Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Billing frequency
- Monthly. Tucson Water describes a monthly service charge, monthly water-use blocks, monthly water bill examples, and a due date 20 days after the account is billed.
- Rate structure
- Increasing block tiers with a fixed monthly meter charge and per-CCF surcharges. For FY2027 rates effective July 6, 2026, a common 5/8-inch incorporated residential meter has a $21.72 monthly service charge; single-family usage is tiered at $2.58/CCF for 1-7 CCF, $4.70 for 8-15, $9.23 for 16-30, and $13.65 above 30 CCF. Potable accounts also pay a $1.25/CCF water-supply/CAP fee and a $0.15/CCF conservation fee; the $0.15/CCF green-stormwater fee applies inside Tucson city limits. Taxes vary by municipality. Residential tiers are fixed year-round; commercial and industrial classes have separate seasonal surcharges.
- Residential cost reference
- Approximately $49-$50 per month for about 5,000 gallons (roughly 6.68 CCF) of incorporated single-family potable water on a 5/8-inch meter under the FY2027 schedule effective July 6, 2026, before local taxes and separate sewer/garbage charges. This estimate applies the $21.72 service charge plus approximately 6.68 CCF at the first-tier rate and published CAP/water-supply, conservation, and Tucson GSI fees; actual totals vary by municipality, meter size, taxes, and usage. Tucson's bill guide reports $47.81 at 7 CCF under the prior displayed schedule.
- Wastewater and sewer calculation
- Pima County Wastewater Reclamation calculates the monthly sewer charge using the customer's average water use from the December, January, and February billing periods, because those months generally have less outdoor irrigation. Tucson Water notes that its billing period reflects the prior 30 days, so a December statement can include some November use; Pima County offers an appeal process for customers who believe the winter-average calculation is unrepresentative. Sewer charges are included on the combined utility-services statement but are administered by Pima County, not Tucson Water.
- Meter reading
- Tucson Water is transitioning from traditional monthly meter readings to advanced metering infrastructure (AMI). The City planned an initial Spring 2026 AMI installation for approximately 45,000 commercial, industrial, reclaimed, construction, and City-owned meters, followed by residential installation from 2027 through 2029. AMI meters remotely transmit hourly usage data, enabling high-use notifications, alerts, and online usage monitoring; the customer portal for AMI data is planned for early 2027. Until each location is converted, billing remains based on the existing meter-reading cycle, and the City says customers receive mailed notices and door hangers before installation.
- New-account deposit
- No standard residential startup deposit or credit-check waiver is listed on Tucson Water's current customer-service, start/stop, payment, or miscellaneous-fee pages. The current miscellaneous schedule does list a $1,870 deposit for contractor use of a Tucson Water construction meter; that is a construction-account requirement, not a normal residential account deposit. Customers should confirm any property-specific credit or deposit requirement with Customer Service at 520-791-3242.
- Activation or transfer fee
- The FY2027 Water Service Turn-on Charge is $30 for activating a new customer at an existing location. Tucson Code describes the charge as applying to reactivation or transfer of water service from one customer to another; the fee schedule takes effect July 6, 2026.
