How to Pay Your Tucson Water Bill Online and by Mail

Tucson Water's payment methods and where to send payments

Tucson Water, the city's municipal water utility, accepts payments through three main channels: online through their website, by phone, or by mail. The online portal at tucsonaz.gov/water lets you pay when ready with a bank account or debit card. If you prefer to call, Tucson Water's automated phone system handles payments 24/7 at (520) 791-3242. For mailed payments, send your check or money order to the address printed on your bill — typically Tucson Water, P.O. Box 27210, Tucson, AZ 85726, though you should verify the current address on your statement.

Each method has a different processing timeline. Online and phone payments post to your account within one business day. Mailed checks take 7 to 10 business days to clear, so mail your payment well before your due date if you want to avoid a late fee. Tucson Water charges a 1.5% late fee on balances not paid by the due date shown on your bill.

Key Takeaways

• Pay online at tucsonaz.gov/water with a bank account or debit card, or call (520) 791-3242 to pay by phone — both process within one business day.
• Mailed checks take 7 to 10 business days to process, so send them at least two weeks before your due date to avoid late fees.
• Tucson Water charges a 1.5% late fee on unpaid balances after the due date, so confirm your due date on your bill.
• You can set up automatic payments through the online portal to have your bill paid on the same day each month.
• If you cannot pay your full bill, contact Tucson Water's customer service to discuss payment plans or hardship programs.

Setting up automatic payments to avoid missed due dates

The easiest way to may support your water bill is paid on time is to enroll in automatic payments through the Tucson Water website. Log into your account at tucsonaz.gov/water, select the autopay option, and choose whether you want the full bill amount or a fixed amount deducted each month. You can pick any day of the month for the payment to process, though choosing a date shortly after you receive your bill reduces the risk of overdrafts.

Automatic payments withdraw directly from your checking or savings account. You can pause or cancel autopay at any time through your online account, and you will receive an email confirmation each time a payment is processed. If your bill amount varies significantly month to month, you may prefer to set autopay for a fixed amount and manually pay any difference, rather than risk overpaying.

What to do if you cannot pay your full bill on time

If you are facing a water shutoff or cannot pay your bill in full by the due date, contact Tucson Water's customer service at (520) 791-3242 before your account falls into collections. The utility offers payment plans for customers with past-due balances, allowing you to spread the amount owed over several months while continuing to pay your current bill.

Tucson Water also administers the Low Income Household Water information Program (LIHWAP), which provides one-time bill payment information to households at or below 60% of the area median income. To learn whether you may be may be able to access and how to request information, contact Tucson Water directly or visit the Arizona Department of Housing website for current program details. Payment plans do not require a separate process — you can arrange one by phone the same day you call.

Understanding your bill and due date

Your Tucson Water bill shows your account number, the billing period, the amount due, and the due date in large print near the top. The due date is typically 20 days after the bill is mailed. If you pay by mail, subtract 7 to 10 days from the due date to determine when you should send your check. If you pay online or by phone, you can wait until the day before the due date and still avoid a late fee.

Your bill also itemizes your water usage in gallons, sewer charges, and any taxes or fees. If your usage seems unusually high, check for leaks in toilets, outdoor faucets, or irrigation systems — a running toilet can waste thousands of gallons per month. You can also request a meter test if you believe the reading is inaccurate.

Paying your bill if you do not have online access

If you do not have internet access or prefer not to pay online, you can pay by phone at (520) 791-3242 using a debit or credit card. The automated system is available 24 hours a day, seven days a week, and you will need your account number (found on your bill) and a valid card. A customer service representative can also process a payment over the phone during business hours if you need information.

Tucson Water also accepts payments in person at their customer service office, located at 310 W. Alameda Street in downtown Tucson. Hours vary by season, so call ahead to confirm. Payments made in person are posted when ready, making this option useful if you are paying close to your due date and want to avoid mail delays.

Reconnection fees and shutoff procedures

If your account becomes 30 days past due, Tucson Water will send a shutoff notice. The utility typically shuts off service 10 to 15 days after the notice is mailed. Once service is disconnected, you must pay the full past-due balance plus a reconnection fee (the amount varies but is typically $75 to $150) to restore water. Reconnection usually takes one to two business days after payment is received.

If you receive a shutoff notice, contact Tucson Water when ready to arrange a payment plan or discuss hardship information. Even if you cannot pay the full amount, setting up a plan may prevent disconnection. Once service is shut off, the reconnection fee is non-negotiable and adds significantly to your total cost.
