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.
- Rate structure
- Metered municipal water with fixed meter-size charges and consumption rates. The City adopted a revised rate structure under Proposition 218 and publishes current rate information; exact 2026 amounts and tiers should be taken from the linked rate schedule.
- Wastewater and sewer calculation
- Tustin's reviewed water-billing page concerns the City water utility and does not state a residential sewer formula, winter-average calculation or flat percentage tie-in. Sewer service may be provided through a separate regional arrangement; verify the customer's statement.
- Meter reading
- Tustin's Water Billing Division is responsible for meter reading, and the City provides an instructional meter/leak-detection guide. The reviewed pages do not identify AMI/AMR equipment, data interval or fixed reading schedule.
