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
- Quarterly for typical residential service. Green Bay Water customer materials describe fixed quarterly water charges, and the current rate sheet publishes quarterly rates; some account classes or local billing arrangements may differ.
- Rate structure
- PSCW-regulated fixed meter charge plus public-fire-protection charge plus increasing-block volumetric water rates. The current published rate sheet, effective August 1, 2024 and still the current schedule located for 2026, lists 5/8- and 3/4-inch quarterly fixed water charge of $27.00, quarterly public-fire-protection charge of $8.25, volume at $3.00 per 100 cubic feet for the first 10,000 cubic feet per quarter, $2.89 for the next 140,000 cubic feet, and $2.21 above that. The City separately bills stormwater by equivalent runoff unit.
- Residential cost reference
- Approximate 2026 monthly equivalent for a 5/8-inch residential account using 6,000 gallons per month (about 802 cubic feet): about $57.35 including the published 2026 $13.20 monthly stormwater charge for one ERU, using the current water and sewer schedules and excluding account-specific taxes, special charges, or unusually high usage. The utility states that an average residential customer saw about a $12 increase per quarterly bill when the current water rates took effect.
- Wastewater and sewer calculation
- The water bill combines Green Bay Water drinking-water charges with City of Green Bay wastewater and stormwater charges. The current rate sheet lists a 5/8-inch quarterly sewer customer charge of $42.20 with a 300-cubic-foot minimum allowance, then a combined Green Bay Metropolitan Sewerage District and City sewer volume rate of $6.17 per 100 cubic feet for usage above the allowance. Stormwater is billed separately on the same water bill at $13.20 per equivalent runoff unit per month in 2026. The public materials do not describe a winter-average sewer formula.
