- Billing frequency
- Quarterly customer charge for a standard 5/8- or 3/4-inch residential meter; consumption is based on meter readings and the City’s bill cycle.
- Rate structure
- Effective July 1, 2026, residential water is an increasing block structure in CCF: $2.86/CCF for 1-9 CCF, $4.58 for 10-18, $10.61 for 19-36, and $22.76 over 36 for Residential 1. The standard residential water customer charge is $33.75 per quarter for 5/8- and 3/4-inch meters. Water-only irrigation use is $13.30/CCF.
- Wastewater and sewer calculation
- Ann Arbor publishes combined water, sewer, and stormwater rate schedules effective July 1, 2026. The reviewed accessible rate page does not expose the complete residential sewer calculation, while the leak policy states excessive usage is billed at an incremental/discounted rate when an adjustment is approved.
- Meter reading
- Rates are based on water-meter readings. The reviewed Ann Arbor public pages do not identify AMI/AMR technology or a universal reading interval.
