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; water, sewer, and stormwater are billed on the City utility statement.
- Rate structure
- Flat base charge for the first three 100-cubic-foot units, followed by increasing volume bands; July 1, 2026 rates vary by meter size and in-city/out-of-city location.
- Residential cost reference
- For a standard in-city 5/8-inch meter, the water base is $10.37 for the first three units; additional residential units are $3.72 in the next band, before sewer and stormwater.
- Wastewater and sewer calculation
- Sewer has a meter-size/location base fee plus $5.38 per 100-cubic-foot unit in-city or $9.18 out-of-city; water consumption is the usage basis, and stormwater is separate.
- Meter reading
- Columbia publishes separate standard-meter and AMI-meter rate tables; the reviewed pages did not identify one universal AMI vendor or read interval.
