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 utility bills. The City’s resident guide describes monthly water and sewer charges and reports consumption in hundred cubic feet, where 1 HCF equals 748 gallons.
- Rate structure
- Three-tier volumetric water-usage structure with fixed monthly water and sewer charges. The City states the lifeline rate is followed by graduated charges above the lower usage thresholds; City Council approved rates through November 1, 2026.
- Residential cost reference
- The City’s current guide estimates an average 6 HCF monthly customer bill at approximately $115 for combined water and sewer, and a conservation-level 3 HCF bill at approximately $60. A 5,000-7,000 gallon household uses about 6.7-9.4 HCF, so the closest published benchmark is approximately $115 monthly before any account-specific adjustments.
- Wastewater and sewer calculation
- Joliet calculates both water and sewer consumption in HCF and applies monthly water and sewer charges. The reviewed official guide does not describe a winter-average calculation; the published average combined bill is based on 6 HCF of usage.
- Meter reading
- Joliet customers can monitor usage in near real time through a web-based Customer Water Portal connected to their water-meter accounts. The reviewed materials do not specify a universal AMI transmission interval or manual-read schedule.
