The current monthly water rates were adopted by the Tucson's Mayor and Council on June 3, 2014, and became effective July 7, 2014. Potable water charges have:
- a monthly service charge which the customer pays regardless of the amount of water used
- usage charges
- a Central Arizona Project (CAP) charge
- a conservation charge
The potable monthly service charge recovers the costs of meter reading, meter maintenance and replacement, billing, a portion of distribution system (pipeline) maintenance, and a portion of the capital costs associated with CAP water and public fire protection. The service charge increased $1.32 per month for a 5/8" meter, the size serving most single family homes. Proportionately larger increases apply for larger meters.
Additional information about how resident, commercial, industrial, and multi-family rates are calculated is available. This includes block rates, base rates, CAP and conservation charges, an overview of Tucson Water's Financial Plan, and more.
