement before termination; account-specific balances and other utility charges remain due.
Disconnection timeline
The published sequence is: bill issued; due date 20 days later; first delinquent notice 21 days after the original due date; second delinquent notice 7 days after the first; once an account is delinquent 50 days or older and has received both mailed notices, the outbound system calls and gives 5 days to pay the delinquent portion or make arrangements before termination. In practical terms, the call/termination warning begins around day 50-55 after billing, subject to notice delivery and account handling. If a meter is locked, Tucson code materials state that failure to pay within an additional 7 days can result in account termination, with the full balance required before service is reestablished.
