Where and how to pay your Tucson water bill
Tucson Water, the city's municipal utility, gives you four main ways to pay your bill. You can pay online through their website at tucsonaz.gov/water, by phone at 520-791-3242, by mail to the address printed on your bill, or in person at the Tucson Water Customer Service Center located at 310 W. Alameda Street during business hours.
Online payment is the fastest route if you want confirmation the same day. You'll need your account number (printed on your bill) and a debit card or bank account. Phone payment works the same way — have your account number ready and expect to speak with a representative. Mail takes 7 to 10 business days to reach the office, so send it early if your due date is close. In-person payment at the Customer Service Center is immediate and gives you a receipt on the spot.
Tucson Water does not charge a fee for any of these payment methods. Some third-party bill payment services (like your bank's bill pay feature) may process the payment for free, but always confirm before you submit, since some charge a small transaction fee.

Reading your Tucson water bill
Your Tucson Water bill shows your account number at the top, followed by your service address and the billing period (usually one month). The bill lists your water usage in gallons, your sewer charge, and any other services like stormwater management. The total amount due and the due date are printed clearly near the bottom.
The usage section breaks down how much water you consumed during the billing period. Tucson Water measures usage in units called "hundred cubic feet" (HCF), where one HCF equals 748 gallons. If your bill shows 10 HCF, you used about 7,480 gallons that month. Residential rates vary depending on how much water you use — the more you use, the higher the per-unit cost, which is called a tiered or increasing block rate structure.
Look for any adjustments or credits listed separately. These might include a meter reading correction, a previous balance, or a credit from a leak adjustment program. If you spot a charge you don't recognize, note the date and amount, then call Tucson Water at 520-791-3242 to ask about it before you pay.
Setting up automatic payments
Tucson Water allows you to set up automatic monthly payments through their website or by calling 520-791-3242. Automatic payment deducts the full bill amount from your bank account on the due date each month, so you won't miss a payment or face a late fee.
To set up automatic payment online, log into your account at tucsonaz.gov/water, navigate to the payment section, and select the automatic payment option. You'll enter your bank account or debit card information once, and the system will process the payment automatically going forward. You can cancel automatic payment at any time through the same website or by calling the customer service number.
Automatic payment is useful if you travel, have an irregular schedule, or simply want one less bill to track. Your bill will still arrive each month so you can review the charges, but the payment happens without you having to take action.
What to do if you receive a high bill or notice a leak
A sudden spike in your water bill usually signals a leak inside your home, in your yard, or at the meter. Check your bill for the usage amount and compare it to previous months. If usage jumped significantly without a change in your household (like adding a pool or lawn), a leak is likely.
To find a leak, turn off all water inside and outside your home, then check your water meter. If the meter is still moving, water is leaking somewhere. Common leak locations are under sinks, behind toilets, in outdoor hose connections, and underground supply lines. If you find and fix a leak quickly, contact Tucson Water to request a leak adjustment on your bill — they may credit you for the excess water if the leak was recent and you can show proof of repair.
If you cannot locate the leak or the bill remains high after checking, call Tucson Water at 520-791-3242 and ask for a meter accuracy check. A representative can review your account history and help you understand whether the reading is correct or whether a meter malfunction is causing the overcharge.
Understanding late fees and service disconnection
Tucson Water charges a late fee if your payment is not received by the due date printed on your bill. The late fee amount varies, so check your bill or call 520-791-3242 to confirm the current penalty. A disconnection notice is typically sent after 30 days of non-payment, and service can be shut off if the account remains unpaid.
If you know you cannot pay by the due date, contact Tucson Water before the deadline. The utility may offer a payment plan that spreads the balance over several months, allowing you to keep service active while you catch up. Payment plans are not automatic — you must request one and the utility must approve it based on your account history and circumstances.
If your service has been disconnected, you'll need to pay the full past-due balance plus any reconnection fee to restore water. Reconnection typically takes one business day after payment is received. Avoid disconnection by reaching out early if you're struggling to pay.
Assistance programs for Tucson water customers
Tucson Water offers a Low-Income Assistance Program (LIAP) that provides bill discounts to households that meet income limits. The program reduces your monthly water and sewer charges by a percentage based on your household size and income. To learn whether your household qualifies, contact Tucson Water at 520-791-3242 or visit tucsonaz.gov/water and look for the assistance program information.
You'll need to provide proof of income (such as recent pay stubs, tax returns, or benefit statements) and proof of residency to be considered. The application process typically takes one to two weeks. Once approved, the discount is applied automatically to your bill each month.
If you are experiencing a temporary hardship and cannot pay your bill, some local nonprofits and community action agencies in Tucson also offer emergency utility assistance. Call 211 (a free helpline) to find organizations in your area that may help with water bills.
Frequently Asked Questions
Can I pay my Tucson water bill with a credit card?
Tucson Water's online payment system accepts debit cards and bank account transfers, but not credit cards directly. If you want to use a credit card, you can pay through your bank's bill pay service or a third-party payment processor, though some may charge a fee. Check with your bank first to confirm whether they charge for utility bill payments.
How long does it take for an online payment to show up on my account?
Online payments typically post the same day you submit them, especially if you pay before 5 p.m. on a business day. If you pay after hours or on a weekend, the payment may post the next business day. You'll receive a confirmation number immediately after submitting, which you can use to track the payment.
What happens if I overpay my water bill?
If you pay more than the amount due, Tucson Water will credit the overage to your next bill. You can also request a refund by calling 520-791-3242, though the utility may hold the credit on your account instead. Ask the representative which option is available when you call.
Can I change my billing date or payment due date?
Tucson Water bills on a monthly cycle based on your meter reading schedule, so you cannot change the billing date. However, you can request a different due date by contacting customer service at 520-791-3242. The utility will let you know what dates are available and whether a change can be made to your account.
What if I move out of Tucson — how do I close my account?
Contact Tucson Water at 520-791-3242 or visit the Customer Service Center to request a final meter reading and account closure. Provide your move-out date and a forwarding address for your final bill. You'll be responsible for water charges up to the date service ends, and any deposit or credit will be refunded to the address you provide.
