#### Formula

Total Monthly Bill = Water Base Charge + Water Consumption Charge + Sewer Base Charge + Sewer Consumption Charge + Stormwater Fee (if applicable)

Water Base Charge: Fixed monthly service charge based on meter size (e.g., 5/8" residential meter = $5.00–$9.45/month depending on utility).
Water Consumption Charge (Tiered): Calculated using an increasing block rate structure: Charge = Σ (Usage in Tieri [Kgal] × Ratei [$/Kgal]) Where usage is measured in thousands of gallons (Kgal) and each tier has a progressively higher rate.
Sewer Base Charge: Fixed monthly sewer service charge (mirrors water base charge at most Georgia utilities).
Sewer Consumption Charge: Billed at 100% of metered water consumption: Sewer Consumption = Total Water Usage [Kgal] × Sewer Rate [$/Kgal]
Stormwater Fee: Flat monthly fee (~$5.50) charged by many Georgia municipalities for stormwater management infrastructure.
