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. Phoenix’s current official financing disclosure says all accounts are billed monthly and regular bills are due 21 days after the bill issuance date.
- Rate structure
- Seasonal metered rates with a fixed meter-size service charge, an included monthly water allowance, excess-use volume charges, and a per-unit environmental charge. Effective March 1, 2025 and still shown as current in 2026 materials, a 5/8-inch inside-city residential account has a $4.64 monthly service charge including 5 units/3,740 gallons October–May and 8 units/5,984 gallons June–September; excess volume is $4.93 per unit in the low season, $5.65 in spring/fall, and $6.13 in the high season, while the environmental charge is $0.62 per unit. Outside-city rates are generally 150% of the applicable inside-city rate, subject to the City’s exceptions and taxes.
- Residential cost reference
- Approximately $45–$75 per month for combined water and sewer for a typical single-family customer using about 5,000–7,000 gallons, before any solid-waste charges and depending on the customer’s meter size, season, taxes, and sewer average. The water-only component can be materially lower in a summer month because the 5/8-inch base charge includes 5,984 gallons in June–September; the City separately applies environmental charges to all metered units and computes sewer from the winter average.
- Wastewater and sewer calculation
- Phoenix calculates a residential sewer charge from a percentage of the customer’s average monthly water use during the January–March billing cycle, normally the lowest-use months. The City’s sewer schedule lists a one-family residence at 80% adjusted sewer flow and then applies the applicable sewer rate to that flow; the resulting sewer charge is carried into later monthly City Services Bills. A high winter reading caused by a repaired leak, pool refill, or broken irrigation system can raise the following sewer charge, which is why the City offers a separate Sewer Fee Review. The calculation is not a simple fixed percentage of the current month’s water bill; it is tied to measured winter usage and the published residential sewer schedule.
- Meter reading
- Phoenix bills approximately 465,000 accounts monthly. The current customer guidance says meters use electronic devices and are read by handheld computers or mobile collectors inside meter-reading vehicles, which is Automatic Meter Reading (AMR) and has largely eliminated manual reads. A May 2026 City Council update says Phoenix is transitioning from drive-by AMR to two-way cellular Advanced Metering Infrastructure (AMI), replacing roughly 77,000–93,000 cellular endpoints per year over a transition expected to take up to six years; AMI is intended to provide near-real-time data, leak/abnormal-use detection, and a future daily-use customer portal. Therefore, the 2026 system is mixed and transitional rather than uniformly AMI: monthly billing continues, with AMR readings for much of the inventory while AMI deployment proceeds.
