Georgia Water & Sewer Bill Calculator
Estimate your monthly water and sewer bill in Georgia based on your water usage, meter size, and local utility rates. Rates reflect typical Georgia municipal utility structures.
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.

- Sewer charges are calculated on 100% of water consumption, which is standard practice for most Georgia utilities without separate irrigation meters.
- Stormwater fees vary widely by municipality; $5.50/month represents a typical residential equivalent unit (REU) charge in Georgia.
- This calculator does not include state or local taxes, franchise fees, capital improvement surcharges, or low-income assistance credits.
- Customers with irrigation meters or separate outdoor meters may have sewer charges calculated differently.
- Average Georgia household uses approximately 3,000–4,500 gallons per month (EPA WaterSense data).
