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 for metered accounts enrolled in the Utility Billing Relief Program; the current City FAQ states that nonmetered accounts continue monthly billing and that metered accounts not already billed monthly begin receiving a monthly bill after UBR enrollment. Individual account frequency should be confirmed from the customer statement.
- Rate structure
- Metered water charges based on the City’s annual water rate schedule and billed usage, with separate sewer charges and a water-sewer tax. The current public portal links customers to Water Rates but does not expose the full 2026 rate table in the rendered page. UBR-qualified customers receive 50% of the standard water, sewer, and water-sewer-tax rates for the 12-month enrollment period.
- Wastewater and sewer calculation
- Chicago’s UBR materials describe separate water and sewer charges plus a water-sewer tax and reduce each of those three components by 50% for qualified participants. The current public utility pages reviewed do not publish a winter-average formula, a fixed sewer percentage of water use, or a current 2026 residential sewer calculation; the account statement and City billing department control the exact calculation.
- Meter reading
- The EPA record identifies Chicago as a surface-water community system, but the current City utility pages reviewed do not provide a complete 2026 meter-technology inventory or a universal read calendar. Chicago has both metered and nonmetered accounts; individual reading frequency and whether a premise participates in a meter program should be confirmed from the customer account or bill.
