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. CPAU typically reads utility meters monthly and bills water, wastewater and other utility consumption for that period.
- Rate structure
- Metered monthly water service with rate-plan and volume-based charges; current FY2027 rate changes were proposed to begin July 1, 2026. The reviewed rate page does not reproduce the complete applicable July 2026 residential water table.
- Wastewater and sewer calculation
- CPAU bills wastewater as a separate utility service. The reviewed current pages do not state a universal 2026 residential sewer winter-average formula or flat percentage; the applicable rate plan and volume basis appear on the City's current rate schedule.
- Meter reading
- CPAU typically reads utility meters monthly. Single-family customers with AMI receive continuous-use email alerts beginning in October 2024; customers without AMI receive billed-usage alerts, and the reviewed pages provide a Customer Reads Own Meter option.
- Activation or transfer fee
- The City provides start/stop/change service through MyCPAU and states that payment is not necessary while initiating an account; the reviewed pages do not expose a universal 2026 activation or transfer fee.
